README
1These files are used by a program called aclocal (part of the GNU
2automake package) which uses them to create aclocal.m4 which is in turn
3used by autoconf to create the configure script at the the top level in
4this distribution.
5
6(Actually, as we need to change a few `standard' macros, we need to
7create acinclude.m4 by concatenating all m4 files in this directory
8before running aclocal.)
9
10The files are as follows.
11
12 R.m4
13 contains R specific macros. Some of these might be useful for
14 other systems as well, but we first need to split this into
15 pieces.
16 R_BLAS_LIBS is based on the AC_ARG_WITH(fastblas) code from
17 Octave, but with tests for Alpha CXML/DXML and IRIX SCSL and
18 SGIMATH libraries commented out.
19 Some macros do not conform to the Autoconf $PKG_$CATEGORY_$FOO
20 naming scheme. These test for `features' such as GNOME, zlib,
21 etc., are named R_$FEATURE, and typically define HAVE_$FEATURE.
22
23 clibs.m4
24 versions of the autoconf macros to find the Fortran libraries
25 amended to find the C libraries (for comparison with the Fortran
26 ones).
27
28 codeset.m4
29 is from GNU gettext and checks whether nl_langinfo(CODESET)
30 is available in langinfo.h.
31
32 gettext.m4
33 a concatenation of all the required files from gettext 0.14.5
34 except codeset.m4.
35
36 gettext-lib.m4
37 a concatenation of the m4 files from gettext-0.14.5/autoconf-lib-link.
38
39 libtool.m4
40 is from libtool 1.5.6.
