Every single one of those macros can be re-used 58without imposing any restrictions whatsoever on the licensing of the 59generated 'configure' script. In particular, it is possible to use all 60those macros in 'configure' scripts that are meant for non-free 61software. This policy is unusual for a Free Software Foundation 62project. The FSF firmly believes that software ought to be free, and 63software licenses like the GPL are specifically designed to ensure that 64derivative work based on free software must be free as well. In case of 65Autoconf, however, an exception has been made, because Autoconf is at 66such a pivotal position in the software development tool chain that the 67benefits from having this tool available as widely as possible outweigh 68the disadvantage that some authors may choose to use it, too, for 69proprietary software. 70 71This official web site of this project is located at 72<https://www.gnu.org/software/autoconf-archive/>. All available 73information concerning this project is referenced from there. 74 75If you have questions, suggestions, are any other feedback that you'd 76like to share, then please don't hesitate to contact the Archive 77maintainers at <autoconf-archive-maintainers@gnu.org>. 78 79 80File: autoconf-archive.info, Node: Downloads, Next: How to contribute, Prev: Introduction, Up: Top 81 822 Downloading the GNU Autoconf Archive 83************************************** 84 85The macros distributed by the Archive are maintained in a public Git 86repository at 'git://git.sv.gnu.org/autoconf-archive.git'. That 87repository can be cloned anonymously, which is probably the most 88convenient way to access the Archive. Gitweb offers an RSS feed 89(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=rss) for 90subscription that informs about changes to the repository. The same 91information is available via e-mail, too, on the commits mailing list 92(http://lists.gnu.org/mailman/listinfo/autoconf-archive-commits). 93 94For the benefit of everyone who doesn't use Git, traditional release 95archives can be downloaded from any GNU mirror, i.e. 96<http://ftpmirror.gnu.org/autoconf-archive/>. New release are always 97announced on the low-traffic announcements mailing list 98(http://lists.gnu.org/mailman/listinfo/autoconf-archive-announce). 99 100 101File: autoconf-archive.info, Node: How to contribute, Next: The Macros, Prev: Downloads, Up: Top 102 1033 How to contribute to the GNU Autoconf Archive 104*********************************************** 105 1063.1 Macro Format 107================ 108 109Each macro in the Archive has an all-upper-case name with the prefix 110'AX_'. The macro is stored in a file with the same name, in lower case, 111and with the suffix '.m4'. Unless absolutely necessary, the file 112contents should be in ASCII. For example, use apostrophe (U+27) for 113quoting identifiers instead of Unicode quotation mark characters U+2018, 114U+2019. 115 116The file should begin with a header comment containing three named 117sections: synopsis, description, and license. 118 119The synopsis gives a summary of the macro usage and arguments. In this 120section, square brackets ('[]') are used to indicate optional 121parameters, and may be nested. 122 123The description contains a prose description of the macro. It should 124describe the function of the macro, and the meaning of any arguments 125given in the synopsis. The description should also identify: 126 127 * any default macro parameter values 128 * any new '--with' or '--enable' options, and their default values 129 * any argument variables consulted ('AC_ARG_VAR') 130 * any substituted variables ('AC_SUBST') 131 * any defined precompiler constants ('AC_DEFINE') 132 133Macros should be defined with 'AC_DEFUN', using correct quoting. 134Comments should be used liberally within the macro, with 'dnl' used for 135comments at the m4sh level and '#' used for comments at the shell level. 136 137If a macro is renamed, the 'AU_ALIAS' macro should be used to guide 138users of the old name to the new name: 139 140 AU_ALIAS([OLD_NAME], [AX_NEW_NAME]) 141 1423.2 Submitting Macros 143===================== 144 145To submit updates to the Autoconf Archive, please create an issue in the 146patch tracker 147(http://savannah.gnu.org/patch/?func=additem&group=autoconf-archive) and 148attach a (preferably 'git-format-patch(1)'-formatted) patch file. Users 149of 'github.com' may prefer to create a pull request for the Autoconf 150Archive Mirror at Github 151(https://github.com/autoconf-archive/autoconf-archive). Please make 152sure your submission contains the following items: 153 154 * a synopsis that shows how the macro must be be called, 155 156 * a brief description of the macro's purpose, 157 158 * the list of authors (optionally with e-mail addresses), 159 160 * licensing terms, and 161 162 * the m4 source code. 163 164Macros can be submitted under any GPL-compatible free software license 165(https://www.gnu.org/licenses/license-list.html#GPLCompatibleLicenses). 166The Free Software Foundation, however, recommends use of the 167all-permissive license 168(https://www.gnu.org/prep/maintain/html_node/License-Notices-for-Other-Files.html) 169for Autoconf macros. 170 1713.3 Writing Highly Usable Macros 172================================ 173 174Autoconf macros are used in a surprising variety of ways, and a 175well-written macro should be flexible enough to suit all of these uses. 176 177See the Autotools Mythbuster 178(http://www.flameeyes.eu/autotools-mythbuster) for suggestions on how to 179write well-encapsulated, portable macros. 180 181 182File: autoconf-archive.info, Node: The Macros, Next: GNU Free

'varname 1300may still be specified on the make command line and will be appended as 1301usual. 1302 1303As an example usage, consider a project which might benefit from 1304different compiler flags for different components. Typically this is 1305done via target specific flags, e.g. 1306 1307 libgtest_la_CXXFLAGS = \ 1308 -I $(top_srcdir)/tests \ 1309 -I $(top_builddir)/tests \ 1310 $(GTEST_CXXFLAGS) 1311 1312automake will automatically append $(CXXFLAGS) - provided by the user - 1313to the build rule for libgtest_la. That might be problematic, as 1314CXXFLAGS may contain compiler options which are inappropriate for 1315libgtest_la. 1316 1317The approach laid out in the referenced mailing list message is to 1318supply a base value for a variable during _configure_ time, during which 1319it is possible to amend it for specific targets. The user may 1320subsequently specify a value for the variable during _build_ time, which 1321make will apply (via the standard automake rules) to all appropriate 1322targets. 1323 1324For example, 1325 1326 AX_AM_OVERRIDE_VAR([CXXFLAGS]) 1327 1328will store the value of CXXFLAGS specified at configure time into the 1329AM_CXXFLAGS variable, AC_SUBST it, and clear CXXFLAGS. configure may 1330then create a target specific set of flags based upon AM_CXXFLAGS, e.g. 1331 1332 # googletest uses variadic macros, which g++ -pedantic-errors 1333 # is very unhappy about 1334 AC_SUBST([GTEST_CXXFLAGS], 1335 [`AS_ECHO_N(["$AM_CXXFLAGS"]) \ 1336 | sed s/-pedantic-errors/-pedantic/` 1337 ] 1338 ) 1339 1340which would be used in a Makefile.am as above. Since CXXFLAGS is 1341cleared, the configure time value will not affect the build for 1342libgtest_la. 1343 1344Prior to _any other command_ which may set ${varname}, call 1345 1346 AX_AM_OVERRIDE_VAR([varname]) 1347 1348This will preserve the value (if any) passed to configure in 1349AM_${varname} and AC_SUBST([AM_${varname}). You may pass a space 1350separated list of variable names, or may call AX_AM_OVERRIDE_VAR 1351multiple times for the same effect. 1352 1353If any subsequent configure commands set ${varname} and you wish to 1354capture the resultant value into AM_${varname} in the case where 1355${varname} was _not_ provided at configure time, call 1356 1357 AX_AM_OVERRIDE_FINALIZE 1358 1359after _all_ commands which might affect any of the variables specified 1360in calls to AX_AM_OVERRIDE_VAR. This need be done only once, but 1361repeated calls will not cause harm. 1362 1363There is a bit of trickery required to allow further manipulation of the 1364AM_${varname} in a Makefile.am file. If AM_CFLAGS is used as is in a 1365Makefile.am, e.g. 1366 1367 libfoo_la_CFLAGS = $(AM_CFLAGS) 1368 1369then automake will emit code in Makefile.in which sets AM_CFLAGS from 1370the configure'd value. 1371 1372If however, AM_CFLAGS is manipulated (i.e. appended to), you will have 1373to explicitly arrange for the configure'd value to be substituted: 1374 1375 AM_CFLAGS = @AM_CFLAGS@ 1376 AM_CFLAGS += -lfoo 1377 1378or else automake will complain about using += before =. 1379 1380Source Code 1381*********** 1382 1383Download the latest version of 'ax_am_override_var.m4' 1384(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=blob_plain;f=m4/ax_am_override_var.m4) 1385or browse the macro's revision history 1386(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=history;f=m4/ax_am_override_var.m4). 1387 1388License 1389******* 1390 1391Copyright (C) 2013 Smithsonian Astrophysical Observatory 1392Copyright (C) 2013 Diab Jerius <djerius@cfa.harvard.edu> 1393 1394Copying and distribution of this file, with or without modification, are 1395permitted in any medium without royalty provided the copyright notice 1396and this notice are preserved.

On success, it sets the 1924BLAS_LIBS output variable to hold the requisite library linkages. 1925 1926To link with BLAS, you should link with: 1927 1928 $BLAS_LIBS $LIBS $FLIBS 1929 1930in that order. FLIBS is the output variable of the 1931AC_F77_LIBRARY_LDFLAGS macro (called if necessary by AX_BLAS), and is 1932sometimes necessary in order to link with F77 libraries. Users will 1933also need to use AC_F77_DUMMY_MAIN (see the autoconf manual), for the 1934same reason. 1935 1936Many libraries are searched for, from ATLAS to CXML to ESSL. The user 1937may also use -with-blas=<lib> in order to use some specific BLAS library 1938<lib>. In order to link successfully, however, be aware that you will 1939probably need to use the same Fortran compiler (which can be set via the 1940F77 env. var.) as was used to compile the BLAS library. 1941 1942ACTION-IF-FOUND is a list of shell commands to run if a BLAS library is 1943found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it is 1944not found.

Static 3280data initializers like sizeof(int) are unavailable to preprocessor. The 3281macro calculates the values known to compiler's static initializer. 3282 3283Assumptions: The sought value should not exceed 65535. The shell 3284interpreter and the sed utility are expected to exist and work similarly 3285across possible build platforms. 3286 3287Result: The resulting configure script will generate the preprocessor 3288symbol definition: 3289 3290 #define COMPILE_VALUE_<ALIAS> <NUMBER> 3291 3292It was important that the value was embedded into the object file in a 3293predefined byte order during the test. This ensured that the result was 3294independent from the target platform's byte order. 3295 3296The existing AC_CHECK_SIZEOF macro also computes the size of the given 3297type without running the test program. However, the existing macro will 3298produce a piece of configure script that will take the time proportional 3299to the logarithm of the sought value. 3300 3301Example of use in configure.in: 3302 3303 AX_C_COMPILE_VALUE(sizeof(int), sizeof_int) 3304 AX_C_COMPILE_VALUE([sizeof(int[[543]])], sizeof_int543) 3305 3306As a result of running the generated configure script, the following 3307definition will appear in config.h: 3308 3309 #define COMPILE_VALUE_SIZEOF_INT 4 3310 #define COMPILE_VALUE_SIZEOF_INT543 2172 3311 3312Source Code 3313*********** 3314 3315Download the latest version of 'ax_c_compile_value.m4' 3316(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=blob_plain;f=m4/ax_c_compile_value.m4) 3317or browse the macro's revision history 3318(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=history;f=m4/ax_c_compile_value.m4). 3319 3320License 3321******* 3322 3323Copyright (C) 2008 Ilguiz Latypov 3324 3325This program is free software; you can redistribute it and/or modify it 3326under the terms of the GNU General Public License as published by the 3327Free Software Foundation; either version 2 of the License, or (at your 3328option) any later version. 3329 3330This program is distributed in the hope that it will be useful, but 3331WITHOUT ANY WARRANTY; without even the implied warranty of 3332MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

This check is 3442necessary because on some systems (e.g. certain ARM systems), the float 3443word ordering can be different from the byte ordering. In a multi-word 3444float context, "big-endian" implies that the word containing the sign 3445bit is found in the memory location with the lowest address. This 3446implementation was inspired by the AC_C_BIGENDIAN macro in autoconf. 3447 3448The endianness is detected by first compiling C code that contains a 3449special double float value, then grepping the resulting object file for 3450certain strings of ASCII values. The double is specially crafted to 3451have a binary representation that corresponds with a simple string. In 3452this implementation, the string "noonsees" was selected because the 3453individual word values ("noon" and "sees") are palindromes, thus making 3454this test byte-order agnostic. If grep finds the string "noonsees" in 3455the object file, the target platform stores float words in big-endian 3456order. If grep finds "seesnoon", float words are in little-endian 3457order. If neither value is found, the user is instructed to specify the 3458ordering. 3459 3460Source Code 3461*********** 3462 3463Download the latest version of 'ax_c_float_words_bigendian.m4' 3464(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=blob_plain;f=m4/ax_c_float_words_bigendian.m4) 3465or browse the macro's revision history 3466(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=history;f=m4/ax_c_float_words_bigendian.m4). 3467 3468License 3469******* 3470 3471Copyright (C) 2008 Daniel Amelang <dan@amelang.net> 3472 3473Copying and distribution of this file, with or without modification, are 3474permitted in any medium without royalty provided the copyright notice 3475and this notice are preserved.

However, f(va_list va) { 3533&va; } produces broken pointer on some environments such as gcc on 3534x86_64, although { va_list va; &va; } works as expected. See the 3535detection code of this file and any of pages 3536https://www.gnu.org/software/autoconf/manual/html_node/Function-Portability.html, 3537http://gcc.gnu.org/bugzilla/show_bug.cgi?id=14557, and 3538http://gcc.gnu.org/bugzilla/show_bug.cgi?id=20951 for further 3539information. 3540 3541Although C99 does not define the operations f(va_list va) { &va; } and 3542&va itself as standard (footnotes are declared as "normative part, 3543information only"), certain situations need it. This macro provides a 3544type detection about va_list implementation to deal with the operation. 3545 3546Following workaround will probably work on such environments although it 3547does not ensure to be safe and portable.

That mode is quite known by 4435big-endian machines (sparc, etc) however the alpha cpu is little- 4436endian. 4437 4438The following function will test for aligned access to be required and 4439set a config.h define HAVE_ALIGNED_ACCESS_REQUIRED (name derived by 4440standard usage). Structures loaded from a file (or mmapped to memory) 4441should be accessed per-byte in that case to avoid segfault type errors. 4442 4443The function checks if unaligned access would ignore the lowest bit of 4444the address. If that happens or if the test binary crashes, aligned 4445access is required. 4446 4447If cross-compiling, assume that aligned access is needed to be safe. 4448Set ax_cv_have_aligned_access_required=no to override that assumption. 4449 4450Source Code 4451*********** 4452 4453Download the latest version of 'ax_check_aligned_access_required.m4' 4454(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=blob_plain;f=m4/ax_check_aligned_access_required.m4) 4455or browse the macro's revision history 4456(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=history;f=m4/ax_check_aligned_access_required.m4). 4457 4458License 4459******* 4460 4461Copyright (C) 2008 Guido U.

To check for specific API that was added in a later version, 7347use AX_CHECK_GIR_SYMBOLS_GJS. 7348 7349Example: 7350 7351 AX_CHECK_GIRS_GJS([Gdk], [3.0], 7352 [Gtk], [3.0]) 7353 7354NOTE: This macro depends on AX_PROG_GJS. 7355 7356Source Code 7357*********** 7358 7359Download the latest version of 'ax_check_girs_gjs.m4' 7360(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=blob_plain;f=m4/ax_check_girs_gjs.m4) 7361or browse the macro's revision history 7362(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=history;f=m4/ax_check_girs_gjs.m4). 7363 7364License 7365******* 7366 7367Copyright (C) 2013, 2016 Endless Mobile, Inc.; contributed by Philip Chimento <philip@endlessm.com> 7368 7369Copying and distribution of this file, with or without modification, are 7370permitted in any medium without royalty provided the copyright notice 7371and this notice are preserved.

If a valid OpenGL implementation 7389is found, this macro would set C preprocessor symbol HAVE_GL to 1. 7390 7391If either a valid OpenGL header or library was not found, by default the 7392configuration would exits on error. This behavior can be overwritten by 7393providing a custom "ACTION-IF-NOT-FOUND" hook. 7394 7395If the header, library was found, and been tested for compiling and 7396linking the configuration would export the required compiler flags to 7397"GL_CFLAGS" and "GL_LIBS". These two variables can also be overwritten 7398by user from the command line if they want to link against the library 7399they specified instead of having the configuration script to detect the 7400flags automatically. Note that having "GL_CFLAGS" or "GL_LIBS" set 7401doesn't mean it can compile or link with the flags, since it could be 7402overwritten by user. However the "HAVE_GL" symbol and "ACTION-IF-FOUND" 7403hook is always guaranteed to reflect a valid OpenGL implementation. 7404 7405If user didn't specify the "ACTION-IF-FOUND" hook, the configuration 7406would prepend "GL_CFLAGS" and "GL_LIBS" to "CFLAGS" and "LIBS", like 7407many other autoconf macros do. 7408 7409OpenGL is one of the libraries that has different header names on 7410different platforms. This macro does the header detection, and will 7411export the following symbol: "HAVE_GL_GL_H" for having "GL/gl.h" or 7412"HAVE_OPENGL_GL_H" for having "OpenGL/gl.h". To write a portable OpenGL 7413code, you should include OpenGL header like so: 7414 7415 #if defined(HAVE_WINDOWS_H) && defined(_WIN32) 7416 # include <windows.h> 7417 #endif 7418 #ifdef HAVE_GL_GL_H 7419 # include <GL/gl.h> 7420 #elif defined(HAVE_OPENGL_GL_H) 7421 # include <OpenGL/gl.h> 7422 #else 7423 # error no gl.h 7424 #endif 7425 7426On the OSX platform, there's two possible OpenGL implementation. One is 7427the OpenGL that ships with OSX, the other comes with X11/XQuartz 7428(http://www.xquartz.org). To use the xquartz variant, user can use the 7429option -with-xquartz-gl[=path to xquartz root]. By default the 7430configuration will check "/opt/X11", which is the default X11 install 7431location on OSX. 7432 7433Source Code 7434*********** 7435 7436Download the latest version of 'ax_check_gl.m4' 7437(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=blob_plain;f=m4/ax_check_gl.m4) 7438or browse the macro's revision history 7439(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=history;f=m4/ax_check_gl.m4). 7440 7441License 7442******* 7443 7444Copyright (C) 2009 Braden McDaniel <braden@endoframe.com> 7445Copyright (C) 2012 Bastien Roucaries <roucaries.bastien+autoconf@gmail.com> 7446 7447Copyright (C) 2016 Felix Chern <idryman@gmail.com> 7448 7449This program is free software; you can redistribute it and/or modify it 7450under the terms of the GNU General Public License as published by the 7451Free Software Foundation; either version 2 of the License, or (at your 7452option) any later version. 7453 7454This program is distributed in the hope that it will be useful, but 7455WITHOUT ANY WARRANTY; without even the implied warranty of 7456MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

If a valid GLU implementation is found, the configure 7490script would export the C preprocessor symbol "HAVE_GLU=1". 7491 7492If either a valid GLU header or library was not found, by default the 7493configure script would exit on error.

This is useful for including a special features in a 7766 Makefile, which cannot be handled by other versions of make. 7767 * The makefile variable `ifnGNUmake' is set to #, otherwise 7768 it is set to the empty string. This is useful for including a special 7769 features in a Makefile, which can be handled 7770 by other versions of make or to specify else like clause. 7771 * The variable `_cv_gnu_make_command` is set to the command to invoke 7772 GNU make if it exists, the empty string otherwise. 7773 * The variable `ax_cv_gnu_make_command` is set to the command to invoke 7774 GNU make by copying `_cv_gnu_make_command`, otherwise it is unset. 7775 * If GNU Make is found, its version is extracted from the output of 7776 `make --version` as the last field of a record of space-separated 7777 columns and saved into the variable `ax_check_gnu_make_version`. 7778 * Additionally if GNU Make is found, run shell code run-if-true 7779 else run shell code run-if-false. 7780 7781Here is an example of its use: 7782 7783Makefile.in might contain: 7784 7785 # A failsafe way of putting a dependency rule into a makefile 7786 $(DEPEND): 7787 $(CC) -MM $(srcdir)/*.c > $(DEPEND) 7788 7789 @ifGNUmake@ ifeq ($(DEPEND),$(wildcard $(DEPEND))) 7790 @ifGNUmake@ include $(DEPEND) 7791 @ifGNUmake@ else 7792 fallback code 7793 @ifGNUmake@ endif 7794 7795Then configure.in would normally contain: 7796 7797 AX_CHECK_GNU_MAKE() 7798 AC_OUTPUT(Makefile) 7799 7800Then perhaps to cause gnu make to override any other make, we could do 7801something like this (note that GNU make always looks for GNUmakefile 7802first): 7803 7804 if ! test x$_cv_gnu_make_command = x ; then 7805 mv Makefile GNUmakefile 7806 echo .DEFAULT: > Makefile ; 7807 echo \ $_cv_gnu_make_command \$@ >> Makefile; 7808 fi 7809 7810Then, if any (well almost any) other make is called, and GNU make also 7811exists, then the other make wraps the GNU make. 7812 7813Source Code 7814*********** 7815 7816Download the latest version of 'ax_check_gnu_make.m4' 7817(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=blob_plain;f=m4/ax_check_gnu_make.m4) 7818or browse the macro's revision history 7819(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=history;f=m4/ax_check_gnu_make.m4). 7820 7821License 7822******* 7823 7824Copyright (C) 2008 John Darrington <j.darrington@elvis.murdoch.edu.au> 7825Copyright (C) 2015 Enrico M.

