1This directory contains the %VERSION% release of GNU Make.
2
3See the file NEWS for the user-visible changes from previous releases.
4In addition, there have been bugs fixed.
5
6Please check the system-specific notes below for any caveats related to
7your operating system.
8
9For general building and installation instructions, see the file INSTALL.
10
11If you need to build GNU Make and have no other `make' program to use,
12you can use the shell script `build.sh' instead.  To do this, first run
13`configure' as described in INSTALL.  Then, instead of typing `make' to
14build the program, type `sh build.sh'.  This should compile the program
15in the current directory.  Then you will have a Make program that you can
16use for `./make install', or whatever else.
17
18Some systems' Make programs are broken and cannot process the Makefile for
19GNU Make.  If you get errors from your system's Make when building GNU
20Make, try using `build.sh' instead.

23GNU Make is free software.  See the file COPYING for copying conditions.

34Documentation
35-------------
36
37GNU make is fully documented in the GNU Make manual, which is contained
38in this distribution as the file make.texinfo.  You can also find
39on-line and preformatted (PostScript and DVI) versions at the FSF's web
40site.  There is information there about ordering hardcopy documentation.

50GNU Make development is hosted by Savannah, the FSF's online development
51management tool.  Savannah is here:

63Bug Reporting
64-------------
65
66You can send GNU make bug reports to <bug-make@gnu.org>.  Please see the
67section of the GNU make manual entitled `Problems and Bugs' for
68information on submitting useful and complete bug reports.
69
70You can also use the online bug tracking system in the Savannah GNU Make
71project to submit new problem reports or search for existing ones:

94CVS Access
95----------
96
97The GNU make source repository is available via anonymous CVS from the
98GNU Subversions CVS server; look here for details:
99
100  http://savannah.gnu.org/cvs/?group=make
101
102Please note: you won't be able to build GNU make from CVS without
103installing appropriate maintainer's tools, such as GNU m4, automake,
104autoconf, Perl, GNU make, and GCC.  See the README.cvs file for hints on
105how to build GNU make once these tools are available.  We make no
106guarantees about the contents or quality of the latest code in the CVS
107repository: it is not unheard of for code that is known to be broken to
108be checked in.  Use at your own risk.

111System-specific Notes
112---------------------
113
114It has been reported that the XLC 1.2 compiler on AIX 3.2 is buggy such
115that if you compile make with `cc -O' on AIX 3.2, it will not work
116correctly.  It is said that using `cc' without `-O' does work.
117
118The standard /bin/sh on SunOS 4.1.3_U1 and 4.1.4 is broken and cannot be
119used to configure GNU make.  Please install a different shell such as
120bash or pdksh in order to run "configure".  See this message for more
121information:
122  http://mail.gnu.org/archive/html/bug-autoconf/2003-10/msg00190.html
123
124One area that is often a problem in configuration and porting is the code
125to check the system's current load average.  To make it easier to test and
126debug this code, you can do `make check-loadavg' to see if it works
127properly on your system.  (You must run `configure' beforehand, but you
128need not build Make itself to run this test.)
129
130Another potential source of porting problems is the support for large
131files (LFS) in configure for those operating systems that provide it.
132Please report any bugs that you find in this area.  If you run into
133difficulties, then as a workaround you should be able to disable LFS by
134adding the `--disable-largefile' option to the `configure' script.
135
136On systems that support micro- and nano-second timestamp values and
137where stat(2) provides this information, GNU make will use it when
138comparing timestamps to get the most accurate possible result.  However,
139note that many current implementations of tools that *set* timestamps do
140not preserve micro- or nano-second granularity.  This means that "cp -p"
141and other similar tools (tar, etc.) may not exactly duplicate timestamps
142with micro- and nano-second granularity on some systems.  If your build
143system contains rules that depend on proper behavior of tools like "cp
144-p", you should consider using the .LOW_RESOLUTION_TIME pseudo-target to
145force make to treat them properly.  See the manual for details.

148Ports
149-----
150
151  - See README.customs for details on integrating GNU make with the
152    Customs distributed build environment from the Pmake distribution.
153
154  - See readme.vms for details about GNU Make on OpenVMS.
155

157
158  - See README.W32 for details about GNU Make on Windows NT, 95, or 98.
159
160  - See README.DOS for compilation instructions on MS-DOS and MS-Windows
161    using DJGPP tools.
162
163    A precompiled binary of the MSDOS port of GNU Make is available as part
164    of DJGPP; see the WWW page http://www.delorie.com/djgpp/ for more
165    information.
166
167Please note there are two _separate_ ports of GNU make for Microsoft
168systems: a native Windows tool built with (for example) MSVC or Cygwin,
169and a DOS-based tool built with DJGPP.  Please be sure you are looking
170at the right README!