This macro allows 8069to wrap around the test so that it doesn't have to be recreated each 8070time. 8071 8072Rather than define -with-$LIBRARY arguments, it uses variables in the 8073same way that PKG_CHECK_MODULES does. It doesn't, though, use the same 8074names, since you shouldn't provide a value for LIBS or CFLAGS but rather 8075for LDFLAGS and CPPFLAGS, to tell the linker and compiler where to find 8076libraries and headers respectively. 8077 8078If the library is find, HAVE_PREFIX is defined, and in all cases 8079PREFIX_LDFLAGS and PREFIX_CPPFLAGS are substituted. 8080 8081Example: 8082 8083 AX_CHECK_LIBRARY([LIBEVENT], [event.h], [event], [], 8084 [AC_MSG_ERROR([Unable to find libevent])]) 8085 8086Source Code 8087*********** 8088 8089Download the latest version of 'ax_check_library.m4' 8090(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=blob_plain;f=m4/ax_check_library.m4) 8091or browse the macro's revision history 8092(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=history;f=m4/ax_check_library.m4). 8093 8094License 8095******* 8096 8097Copyright (C) 2010 Diego Elio Petteno' <flameeyes@gmail.com> 8098 8099This program is free software: you can redistribute it and/or modify it 8100under the terms of the GNU General Public License as published by the 8101Free Software Foundation, either version 3 of the License, or (at your 8102option) any later version. 8103 8104This program is distributed in the hope that it will be useful, but 8105WITHOUT ANY WARRANTY; without even the implied warranty of 8106MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

To make up for it, the malloc 8461function promises to return page-aligned addresses if more than one 8462page's worth of memory is allocated. AX_CHECK_PAGE_ALIGNED_MALLOC 8463checks for this condition and defines HAVE_PAGE_ALIGNED_MALLOC if the 8464condition holds. 8465 8466As an aside, note that valloc'd memory cannot safely be freed on all 8467operating systems. (Again, some flavors of BSD are the troublemakers.) 8468It's best to avoid using valloc in favor of posix_memalign, memalign, or 8469an aligned malloc as detected by AX_CHECK_PAGE_ALIGNED_MALLOC. 8470 8471Caveat: AX_CHECK_PAGE_ALIGNED_MALLOC takes a probabilistic approach. If 8472100 calls to malloc all return page-aligned addresses, it assumes that 8473all calls will behave likewise. It is therefore possible - albeit 8474extremely unlikely - that AX_CHECK_PAGE_ALIGNED_MALLOC can return a 8475false positive. 8476 8477Source Code 8478*********** 8479 8480Download the latest version of 'ax_check_page_aligned_malloc.m4' 8481(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=blob_plain;f=m4/ax_check_page_aligned_malloc.m4) 8482or browse the macro's revision history 8483(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=history;f=m4/ax_check_page_aligned_malloc.m4). 8484 8485License 8486******* 8487 8488Copyright (C) 2008 Scott Pakin <pakin@uiuc.edu> 8489 8490Copying and distribution of this file, with or without modification, are 8491permitted in any medium without royalty provided the copyright notice 8492and this notice are preserved.

Version scripts are 9317used when building shared libraries to bind symbols to version nodes 9318(helping to detect incompatibilities) or to limit the visibility of 9319non-public symbols. 9320 9321Output: 9322 9323If version scripts are supported, VSCRIPT_LDFLAGS will contain the 9324appropriate flag to pass to the linker. On GNU systems this would 9325typically be "-Wl,-version-script", and on Solaris it would typically be 9326"-Wl,-M". 9327 9328Two Automake conditionals are also set: 9329 9330 HAVE_VSCRIPT is true if the linker supports version scripts with 9331 entries that use simple wildcards, like "local: *". 9332 9333 HAVE_VSCRIPT_COMPLEX is true if the linker supports version scripts with 9334 pattern matching wildcards, like "global: Java_*". 9335 9336On systems that do not support symbol versioning, such as Mac OS X, both 9337conditionals will be false. They will also be false if the user passes 9338"-disable-symvers" on the configure command line. 9339 9340Example: 9341 9342 configure.ac: 9343 9344 AX_CHECK_VSCRIPT 9345 9346 Makefile.am: 9347 9348 if HAVE_VSCRIPT 9349 libfoo_la_LDFLAGS += $(VSCRIPT_LDFLAGS),@srcdir@/libfoo.map 9350 endif 9351 9352 if HAVE_VSCRIPT_COMPLEX 9353 libbar_la_LDFLAGS += $(VSCRIPT_LDFLAGS),@srcdir@/libbar.map 9354 endif 9355 9356Source Code 9357*********** 9358 9359Download the latest version of 'ax_check_vscript.m4' 9360(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=blob_plain;f=m4/ax_check_vscript.m4) 9361or browse the macro's revision history 9362(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=history;f=m4/ax_check_vscript.m4). 9363 9364License 9365******* 9366 9367Copyright (C) 2014 Kevin Cernekee <cernekee@gmail.com> 9368 9369Copying and distribution of this file, with or without modification, are 9370permitted in any medium without royalty provided the copyright notice 9371and this notice are preserved.

If 9391the instruction set is supported by the host cpu, the C preprocessor 9392macro HAVE_XXX_INSTRUCTIONS is set to 1. The XXX is up-cased 9393instruction case with dot replaced by underscore. For example, the test 9394for "sse4.2" would export HAVE_SSE4_2_INSTRUCTIONS=1. Also the compiler 9395flag "-msse4.2" would be added to X86_FEATURE_CFLAGS variable, that can 9396be obtained in Makefile.am using @X86_FEATURE_CFLAGS@. 9397 9398If any of the test for the instruction set were succeeded, the configure 9399script would run ACTION-IF-FOUND if it is specified, or append 9400X86_FEATURE_CFLAGS to CFLAGS. If none of the instruction were found, 9401ACTION-IF-NOT-FOUND hook is triggered. 9402 9403This macro requires gcc extended builtin function "__builtin_cpu_init" 9404and "__builtin_cpu_supports" to detect the cpu features.

If nothing was 9464specified when calling configure, it searches first in /usr/local and 9465then in /usr, /opt/local and /sw. If the -with-zlib=DIR is specified, 9466it will try to find it in DIR/include/zlib.h and DIR/lib/libz.a. If 9467-without-zlib is specified, the library is not searched at all. 9468 9469If either the header file (zlib.h) or the library (libz) is not found, 9470shell commands 'action-if-not-found' is run. If 'action-if-not-found' 9471is not specified, the configuration exits on error, asking for a valid 9472zlib installation directory or -without-zlib. 9473 9474If both header file and library are found, shell commands 9475'action-if-found' is run. If 'action-if-found' is not specified, the 9476default action appends '-I${ZLIB_HOME}/include' to CPFLAGS, appends 9477'-L$ZLIB_HOME}/lib' to LDFLAGS, prepends '-lz' to LIBS, and calls 9478AC_DEFINE(HAVE_LIBZ). You should use autoheader to include a definition 9479for this symbol in a config.h file. Sample usage in a C/C++ source is 9480as follows: 9481 9482 #ifdef HAVE_LIBZ 9483 #include <zlib.h> 9484 #endif /* HAVE_LIBZ */ 9485 9486Source Code 9487*********** 9488 9489Download the latest version of 'ax_check_zlib.m4' 9490(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=blob_plain;f=m4/ax_check_zlib.m4) 9491or browse the macro's revision history 9492(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=history;f=m4/ax_check_zlib.m4). 9493 9494License 9495******* 9496 9497Copyright (C) 2008 Loic Dachary <loic@senga.org> 9498Copyright (C) 2010 Bastien Chevreux <bach@chevreux.org> 9499 9500This program is free software; you can redistribute it and/or modify it 9501under the terms of the GNU General Public License as published by the 9502Free Software Foundation; either version 2 of the License, or (at your 9503option) any later version. 9504 9505This program is distributed in the hope that it will be useful, but 9506WITHOUT ANY WARRANTY; without even the implied warranty of 9507MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Due to the various number of 9630minor-version numbers that can exist, and the fact that string 9631comparisons are not compatible with numeric comparisons, this is not 9632necessarily trivial to do in a autoconf script. This macro makes doing 9633these comparisons easy. 9634 9635The six basic comparisons are available, as well as checking equality 9636limited to a certain number of minor-version levels. 9637 9638The operator OP determines what type of comparison to do, and can be one 9639of: 9640 9641 eq - equal (test A == B) 9642 ne - not equal (test A != B) 9643 le - less than or equal (test A <= B) 9644 ge - greater than or equal (test A >= B) 9645 lt - less than (test A < B) 9646 gt - greater than (test A > B) 9647 9648Additionally, the eq and ne operator can have a number after it to limit 9649the test to that number of minor versions. 9650 9651 eq0 - equal up to the length of the shorter version 9652 ne0 - not equal up to the length of the shorter version 9653 eqN - equal up to N sub-version levels 9654 neN - not equal up to N sub-version levels 9655 9656When the condition is true, shell commands ACTION-IF-TRUE are run, 9657otherwise shell commands ACTION-IF-FALSE are run. The environment 9658variable 'ax_compare_version' is always set to either 'true' or 'false' 9659as well. 9660 9661Examples: 9662 9663 AX_COMPARE_VERSION([3.15.7],[lt],[3.15.8]) 9664 AX_COMPARE_VERSION([3.15],[lt],[3.15.8]) 9665 9666would both be true. 9667 9668 AX_COMPARE_VERSION([3.15.7],[eq],[3.15.8]) 9669 AX_COMPARE_VERSION([3.15],[gt],[3.15.8]) 9670 9671would both be false. 9672 9673 AX_COMPARE_VERSION([3.15.7],[eq2],[3.15.8]) 9674 9675would be true because it is only comparing two minor versions. 9676 9677 AX_COMPARE_VERSION([3.15.7],[eq0],[3.15]) 9678 9679would be true because it is only comparing the lesser number of minor 9680versions of the two values. 9681 9682Note: The characters that separate the version numbers do not matter. 9683An empty string is the same as version 0. OP is evaluated by autoconf, 9684not configure, so must be a string, not a variable. 9685 9686The author would like to acknowledge Guido Draheim whose advice about 9687the m4_case and m4_ifvaln functions make this macro only include the 9688portions necessary to perform the specific comparison specified by the 9689OP argument in the final configure script. 9690 9691Source Code 9692*********** 9693 9694Download the latest version of 'ax_compare_version.m4' 9695(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=blob_plain;f=m4/ax_compare_version.m4) 9696or browse the macro's revision history 9697(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=history;f=m4/ax_compare_version.m4). 9698 9699License 9700******* 9701 9702Copyright (C) 2008 Tim Toolan <toolan@ele.uri.edu> 9703 9704Copying and distribution of this file, with or without modification, are 9705permitted in any medium without royalty provided the copyright notice 9706and this notice are preserved.

You can supply extra HEADERS to look into. the check will 9725cycle through 1 2 4 8 16 and any EXTRA_SIZES the user supplies. If a 9726match is found, it will #define SIZEOF_'TYPE' to that value. Otherwise 9727it will emit a configure time error indicating the size of the type 9728could not be determined. 9729 9730The trick is that C will not allow duplicate case labels. While this is 9731valid C code: 9732 9733 switch (0) case 0: case 1:; 9734 9735The following is not: 9736 9737 switch (0) case 0: case 0:; 9738 9739Thus, the AC_COMPILE_IFELSE will fail if the currently tried size does 9740not match. 9741 9742Here is an example skeleton configure.in script, demonstrating the 9743macro's usage: 9744 9745 AC_PROG_CC 9746 AC_CHECK_HEADERS(stddef.h unistd.h) 9747 AC_TYPE_SIZE_T 9748 AC_CHECK_TYPE(ssize_t, int) 9749 9750 headers='#ifdef HAVE_STDDEF_H 9751 #include <stddef.h> 9752 #endif 9753 #ifdef HAVE_UNISTD_H 9754 #include <unistd.h> 9755 #endif 9756 ' 9757 9758 AX_COMPILE_CHECK_SIZEOF(char) 9759 AX_COMPILE_CHECK_SIZEOF(short) 9760 AX_COMPILE_CHECK_SIZEOF(int) 9761 AX_COMPILE_CHECK_SIZEOF(long) 9762 AX_COMPILE_CHECK_SIZEOF(unsigned char *) 9763 AX_COMPILE_CHECK_SIZEOF(void *) 9764 AX_COMPILE_CHECK_SIZEOF(size_t, $headers) 9765 AX_COMPILE_CHECK_SIZEOF(ssize_t, $headers) 9766 AX_COMPILE_CHECK_SIZEOF(ptrdiff_t, $headers) 9767 AX_COMPILE_CHECK_SIZEOF(off_t, $headers) 9768 9769Source Code 9770*********** 9771 9772Download the latest version of 'ax_compile_check_sizeof.m4' 9773(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=blob_plain;f=m4/ax_compile_check_sizeof.m4) 9774or browse the macro's revision history 9775(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=history;f=m4/ax_compile_check_sizeof.m4). 9776 9777License 9778******* 9779 9780Copyright (C) 2008 Kaveh Ghazi <ghazi@caip.rutgers.edu> 9781Copyright (C) 2017 Reini Urban <rurban@cpan.org> 9782 9783This program is free software: you can redistribute it and/or modify it 9784under the terms of the GNU General Public License as published by the 9785Free Software Foundation, either version 3 of the License, or (at your 9786option) any later version. 9787 9788This program is distributed in the hope that it will be useful, but 9789WITHOUT ANY WARRANTY; without even the implied warranty of 9790MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Return the value in the variable 9826$ax_enable_compile_warnings. 9827 9828Depending on the value of -enable-compile-warnings, different compiler 9829warnings are checked to see if they work with the current compiler and, 9830if so, are appended to CFLAGS-VARIABLE and LDFLAGS-VARIABLE. This allows 9831a consistent set of baseline compiler warnings to be used across a code 9832base, irrespective of any warnings enabled locally by individual 9833developers. By standardising the warnings used by all developers of a 9834project, the project can commit to a zero-warnings policy, using -Werror 9835to prevent compilation if new warnings are introduced. This makes 9836catching bugs which are flagged by warnings a lot easier. 9837 9838By providing a consistent -enable-compile-warnings argument across all 9839projects using this macro, continuous integration systems can easily be 9840configured the same for all projects. Automated systems or build 9841systems aimed at beginners may want to pass the -disable-Werror argument 9842to unconditionally prevent warnings being fatal. 9843 9844-enable-compile-warnings can take the values: 9845 9846 * no: Base compiler warnings only; not even -Wall. 9847 * yes: The above, plus a broad range of useful warnings. 9848 * error: The above, plus -Werror so that all warnings are fatal. 9849 Use --disable-Werror to override this and disable fatal 9850 warnings. 9851 9852The set of base and enabled flags can be augmented using the 9853EXTRA-*-CFLAGS and EXTRA-*-LDFLAGS variables, which are tested and 9854appended to the output variable if -enable-compile-warnings is not "no". 9855Flags should not be disabled using these arguments, as the entire point 9856of AX_COMPILER_FLAGS is to enforce a consistent set of useful compiler 9857warnings on code, using warnings which have been chosen for low false 9858positive rates. If a compiler emits false positives for a warning, a 9859#pragma should be used in the code to disable the warning locally. See: 9860 9861 https://gcc.gnu.org/onlinedocs/gcc-4.9.2/gcc/Diagnostic-Pragmas.html#Diagnostic-Pragmas 9862 9863The EXTRA-* variables should only be used to supply extra warning flags, 9864and not general purpose compiler flags, as they are controlled by 9865configure options such as -disable-Werror. 9866 9867IS-RELEASE can be used to disable -Werror when making a release, which 9868is useful for those hairy moments when you just want to get the release 9869done as quickly as possible. Set it to "yes" to disable -Werror. By 9870default, it uses the value of $ax_is_release, so if you are using the 9871AX_IS_RELEASE macro, there is no need to pass this parameter. For 9872example: 9873 9874 AX_IS_RELEASE([git-directory]) 9875 AX_COMPILER_FLAGS() 9876 9877CFLAGS-VARIABLE defaults to WARN_CFLAGS, and LDFLAGS-VARIABLE defaults 9878to WARN_LDFLAGS. Both variables are AC_SUBST-ed by this macro, but must 9879be manually added to the CFLAGS and LDFLAGS variables for each target in 9880the code base. 9881 9882If C++ language support is enabled with AC_PROG_CXX, which must occur 9883before this macro in configure.ac, warning flags for the C++ compiler 9884are AC_SUBST-ed as WARN_CXXFLAGS, and must be manually added to the 9885CXXFLAGS variables for each target in the code base. EXTRA-*-CFLAGS can 9886be used to augment the base and enabled flags. 9887 9888Warning flags for g-ir-scanner (from GObject Introspection) are 9889AC_SUBST-ed as WARN_SCANNERFLAGS. This variable must be manually added 9890to the SCANNERFLAGS variable for each GIR target in the code base. If 9891extra g-ir-scanner flags need to be enabled, the AX_COMPILER_FLAGS_GIR 9892macro must be invoked manually. 9893 9894AX_COMPILER_FLAGS may add support for other tools in future, in addition 9895to the compiler and linker. No extra EXTRA-* variables will be added 9896for those tools, and all extra support will still use the single 9897-enable-compile-warnings configure option. For finer grained control 9898over the flags for individual tools, use AX_COMPILER_FLAGS_CFLAGS, 9899AX_COMPILER_FLAGS_LDFLAGS and AX_COMPILER_FLAGS_* for new tools. 9900 9901The UNUSED variables date from a previous version of this macro, and are 9902automatically appended to the preceding non-UNUSED variable. They 9903should be left empty in new uses of the macro. 9904 9905Source Code 9906*********** 9907 9908Download the latest version of 'ax_compiler_flags.m4' 9909(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=blob_plain;f=m4/ax_compiler_flags.m4) 9910or browse the macro's revision history 9911(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=history;f=m4/ax_compiler_flags.m4). 9912 9913License 9914******* 9915 9916Copyright (C) 2014, 2015 Philip Withnall <philip@tecnocode.co.uk> 9917Copyright (C) 2015 David King <amigadave@amigadave.com> 9918 9919Copying and distribution of this file, with or without modification, are 9920permitted in any medium without royalty provided the copyright notice 9921and this notice are preserved.

To ensure maximum portability of autoconf 10558extension macros this helper can be AC_REQUIRE'd so that 10559$ac_configure_args will always be present. 10560 10561Sadly, the traditional "exec $SHELL" of the enable_builddir macros is 10562spoiled now and must be replaced by "eval + exit $?". 10563 10564Example: 10565 10566 AC_DEFUN([AX_ENABLE_SUBDIR],[dnl 10567 AC_REQUIRE([AX_CONFIGURE_ARGS])dnl 10568 eval $SHELL $ac_configure_args || exit $? 10569 ...]) 10570 10571Source Code 10572*********** 10573 10574Download the latest version of 'ax_configure_args.m4' 10575(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=blob_plain;f=m4/ax_configure_args.m4) 10576or browse the macro's revision history 10577(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=history;f=m4/ax_configure_args.m4). 10578 10579License 10580******* 10581 10582Copyright (C) 2008 Guido U.

Many older installations will not 10844provide this file, but some will have the very same definitions in 10845<inttypes.h>. In other environments we can use the inet-types in 10846<sys/types.h> which would define the typedefs int8_t and u_int8_t 10847respectively. 10848 10849This macros will create a local "_stdint.h" or the headerfile given as 10850an argument. In many cases that file will just "#include <stdint.h>" or 10851"#include <inttypes.h>", while in other environments it will provide the 10852set of basic 'stdint's definitions/typedefs: 10853 10854 int8_t,uint8_t,int16_t,uint16_t,int32_t,uint32_t,intptr_t,uintptr_t 10855 int_least32_t.. int_fast32_t.. intmax_t 10856 10857which may or may not rely on the definitions of other files, or using 10858the AC_CHECK_SIZEOF macro to determine the actual sizeof each type. 10859 10860if your header files require the stdint-types you will want to create an 10861installable file mylib-int.h that all your other installable header may 10862include. So if you have a library package named "mylib", just use 10863 10864 AX_CREATE_STDINT_H(mylib-int.h) 10865 10866in configure.ac and go to install that very header file in Makefile.am 10867along with the other headers (mylib.h) - and the mylib-specific headers 10868can simply use "#include <mylib-int.h>" to obtain the stdint-types. 10869 10870Remember, if the system already had a valid <stdint.h>, the generated 10871file will include it directly. No need for fuzzy HAVE_STDINT_H 10872things... (oops, GCC 4.2.x has deliberately disabled its stdint.h for 10873non-c99 compilation and the c99-mode is not the default. Therefore this 10874macro will not use the compiler's stdint.h - please complain to the GCC 10875developers). 10876 10877Source Code 10878*********** 10879 10880Download the latest version of 'ax_create_stdint_h.m4' 10881(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=blob_plain;f=m4/ax_create_stdint_h.m4) 10882or browse the macro's revision history 10883(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=history;f=m4/ax_create_stdint_h.m4). 10884 10885License 10886******* 10887 10888Copyright (C) 2008 Guido U.

This means you MUST have the 15312shell variable EMACS set to a valid Emacs executable prior to the first 15313call to any of the AX_ELISP_CHECK et al macros. Those work by saving 15314their results to the file defined by calling AX_ELISP_CONFIG_FILE so you 15315MUST call that prior, too. For example: 15316 15317 dnl Arrange to save config answers in $top_builddir/lisp/config.el. 15318 AX_ELISP_CONFIG_FILE([lisp/config.el]) 15319 15320 dnl Set shell variable EMACS and AC_SUBST it, too. 15321 dnl (NB: This is a separate Autoconf Archive macro.) 15322 AX_PROG_EMACS 15323 15324In the following detailed descriptions, SYMBOL stands for an Emacs Lisp 15325symbol, which may contain hyphens, e.g., 'define-error' or 'org-src'. 15326Likewise, FEATURE is an Emacs Lisp symbol (naming a feature). BODY and 15327SUCCESS-EXPR are Emacs Lisp forms, zero or more for BODY and exactly one 15328for SUCCESS-EXPR. In these forms you must take care to avoid apostrophe 15329(U+27). Instead of 'foo, write (quote foo). 15330 15331* AX_ELISP_CONFIG_FILE(FILENAME) 15332 15333This arranges for future AX_ELISP_CHECK (et al) calls to save their 15334results in FILENAME. May be called multiple times. FILENAME should be 15335relative to the top build dir. 15336 15337* AX_ELISP_CHECK(SYMBOL,DESCRIPTION,BODY,SUCCESS-EXPR) 15338 15339This is the general macro that the other AX_ELISP_CHECK* macros use. It 15340constructs a short Emacs Lisp file comprising BODY and evaluates it via 15341$EMACS -batch -Q. The exit value of this script depends on the result of 15342evaluating SUCCESS-EXPR: non-nil is success and nil is failure. On 15343success, append SYMBOL on a line of its own to the config file. This 15344macro uses AC_CACHE_CHECK and passes DESCRIPTION to it. 15345 15346* AX_ELISP_CHECK_FEATURE(FEATURE) 15347 15348This checks if (require (quote FEATURE)) is successful. If so, add 15349featurep-FEATURE to the config file (NB the "featurep-" prefix). 15350 15351* AX_ELISP_CHECK_FBOUNDP(SYMBOL,[FEATURE [...]]) 15352 15353This checks if (fboundp (quote SYMBOL)) is successful. If so, append 15354SYMBOL to the config file. Optional 2nd arg is a space-separated list 15355of features to require prior to the fboundp check. 15356 15357* AX_ELISP_CHECK_BOUNDP(SYMBOL,[FEATURE [...]]) 15358 15359This checks if (boundp (quote SYMBOL)) is successful. If so, append 15360SYMBOL to the config file. Optional 2nd arg is a space-separated list 15361of features to require prior to the boundp check. 15362 15363Source Code 15364*********** 15365 15366Download the latest version of 'ax_elisp.m4' 15367(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=blob_plain;f=m4/ax_elisp.m4) 15368or browse the macro's revision history 15369(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=history;f=m4/ax_elisp.m4). 15370 15371License 15372******* 15373 15374Copyright (C) 2016-2017 Thien-Thi Nguyen 15375 15376This program is free software; you can redistribute it and/or modify it 15377under the terms of the GNU General Public License as published by the 15378Free Software Foundation; either version 3 of the License, or (at your 15379option) any later version. 15380 15381This program is distributed in the hope that it will be useful, but 15382WITHOUT ANY WARRANTY; without even the implied warranty of 15383MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

We provide an option -disable-builddir to suppress the move into 15419a separate builddir. 15420 15421Defaults: 15422 15423 $1 = $host (overridden with $HOST) 15424 $2 = Makefile.mk 15425 $3 = -all 15426 15427This macro must be called before AM_INIT_AUTOMAKE. It creates a default 15428toplevel srcdir Makefile from the information found in the created 15429toplevel builddir Makefile. It just copies the variables and 15430rule-targets, each extended with a default rule-execution that recurses 15431into the build directory of the current "HOST". You can override the 15432auto-detection through 'config.guess' and build-time of course, as in 15433 15434 make HOST=i386-mingw-cross 15435 15436which can of course set at configure time as well using 15437 15438 configure --host=i386-mingw-cross 15439 15440After the default has been created, additional rules can be appended 15441that will not just recurse into the subdirectories and only ever exist 15442in the srcdir toplevel makefile - these parts are read from the $2 = 15443Makefile.mk file 15444 15445The automatic rules are usually scanning the toplevel Makefile for lines 15446like '#### $host |$builddir' to recognize the place where to recurse 15447into. Usually, the last one is the only one used. However, almost all 15448targets have an additional "*-all" rule which makes the script to 15449recurse into _all_ variants of the current HOST (!!) setting. The 15450"-all" suffix can be overridden for the macro as well. 15451 15452a special rule is only given for things like "dist" that will copy the 15453tarball from the builddir to the sourcedir (or $(PUB)) for reason of 15454convenience. 15455 15456Source Code 15457*********** 15458 15459Download the latest version of 'ax_enable_builddir.m4' 15460(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=blob_plain;f=m4/ax_enable_builddir.m4) 15461or browse the macro's revision history 15462(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=history;f=m4/ax_enable_builddir.m4). 15463 15464License 15465******* 15466 15467Copyright (C) 2009 Guido U.

It has been observed that it was done wrong 15559over and over again, so this is a bit more safe to do. 15560 15561remember - setting exec_prefix='${prefix}' needs you interpolate 15562directories multiple times, it is not sufficient to just say 15563MYVAR="${datadir}/putter" but you do have to run 'eval' a few times, 15564sth. like MYVAR='eval "echo \"$MYVAR\""' done at least two times. 15565 15566The implementation of this macro simply picks up the lines that would be 15567run at the start of AC_OUTPUT anyway to set the prefix/exec_prefix 15568defaults.

After calling AX_EXTEND_SRCDIR, 15765$srcdir will be set to "../../i3-4.12". 15766 15767The result of extending $srcdir is that filenames (e.g. in the output 15768of the "backtrace" gdb command) will include one more path component of 15769the absolute source path. The additional path component makes it easy 15770for users to recognize which files belong to the PACKAGE, and - provided 15771a dist tarball was unpacked - which version of PACKAGE was used. 15772 15773As an example, in "backtrace", you will see: 15774 15775 #0 main (argc=1, argv=0x7fffffff1fc8) at ../../i3-4.12/src/main.c:187 15776 15777instead of: 15778 15779 #0 main (argc=1, argv=0x7fffffff1fc8) at ../src/main.c:187 15780 15781In case your code uses the __FILE__ preprocessor directive to refer to 15782the filename of the current source file (e.g. in debug messages), using 15783the extended path might be undesirable. For this purpose, 15784AX_EXTEND_SRCDIR defines the output variable AX_EXTEND_SRCDIR_CPPFLAGS, 15785which can be added to AM_CPPFLAGS in Makefile.am in order to define the 15786preprocessor directive STRIPPED__FILE__. As an example, when compiling 15787the file "../../i3-4.12/src/main.c", STRIPPED__FILE__ evaluates to 15788"main.c". 15789 15790There are some caveats: When $srcdir is "." (i.e. when ./configure was 15791called instead of ../configure in a separate build directory), 15792AX_EXTEND_SRCDIR will still extend $srcdir, but the intended effect will 15793not be achieved because of the way automake specifies file paths: 15794automake defines COMPILE to use "'test -f '$source' || echo 15795'\$(srcdir)/''$source" in order to prefer files in the current directory 15796over specifying $srcdir explicitly. 15797 15798The AX_EXTEND_SRCDIR author is not aware of any way to influence this 15799automake behavior. Patches very welcome. 15800 15801To work around this issue, you can use AX_ENABLE_BUILDDIR i.e. by 15802adding the following code to configure.ac: 15803 15804 AX_ENABLE_BUILDDIR 15805 dnl ... 15806 AX_EXTEND_SRCDIR 15807 15808Then also add this bit to Makefile.am (if you wish to use 15809STRIPPED__FILE__ in your code): 15810 15811 AM_CPPFLAGS = @AX_EXTEND_SRCDIR_CPPFLAGS@ 15812 15813Source Code 15814*********** 15815 15816Download the latest version of 'ax_extend_srcdir.m4' 15817(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=blob_plain;f=m4/ax_extend_srcdir.m4) 15818or browse the macro's revision history 15819(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=history;f=m4/ax_extend_srcdir.m4). 15820 15821License 15822******* 15823 15824Copyright (C) 2016 Michael Stapelberg <michael@i3wm.org> 15825 15826Copying and distribution of this file, with or without modification, are 15827permitted in any medium without royalty provided the copyright notice 15828and this notice are preserved.

The macro also automatically updates the FCFLAGS, LDFLAGS 16113and LIBS variables in addition to providing the F90_HEADER_xxx, 16114F90_MODULE_xxx, F90_LDFLAGS_xxx and F90_LIBS_xxx output variables. 16115 16116Example: suppose you have /home/nostradamus/esoteric/lib/libalchemy.a 16117and /home/nostradamus/esoteric/mod/alchemy.mod which provides a function 16118transmute_into_gold, you can use the following in you configure.ac: 16119 16120 AX_F90_MODULE_EXTENSION 16121 if test x$ax_cv_f90_modext = xunknown ; then 16122 AC_MSG_ERROR([unable to find f90 modules extension]) 16123 fi 16124 AX_F90_LIBRARY_SETUP(alchemy,[],alchemy.$ax_cv_f90_modext,libalchemy*,[ 16125 use alchemy 16126 call transmute_into_gold('lead') 16127 ]) 16128 16129and the user could configure your package using a command like this: 16130 16131 ./configure --with-alchemy=$HOME/esoteric 16132 16133Source Code 16134*********** 16135 16136Download the latest version of 'ax_f90_library_setup.m4' 16137(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=blob_plain;f=m4/ax_f90_library_setup.m4) 16138or browse the macro's revision history 16139(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=history;f=m4/ax_f90_library_setup.m4). 16140 16141License 16142******* 16143 16144Copyright (C) 2009 Luc Maisonobe <luc@spaceroots.org> 16145 16146Copying and distribution of this file, with or without modification, are 16147permitted in any medium without royalty provided the copyright notice 16148and this notice are preserved.

MODULE-REGEXP is a regular expression (used by 16167find) matched by the filename of the module. FUNCTION-BODY is the body 16168of a function (including the 'use' statement and the call to a function 16169defined by the module) SEARCH-PATH is a colon-separated list of 16170directories that will be recursively searched for modules files. If 16171empty, the search path will be composed of $prefix, $ac_default_prefix, 16172and all directories exactly one level *above* the directories in 16173$LD_LIBRARY_PATH (the rationale is that when libraries are put in 16174/some/path/lib, the modules are often put in a directory like 16175/some/path/include or /some/path/mod or something similar). An output 16176variable named F90_MODULE_xxx will be set up with the proper flag for 16177substitution in Makefiles (xxx is built from the first argument, with 16178autoconf traditional escapes). 16179 16180Source Code 16181*********** 16182 16183Download the latest version of 'ax_f90_module.m4' 16184(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=blob_plain;f=m4/ax_f90_module.m4) 16185or browse the macro's revision history 16186(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=history;f=m4/ax_f90_module.m4). 16187 16188License 16189******* 16190 16191Copyright (C) 2009 Luc Maisonobe <luc@spaceroots.org> 16192 16193Copying and distribution of this file, with or without modification, are 16194permitted in any medium without royalty provided the copyright notice 16195and this notice are preserved.

If 16967found, the cache variable $ax_cv_gcc_archflag is set to this flag and 16968ACTION-SUCCESS is executed; otherwise $ax_cv_gcc_archflag is set to 16969"unknown" and ACTION-FAILURE is executed. The default ACTION-SUCCESS is 16970to add $ax_cv_gcc_archflag to the end of $CFLAGS. 16971 16972PORTABLE? should be either [yes] (default) or [no]. In the former case, 16973the flag is set to -mtune (or equivalent) so that the architecture is 16974only used for tuning, but the instruction set used is still portable. 16975In the latter case, the flag is set to -march (or equivalent) so that 16976architecture-specific instructions are enabled. 16977 16978The user can specify -with-gcc-arch=<arch> in order to override the 16979macro's choice of architecture, or -without-gcc-arch to disable this. 16980 16981When cross-compiling, or if $CC is not gcc, then ACTION-FAILURE is 16982called unless the user specified -with-gcc-arch manually. 16983 16984Requires macros: AX_CHECK_COMPILE_FLAG, AX_GCC_X86_CPUID 16985 16986(The main emphasis here is on recent CPUs, on the principle that doing 16987high-performance computing on old hardware is uncommon.) 16988 16989Source Code 16990*********** 16991 16992Download the latest version of 'ax_gcc_archflag.m4' 16993(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=blob_plain;f=m4/ax_gcc_archflag.m4) 16994or browse the macro's revision history 16995(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=history;f=m4/ax_gcc_archflag.m4). 16996 16997License 16998******* 16999 17000Copyright (C) 2008 Steven G.

The instruction set 17658that can be tested are "mmx, popcnt, sse, sse2, sse3, sse4.1, sse4.2, 17659sse4a, avx, avx2, avx512f, fma, fma4, bmi, bmi2". If the instruction 17660set is supported by the host cpu, the C preprocessor macro 17661HAVE_XXX_INSTRUCTIONS is set to 1. The XXX is up-cased instruction case 17662with dot replaced by underscore. For example, the test for "sse4.2" 17663would export HAVE_SSE4_2_INSTRUCTIONS=1. This macro requires gcc 17664extended builtin function "__builtin_cpu_init" and 17665"__builtin_cpu_supports" to detect the cpu features. It will error out 17666if the compiler doesn't has these builtins. 17667 17668If the test for the instruction set succeeded, the hook ACTION-IF-FOUND 17669would run. Otherwise the hook ACTION-IF-NOT-FOUND would run if 17670specified. 17671 17672See also AX_CHECK_X86_FEATURES, which checks all the possible 17673instruction set and export the corresponding CFLAGS. 17674 17675Source Code 17676*********** 17677 17678Download the latest version of 'ax_gcc_x86_cpu_supports.m4' 17679(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=blob_plain;f=m4/ax_gcc_x86_cpu_supports.m4) 17680or browse the macro's revision history 17681(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=history;f=m4/ax_gcc_x86_cpu_supports.m4). 17682 17683License 17684******* 17685 17686Copyright (C) 2016 Felix Chern <idryman@gmail.com> 17687 17688This program is free software; you can redistribute it and/or modify it 17689under the terms of the GNU General Public License as published by the 17690Free Software Foundation; either version 2 of the License, or (at your 17691option) any later version. 17692 17693This program is distributed in the hope that it will be useful, but 17694WITHOUT ANY WARRANTY; without even the implied warranty of 17695MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

But the only help given the 17883developer in setting up the framework is the AC_CONFIG_TESTDIR() 17884command, which leaves several additional steps up to the developer 17885copying examples from the manual: 17886 17887 * generating the "package.m4" file used in generating the "testsuite" 17888 * generating the "testsuite" executable by calling autom4te 17889 * adding Makefile rules to keep both "package.m4" and "testsuite" 17890 current 17891 * figuring out how to do all the above if the Makefile does not reside 17892 in the testdir 17893 17894This command takes care of all of the above. It is designed to be 17895called multiple times for different testdir directories, to have 17896multiple testsuites scripts per directory and to handle the optional 17897"package.m4" and "atlocal" (re)generation. 17898 17899The various actions taken by this command happen in different phases of 17900the build process: 17901 17902 1) During the autoconf execution, generate the testsuites and any 17903 "package.m4" files. So these are already available before configure 17904 ran. The reasoning for deviating from the examples in [1] is that 17905 these files are distributed and must be placed in the srcdir: it 17906 seems cleaner to not generate anything in srcdir during any of the 17907 later phases. 17908 2) During the config.status execution (following the configure 17909 execution), generate "atconfig" and any "atlocal" files in the 17910 buildir. The "atconfig" generation is handled by calling 17911 AC_CONFIG_TESTDIR() so the developer does not have to do so 17912 themselves. 17913 3) During the execution of make, several additional rules and file 17914 lists are made available via AC_SUBST(). The rules are intended 17915 to be called where appropriate (e.g. make check can depend on 17916 check-autotest) and the file lists are intended to be added 17917 to the appropriate lists (i.e. to DISTCLEANFILES and EXTRA_DIST). 17918 17919Description of AX_GNU_AUTOTEST() arguments: 17920 17921 * testdir: directory-name containing the testsuites. AX_GNU_AUTOTEST() 17922 must be called exactly once for each directory containing testsuites. 17923 If empty, defaults to "tests". 17924 * testsuites: space-separated list of words, where each word is the 17925 name of a test suite script optionally followed by a colon and the 17926 name of the scripts source file. If the source file is not given, 17927 it defaults to the script name suffixed by ".at". So these words 17928 are all equivalent: "foo", "foo:" and "foo:foo.at". If the argument 17929 is empty, it defaults to "testsuite". The script filenames must not 17930 contain any path, but that is allowed for the source filenames. 17931 * atlocal-sources: space- or colon-separated list of filenames, which 17932 are registered with AC_CONFIG_FILES() as the sources of atlocal. 17933 If empty, no atlocal file is generated. 17934 * gen-package: boolean ("yes" or "no") indicating whether "package.m4" 17935 should be generated. If empty, defaults to "yes". 17936 * force: boolean ("yes" or "no") whether to treat errors in arguments 17937 as errors and abort (for "no") or whether to ignore any such errors 17938 (for "yes"). If empty, defaults to "no". 17939 17940All filenames above must be relative. The testdir name is interpreted 17941relative to top_srcdir. All other names are interpreted relative to the 17942testdir. The boolean values are interpreted as "yes" for any non-empty 17943value except "0", "n", "no" and their mixed-case variants. 17944 17945Description of Makefile.am / Makefile.in substitutions: 17946 17947 * AX_GNU_AUTOTEST_RULES: the make rules provided here. Substitute this 17948 in a separate line. 17949 * AX_GNU_AUTOTEST_DCLEAN: the list of files to be added to 17950 DISTCLEANFILES. 17951 * AX_GNU_AUTOTEST_DIST: the list of files to be added to EXTRA_DIST. 17952 * AX_GNU_AUTOTEST_DEFAULT: includes all other substitutions and uses 17953 them in a "default" way. 17954 17955All must be used as a substitution (@...@) instead of as a variable 17956($(...) or ${...}). These substitutions are generated multiple times, 17957once for each directory where an affected Makefile may be located. All 17958substitutions start with the base as given above but may have suffixes 17959for the directories. Assuming this example in configure.ac: 17960 17961 AX_GNU_AUTOTEST([foo/bar]) 17962 AX_GNU_AUTOTEST([baz]) 17963 17964Then the following substitutions are available (where <base> stands for 17965one of the above prefixes): 17966 17967 * <base> : for use in top_srcdir/Makefile 17968 * <base>_foo : for use in top_srcdir/foo/Makefile 17969 * <base>_foo_bar : for use in top_srcdir/foo/bar/Makefile 17970 * <base>_baz : for use in top_srcdir/baz/Makefile 17971 17972The <base> substitutions cover both foo/bar and baz, so none of the 17973other substitutions should be used. Indeed, no Makefiles are needed in 17974the other directories. But if sub-directory Makefiles are used, then 17975both <base>_baz and either of <base>_foo or <base>_foo_bar must be used 17976in their respective Makefiles. 17977 17978Description of Makefile targets defined by AX_GNU_AUTOTEST_RULES*: 17979 17980 * check-autotest: The equivalent of check. 17981 * installcheck-autotest: The equivalent of installcheck. 17982 * clean-autotest: The equivalent of clean. 17983 17984The developer can either define the above targets as dependencies of 17985their appropriate equivalent rule or of their *-local equivalent rule 17986for automake or they can define a rule with a sub-make call as they 17987wish. 17988 17989All rules are dependent on like-named rules for each sub-directory and 17990for each testsuite. Only the testsuite rules actually do any work, the 17991rest are just collectors and convenience names. Assuming this example 17992in configure.ac: 17993 17994 AX_GNU_AUTOTEST([foo], [testsuite bar]) 17995 AX_GNU_AUTOTEST([baz]) 17996 17997Then AX_GNU_AUTOTEST_RULES defines these check rules (likewise for 17998installcheck and clean): 17999 18000 check-autotest: check-autotest-foo check-autotest-baz 18001 check-autotest-foo: check-autotest-foo-testsuite check-autotest-foo-bar 18002 check-autotest-baz: check-autotest-baz-testsuite 18003 check-autotest-foo-testsuite # Executes foo/testsuite -C foo 18004 check-autotest-foo-bar # Executes foo/bar -C foo 18005 check-autotest-baz-testsuite # Executes baz/testsuite -C baz 18006 18007And AX_GNU_AUTOTEST_RULES_baz defines these check rules: 18008 18009 check-autotest: check-autotest-testsuite 18010 check-autotest-testsuite # Executes testsuite (which is baz/testsuite) 18011 18012Note how the rule names only contain the directory and testsuite paths 18013relative to the Makefile location. Also note how each testsuite is 18014executed in its respective testdir. 18015 18016In addition to the above, AX_GNU_AUTOTEST_RULES* also contains the rules 18017to keep the testsuites, "package.m4" and "atconfig" updated. The 18018matching rules to keep "atlocal" updated are generated by automake if 18019that is used or are the responsibility of the developer. 18020 18021All testsuite executions (except for clean) use variables 18022AX_GNU_AUTOTEST_FLAGS, AX_GNU_AUTOTEST_CHECK_FLAGS, 18023AX_GNU_AUTOTEST_INSTALLCHECK_FLAGS and more path-and-script-specific 18024variants for additional command line options. These variables can be 18025defined by the developer to pass options to the testsuite. In the 18026example above, the rule check-autotest-foo-bar would look like this: 18027 18028 check-autotest-foo-bar: 18029 foo/bar -C foo $(AX_GNU_AUTOTEST_FLAGS) \ 18030 $(AX_GNU_AUTOTEST_CHECK_FLAGS) \ 18031 $(AX_GNU_AUTOTEST_FLAGS_foo) \ 18032 $(AX_GNU_AUTOTEST_CHECK_FLAGS_foo) \ 18033 $(AX_GNU_AUTOTEST_FLAGS_foo_bar) \ 18034 $(AX_GNU_AUTOTEST_CHECK_FLAGS_foo_bar) 18035 18036Description of Makefile file lists: 18037 18038These lists are intended to be added to DISTCLEANFILES and EXTRA_DIST. 18039The *_DCLEAN list contains all "atconfig" files and the *_DIST list 18040contains all testsuites and "package.m4" files. The lists are again 18041generated per directory: so AX_GNU_AUTOTEST_DCLEAN contains all 18042"atconfig" files while e.g. AX_GNU_AUTOTEST_DIST_foo contains only 18043files below the "foo" directory. These file lists are prevented from 18044becoming Makefile variables by calling AM_SUBST_NOTMAKE(): that way, 18045only the single version used by the Makefile is substituted, not all 18046lists for all other paths as well. So use either like this: 18047 18048 DISTCLEANFILES = @AX_GNU_AUTOTEST_DCLEAN@ 18049 EXTRA_DIST = @AX_GNU_AUTOTEST_DIST_foo@ 18050 18051Or like this: 18052 18053 AX_GNU_AUTOTEST_DCLEAN_foo = @AX_GNU_AUTOTEST_DCLEAN_foo@ 18054 AX_GNU_AUTOTEST_DIST_foo = @AX_GNU_AUTOTEST_DIST_foo@ 18055 DISTCLEANFILES = ${AX_GNU_AUTOTEST_DCLEAN_foo} 18056 EXTRA_DIST = ${AX_GNU_AUTOTEST_DIST_foo} 18057 18058Description of shorthand default Makefile contents defined by 18059AX_GNU_AUTOTEST_DEFAULT*: 18060 18061This shorthand defines the appropriate rules, adds the file lists to the 18062proper variables and makes the new targets dependencies of the standard 18063"check", "installcheck" and "clean" targets. AX_GNU_AUTOTEST_DEFAULT is 18064for example equivalent to: 18065 18066 @AX_GNU_AUTOTEST_RULES@ 18067 check: check-autotest 18068 installcheck: installcheck-autotest 18069 clean: clean-autotest 18070 distclean: distclean-autotest 18071 distclean-autotest: clean-autotest 18072 -rm -f @AX_GNU_AUTOTEST_DCLEAN@ 18073 .PHONY: distclean-autotest 18074 EXTRA_DIST += @AX_GNU_AUTOTEST_DIST@ 18075 18076Note that this is copied verbatim into the Makefile (after expansion of 18077the contained @...@ substitutions): it does not shadow the default 18078targets as would happen if the same lines were written in a Makefile.am 18079file. And also note the use of the += operator: this will not be 18080compatible with all versions of Make.

This 18182check is somewhat unreliable if <linux/version.h> doesn't match the 18183running kernel, but it is necessary regardless, because glibc comes with 18184stubs for the epoll_create(), epoll_wait(), etc. that allow programs to 18185compile and link even if the kernel is too old; the problem would then 18186be detected only at runtime. 18187 18188Linux kernel version 2.6.19 adds the epoll_pwait() call in addition to 18189epoll_wait().

When this macro completes, a list of directories is left in 18637the variable JNI_INCLUDE_DIRS. 18638 18639Example usage follows: 18640 18641 AX_JNI_INCLUDE_DIR 18642 18643 for JNI_INCLUDE_DIR in $JNI_INCLUDE_DIRS 18644 do 18645 CPPFLAGS="$CPPFLAGS -I$JNI_INCLUDE_DIR" 18646 done 18647 18648If you want to force a specific compiler: 18649 18650- at the configure.in level, set JAVAC=yourcompiler before calling 18651AX_JNI_INCLUDE_DIR 18652 18653- at the configure level, setenv JAVAC 18654 18655This macro depends on AC_CANONICAL_HOST which requires that config.guess 18656and config.sub be distributed along with the source code. See autoconf 18657manual for details. 18658 18659Note: This macro can work with the autoconf M4 macros for Java programs. 18660This particular macro is not part of the original set of macros. 18661 18662Source Code 18663*********** 18664 18665Download the latest version of 'ax_jni_include_dir.m4' 18666(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=blob_plain;f=m4/ax_jni_include_dir.m4) 18667or browse the macro's revision history 18668(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=history;f=m4/ax_jni_include_dir.m4). 18669 18670License 18671******* 18672 18673Copyright (C) 2008 Don Anderson <dda@sleepycat.com> 18674 18675Copying and distribution of this file, with or without modification, are 18676permitted in any medium without royalty provided the copyright notice 18677and this notice are preserved.

On success, it sets the 18696LAPACK_LIBS output variable to hold the requisite library linkages. 18697 18698To link with LAPACK, you should link with: 18699 18700 $LAPACK_LIBS $BLAS_LIBS $LIBS $FLIBS 18701 18702in that order. BLAS_LIBS is the output variable of the AX_BLAS macro, 18703called automatically. FLIBS is the output variable of the 18704AC_F77_LIBRARY_LDFLAGS macro (called if necessary by AX_BLAS), and is 18705sometimes necessary in order to link with F77 libraries. Users will 18706also need to use AC_F77_DUMMY_MAIN (see the autoconf manual), for the 18707same reason. 18708 18709The user may also use -with-lapack=<lib> in order to use some specific 18710LAPACK library <lib>. In order to link successfully, however, be aware 18711that you will probably need to use the same Fortran compiler (which can 18712be set via the F77 env. var.) as was used to compile the LAPACK and 18713BLAS libraries. 18714 18715ACTION-IF-FOUND is a list of shell commands to run if a LAPACK library 18716is found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it 18717is not found. If ACTION-IF-FOUND is not specified, the default action 18718will define HAVE_LAPACK. 18719 18720Source Code 18721*********** 18722 18723Download the latest version of 'ax_lapack.m4' 18724(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=blob_plain;f=m4/ax_lapack.m4) 18725or browse the macro's revision history 18726(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=history;f=m4/ax_lapack.m4). 18727 18728License 18729******* 18730 18731Copyright (C) 2009 Steven G.

If found, defines 20011'HAVE_LIBREADLINE'. If the found library has the 'add_history' function, 20012sets also 'HAVE_READLINE_HISTORY'. Also checks for the locations of the 20013necessary include files and sets 'HAVE_READLINE_H' or 20014'HAVE_READLINE_READLINE_H' and 'HAVE_READLINE_HISTORY_H' or 20015'HAVE_HISTORY_H' if the corresponding include files exists. 20016 20017The libraries that may be readline compatible are 'libedit', 20018'libeditline' and 'libreadline'. Sometimes we need to link a termcap 20019library for readline to work, this macro tests these cases too by trying 20020to link with 'libtermcap', 'libcurses' or 'libncurses' before giving up. 20021 20022Here is an example of how to use the information provided by this macro 20023to perform the necessary includes or declarations in a C file: 20024 20025 #ifdef HAVE_LIBREADLINE 20026 # if defined(HAVE_READLINE_READLINE_H) 20027 # include <readline/readline.h> 20028 # elif defined(HAVE_READLINE_H) 20029 # include <readline.h> 20030 # else /* !defined(HAVE_READLINE_H) */ 20031 extern char *readline (); 20032 # endif /* !defined(HAVE_READLINE_H) */ 20033 char *cmdline = NULL; 20034 #else /* !defined(HAVE_READLINE_READLINE_H) */ 20035 /* no readline */ 20036 #endif /* HAVE_LIBREADLINE */ 20037 20038 #ifdef HAVE_READLINE_HISTORY 20039 # if defined(HAVE_READLINE_HISTORY_H) 20040 # include <readline/history.h> 20041 # elif defined(HAVE_HISTORY_H) 20042 # include <history.h> 20043 # else /* !defined(HAVE_HISTORY_H) */ 20044 extern void add_history (); 20045 extern int write_history (); 20046 extern int read_history (); 20047 # endif /* defined(HAVE_READLINE_HISTORY_H) */ 20048 /* no history */ 20049 #endif /* HAVE_READLINE_HISTORY */ 20050 20051Source Code 20052*********** 20053 20054Download the latest version of 'ax_lib_readline.m4' 20055(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=blob_plain;f=m4/ax_lib_readline.m4) 20056or browse the macro's revision history 20057(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=history;f=m4/ax_lib_readline.m4). 20058 20059License 20060******* 20061 20062Copyright (C) 2008 Ville Laurikari <vl@iki.fi> 20063 20064Copying and distribution of this file, with or without modification, are 20065permitted in any medium without royalty provided the copyright notice 20066and this notice are preserved.

If nothing was 20084specified when calling configure, it searches first in /usr/local and 20085then tries with ld's default library search path. If the 20086-with-samtools=DIR is specified, it will try to find it in 20087DIR/include/bam/sam.h and DIR/lib/libbam.a. As a final try it will look 20088in DIR/sam.h and DIR/libbam.a as the samtools library does not contain 20089an install rule. 20090 20091If -without-samtools is specified, the library is not searched at all. 20092 20093If either the header file (sam.h) or the library (libbam) is not found, 20094the configuration exits on error, asking for a valid samtools 20095installation directory or -without-samtools. 20096 20097The macro defines the symbol HAVE_SAMTOOLS if the library is found. You 20098should use autoheader to include a definition for this symbol in a 20099config.h file. Sample usage in a C/C++ source is as follows: 20100 20101 #ifdef HAVE_SAMTOOLS 20102 #include <sam.h> 20103 #endif /* HAVE_SAMTOOLS */ 20104 20105The following output variables are set with AC_SUBST: 20106 20107 SAMTOOLS_CPPFLAGS 20108 SAMTOOLS_LDFLAGS 20109 SAMTOOLS_LIBS 20110 20111You can use them like this in Makefile.am: 20112 20113 AM_CPPFLAGS = $(SAMTOOLS_CPPFLAGS) 20114 AM_LDFLAGS = $(SAMTOOLS_LDFLAGS) 20115 program_LDADD = $(SAMTOOLS_LIBS) 20116 20117Source Code 20118*********** 20119 20120Download the latest version of 'ax_lib_samtools.m4' 20121(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=blob_plain;f=m4/ax_lib_samtools.m4) 20122or browse the macro's revision history 20123(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=history;f=m4/ax_lib_samtools.m4). 20124 20125License 20126******* 20127 20128Copyright (C) 2013 Timothy Brown <tbrown@freeshell.org> 20129 20130This program is free software; you can redistribute it and/or modify it 20131under the terms of the GNU General Public License as published by the 20132Free Software Foundation; either version 3 of the License, or (at your 20133option) any later version. 20134 20135This program is distributed in the hope that it will be useful, but 20136WITHOUT ANY WARRANTY; without even the implied warranty of 20137MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

If nothing was 20265specified when calling configure, it searches first in /usr/local and 20266then tries with ld's default library search path. If the 20267-with-tabix=DIR is specified, it will try to find it in 20268DIR/include/tabix/tabix.h and DIR/lib/libtabix.a. As a final try it 20269will look in DIR/tabix.h and DIR/libtabix.a as the tabix library does 20270not contain an install rule. 20271 20272If -without-tabix is specified, the library is not searched at all. 20273 20274If either the header file (tabix.h) or the library (libtabix) is not 20275found, the configuration exits on error, asking for a valid tabix 20276installation directory or -without-tabix. 20277 20278The macro defines the symbol HAVE_TABIX if the library is found. You 20279should use autoheader to include a definition for this symbol in a 20280config.h file. Sample usage in a C/C++ source is as follows: 20281 20282 #ifdef HAVE_TABIX 20283 #include <tabix.h> 20284 #endif /* HAVE_TABIX */ 20285 20286The following output variables are set with AC_SUBST: 20287 20288 TABIX_CPPFLAGS 20289 TABIX_LDFLAGS 20290 TABIX_LIBS 20291 20292You can use them like this in Makefile.am: 20293 20294 AM_CPPFLAGS = $(TABIX_CPPFLAGS) 20295 AM_LDFLAGS = $(TABIX_LDFLAGS) 20296 program_LDADD = $(TABIX_LIBS) 20297 20298Source Code 20299*********** 20300 20301Download the latest version of 'ax_lib_tabix.m4' 20302(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=blob_plain;f=m4/ax_lib_tabix.m4) 20303or browse the macro's revision history 20304(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=history;f=m4/ax_lib_tabix.m4). 20305 20306License 20307******* 20308 20309Copyright (C) 2013 Timothy Brown <tbrown@freeshell.org> 20310 20311This program is free software; you can redistribute it and/or modify it 20312under the terms of the GNU General Public License as published by the 20313Free Software Foundation; either version 3 of the License, or (at your 20314option) any later version. 20315 20316This program is distributed in the hope that it will be useful, but 20317WITHOUT ANY WARRANTY; without even the implied warranty of 20318MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Set up important Lua paths, such as the directories in 20864which to install scripts and modules (shared libraries). 20865 20866Also detect Lua headers and libraries. The Lua version contained in the 20867header is checked to match the Lua interpreter version exactly. When 20868searching for Lua libraries, the version number is used as a suffix. 20869This is done with the goal of supporting multiple Lua installs (5.1, 208705.2, and 5.3 side-by-side). 20871 20872A note on compatibility with previous versions: This file has been 20873mostly rewritten for serial 18. Most developers should be able to use 20874these macros without needing to modify configure.ac. Care has been 20875taken to preserve each macro's behavior, but there are some differences: 20876 208771) AX_WITH_LUA is deprecated; it now expands to the exact same thing as 20878AX_PROG_LUA with no arguments. 20879 208802) AX_LUA_HEADERS now checks that the version number defined in lua.h 20881matches the interpreter version. AX_LUA_HEADERS_VERSION is therefore 20882unnecessary, so it is deprecated and does not expand to anything. 20883 208843) The configure flag -with-lua-suffix no longer exists; the user should 20885instead specify the LUA precious variable on the command line. See the 20886AX_PROG_LUA description for details. 20887 20888Please read the macro descriptions below for more information. 20889 20890This file was inspired by Andrew Dalke's and James Henstridge's 20891python.m4 and Tom Payne's, Matthieu Moy's, and Reuben Thomas's ax_lua.m4 20892(serial 17). Basically, this file is a mash-up of those two files. I 20893like to think it combines the best of the two! 20894 20895AX_PROG_LUA: Search for the Lua interpreter, and set up important Lua 20896paths. Adds precious variable LUA, which may contain the path of the 20897Lua interpreter. If LUA is blank, the user's path is searched for an 20898suitable interpreter. 20899 20900If MINIMUM-VERSION is supplied, then only Lua interpreters with a 20901version number greater or equal to MINIMUM-VERSION will be accepted. If 20902TOO-BIG-VERSION is also supplied, then only Lua interpreters with a 20903version number greater or equal to MINIMUM-VERSION and less than 20904TOO-BIG-VERSION will be accepted. 20905 20906The Lua version number, LUA_VERSION, is found from the interpreter, and 20907substituted. LUA_PLATFORM is also found, but not currently supported 20908(no standard representation). 20909 20910Finally, the macro finds four paths: 20911 20912 luadir Directory to install Lua scripts. 20913 pkgluadir $luadir/$PACKAGE 20914 luaexecdir Directory to install Lua modules. 20915 pkgluaexecdir $luaexecdir/$PACKAGE 20916 20917These paths are found based on $prefix, $exec_prefix, Lua's 20918package.path, and package.cpath. The first path of package.path 20919beginning with $prefix is selected as luadir. The first path of 20920package.cpath beginning with $exec_prefix is used as luaexecdir. This 20921should work on all reasonable Lua installations. If a path cannot be 20922determined, a default path is used. Of course, the user can override 20923these later when invoking make. 20924 20925 luadir Default: $prefix/share/lua/$LUA_VERSION 20926 luaexecdir Default: $exec_prefix/lib/lua/$LUA_VERSION 20927 20928These directories can be used by Automake as install destinations. The 20929variable name minus 'dir' needs to be used as a prefix to the 20930appropriate Automake primary, e.g. lua_SCRIPS or luaexec_LIBRARIES. 20931 20932If an acceptable Lua interpreter is found, then ACTION-IF-FOUND is 20933performed, otherwise ACTION-IF-NOT-FOUND is preformed. If 20934ACTION-IF-NOT- FOUND is blank, then it will default to printing an 20935error. To prevent the default behavior, give ':' as an action. 20936 20937AX_LUA_HEADERS: Search for Lua headers. Requires that AX_PROG_LUA be 20938expanded before this macro. Adds precious variable LUA_INCLUDE, which 20939may contain Lua specific include flags, e.g. -I/usr/include/lua5.1. If 20940LUA_INCLUDE is blank, then this macro will attempt to find suitable 20941flags. 20942 20943LUA_INCLUDE can be used by Automake to compile Lua modules or 20944executables with embedded interpreters. The *_CPPFLAGS variables should 20945be used for this purpose, e.g. myprog_CPPFLAGS = $(LUA_INCLUDE). 20946 20947This macro searches for the header lua.h (and others). The search is 20948performed with a combination of CPPFLAGS, CPATH, etc, and LUA_INCLUDE. 20949If the search is unsuccessful, then some common directories are tried. 20950If the headers are then found, then LUA_INCLUDE is set accordingly. 20951 20952The paths automatically searched are: 20953 20954 * /usr/include/luaX.Y 20955 * /usr/include/lua/X.Y 20956 * /usr/include/luaXY 20957 * /usr/local/include/luaX.Y 20958 * /usr/local/include/lua-X.Y 20959 * /usr/local/include/lua/X.Y 20960 * /usr/local/include/luaXY 20961 20962(Where X.Y is the Lua version number, e.g. 5.1.) 20963 20964The Lua version number found in the headers is always checked to match 20965the Lua interpreter's version number. Lua headers with mismatched 20966version numbers are not accepted. 20967 20968If headers are found, then ACTION-IF-FOUND is performed, otherwise 20969ACTION-IF-NOT-FOUND is performed. If ACTION-IF-NOT-FOUND is blank, then 20970it will default to printing an error. To prevent the default behavior, 20971set the action to ':'. 20972 20973AX_LUA_LIBS: Search for Lua libraries. Requires that AX_PROG_LUA be 20974expanded before this macro. Adds precious variable LUA_LIB, which may 20975contain Lua specific linker flags, e.g. -llua5.1. If LUA_LIB is blank, 20976then this macro will attempt to find suitable flags. 20977 20978LUA_LIB can be used by Automake to link Lua modules or executables with 20979embedded interpreters. The *_LIBADD and *_LDADD variables should be 20980used for this purpose, e.g. mymod_LIBADD = $(LUA_LIB). 20981 20982This macro searches for the Lua library. More technically, it searches 20983for a library containing the function lua_load. The search is performed 20984with a combination of LIBS, LIBRARY_PATH, and LUA_LIB. 20985 20986If the search determines that some linker flags are missing, then those 20987flags will be added to LUA_LIB. 20988 20989If libraries are found, then ACTION-IF-FOUND is performed, otherwise 20990ACTION-IF-NOT-FOUND is performed. If ACTION-IF-NOT-FOUND is blank, then 20991it will default to printing an error. To prevent the default behavior, 20992set the action to ':'. 20993 20994AX_LUA_READLINE: Search for readline headers and libraries. Requires 20995the AX_LIB_READLINE macro, which is provided by ax_lib_readline.m4 from 20996the Autoconf Archive. 20997 20998If a readline compatible library is found, then ACTION-IF-FOUND is 20999performed, otherwise ACTION-IF-NOT-FOUND is performed. 21000 21001Source Code 21002*********** 21003 21004Download the latest version of 'ax_lua.m4' 21005(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=blob_plain;f=m4/ax_lua.m4) 21006or browse the macro's revision history 21007(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=history;f=m4/ax_lua.m4). 21008 21009License 21010******* 21011 21012Copyright (C) 2015 Reuben Thomas <rrt@sc3d.org> 21013Copyright (C) 2014 Tim Perkins <tprk77@gmail.com> 21014 21015This program is free software: you can redistribute it and/or modify it 21016under the terms of the GNU General Public License as published by the 21017Free Software Foundation, either version 3 of the License, or (at your 21018option) any later version. 21019 21020This program is distributed in the hope that it will be useful, but 21021WITHOUT ANY WARRANTY; without even the implied warranty of 21022MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

It also sets MPILIBS to any libraries that 21214are needed for linking MPI (e.g. -lmpi or -lfmpi, if a special 21215MPICC/MPICXX/MPIF77/MPIFC was not found). 21216 21217Note that this macro should be used only if you just have a few source 21218files that need to be compiled using MPI. In particular, you should 21219neither overwrite CC/CXX/F77/FC with the values of 21220MPICC/MPICXX/MPIF77/MPIFC, nor assume that you can use the same flags 21221etc. as the standard compilers. If you want to compile a whole program 21222using the MPI compiler commands, use one of the macros 21223AX_PROG_{CC,CXX,FC}_MPI. 21224 21225ACTION-IF-FOUND is a list of shell commands to run if an MPI library is 21226found, and ACTION-IF-NOT-FOUND is a list of commands to run if it is not 21227found.

For instance let's say that you want 21409 # to append '/subpath': 21410 filename="$filename/subpath" 21411 # finally switch back to the original notation 21412 AX_NORMALIZE_PATH([filename], ["$old_filename"]) 21413 # now $filename equals to 'A:\FOO\BAR\subpath' 21414 21415One good reason to make all path processing with the unix convention is 21416that backslashes have a special meaning in many cases. For instance 21417 21418 expr 'A:\FOO' : 'A:\Foo' 21419 21420will return 0 because the second argument is a regex in which 21421backslashes have to be backslashed. In other words, to have the two 21422strings to match you should write this instead: 21423 21424 expr 'A:\Foo' : 'A:\\Foo' 21425 21426Such behavior makes DOS filenames extremely unpleasant to work with. So 21427temporary turn your paths to the Unix notation, and revert them to the 21428original notation after the processing. See the macro 21429AX_COMPUTE_RELATIVE_PATHS for a concrete example of this. 21430 21431REFERENCE_STRING defaults to $VARIABLE, this means that slashes will be 21432converted to backslashes if $VARIABLE already contains some backslashes 21433(see $thirddir below). 21434 21435 firstdir='/usr/local//share' 21436 seconddir='C:\Program Files\\' 21437 thirddir='C:\home/usr/' 21438 AX_NORMALIZE_PATH([firstdir]) 21439 AX_NORMALIZE_PATH([seconddir]) 21440 AX_NORMALIZE_PATH([thirddir]) 21441 # $firstdir = '/usr/local/share' 21442 # $seconddir = 'C:\Program Files' 21443 # $thirddir = 'C:\home\usr' 21444 21445Source Code 21446*********** 21447 21448Download the latest version of 'ax_normalize_path.m4' 21449(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=blob_plain;f=m4/ax_normalize_path.m4) 21450or browse the macro's revision history 21451(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=history;f=m4/ax_normalize_path.m4). 21452 21453License 21454******* 21455 21456Copyright (C) 2008 Alexandre Duret-Lutz <adl@gnu.org> 21457 21458This program is free software; you can redistribute it and/or modify it 21459under the terms of the GNU General Public License as published by the 21460Free Software Foundation; either version 2 of the License, or (at your 21461option) any later version. 21462 21463This program is distributed in the hope that it will be useful, but 21464WITHOUT ANY WARRANTY; without even the implied warranty of 21465MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

It defines 21623"UA_NO_AMALGAMATION" if necessary. 21624 21625The individual headers to check for if no amalgamation is found can be 21626provided as a space-separated list in the first argument. If that is 21627empty, it defaults to all files known to be contained in the 21628amalgamation as of v0.2.0 of the library: 21629 21630 * ms_stdint.h 21631 * ua_client.h 21632 * ua_client_highlevel.h 21633 * ua_config.h 21634 * ua_config_standard.h 21635 * ua_connection.h 21636 * ua_constants.h 21637 * ua_job.h 21638 * ua_log.h 21639 * ua_log_stdout.h 21640 * ua_network_tcp.h 21641 * ua_nodeids.h 21642 * ua_server.h 21643 * ua_server_external_ns.h 21644 * ua_types.h 21645 * ua_types_generated.h 21646 * ua_types_generated_handling.h 21647 21648If the with_open62541 shell variable is set to "no" (e.g. from running 21649the AX_OPEN62541_PATH macro and the user giving configure the option 21650"-without-open62541"), then expands ACTION-IF-NOT-FOUND without any 21651checks. 21652 21653[1]: <http://open62541.org/> 21654 21655Source Code 21656*********** 21657 21658Download the latest version of 'ax_open62541_check_h.m4' 21659(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=blob_plain;f=m4/ax_open62541_check_h.m4) 21660or browse the macro's revision history 21661(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=history;f=m4/ax_open62541_check_h.m4). 21662 21663License 21664******* 21665 21666Copyright (C) 2016,2017 Olaf Mandel <olaf@mandel.name> 21667 21668Copying and distribution of this file, with or without modification, are 21669permitted in any medium without royalty provided the copyright notice 21670and this notice are preserved.

The 21692AX_OPEN62541_CHECK_LIB macro can search for both and adds the first one 21693found to the LIBS Makefile variable. The search can be in either order 21694(shared first or static first), which is selectable on macro invocation 21695with the STATIC-FIRST parameter. The user can change this default by 21696invoking configure with either the -with-open62541-shared or 21697-with-open62541-static option (the named one is checked first). 21698 21699Either shared or static library can be excluded from checking completely 21700with the options -without-open62541-shared and 21701-without-open62541-static. 21702 21703If the with_open62541 shell variable is set to "no" (e.g. from running 21704the AX_OPEN62541_PATH macro and the user giving configure the option 21705"-without-open62541"), then expands ACTION-IF-NOT-FOUND without any 21706checks.

In that case, the location of several directories need to be 21749added to the pre-processor and linker search paths: 21750 21751 * -I<src>/deps 21752 * -I<src>/include 21753 * -I<src>/plugins 21754 * -I<build>/src_generated 21755 * -I<build> 21756 * -L<build> 21757 21758Here "src" indicates the location of the library source directory and 21759"build" the location of the out-of-source build. 21760 21761This macro provides the configure options -with-open62541=dir and 21762-with-open62541-build=dir to set the two directories. This macro will 21763append to CPPFLAGS and LDFLAGS if a dir is supplied. It will also 21764export LD_LIBRARY_PATH with the absolute path of the build dir for the 21765rest of the configure script to use and define a Makefile variable 21766OPEN62541_LDPATH, which contains 21767LD_LIBRARY_PATH=$LD_LIBRARY_PATH:<abs_path_to_build> : this is intended 21768to be used for all commands that need to execute a program using the 21769library (e.g. make check). If paths are set, they are forwarded to 21770distcheck. 21771 21772For -with-open62541, the dir is optional: if either the values "no" 21773(from -without-open62541) or "yes" (for no argument) are specified, this 21774macro does nothing but these values may be used by other code. If 21775-with-open62541 is not specified, the variable with_open62541 is not 21776set. 21777 21778For -with-open62541-build, the dir is compulsory. -with-open62541-build 21779must not be given without also specifying -with-open62541.

Since libtool assumes 21901that there is no subroutine-facility in the shell invoked, these are not 21902actually subroutines, but actually a "list of commands". This looks 21903correct, but the command separator is not ";" - it is "~", the tilde 21904character. 21905 21906Now, grep again, look for 'grep 'IFS="~"' libtool' and see that libtool 21907scripting uses a for-loop on the command-list, i.e for cmd in 21908$some_cmds. This works correctly when the IFS was modified, where IFS 21909stands for "input field separator" which is whitespace characters by 21910default. 21911 21912The problem: I have some real-world filesystems where there are 21913directories using "~" inside of them, to be more to the point, it is a 21914change control management software that uses source repositories of the 21915form "path/master/project~version/src" and libtool has the tendency to 21916resolve any symlinks so that it will paste such path into the $_cmds 21917script when it gets evaluated a number of times. 21918 21919This script is a workaround: I do not know why the ";" was not chosen as 21920the IFS, perhaps it has some weird interactions in some shells since it 21921is also the default record separator being one time bigger in context 21922than the argument separator. I have made good success however with 21923using "?" as the IFS, since there is no path-name that uses a question 21924mark, and there is no _cmds ever around that uses "?" for some thing. 21925 21926Oh yes, there are some usages of "*" to match shell-wise at the output 21927file of some tool, so that might have triggered the choice to not use 21928"?" in the first place - but in real life it never occurred that a 21929_cmds script was created that has gone to use "?". And so, this 21930ac-macro exchanges the s/~/?/g in configured _cmds variables and 21931replaces all occurrences of s/IFS="~"/IFS="?"/ - and it all works smooth 21932now. 21933 21934Source Code 21935*********** 21936 21937Download the latest version of 'ax_patch_libtool_changing_cmds_ifs.m4' 21938(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=blob_plain;f=m4/ax_patch_libtool_changing_cmds_ifs.m4) 21939or browse the macro's revision history 21940(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=history;f=m4/ax_patch_libtool_changing_cmds_ifs.m4). 21941 21942License 21943******* 21944 21945Copyright (C) 2008 Guido U.

If 21968MINIMUM-VERSION is specified, it will ensure that the library found is 21969at least that version. 21970 21971It determines the name of the library as well as the path to the header 21972file and library. It will check both the default environment as well as 21973the default Berkeley DB install location. When found, it sets BDB_LIBS, 21974BDB_CPPFLAGS, and BDB_LDFLAGS to the necessary values to add to LIBS, 21975CPPFLAGS, and LDFLAGS, as well as setting BDB_VERSION to the version 21976found. HAVE_DB_H is defined also. 21977 21978The option -with-bdb-dir=DIR can be used to specify a specific Berkeley 21979DB installation to use. 21980 21981An example of it's use is: 21982 21983 AX_PATH_BDB([3],[ 21984 LIBS="$BDB_LIBS $LIBS" 21985 LDFLAGS="$BDB_LDFLAGS $LDFLAGS" 21986 CPPFLAGS="$CPPFLAGS $BDB_CPPFLAGS" 21987 ]) 21988 21989which will locate the latest version of Berkeley DB on the system, and 21990ensure that it is version 3.0 or higher. 21991 21992Details: This macro does not use either AC_CHECK_HEADERS or AC_CHECK_LIB 21993because, first, the functions inside the library are sometimes renamed 21994to contain a version code that is only available from the db.h on the 21995system, and second, because it is common to have multiple db.h and libdb 21996files on a system it is important to make sure the ones being used 21997correspond to the same version. Additionally, there are many different 21998possible names for libdb when installed by an OS distribution, and these 21999need to be checked if db.h does not correspond to libdb. 22000 22001When cross compiling, only header versions are verified since it would 22002be difficult to check the library version. Additionally the default 22003Berkeley DB installation locations /usr/local/BerkeleyDB* are not 22004searched for higher versions of the library. 22005 22006The format for the list of library names to search came from the Cyrus 22007IMAP distribution, although they are generated dynamically here, and 22008only for the version found in db.h. 22009 22010The macro AX_COMPARE_VERSION is required to use this macro, and should 22011be available from the Autoconf Macro Archive. 22012 22013The author would like to acknowledge the generous and valuable feedback 22014from Guido Draheim, without which this macro would be far less robust, 22015and have poor and inconsistent cross compilation support. 22016 22017Changes: 22018 22019 1/5/05 applied patch from Rafal Rzepecki to eliminate compiler 22020 warning about unused variable, argv 22021 22022Source Code 22023*********** 22024 22025Download the latest version of 'ax_path_bdb.m4' 22026(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=blob_plain;f=m4/ax_path_bdb.m4) 22027or browse the macro's revision history 22028(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=history;f=m4/ax_path_bdb.m4). 22029 22030License 22031******* 22032 22033Copyright (C) 2008 Tim Toolan <toolan@ele.uri.edu> 22034 22035Copying and distribution of this file, with or without modification, are 22036permitted in any medium without royalty provided the copyright notice 22037and this notice are preserved.

If MINIMUM-VERSION 22058is specified, the script must also support the '-version' arg. If the 22059'-with-library-[exec-]prefix' arguments to ./configure are given, it 22060must also support '-prefix' and '-exec-prefix'. Preferably use 22061CONFIG-SCRIPTS as config script, CFLAGS-ARG instead of '-cflags' and 22062LIBS-ARG instead of '-libs', if given. 22063 22064The SED-EXPR-EXTRACTOR parameter represents the expression used in sed 22065to extract the version number. Use it if your 'foo-config -version' 22066dumps something like 'Foo library v1.0.0 (alfa)' instead of '1.0.0'. 22067 22068The macro respects LIBRARY_CONFIG, LIBRARY_CFLAGS and LIBRARY_LIBS 22069variables. If the first one is defined, it specifies the name of the 22070config script to use. If the latter two are defined, the script is not 22071ran at all and their values are used instead (if only one of them is 22072defined, the empty value of the remaining one is still used). 22073 22074Example: 22075 22076 AX_PATH_GENERIC(Foo, 1.0.0) 22077 22078would run 'foo-config -version' and check that it is at least 1.0.0, if 22079successful the following variables would be defined and substituted: 22080 22081 FOO_CFLAGS to `foo-config --cflags` 22082 FOO_LIBS to `foo-config --libs` 22083 22084Example: 22085 22086 AX_PATH_GENERIC([Bar],,,[ 22087 AC_MSG_ERROR([Cannot find Bar library]) 22088 ]) 22089 22090would check for bar-config program, defining and substituting the 22091following variables: 22092 22093 BAR_CFLAGS to `bar-config --cflags` 22094 BAR_LIBS to `bar-config --libs` 22095 22096Example: 22097 22098 ./configure BAZ_LIBS=/usr/lib/libbaz.a 22099 22100would link with a static version of baz library even if 'baz-config 22101-libs' returns just "-lbaz" that would normally result in using the 22102shared library. 22103 22104This macro is a rearranged version of AC_PATH_GENERIC from Angus Lees. 22105 22106Source Code 22107*********** 22108 22109Download the latest version of 'ax_path_generic.m4' 22110(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=blob_plain;f=m4/ax_path_generic.m4) 22111or browse the macro's revision history 22112(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=history;f=m4/ax_path_generic.m4). 22113 22114License 22115******* 22116 22117Copyright (C) 2009 Francesco Salvestrini <salvestrini@users.sourceforge.net> 22118 22119Copying and distribution of this file, with or without modification, are 22120permitted in any medium without royalty provided the copyright notice 22121and this notice are preserved.

When successful, it sets the output variable 22182MILTER_LIBS to "-lmilter", MILTER_LDFLAGS to contain an -Lpathtolib 22183option, and MILTER_CPPFLAGS to contain an -Ipathtoinclude option, if 22184they are necessary. 22185 22186The easiest way to use this macro is something like: 22187 22188 AX_PATH_MILTER([8.12],[ 22189 LIBS="$MILTER_LIBS $LIBS" 22190 LDFLAGS="$MILTER_LDFLAGS $LDFLAGS" 22191 CPPFLAGS="$CPPFLAGS $MILTER_CPPFLAGS" 22192 ],[ 22193 AC_MSG_ERROR([required milter library and header not found]) 22194 ]) 22195 22196If the macro is successful, it just adds any flags to the necessary 22197environment. If it is not successful, it would likely be a fatal error, 22198because if an application is linking with libmilter.a, it is probably 22199because it is a milter. 22200 22201There are two optional "-with" options for configure which are added. 22202If they are specified, they override any searching that is done. They 22203are: 22204 22205 --with-sendmail-base=<DIR> This option is used to explicitly 22206 specify the base of the sendmail distribution. 22207 22208 --with-sendmail-obj=<DIR> The option is used to explicitly specify 22209 the "obj.*" subdirectory in the sendmail distribution 22210 that should be used. 22211 22212When sendmail-base is not specified, the current environment is first 22213tested to see if the header and library are available, and if so 22214MILTER_LDFLAGS and MILTER_CPPFLAGS are left empty. 22215 22216There are two places that are searched for the sendmail base directory. 22217The first location is one directory down from the current directory. It 22218checks if there is a directory of the form sendmail-8.1*, limited to 22219version 8.12.x or higher, then chooses the directory with the highest 22220version number. If that method does not succeed, it then looks in the 22221file /etc/mail/sendmail.cf for the directory it was built from, and uses 22222the base of that distribution. If neither of these methods work, then 22223it fails. 22224 22225There are two methods for finding the "obj.*" directory when it is not 22226specified. The first is to try to run sendmail's Build program with the 22227-M option which will print out the name of the obj. directory for the 22228tool in the directory where it is run from. If this does not work, is 22229looks for the newest directory of the form "obj.*" in the sendmail base 22230directory. 22231 22232Two addition output variables that are defined, whether or not the files 22233are found are SENDMAIL_BASE_DIR and SENDMAIL_OBJ_DIR, which are the 22234suspected location of the sendmail base directory and obj.* 22235subdirectory. 22236 22237NOTE: POSIX threads MUST be configured BEFORE this function is called or 22238it will not find libmilter.a even if it exists. The easiest way is to 22239use the AX_PTHREAD macro by Steven G. Johnson and Alejandro Forero 22240Cuervo which is available from the Autoconf Macro Archive. 22241 22242Source Code 22243*********** 22244 22245Download the latest version of 'ax_path_milter.m4' 22246(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=blob_plain;f=m4/ax_path_milter.m4) 22247or browse the macro's revision history 22248(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=history;f=m4/ax_path_milter.m4). 22249 22250License 22251******* 22252 22253Copyright (C) 2008 Tim Toolan <toolan@ele.uri.edu> 22254 22255Copying and distribution of this file, with or without modification, are 22256permitted in any medium without royalty provided the copyright notice 22257and this notice are preserved.

These two 22601variables are exposed via AC_SUBST, and should be used in a pkg-config 22602file as the substituted values for Requires and Requires.private. 22603 22604The PREFIX, PUBLIC-MODULES and PRIVATE-MODULES arguments should be 22605specified as for PKG_CHECK_MODULES, with the concatenation of 22606PUBLIC-MODULES and PRIVATE-MODULES equaling the LIST-OF-MODULES from 22607PKG_CHECK_MODULES. The ACTION-IF-FOUND and ACTION-IF-NOT-FOUND arguments 22608are optional, and should also be specified as for PKG_CHECK_MODULES. 22609ACTION-IF-FOUND is evaluated if the full LIST-OF-MODULES is found; 22610ACTION-IF-NOT-FOUND similarly. 22611 22612PUBLIC-VARIABLE defaults to AX_PACKAGE_REQUIRES, and PRIVATE-VARIABLE 22613defaults to AX_PACKAGE_REQUIRES_PRIVATE. Both variables are AC_SUBST-ed 22614by this macro. 22615 22616For example: 22617 22618 AX_PKG_CHECK_MODULES([GLIB],[glib-2.0 gio-2.0],[gthread-2.0]) 22619 AX_PKG_CHECK_MODULES([DBUS],[],[dbus-glib-1 >= 0.98 dbus-1]) 22620 22621results in the substitutions: 22622 22623 AX_PACKAGE_REQUIRES="glib-2.0 gio-2.0" 22624 AX_PACKAGE_REQUIRES_PRIVATE="gthread-2.0 dbus-glib-1 >= 0.98 dbus-1" 22625 22626and can be used with a template pkg-config file (.pc.in) using: 22627 22628 Requires: @AX_PACKAGE_REQUIRES@ 22629 Requires.private: @AX_PACKAGE_REQUIRES_PRIVATE@ 22630 22631Source Code 22632*********** 22633 22634Download the latest version of 'ax_pkg_check_modules.m4' 22635(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=blob_plain;f=m4/ax_pkg_check_modules.m4) 22636or browse the macro's revision history 22637(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=history;f=m4/ax_pkg_check_modules.m4). 22638 22639License 22640******* 22641 22642Copyright (C) 2014 Philip Withnall <philip@tecnocode.co.uk> 22643 22644Copying and distribution of this file, with or without modification, are 22645permitted in any medium without royalty provided the copyright notice 22646and this notice are preserved.

MICO (Mico 22664Is COrba) installs the file 'mico-setup.sh' under MICO_INSTALL_BASE/lib, 22665where MICO_INSTALL_BASE is probably /usr/local or /usr. If nothing was 22666specified when calling configure or just -with-mico, it searches in 22667$prefix/lib:/usr/local/lib:/usr/lib The argument of s-with-mico 22668specifies the full pathname of the mico-setup.sh file. For instance 22669-with-mico=/usr/local/mico-2.2.6/lib/mico-setup.sh. 22670 22671If the version argument is given (e.g. 2.2.6), AX_PKG_MICO checks that 22672the mico package is this version number or higher. 22673 22674The other optional argument to AX_PKG_MICO are 'optional' and 22675'required'. by default, placing AX_PKG_MICO in your configure.in does 22676not enforce using mico, if it is not found on the system. If MICO 22677existence is critical for the building of your package, then you 22678probably want to specify something like "AX_PKG_MICO(2.2.6 required)". 22679Then, even if the -with-mico was not specified on the command line of 22680the configure script, an error will be raised if mico was not found. 22681 22682If the mico package is not found, abort configuration with error 22683message. 22684 22685It defines the symbol MICOSETUP, MICOVERSION, MICOSHAREDDIR 22686MICO_INCLUDE, MICO_LIB and MICO_CXX if mico is found. In addition, the 22687mico script mico-c++ (set in (MICO_CXX) is scaned for a string match 22688"-I.*ministl" and if foundMICO_USE_MINISTL is set to 1, otherwise to 0. 22689 22690Example of use of these variables in your Makefile.in: 22691 22692 INCLUDES += @MICO_INCLUDE@ 22693 LDFLAGS += @MICO_LIB@ 22694 22695Source Code 22696*********** 22697 22698Download the latest version of 'ax_pkg_mico.m4' 22699(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=blob_plain;f=m4/ax_pkg_mico.m4) 22700or browse the macro's revision history 22701(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=history;f=m4/ax_pkg_mico.m4). 22702 22703License 22704******* 22705 22706Copyright (C) 2008 Tal Shalif <tal@shalif.com> 22707 22708Copying and distribution of this file, with or without modification, are 22709permitted in any medium without royalty provided the copyright notice 22710and this notice are preserved.

If found, 22728then SWIG is AC_SUBST'd; if not found, then $SWIG is empty. If SWIG is 22729found, then SWIG_LIB is set to the SWIG library path, and AC_SUBST'd. 22730 22731You can use the optional first argument to check if the version of the 22732available SWIG is greater than or equal to the value of the argument. 22733It should have the format: N[.N[.N]] (N is a number between 0 and 999. 22734Only the first N is mandatory.)

No need to invent some "mylib-confdefs.h.in" manually. 22852 22853Note that some AC_DEFINEs that end up in the config.h file are actually 22854self-referential - e.g. AC_C_INLINE, AC_C_CONST, and the AC_TYPE_OFF_T 22855say that they "will define inline|const|off_t if the system does not do 22856it by itself". You might want to clean up about these - consider an 22857extra mylib/conf.h that reads something like: 22858 22859 #include <mylib/_config.h> 22860 #ifndef _testpkg_const 22861 #define _testpkg_const const 22862 #endif 22863 22864and then start using _testpkg_const in the header files. That is also a 22865good thing to differentiate whether some library-user has starting to 22866take up with a different compiler, so perhaps it could read something 22867like this: 22868 22869 #ifdef _MSC_VER 22870 #include <mylib/_msvc.h> 22871 #else 22872 #include <mylib/_config.h> 22873 #endif 22874 #ifndef _testpkg_const 22875 #define _testpkg_const const 22876 #endif 22877 22878Source Code 22879*********** 22880 22881Download the latest version of 'ax_prefix_config_h.m4' 22882(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=blob_plain;f=m4/ax_prefix_config_h.m4) 22883or browse the macro's revision history 22884(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=history;f=m4/ax_prefix_config_h.m4). 22885 22886License 22887******* 22888 22889Copyright (C) 2014 Reuben Thomas <rrt@sc3d.org> 22890Copyright (C) 2008 Guido U.

All these variables but GCC_FOR_BUILD are 23266substituted in the Makefile. 23267 23268Source Code 23269*********** 23270 23271Download the latest version of 'ax_prog_cc_for_build.m4' 23272(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=blob_plain;f=m4/ax_prog_cc_for_build.m4) 23273or browse the macro's revision history 23274(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=history;f=m4/ax_prog_cc_for_build.m4). 23275 23276License 23277******* 23278 23279Copyright (C) 2008 Paolo Bonzini <bonzini@gnu.org> 23280 23281Copying and distribution of this file, with or without modification, are 23282permitted in any medium without royalty provided the copyright notice 23283and this notice are preserved.

The macro has to 23303be used instead of the standard macro AC_PROG_CC and will replace the 23304standard variable CC with the found compiler. 23305 23306MPI-WANTED-TEST is used to test whether MPI is actually wanted by the 23307user. If MPI-WANTED_TEST is omitted or if it succeeds, the macro will 23308try to find out how to use MPI, if it fails, the macro will call 23309AC_PROG_CC to find a standard C compiler instead. 23310 23311When MPI is found, ACTION-IF-FOUND will be executed, if MPI is not found 23312(or MPI-WANTED-TEST fails) ACTION-IF-NOT-FOUND is executed. If 23313ACTION-IF-FOUND is not set, the macro will define HAVE_MPI. 23314 23315The following example demonstrates usage of the macro: 23316 23317 # If --with-mpi=auto is used, try to find MPI, but use standard C compiler if it is not found. 23318 # If --with-mpi=yes is used, try to find MPI and fail if it isn't found. 23319 # If --with-mpi=no is used, use a standard C compiler instead. 23320 AC_ARG_WITH(mpi, [AS_HELP_STRING([--with-mpi], 23321 [compile with MPI (parallelization) support.

The actual value is assured to be 23390either LN_S (if the filesystem supports symbolic links) or CP (if the 23391filesystem does not know about symbolic links and you need a copy of 23392original file to have the same text in both places). In a gnu 23393environment it will simply set CP_S="cp -s" since the gnu "cp"-command 23394has the "-s" flag. You shall not try to use this command on directories 23395since it would require a "-r" in the case of a copy that is not 23396supported explicitly here. (I'm not sure if some "cp"-commands out 23397there would barf at usage of "-r" on a normal file). 23398 23399Use CP_S to create a copy of read-only data - if your filesystem 23400supports it then a symbolic link is created - a process that is quicker 23401and space-saving. However, if the target fs does not support symbolic 23402links, just copy the data. Unlike ac_prog_ln_s this macro will never 23403fail to set the CP_S ac_subst to something that works. 23404 23405Source Code 23406*********** 23407 23408Download the latest version of 'ax_prog_cp_s.m4' 23409(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=blob_plain;f=m4/ax_prog_cp_s.m4) 23410or browse the macro's revision history 23411(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=history;f=m4/ax_prog_cp_s.m4). 23412 23413License 23414******* 23415 23416Copyright (C) 2008 Guido U.

Supported features are 'DOXYGEN' itself, 'DOT' for 23779generating graphics, 'HTML' for plain HTML, 'CHM' for compressed HTML 23780help (for MS users), 'CHI' for generating a separate .chi file by the 23781.chm file, and 'MAN', 'RTF', 'XML', 'PDF' and 'PS' for the appropriate 23782output formats. The environment variable DOXYGEN_PAPER_SIZE may be 23783specified to override the default 'a4wide' paper size. 23784 23785By default, HTML, PDF and PS documentation is generated as this seems to 23786be the most popular and portable combination. MAN pages created by 23787Doxygen are usually problematic, though by picking an appropriate subset 23788and doing some massaging they might be better than nothing. CHM and RTF 23789are specific for MS (note that you can't generate both HTML and CHM at 23790the same time). The XML is rather useless unless you apply specialized 23791post-processing to it. 23792 23793The macros mainly control the default state of the feature. The use can 23794override the default by specifying -enable or -disable. The macros 23795ensure that contradictory flags are not given (e.g., 23796-enable-doxygen-html and -enable-doxygen-chm, -enable-doxygen-anything 23797with -disable-doxygen, etc.) Finally, each feature will be 23798automatically disabled (with a warning) if the required programs are 23799missing. 23800 23801Once all the feature defaults have been specified, call DX_INIT_DOXYGEN 23802with the following parameters: a one-word name for the project for use 23803as a filename base etc., an optional configuration file name (the 23804default is '$(srcdir)/Doxyfile', the same as Doxygen's default), and an 23805optional output directory name (the default is 'doxygen-doc'). To run 23806doxygen multiple times for different configuration files and output 23807directories provide more parameters: the second, forth, sixth, etc 23808parameter are configuration file names and the third, fifth, seventh, 23809etc parameter are output directories. No checking is done to catch 23810duplicates. 23811 23812Automake Support 23813 23814The DX_RULES substitution can be used to add all needed rules to the 23815Makefile. Note that this is a substitution without being a variable: 23816only the @DX_RULES@ syntax will work. 23817 23818The provided targets are: 23819 23820 doxygen-doc: Generate all doxygen documentation. 23821 23822 doxygen-run: Run doxygen, which will generate some of the 23823 documentation (HTML, CHM, CHI, MAN, RTF, XML) 23824 but will not do the post processing required 23825 for the rest of it (PS, PDF). 23826 23827 doxygen-ps: Generate doxygen PostScript documentation. 23828 23829 doxygen-pdf: Generate doxygen PDF documentation. 23830 23831Note that by default these are not integrated into the automake targets. 23832If doxygen is used to generate man pages, you can achieve this 23833integration by setting man3_MANS to the list of man pages generated and 23834then adding the dependency: 23835 23836 $(man3_MANS): doxygen-doc 23837 23838This will cause make to run doxygen and generate all the documentation. 23839 23840The following variable is intended for use in Makefile.am: 23841 23842 DX_CLEANFILES = everything to clean. 23843 23844Then add this variable to MOSTLYCLEANFILES. 23845 23846Source Code 23847*********** 23848 23849Download the latest version of 'ax_prog_doxygen.m4' 23850(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=blob_plain;f=m4/ax_prog_doxygen.m4) 23851or browse the macro's revision history 23852(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=history;f=m4/ax_prog_doxygen.m4). 23853 23854License 23855******* 23856 23857Copyright (C) 2009 Oren Ben-Kiki <oren@ben-kiki.org> 23858Copyright (C) 2015 Olaf Mandel <olaf@mandel.name> 23859 23860Copying and distribution of this file, with or without modification, are 23861permitted in any medium without royalty provided the copyright notice 23862and this notice are preserved.

The macro has to 23951be used instead of the standard macro AC_PROG_F77 and will replace the 23952standard variable F77 with the found compiler. 23953 23954MPI-WANTED-TEST is used to test whether MPI is actually wanted by the 23955user.

If no value is specified, the macro assumes that 24533the sole target will be named $(PACKAGE_NAME). Thus, the two following 24534lines are equivalent: 24535 24536 AX_PROG_HELP2MAN 24537 AX_PROG_HELP2MAN([\$(PACKAGE_NAME)]) 24538 245392. <man directory prefix>: directory prefix of the man pages directory 24540 24541Sets AX_HELP2MAN_PREFIX_MANS to <man directory prefix>. Defaults to 24542'doc/man/man1' if no value is provided. Note that 24543AX_HELP2MAN_PREFIX_MANS will always be a subdirectory of the build 24544directory. 24545 245463. <binary prefix>: 24547 24548Sets AX_HELP2MAN_PREFIX_BIN to <binary prefix>. Defaults to 24549'$(top_builddir)' if no value is provided. The two following lines are 24550equivalent: 24551 24552 AX_PROG_HELP2MAN([subdir/program1, subdir/program2]) 24553 AX_PROG_HELP2MAN([program1, program2], [], [\$(top_builddir)/subdir]) 24554 24555The macro: 24556 24557- checks that help2man is available on the system. 24558 24559- provides the configure option -disable-help2man. 24560 24561- sets the output variable ax_help2man_MANS to the list of man pages 24562that shall be generated. 24563 24564- sets the automake conditional HAVE_HELP2MAN 24565 24566- sets the substitution variable AX_HELP2MAN_RULES to the required make 24567rules, targets and recipes. 24568 24569Further detail on the macro can be found after the minimal working 24570example. Here is a minimal working example: 24571 24572 # configure.ac: 24573 AX_PROG_HELP2MAN 24574 24575 # Makefile.am: 24576 if HAVE_HELP2MAN 24577 man1_MANS = $(ax_help2man_MANS) 24578 @AX_HELP2MAN_RULES@ 24579 endif 24580 24581This minimal working example shall work under the following assumptions: 24582 245831. the aforementioned binary has the same name as the project 24584 245852. the project produces a single binary at the root of the build 24586directory 24587 245883. the man page shall be generated into the doc/man/man1 directory 24589 24590Note that adding ax_help2man_MANS to man1_MANS is not needed if the man 24591page generation is not mandatory. 24592 24593The AX_HELP2MAN_RULES substitution variable shall contain: 24594 24595- a recipe to create, if necessary, the destination directory. 24596 24597- a generic rule to produce the manpages. 24598 24599This rule targets the contents of the variable ax_help2man_MANS and its 24600recipe shall be akin to the following: 24601 24602 $(HELP2MAN) -l -N --output="$@" --name="$(shell basename $<)" "$(shell dirname $<)/$(shell basename $<)" 24603 24604Errors from this rule are ignored. 24605 24606- rules for each input program and target man page. 24607 24608For each input program, a rule akin to the following shall be available: 24609 24610 $(AX_HELP2MAN_PREFIX_MANS)/program.1: $(AX_HELP2MAN_PREFIX_BIN)/path/to/program 24611 24612The macro assumes that all man pages shall be generated into the same 24613directory (AX_HELP2MAN_PREFIX_MANS) and that all input programs can be 24614found in the same directory (AX_HELP2MAN_PREFIX_BIN). If a subset of the 24615inputs or outputs have different paths (for instance one of the inputs 24616is a script available in $(top_srcdir) whereas the other inputs are 24617programs compiled at build time), it can be customized in the 24618Makefile.am: the target man page must be added to ax_help2man_MANS, so 24619that it becomes a target of the generic rule for man pages and a rule 24620must be added to specify its prerequisite: 24621 24622 ax_help2man_MANS += path/to/output/man/page.1 24623 path/to/output/man/page.1: path/to/input/program.1 24624 24625Here is a full example for a project where binaries 'program1' and 24626'program2' are compiled at build time whereas 'script' is available in 24627the source tree: 24628 24629 # configure.ac: 24630 AX_PROG_HELP2MAN([program1, program2]) 24631 24632 # Makefile.am: 24633 if HAVE_HELP2MAN 24634 man1_MANS = $(ax_help2man_MANS) 24635 @AX_HELP2MAN_RULES@ 24636 ax_help2man_MANS += $(AX_HELP2MAN_PREFIX_MANS)/script.1 24637 $(AX_HELP2MAN_PREFIX_MANS)/script.1: $(top_srcdir)/script 24638 endif 24639 24640Note that this macro should not be called more than once. 24641 24642Source Code 24643*********** 24644 24645Download the latest version of 'ax_prog_help2man.m4' 24646(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=blob_plain;f=m4/ax_prog_help2man.m4) 24647or browse the macro's revision history 24648(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=history;f=m4/ax_prog_help2man.m4). 24649 24650License 24651******* 24652 24653Copyright (C) 2017 Harenome Ranaivoarivony-Razanajato <ranaivoarivony-razanajato@hareno.me> 24654 24655This program is free software; you can redistribute it and/or modify it 24656under the terms of the GNU General Public License as published by the 24657Free Software Foundation; either version 3 of the License, or (at your 24658option) any later version. 24659 24660This program is distributed in the hope that it will be useful, but 24661WITHOUT ANY WARRANTY; without even the implied warranty of 24662MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

It 27285sets the PTHREAD_LIBS output variable to the threads library and linker 27286flags, and the PTHREAD_CFLAGS output variable to any special C compiler 27287flags that are needed. (The user can also force certain compiler 27288flags/libs to be tested by setting these environment variables.) 27289 27290Also sets PTHREAD_CC to any special C compiler that is needed for 27291multi-threaded programs (defaults to the value of CC otherwise). (This 27292is necessary on AIX to use the special cc_r compiler alias.) 27293 27294NOTE: You are assumed to not only compile your program with these flags, 27295but also to link with them as well. For example, you might link with 27296$PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS 27297 27298If you are only building threaded programs, you may wish to use these 27299variables in your default LIBS, CFLAGS, and CC: 27300 27301 LIBS="$PTHREAD_LIBS $LIBS" 27302 CFLAGS="$CFLAGS $PTHREAD_CFLAGS" 27303 CC="$PTHREAD_CC" 27304 27305In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute constant 27306has a nonstandard name, this macro defines PTHREAD_CREATE_JOINABLE to 27307that name (e.g. PTHREAD_CREATE_UNDETACHED on AIX). 27308 27309Also HAVE_PTHREAD_PRIO_INHERIT is defined if pthread is found and the 27310PTHREAD_PRIO_INHERIT symbol is defined when compiling with 27311PTHREAD_CFLAGS. 27312 27313ACTION-IF-FOUND is a list of shell commands to run if a threads library 27314is found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it 27315is not found. If ACTION-IF-FOUND is not specified, the default action 27316will define HAVE_PTHREAD. 27317 27318Please let the authors know if this macro fails on any platform, or if 27319you have any other suggestions or comments. This macro was based on 27320work by SGJ on autoconf scripts for FFTW (http://www.fftw.org/) (with 27321help from M. Frigo), as well as ac_pthread and hb_pthread macros posted 27322by Alejandro Forero Cuervo to the autoconf macro repository.

It provides the $(PYTHON_CPPFLAGS) and $(PYTHON_LIBS) 27519output variables. It also exports $(PYTHON_EXTRA_LIBS) and 27520$(PYTHON_EXTRA_LDFLAGS) for embedding Python in your code. 27521 27522You can search for some particular version of Python by passing a 27523parameter to this macro, for example ">= '2.3.1'", or "== '2.4'". 27524Please note that you *have* to pass also an operator along with the 27525version to match, and pay special attention to the single quotes 27526surrounding the version number. Don't use "PYTHON_VERSION" for this: 27527that environment variable is declared as precious and thus reserved for 27528the end-user. 27529 27530This macro should work for all versions of Python >= 2.1.0. As an end 27531user, you can disable the check for the python version by setting the 27532PYTHON_NOVERSIONCHECK environment variable to something else than the 27533empty string. 27534 27535If you need to use this macro for an older Python version, please 27536contact the authors.

It supports all pythons >= 2.2 which is the first 27605official release containing distutils. Version 2.2 of python was 27606released December 21, 2001. Since it actually executes the python, 27607cross platform configuration will probably not work. Also, most of the 27608platforms supported are consistent until you look into Mac OS X. The 27609python included with it is installed as a framework which is a very 27610different environment to set up the normal tools such as gcc and libtool 27611to deal with. Therefore, once we establish which python that we are 27612going to use, we use its distutils to actually compile and link our 27613modules or applications. 27614 27615At this time, it does NOT support linking with Python statically. It 27616does support dynamic linking. 27617 27618This set of macros help define $PYTHON, $PYTHON_USE, $PYTHON_CSPEC and 27619$PYTHON_LSPEC. $PYTHON defines the full executable path for the Python 27620being linked to and is used within these macros to determine if that has 27621been specified or found. These macros do execute this python version so 27622it must be present on the system at configure time. 27623 27624$PYTHON_USE is an automake variable that defines whether Python support 27625should be included or not in your application. $PYTHON_CSPEC is a 27626variable that supplies additional CFLAGS for the compilation of the 27627application/shared library. $PYTHON_LSPEC is a variable that supplies 27628additional LDFLAGS for linking the application/shared library. 27629 27630The following is an example of how to set up for python usage within 27631your application in your configure.in: 27632 27633 AX_PYTHON_DEFAULT( ) 27634 AX_PYTHON_ENABLE( ) # Optional 27635 AX_PYTHON_WITH( ) # Optional 27636 AX_PYTHON_PATH( ) # or AX_PYTHON_INSIST( ) 27637 # if $PYTHON is not defined, then the following do nothing. 27638 AX_PYTHON_VERSION_ENSURE( [2.2] ) 27639 AX_PYTHON_CSPEC 27640 AX_PYTHON_LSPEC 27641 27642The AX_PYTHON_DEFAULT sets the $PYTHON_USE to false. Thereby, excluding 27643it if it was optional. 27644 27645The AX_PYTHON_ENABLE looks for the optional configure parameters of 27646-enable-python/-disable-python and establishes the $PYTHON and 27647$PYTHON_USE variables accordingly. 27648 27649The AX_PYTHON_WITH looks for the optional configure parameters of 27650-with-python/-without-python and establishes the $PYTHON and $PYTHON_USE 27651variables accordingly. 27652 27653The AX_PYTHON_PATH looks for python assuming that none has been 27654previously found or defined and issues an error if it does not find it. 27655If it does find it, it establishes the $PYTHON and $PYTHON_USE variables 27656accordingly. AX_PYTHON_INSIST could be used here instead if you want to 27657insist that Python support be included using the -enable-python or 27658-with-python checks previously done. 27659 27660The AX_PYTHON_VERSION_ENSURE issues an error if the Python previously 27661found is not of version 2.2 or greater. 27662 27663Once that these macros have be run, we can use PYTHON_USE within the 27664makefile.am file to conditionally add the Python support such as: 27665 27666Makefile.am example showing optional inclusion of directories: 27667 27668 if PYTHON_USE 27669 plugins = plugins 27670 src = src 27671 else 27672 plugins = 27673 src = 27674 endif 27675 27676 SUBDIRS = . $(plugins) $(src) 27677 27678Makefile.am example showing optional shared library build: 27679 27680 if PYTHON_USE 27681 lib_LTLIBRARIES = libElemList.la 27682 libElemList_la_SOURCES = libElemList.c 27683 libElemList_la_CFLAGS = @PYTHON_CSPEC@ 27684 libElemList_la_LDFLAGS = @PYTHON_LSPEC@ 27685 endif 27686 27687Makefile.am example showing optional program build: 27688 27689 if PYTHON_USE 27690 bin_PROGRAMS = runFunc 27691 runFunc_SOURCES = runFunc.c 27692 runFunc_CFLAGS = @PYTHON_CSPEC@ 27693 runFunc_LDFLAGS = @PYTHON_LSPEC@ 27694 endif 27695 27696The above compiles the modules only if PYTHON_USE was specified as true. 27697Also, the else portion of the if was optional. 27698 27699Source Code 27700*********** 27701 27702Download the latest version of 'ax_python_embed.m4' 27703(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=blob_plain;f=m4/ax_python_embed.m4) 27704or browse the macro's revision history 27705(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=history;f=m4/ax_python_embed.m4). 27706 27707License 27708******* 27709 27710Copyright (C) 2008 Robert White <kranki@mac.com> 27711Copyright (C) 2008 Dustin J.

This macro can be used multiple times. All arguments 29060of this macro must be comma-separated lists. 29061 29062All command line arguments from the parent configure script will be 29063given to the subdirectory configure script after the following 29064modifications (in that order): 29065 290661. The arguments from the 'mandatory arguments' list shall always be 29067appended to the argument list. 29068 290692. The arguments from the 'possibly merged arguments' list shall be 29070added if not present in the arguments of the parent configure script or 29071merged with the existing argument otherwise. 29072 290733. The arguments from the 'replacement arguments' list shall be added 29074if not present in the arguments of the parent configure script or 29075replace the existing argument otherwise. 29076 290774. The arguments from the 'forbidden arguments' list shall always be 29078removed from the argument list. 29079 29080The lists 'mandatory arguments' and 'forbidden arguments' can hold any 29081kind of argument. The 'possibly merged arguments' and 'replacement 29082arguments' expect their arguments to be of the form -option-name=value. 29083 29084This macro aims to remain as close as possible to the AC_CONFIG_SUBDIRS 29085macro. It corrects the paths for '-cache-file' and '-srcdir' and adds 29086'-disable-option-checking' and '-silent' if necessary. 29087 29088This macro also sets the output variable subdirs_extra to the list of 29089directories recorded with AX_SUBDIRS_CONFIGURE. This variable can be 29090used in Makefile rules or substituted in configured files. 29091 29092This macro shall do nothing more than managing the arguments of the 29093configure script. Just like when using AC_CONFIG_SUBDIRS, it is up to 29094the user to check any requirements or define and substitute any required 29095variable for the remainder of the project. 29096 29097Configure scripts recorded with AX_SUBDIRS_CONFIGURE may be executed 29098before configure scripts recorded with AC_CONFIG_SUBDIRS. 29099 29100Without additional arguments, the behaviour of AX_SUBDIRS_CONFIGURE 29101should be identical to the behaviour of AC_CONFIG_SUBDIRS, apart from 29102the contents of the variables subdirs and subdirs_extra (except that 29103AX_SUBDIRS_CONFIGURE expects a comma-separated m4 list): 29104 29105 AC_CONFIG_SUBDIRS([something]) 29106 AX_SUBDIRS_CONFIGURE([something]) 29107 29108This macro may be called multiple times. 29109 29110Usage example: 29111 29112Let us assume our project has 4 dependencies, namely A, B, C and D. Here 29113are some characteristics of our project and its dependencies: 29114 29115- A does not require any special option. 29116 29117- we want to build B with an optional feature which can be enabled with 29118its configure script's option '-enable-special-feature'. 29119 29120- B's configure script is strange and has an option '-with-B=build'. 29121After close inspection of its documentation, we don't want B to receive 29122this option. 29123 29124- C and D both need B. 29125 29126- Just like our project, C and D can build B themselves with the option 29127'-with-B=build'. 29128 29129- We want C and D to use the B we build instead of building it 29130themselves. 29131 29132Our top-level configure script will be called as follows: 29133 29134 $ <path/to/configure> --with-A=build --with-B=build --with-C=build \ 29135 --with-D=build --some-option 29136 29137Thus we have to make sure that: 29138 29139- neither B, C or D receive the option '-with-B=build' 29140 29141- C and D know where to find the headers and libraries of B. 29142 29143Under those conditions, we can use the AC_CONFIG_SUBDIRS macro for A, 29144but need to use AX_SUBDIRS_CONFIGURE for B, C and D: 29145 29146- B must receive '-enable-special-feature' but cannot receive 29147'-with-B=build' 29148 29149- C and D cannot receive '-with-B=build' (or else it would be built 29150thrice) and need to be told where to find B (since we are building it, 29151it would probably not be available in standard paths). 29152 29153Here is a configure.ac snippet that solves our problem: 29154 29155 AC_CONFIG_SUBDIRS([dependencies/A]) 29156 AX_SUBDIRS_CONFIGURE( 29157 [dependencies/B], [--enable-special-feature], [], [], 29158 [--with-B=build]) 29159 AX_SUBDIRS_CONFIGURE( 29160 [[dependencies/C],[dependencies/D]], 29161 [], 29162 [[CPPFLAGS=-I${ac_top_srcdir}/dependencies/B -I${ac_top_builddir}/dependencies/B], 29163 [LDFLAGS=-L${ac_abs_top_builddir}/dependencies/B/.libs]], 29164 [--with-B=system], 29165 []) 29166 29167If using automake, the following can be added to the Makefile.am (we use 29168both $(subdirs) and $(subdirs_extra) since our example above used both 29169AC_CONFIG_SUBDIRS and AX_SUBDIRS_CONFIGURE): 29170 29171 SUBDIRS = $(subdirs) $(subdirs_extra) 29172 29173Source Code 29174*********** 29175 29176Download the latest version of 'ax_subdirs_configure.m4' 29177(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=blob_plain;f=m4/ax_subdirs_configure.m4) 29178or browse the macro's revision history 29179(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=history;f=m4/ax_subdirs_configure.m4). 29180 29181License 29182******* 29183 29184Copyright (C) 2017 Harenome Ranaivoarivony-Razanajato <ranaivoarivony-razanajato@hareno.me> 29185 29186This program is free software; you can redistribute it and/or modify it 29187under the terms of the GNU General Public License as published by the 29188Free Software Foundation; either version 3 of the License, or (at your 29189option) any later version. 29190 29191This program is distributed in the hope that it will be useful, but 29192WITHOUT ANY WARRANTY; without even the implied warranty of 29193MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

In other 29222words a call like AC_WITHNONE(enable-call) will create two SUBST-symbols 29223as WITH_ENABLE_CALL and WITHOUT_ENABLE_CALL.

Does AC_PATH_PROG to find 29604the path to perl. As a side-effect, that sets PERLINTERP and makes it 29605available as a substitution variable. 29606 29607Note: The macro allows for the possibility (expected to be seldom used) 29608of an explicit user override (the "user" being the operator executing 29609the final 'configure' script, in this context) by making the option 29610argument like: 29611 29612 --with-perl-shebang='#! /my/funky/perlpath' # OR 29613 --with-perl-shebang='/my/funky/perlpath' # we just throw away the #! anyway 29614 # bec it must be absent in Makefile 29615 29616Rationale: The are various ways of starting an interpreter on different 29617*nix-like systems. Many use the simple 29618 29619 #!/usr/bin/perl 29620 29621but it could be instead 29622 29623 #!/usr/local/bin/perl 29624 29625and there is even the possibility that the user wants 29626 29627 #!/usr/bin/env perl 29628 29629to find whichever perl comes first in the current $PATH. This is 29630preferred by some of us because we run multiple perl installations on 29631the same box. Adjusting our $PATH then allows us to set precedence over 29632other perls, even whatever the "house" version is. 29633 29634Users on very non-unix systems like MS Windows do not have a kernel that 29635does this kind of thing from the first line of script files, but instead 29636the perl on their machine is started and merely notices whatever comes 29637after the interpreter path on this first line of the script (options 29638like "-w"). 29639 29640Acknowledgement: this macro was in part inspired by Dean Povey's 29641AC_PROG_PERL_VERSION. 29642 29643Source Code 29644*********** 29645 29646Download the latest version of 'ax_sys_perlsharpbang.m4' 29647(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=blob_plain;f=m4/ax_sys_perlsharpbang.m4) 29648or browse the macro's revision history 29649(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=history;f=m4/ax_sys_perlsharpbang.m4). 29650 29651License 29652******* 29653 29654Copyright (C) 2009 Soren Andersen <somian@pobox.com> 29655 29656Copying and distribution of this file, with or without modification, are 29657permitted in any medium without royalty provided the copyright notice 29658and this notice are preserved.

Also checks to see if aliases can 29677cross object file boundaries, as some systems don't permit them to. 29678 29679Most systems permit something called a "weak alias" or "weak symbol." 29680These aliases permit a library to provide a stub form of a routine 29681defined in another library, thus allowing the first library to operate 29682even if the other library is not linked. This macro will check for 29683support of weak aliases, figure out what schemes are available, and 29684determine some characteristics of the weak alias support - primarily, 29685whether a weak alias declared in one object file may be referenced from 29686another object file. 29687 29688There are four known schemes of declaring weak symbols; each scheme is 29689checked in turn, and the first one found is preferred. Note that only 29690one of the mentioned preprocessor macros will be defined! 29691 296921. Function attributes 29693 29694This scheme was first introduced by the GNU C compiler, and attaches 29695attributes to particular functions. It is among the easiest to use, and 29696so is the first one checked. If this scheme is detected, the 29697preprocessor macro HAVE_SYS_WEAK_ALIAS_ATTRIBUTE will be defined to 1. 29698This scheme is used as in the following code fragment: 29699 29700 void __weakf(int c) 29701 { 29702 /* Function definition... */ 29703 } 29704 29705 void weakf(int c) __attribute__((weak, alias("__weakf"))); 29706 297072. #pragma weak 29708 29709This scheme is in use by many compilers other than the GNU C compiler. 29710It is also particularly easy to use, and fairly portable - well, as 29711portable as these things get. If this scheme is detected first, the 29712preprocessor macro HAVE_SYS_WEAK_ALIAS_PRAGMA will be defined to 1. 29713This scheme is used as in the following code fragment: 29714 29715 extern void weakf(int c); 29716 #pragma weak weakf = __weakf 29717 void __weakf(int c) 29718 { 29719 /* Function definition... */ 29720 } 29721 297223. #pragma _HP_SECONDARY_DEF 29723 29724This scheme appears to be in use by the HP compiler. As it is rather 29725specialized, this is one of the last schemes checked. If it is the 29726first one detected, the preprocessor macro 29727HAVE_SYS_WEAK_ALIAS_HPSECONDARY will be defined to 1. This scheme is 29728used as in the following code fragment: 29729 29730 extern void weakf(int c); 29731 #pragma _HP_SECONDARY_DEF __weakf weakf 29732 void __weakf(int c) 29733 { 29734 /* Function definition... */ 29735 } 29736 297374. #pragma _CRI duplicate 29738 29739This scheme appears to be in use by the Cray compiler. As it is rather 29740specialized, it too is one of the last schemes checked. If it is the 29741first one detected, the preprocessor macro 29742HAVE_SYS_WEAK_ALIAS_CRIDUPLICATE will be defined to 1. This scheme is 29743used as in the following code fragment: 29744 29745 extern void weakf(int c); 29746 #pragma _CRI duplicate weakf as __weakf 29747 void __weakf(int c) 29748 { 29749 /* Function definition... */ 29750 } 29751 29752In addition to the preprocessor macros listed above, if any scheme is 29753found, the preprocessor macro HAVE_SYS_WEAK_ALIAS will also be defined 29754to 1. 29755 29756Once a weak aliasing scheme has been found, a check will be performed to 29757see if weak aliases are honored across object file boundaries. If they 29758are, the HAVE_SYS_WEAK_ALIAS_CROSSFILE preprocessor macro is defined to 297591. 29760 29761This Autoconf macro also makes two substitutions. The first, 29762WEAK_ALIAS, contains the name of the scheme found (one of "attribute", 29763"pragma", "hpsecondary", or "criduplicate"), or "no" if no weak aliasing 29764scheme was found. The second, WEAK_ALIAS_CROSSFILE, is set to "yes" or 29765"no" depending on whether or not weak aliases may cross object file 29766boundaries. 29767 29768Source Code 29769*********** 29770 29771Download the latest version of 'ax_sys_weak_alias.m4' 29772(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=blob_plain;f=m4/ax_sys_weak_alias.m4) 29773or browse the macro's revision history 29774(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=history;f=m4/ax_sys_weak_alias.m4). 29775 29776License 29777******* 29778 29779Copyright (C) 2008 Kevin L.

VALGRIND_ENABLED is defined and substituted, and corresponds to 30619the value of the -enable-valgrind option, which defaults to being 30620enabled if Valgrind is installed and disabled otherwise. Individual 30621Valgrind tools can be disabled via -disable-valgrind-<tool>, the default 30622is configurable via the AX_VALGRIND_DFLT command or is to use all 30623commands not disabled via AX_VALGRIND_DFLT. All AX_VALGRIND_DFLT calls 30624must be made before the call to AX_VALGRIND_CHECK. 30625 30626If unit tests are written using a shell script and automake's 30627LOG_COMPILER system, the $(VALGRIND) variable can be used within the 30628shell scripts to enable Valgrind, as described here: 30629 30630 https://www.gnu.org/software/gnulib/manual/html_node/Running-self_002dtests-under-valgrind.html 30631 30632Usage example: 30633 30634configure.ac: 30635 30636 AX_VALGRIND_DFLT([sgcheck], [off]) 30637 AX_VALGRIND_CHECK 30638 30639in each Makefile.am with tests: 30640 30641 @VALGRIND_CHECK_RULES@ 30642 VALGRIND_SUPPRESSIONS_FILES = my-project.supp 30643 EXTRA_DIST = my-project.supp 30644 30645This results in a "check-valgrind" rule being added. Running 'make 30646check-valgrind' in that directory will recursively run the module's test 30647suite ('make check') once for each of the available Valgrind tools (out 30648of memcheck, helgrind and drd) while the sgcheck will be skipped unless 30649enabled again on the commandline with -enable-valgrind-sgcheck. The 30650results for each check will be output to test-suite-$toolname.log. The 30651target will succeed if there are zero errors and fail otherwise. 30652 30653Alternatively, a "check-valgrind-$TOOL" rule will be added, for $TOOL in 30654memcheck, helgrind, drd and sgcheck. These are useful because often 30655only some of those tools can be ran cleanly on a codebase. 30656 30657The macro supports running with and without libtool. 30658 30659Source Code 30660*********** 30661 30662Download the latest version of 'ax_valgrind_check.m4' 30663(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=blob_plain;f=m4/ax_valgrind_check.m4) 30664or browse the macro's revision history 30665(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=history;f=m4/ax_valgrind_check.m4). 30666 30667License 30668******* 30669 30670Copyright (C) 2014, 2015, 2016 Philip Withnall <philip.withnall@collabora.co.uk> 30671 30672Copying and distribution of this file, with or without modification, are 30673permitted in any medium without royalty provided the copyright notice 30674and this notice are preserved.

The NcursesW 31198(wide-character) library is searched for first, followed by Ncurses, 31199then the system-default plain Curses. The first library found is the 31200one returned. Finding libraries will first be attempted by using 31201pkg-config, and should the pkg-config files not be available, will 31202fallback to combinations of known flags itself. 31203 31204The following options are understood: -with-ncursesw, -with-ncurses, 31205-without-ncursesw, -without-ncurses. The "-with" options force the 31206macro to use that particular library, terminating with an error if not 31207found. The "-without" options simply skip the check for that library. 31208The effect on the search pattern is: 31209 31210 (no options) - NcursesW, Ncurses, Curses 31211 --with-ncurses --with-ncursesw - NcursesW only [*] 31212 --without-ncurses --with-ncursesw - NcursesW only [*] 31213 --with-ncursesw - NcursesW only [*] 31214 --with-ncurses --without-ncursesw - Ncurses only [*] 31215 --with-ncurses - NcursesW, Ncurses [**] 31216 --without-ncurses --without-ncursesw - Curses only 31217 --without-ncursesw - Ncurses, Curses 31218 --without-ncurses - NcursesW, Curses 31219 31220[*] If the library is not found, abort the configure script. 31221 31222[**] If the second library (Ncurses) is not found, abort configure. 31223 31224The following preprocessor symbols may be defined by this macro if the 31225appropriate conditions are met: 31226 31227 HAVE_CURSES - if any SysV or X/Open Curses library found 31228 HAVE_CURSES_ENHANCED - if library supports X/Open Enhanced functions 31229 HAVE_CURSES_COLOR - if library supports color (enhanced functions) 31230 HAVE_CURSES_OBSOLETE - if library supports certain obsolete features 31231 HAVE_NCURSESW - if NcursesW (wide char) library is to be used 31232 HAVE_NCURSES - if the Ncurses library is to be used 31233 31234 HAVE_CURSES_H - if <curses.h> is present and should be used 31235 HAVE_NCURSESW_H - if <ncursesw.h> should be used 31236 HAVE_NCURSES_H - if <ncurses.h> should be used 31237 HAVE_NCURSESW_CURSES_H - if <ncursesw/curses.h> should be used 31238 HAVE_NCURSES_CURSES_H - if <ncurses/curses.h> should be used 31239 31240(These preprocessor symbols are discussed later in this document.) 31241 31242The following output variables are defined by this macro; they are 31243precious and may be overridden on the ./configure command line: 31244 31245 CURSES_LIBS - library to add to xxx_LDADD 31246 CURSES_CFLAGS - include paths to add to xxx_CPPFLAGS 31247 31248In previous versions of this macro, the flags CURSES_LIB and 31249CURSES_CPPFLAGS were defined. These have been renamed, in keeping with 31250AX_WITH_CURSES's close bigger brother, PKG_CHECK_MODULES, which should 31251eventually supersede the use of AX_WITH_CURSES. Neither the library 31252listed in CURSES_LIBS, nor the flags in CURSES_CFLAGS are added to LIBS, 31253respectively CPPFLAGS, by default. You need to add both to the 31254appropriate xxx_LDADD/xxx_CPPFLAGS line in your Makefile.am. For 31255example: 31256 31257 prog_LDADD = @CURSES_LIBS@ 31258 prog_CPPFLAGS = @CURSES_CFLAGS@ 31259 31260If CURSES_LIBS is set on the configure command line (such as by running 31261"./configure CURSES_LIBS=-lmycurses"), then the only header searched for 31262is <curses.h>. If the user needs to specify an alternative path for a 31263library (such as for a non-standard NcurseW), the user should use the 31264LDFLAGS variable. 31265 31266The following shell variables may be defined by this macro: 31267 31268 ax_cv_curses - set to "yes" if any Curses library found 31269 ax_cv_curses_enhanced - set to "yes" if Enhanced functions present 31270 ax_cv_curses_color - set to "yes" if color functions present 31271 ax_cv_curses_obsolete - set to "yes" if obsolete features present 31272 31273 ax_cv_ncursesw - set to "yes" if NcursesW library found 31274 ax_cv_ncurses - set to "yes" if Ncurses library found 31275 ax_cv_plaincurses - set to "yes" if plain Curses library found 31276 ax_cv_curses_which - set to "ncursesw", "ncurses", "plaincurses" or "no" 31277 31278These variables can be used in your configure.ac to determine the level 31279of support you need from the Curses library. For example, if you must 31280have either Ncurses or NcursesW, you could include: 31281 31282 AX_WITH_CURSES 31283 if test "x$ax_cv_ncursesw" != xyes && test "x$ax_cv_ncurses" != xyes; then 31284 AC_MSG_ERROR([requires either NcursesW or Ncurses library]) 31285 fi 31286 31287If any Curses library will do (but one must be present and must support 31288color), you could use: 31289 31290 AX_WITH_CURSES 31291 if test "x$ax_cv_curses" != xyes || test "x$ax_cv_curses_color" != xyes; then 31292 AC_MSG_ERROR([requires an X/Open-compatible Curses library with color]) 31293 fi 31294 31295Certain preprocessor symbols and shell variables defined by this macro 31296can be used to determine various features of the Curses library. In 31297particular, HAVE_CURSES and ax_cv_curses are defined if the Curses 31298library found conforms to the traditional SysV and/or X/Open Base Curses 31299definition. Any working Curses library conforms to this level. 31300 31301HAVE_CURSES_ENHANCED and ax_cv_curses_enhanced are defined if the 31302library supports the X/Open Enhanced Curses definition. In particular, 31303the wide-character types attr_t, cchar_t and wint_t, the functions 31304wattr_set() and wget_wch() and the macros WA_NORMAL and _XOPEN_CURSES 31305are checked. The Ncurses library does NOT conform to this definition, 31306although NcursesW does. 31307 31308HAVE_CURSES_COLOR and ax_cv_curses_color are defined if the library 31309supports color functions and macros such as COLOR_PAIR, A_COLOR, 31310COLOR_WHITE, COLOR_RED and init_pair(). These are NOT part of the 31311X/Open Base Curses definition, but are part of the Enhanced set of 31312functions. The Ncurses library DOES support these functions, as does 31313NcursesW. 31314 31315HAVE_CURSES_OBSOLETE and ax_cv_curses_obsolete are defined if the 31316library supports certain features present in SysV and BSD Curses but not 31317defined in the X/Open definition. In particular, the functions 31318getattrs(), getcurx() and getmaxx() are checked. 31319 31320To use the HAVE_xxx_H preprocessor symbols, insert the following into 31321your system.h (or equivalent) header file: 31322 31323 #if defined HAVE_NCURSESW_CURSES_H 31324 # include <ncursesw/curses.h> 31325 #elif defined HAVE_NCURSESW_H 31326 # include <ncursesw.h> 31327 #elif defined HAVE_NCURSES_CURSES_H 31328 # include <ncurses/curses.h> 31329 #elif defined HAVE_NCURSES_H 31330 # include <ncurses.h> 31331 #elif defined HAVE_CURSES_H 31332 # include <curses.h> 31333 #else 31334 # error "SysV or X/Open-compatible Curses header file required" 31335 #endif 31336 31337For previous users of this macro: you should not need to change anything 31338in your configure.ac or Makefile.am, as the previous (serial 10) 31339semantics are still valid. However, you should update your system.h (or 31340equivalent) header file to the fragment shown above. You are encouraged 31341also to make use of the extended functionality provided by this version 31342of AX_WITH_CURSES, as well as in the additional macros 31343AX_WITH_CURSES_PANEL, AX_WITH_CURSES_MENU and AX_WITH_CURSES_FORM. 31344 31345Source Code 31346*********** 31347 31348Download the latest version of 'ax_with_curses.m4' 31349(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=blob_plain;f=m4/ax_with_curses.m4) 31350or browse the macro's revision history 31351(http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=history;f=m4/ax_with_curses.m4). 31352 31353License 31354******* 31355 31356Copyright (C) 2009 Mark Pulford <mark@kyne.com.au> 31357Copyright (C) 2009 Damian Pietras <daper@daper.net> 31358Copyright (C) 2012 Reuben Thomas <rrt@sc3d.org> 31359Copyright (C) 2011 John Zaitseff <J.Zaitseff@zap.org.au> 31360 31361This program is free software: you can redistribute it and/or modify it 31362under the terms of the GNU General Public License as published by the 31363Free Software Foundation, either version 3 of the License, or (at your 31364option) any later version. 31365 31366This program is distributed in the hope that it will be useful, but 31367WITHOUT ANY WARRANTY; without even the implied warranty of 31368MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

In particular, the Panel, Menu and Form 31405libraries are searched, along with their header files. These macros 31406depend on AX_WITH_CURSES. 31407 31408The following preprocessor symbols may be defined by these macros: 31409 31410 By AX_WITH_CURSES_PANEL: 31411 31412 HAVE_PANEL - if the Panel library is present 31413 HAVE_PANEL_H - if <panel.h> is present and should be used 31414 HAVE_NCURSES_PANEL_H - if <ncurses/panel.h> should be used 31415 HAVE_NCURSESW_PANEL_H - if <ncursesw/panel.h> should be used 31416 31417 By AX_WITH_CURSES_MENU: 31418 31419 HAVE_MENU - if the Menu library is present 31420 HAVE_MENU_H - if <menu.h> is present and should be used 31421 HAVE_NCURSES_MENU_H - if <ncurses/menu.h> should be used 31422 HAVE_NCURSESW_MENU_H - if <ncursesw/menu.h> should be used 31423 31424 By AX_WITH_CURSES_FORM: 31425 31426 HAVE_FORM - if the Form library is present 31427 HAVE_FORM_H - if <form.h> is present and should be used 31428 HAVE_NCURSES_FORM_H - if <ncurses/form.h> should be used 31429 HAVE_NCURSESW_FORM_H - if <ncursesw/form.h> should be used 31430 31431The following output variables may be defined by these macros; these are 31432precious and may be overridden on the ./configure command line: 31433 31434 PANEL_LIBS - library to add to xxx_LDADD before CURSES_LIBS 31435 MENU_LIBS - library to add to xxx_LDADD before CURSES_LIBS 31436 FORM_LIBS - library to add to xxx_LDADD before CURSES_LIBS 31437 31438In previous versions of this macro, the flags PANEL_LIB, MENU_LIB and 31439FORM_LIB were defined. These have been renamed, in keeping with the 31440variable scheme of PKG_CHECK_MODULES, which should eventually supersede 31441the use of AX_WITH_CURSES and AX_WITH_CURSES_* macros. These libraries 31442are NOT added to LIBS by default. You need to add them to the 31443appropriate xxx_LDADD line in your Makefile.am in front of the 31444equivalent CURSES_LIBS incantation. For example: 31445 31446 prog_LDADD = @PANEL_LIBS@ @CURSES_LIBS@ 31447 31448If one of the xxx_LIBS variables is set on the configure command line 31449(such as by running "./configure PANEL_LIBS=-lmypanel"), then the header 31450file searched must NOT contain a subpath.

You accept 31997 the license if you copy, modify or distribute the work in a way 31998 requiring permission under copyright law. 31999 32000 A "Modified Version" of the Document means any work containing the 32001 Document or a portion of it, either copied verbatim, or with 32002 modifications and/or translated into another language. 32003 32004 A "Secondary Section" is a named appendix or a front-matter section 32005 of the Document that deals exclusively with the relationship of the 32006 publishers or authors of the Document to the Document's overall 32007 subject (or to related matters) and contains nothing that could 32008 fall directly within that overall subject. (Thus, if the Document 32009 is in part a textbook of mathematics, a Secondary Section may not 32010 explain any mathematics.) The relationship could be a matter of 32011 historical connection with the subject or with related matters, or 32012 of legal, commercial, philosophical, ethical or political position 32013 regarding them. 32014 32015 The "Invariant Sections" are certain Secondary Sections whose 32016 titles are designated, as being those of Invariant Sections, in the 32017 notice that says that the Document is released under this License. 32018 If a section does not fit the above definition of Secondary then it 32019 is not allowed to be designated as Invariant. The Document may 32020 contain zero Invariant Sections. If the Document does not identify 32021 any Invariant Sections then there are none. 32022 32023 The "Cover Texts" are certain short passages of text that are 32024 listed, as Front-Cover Texts or Back-Cover Texts, in the notice 32025 that says that the Document is released under this License. A 32026 Front-Cover Text may be at most 5 words, and a Back-Cover Text may 32027 be at most 25 words. 32028 32029 A "Transparent" copy of the Document means a machine-readable copy, 32030 represented in a format whose specification is available to the 32031 general public, that is suitable for revising the document 32032 straightforwardly with generic text editors or (for images composed 32033 of pixels) generic paint programs or (for drawings) some widely 32034 available drawing editor, and that is suitable for input to text 32035 formatters or for automatic translation to a variety of formats 32036 suitable for input to text formatters. A copy made in an otherwise 32037 Transparent file format whose markup, or absence of markup, has 32038 been arranged to thwart or discourage subsequent modification by 32039 readers is not Transparent. An image format is not Transparent if 32040 used for any substantial amount of text. A copy that is not 32041 "Transparent" is called "Opaque". 32042 32043 Examples of suitable formats for Transparent copies include plain 32044 ASCII without markup, Texinfo input format, LaTeX input format, 32045 SGML or XML using a publicly available DTD, and standard-conforming 32046 simple HTML, PostScript or PDF designed for human modification. 32047 Examples of transparent image formats include PNG, XCF and JPG. 32048 Opaque formats include proprietary formats that can be read and 32049 edited only by proprietary word processors, SGML or XML for which 32050 the DTD and/or processing tools are not generally available, and 32051 the machine-generated HTML, PostScript or PDF produced by some word 32052 processors for output purposes only. 32053 32054 The "Title Page" means, for a printed book, the title page itself, 32055 plus such following pages as are needed to hold, legibly, the 32056 material this License requires to appear in the title page. For 32057 works in formats which do not have any title page as such, "Title 32058 Page" means the text near the most prominent appearance of the 32059 work's title, preceding the beginning of the body of the text. 32060 32061 The "publisher" means any person or entity that distributes copies 32062 of the Document to the public. 32063 32064 A section "Entitled XYZ" means a named subunit of the Document 32065 whose title either is precisely XYZ or contains XYZ in parentheses 32066 following text that translates XYZ in another language. (Here XYZ 32067 stands for a specific section name mentioned below, such as 32068 "Acknowledgements", "Dedications", "Endorsements", or "History".) 32069 To "Preserve the Title" of such a section when you modify the 32070 Document means that it remains a section "Entitled XYZ" according 32071 to this definition. 32072 32073 The Document may include Warranty Disclaimers next to the notice 32074 which states that this License applies to the Document. These 32075 Warranty Disclaimers are considered to be included by reference in 32076 this License, but only as regards disclaiming warranties: any other 32077 implication that these Warranty Disclaimers may have is void and 32078 has no effect on the meaning of this License. 32079 32080 2. VERBATIM COPYING 32081 32082 You may copy and distribute the Document in any medium, either 32083 commercially or noncommercially, provided that this License, the 32084 copyright notices, and the license notice saying this License 32085 applies to the Document are reproduced in all copies, and that you 32086 add no other conditions whatsoever to those of this License. You 32087 may not use technical measures to obstruct or control the reading 32088 or further copying of the copies you make or distribute. However, 32089 you may accept compensation in exchange for copies. If you 32090 distribute a large enough number of copies you must also follow the 32091 conditions in section 3. 32092 32093 You may also lend copies, under the same conditions stated above, 32094 and you may publicly display copies. 32095 32096 3. COPYING IN QUANTITY 32097 32098 If you publish printed copies (or copies in media that commonly 32099 have printed covers) of the Document, numbering more than 100, and 32100 the Document's license notice requires Cover Texts, you must 32101 enclose the copies in covers that carry, clearly and legibly, all 32102 these Cover Texts: Front-Cover Texts on the front cover, and 32103 Back-Cover Texts on the back cover. Both covers must also clearly 32104 and legibly identify you as the publisher of these copies. The 32105 front cover must present the full title with all words of the title 32106 equally prominent and visible. You may add other material on the 32107 covers in addition. Copying with changes limited to the covers, as 32108 long as they preserve the title of the Document and satisfy these 32109 conditions, can be treated as verbatim copying in other respects. 32110 32111 If the required texts for either cover are too voluminous to fit 32112 legibly, you should put the first ones listed (as many as fit 32113 reasonably) on the actual cover, and continue the rest onto 32114 adjacent pages. 32115 32116 If you publish or distribute Opaque copies of the Document 32117 numbering more than 100, you must either include a machine-readable 32118 Transparent copy along with each Opaque copy, or state in or with 32119 each Opaque copy a computer-network location from which the general 32120 network-using public has access to download using public-standard 32121 network protocols a complete Transparent copy of the Document, free 32122 of added material. If you use the latter option, you must take 32123 reasonably prudent steps, when you begin distribution of Opaque 32124 copies in quantity, to ensure that this Transparent copy will 32125 remain thus accessible at the stated location until at least one 32126 year after the last time you distribute an Opaque copy (directly or 32127 through your agents or retailers) of that edition to the public. 32128 32129 It is requested, but not required, that you contact the authors of 32130 the Document well before redistributing any large number of copies, 32131 to give them a chance to provide you with an updated version of the 32132 Document. 32133 32134 4. MODIFICATIONS 32135 32136 You may copy and distribute a Modified Version of the Document 32137 under the conditions of sections 2 and 3 above, provided that you 32138 release the Modified Version under precisely this License, with the 32139 Modified Version filling the role of the Document, thus licensing 32140 distribution and modification of the Modified Version to whoever 32141 possesses a copy of it. In addition, you must do these things in 32142 the Modified Version: 32143 32144 A. Use in the Title Page (and on the covers, if any) a title 32145 distinct from that of the Document, and from those of previous 32146 versions (which should, if there were any, be listed in the 32147 History section of the Document). You may use the same title 32148 as a previous version if the original publisher of that 32149 version gives permission. 32150 32151 B. List on the Title Page, as authors, one or more persons or 32152 entities responsible for authorship of the modifications in 32153 the Modified Version, together with at least five of the 32154 principal authors of the Document (all of its principal 32155 authors, if it has fewer than five), unless they release you 32156 from this requirement. 32157 32158 C. State on the Title page the name of the publisher of the 32159 Modified Version, as the publisher. 32160 32161 D. Preserve all the copyright notices of the Document. 32162 32163 E. Add an appropriate copyright notice for your modifications 32164 adjacent to the other copyright notices. 32165 32166 F. Include, immediately after the copyright notices, a license 32167 notice giving the public permission to use the Modified 32168 Version under the terms of this License, in the form shown in 32169 the Addendum below. 32170 32171 G. Preserve in that license notice the full lists of Invariant 32172 Sections and required Cover Texts given in the Document's 32173 license notice. 32174 32175 H. Include an unaltered copy of this License. 32176 32177 I. Preserve the section Entitled "History", Preserve its Title, 32178 and add to it an item stating at least the title, year, new 32179 authors, and publisher of the Modified Version as given on the 32180 Title Page. If there is no section Entitled "History" in the 32181 Document, create one stating the title, year, authors, and 32182 publisher of the Document as given on its Title Page, then add 32183 an item describing the Modified Version as stated in the 32184 previous sentence. 32185 32186 J. Preserve the network location, if any, given in the Document 32187 for public access to a Transparent copy of the Document, and 32188 likewise the network locations given in the Document for 32189 previous versions it was based on. These may be placed in the 32190 "History" section. You may omit a network location for a work 32191 that was published at least four years before the Document 32192 itself, or if the original publisher of the version it refers 32193 to gives permission. 32194 32195 K. For any section Entitled "Acknowledgements" or "Dedications", 32196 Preserve the Title of the section, and preserve in the section 32197 all the substance and tone of each of the contributor 32198 acknowledgements and/or dedications given therein. 32199 32200 L. Preserve all the Invariant Sections of the Document, unaltered 32201 in their text and in their titles. Section numbers or the 32202 equivalent are not considered part of the section titles. 32203 32204 M. Delete any section Entitled "Endorsements". Such a section 32205 may not be included in the Modified Version. 32206 32207 N. Do not retitle any existing section to be Entitled 32208 "Endorsements" or to conflict in title with any Invariant 32209 Section. 32210 32211 O. Preserve any Warranty Disclaimers. 32212 32213 If the Modified Version includes new front-matter sections or 32214 appendices that qualify as Secondary Sections and contain no 32215 material copied from the Document, you may at your option designate 32216 some or all of these sections as invariant. To do this, add their 32217 titles to the list of Invariant Sections in the Modified Version's 32218 license notice. These titles must be distinct from any other 32219 section titles. 32220 32221 You may add a section Entitled "Endorsements", provided it contains 32222 nothing but endorsements of your Modified Version by various 32223 parties--for example, statements of peer review or that the text 32224 has been approved by an organization as the authoritative 32225 definition of a standard. 32226 32227 You may add a passage of up to five words as a Front-Cover Text, 32228 and a passage of up to 25 words as a Back-Cover Text, to the end of 32229 the list of Cover Texts in the Modified Version. Only one passage 32230 of Front-Cover Text and one of Back-Cover Text may be added by (or 32231 through arrangements made by) any one entity. If the Document 32232 already includes a cover text for the same cover, previously added 32233 by you or by arrangement made by the same entity you are acting on 32234 behalf of, you may not add another; but you may replace the old 32235 one, on explicit permission from the previous publisher that added 32236 the old one. 32237 32238 The author(s) and publisher(s) of the Document do not by this 32239 License give permission to use their names for publicity for or to 32240 assert or imply endorsement of any Modified Version. 32241 32242 5. COMBINING DOCUMENTS 32243 32244 You may combine the Document with other documents released under 32245 this License, under the terms defined in section 4 above for 32246 modified versions, provided that you include in the combination all 32247 of the Invariant Sections of all of the original documents, 32248 unmodified, and list them all as Invariant Sections of your 32249 combined work in its license notice, and that you preserve all 32250 their Warranty Disclaimers. 32251 32252 The combined work need only contain one copy of this License, and 32253 multiple identical Invariant Sections may be replaced with a single 32254 copy. If there are multiple Invariant Sections with the same name 32255 but different contents, make the title of each such section unique 32256 by adding at the end of it, in parentheses, the name of the 32257 original author or publisher of that section if known, or else a 32258 unique number. Make the same adjustment to the section titles in 32259 the list of Invariant Sections in the license notice of the 32260 combined work. 32261 32262 In the combination, you must combine any sections Entitled 32263 "History" in the various original documents, forming one section 32264 Entitled "History"; likewise combine any sections Entitled 32265 "Acknowledgements", and any sections Entitled "Dedications". You 32266 must delete all sections Entitled "Endorsements." 32267 32268 6. COLLECTIONS OF DOCUMENTS 32269 32270 You may make a collection consisting of the Document and other 32271 documents released under this License, and replace the individual 32272 copies of this License in the various documents with a single copy 32273 that is included in the collection, provided that you follow the 32274 rules of this License for verbatim copying of each of the documents 32275 in all other respects. 32276 32277 You may extract a single document from such a collection, and 32278 distribute it individually under this License, provided you insert 32279 a copy of this License into the extracted document, and follow this 32280 License in all other respects regarding verbatim copying of that 32281 document. 32282 32283 7. AGGREGATION WITH INDEPENDENT WORKS 32284 32285 A compilation of the Document or its derivatives with other 32286 separate and independent documents or works, in or on a volume of a 32287 storage or distribution medium, is called an "aggregate" if the 32288 copyright resulting from the compilation is not used to limit the 32289 legal rights of the compilation's users beyond what the individual 32290 works permit. When the Document is included in an aggregate, this 32291 License does not apply to the other works in the aggregate which 32292 are not themselves derivative works of the Document. 32293 32294 If the Cover Text requirement of section 3 is applicable to these 32295 copies of the Document, then if the Document is less than one half 32296 of the entire aggregate, the Document's Cover Texts may be placed 32297 on covers that bracket the Document within the aggregate, or the 32298 electronic equivalent of covers if the Document is in electronic 32299 form. Otherwise they must appear on printed covers that bracket 32300 the whole aggregate. 32301 32302 8. TRANSLATION 32303 32304 Translation is considered a kind of modification, so you may 32305 distribute translations of the Document under the terms of section 32306 4. Replacing Invariant Sections with translations requires special 32307 permission from their copyright holders, but you may include 32308 translations of some or all Invariant Sections in addition to the 32309 original versions of these Invariant Sections. You may include a 32310 translation of this License, and all the license notices in the 32311 Document, and any Warranty Disclaimers, provided that you also 32312 include the original English version of this License and the 32313 original versions of those notices and disclaimers. In case of a 32314 disagreement between the translation and the original version of 32315 this License or a notice or disclaimer, the original version will 32316 prevail. 32317 32318 If a section in the Document is Entitled "Acknowledgements", 32319 "Dedications", or "History", the requirement (section 4) to 32320 Preserve its Title (section 1) will typically require changing the 32321 actual title. 32322 32323 9. TERMINATION 32324 32325 You may not copy, modify, sublicense, or distribute the Document 32326 except as expressly provided under this License. Any attempt 32327 otherwise to copy, modify, sublicense, or distribute it is void, 32328 and will automatically terminate your rights under this License. 32329 32330 However, if you cease all violation of this License, then your 32331 license from a particular copyright holder is reinstated (a) 32332 provisionally, unless and until the copyright holder explicitly and 32333 finally terminates your license, and (b) permanently, if the 32334 copyright holder fails to notify you of the violation by some 32335 reasonable means prior to 60 days after the cessation. 32336 32337 Moreover, your license from a particular copyright holder is 32338 reinstated permanently if the copyright holder notifies you of the 32339 violation by some reasonable means, this is the first time you have 32340 received notice of violation of this License (for any work) from 32341 that copyright holder, and you cure the violation prior to 30 days 32342 after your receipt of the notice. 32343 32344 Termination of your rights under this section does not terminate 32345 the licenses of parties who have received copies or rights from you 32346 under this License. If your rights have been terminated and not 32347 permanently reinstated, receipt of a copy of some or all of the 32348 same material does not give you any rights to use it. 32349 32350 10. FUTURE REVISIONS OF THIS LICENSE 32351 32352 The Free Software Foundation may publish new, revised versions of 32353 the GNU Free Documentation License from time to time. Such new 32354 versions will be similar in spirit to the present version, but may 32355 differ in detail to address new problems or concerns. See 32356 <https://www.gnu.org/licenses/>. 32357 32358 Each version of the License is given a distinguishing version 32359 number. If the Document specifies that a particular numbered 32360 version of this License "or any later version" applies to it, you 32361 have the option of following the terms and conditions either of 32362 that specified version or of any later version that has been 32363 published (not as a draft) by the Free Software Foundation. If the 32364 Document does not specify a version number of this License, you may 32365 choose any version ever published (not as a draft) by the Free 32366 Software Foundation. If the Document specifies that a proxy can 32367 decide which future versions of this License can be used, that 32368 proxy's public statement of acceptance of a version permanently 32369 authorizes you to choose that version for the Document. 32370 32371 11. RELICENSING 32372 32373 "Massive Multiauthor Collaboration Site" (or "MMC Site") means any 32374 World Wide Web server that publishes copyrightable works and also 32375 provides prominent facilities for anybody to edit those works. A 32376 public wiki that anybody can edit is an example of such a server. 32377 A "Massive Multiauthor Collaboration" (or "MMC") contained in the 32378 site means any set of copyrightable works thus published on the MMC 32379 site. 32380 32381 "CC-BY-SA" means the Creative Commons Attribution-Share Alike 3.0 32382 license published by Creative Commons Corporation, a not-for-profit 32383 corporation with a principal place of business in San Francisco, 32384 California, as well as future copyleft versions of that license 32385 published by that same organization. 32386 32387 "Incorporate" means to publish or republish a Document, in whole or 32388 in part, as part of another Document. 32389 32390 An MMC is "eligible for relicensing" if it is licensed under this 32391 License, and if all works that were first published under this 32392 License somewhere other than this MMC, and subsequently 32393 incorporated in whole or in part into the MMC, (1) had no cover 32394 texts or invariant sections, and (2) were thus incorporated prior 32395 to November 1, 2008. 32396 32397 The operator of an MMC Site may republish an MMC contained in the 32398 site under CC-BY-SA on the same site at any time before August 1, 32399 2009, provided the MMC is eligible for relicensing. 32400 32401ADDENDUM: How to use this License for your documents 32402==================================================== 32403 32404To use this License in a document you have written, include a copy of 32405the License in the document and put the following copyright and license 32406notices just after the title page: 32407 32408 Copyright (C) YEAR YOUR NAME. 32409 Permission is granted to copy, distribute and/or modify this document 32410 under the terms of the GNU Free Documentation License, Version 1.3 32411 or any later version published by the Free Software Foundation; 32412 with no Invariant Sections, no Front-Cover Texts, and no Back-Cover 32413 Texts. A copy of the license is included in the section entitled ``GNU 32414 Free Documentation License''. 32415 32416If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts, 32417replace the "with...Texts." line with this: 32418 32419 with the Invariant Sections being LIST THEIR TITLES, with 32420 the Front-Cover Texts being LIST, and with the Back-Cover Texts 32421 being LIST. 32422 32423If you have Invariant Sections without Cover Texts, or some other 32424combination of the three, merge those two alternatives to suit the 32425situation. 32426 32427If your document contains nontrivial examples of program code, we 32428recommend releasing these examples in parallel under your choice of free 32429software license, such as the GNU General Public License, to permit 32430their use in free software. 32431 32432 32433 32434Tag Table: 32435Node: Top823 32436Node: Introduction1898 32437Node: Downloads3460 32438Node: How to contribute4502 32439Node: The Macros7600
