| These files are used by a program called aclocal (part of the GNU | |
| automake package) which uses them to create aclocal.m4 which is in turn | |
| used by autoconf to create the configure script at the the top level in | |
| this distribution. | |
| (Actually, as we need to change a few `standard' macros, we need to | |
| create acinclude.m4 by concatenating all m4 files in this directory | |
| before running aclocal.) | |
| The files are as follows. | |
| R.m4 | |
| contains R specific macros. Some of these might be useful for | |
| other systems as well, but we first need to split this into | |
| pieces. | |
| R_BLAS_LIBS is based on the AC_ARG_WITH(fastblas) code from | |
| Octave, but with tests for Alpha CXML/DXML and IRIX SCSL and | |
| SGIMATH libraries commented out. | |
| Some macros do not conform to the Autoconf $PKG_$CATEGORY_$FOO | |
| naming scheme. These test for `features' such as GNOME, zlib, | |
| etc., are named R_$FEATURE, and typically define HAVE_$FEATURE. | |
| clibs.m4 | |
| versions of the autoconf macros to find the Fortran libraries | |
| amended to find the C libraries (for comparison with the Fortran | |
| ones). | |
| codeset.m4 | |
| is from GNU gettext and checks whether nl_langinfo(CODESET) | |
| is available in langinfo.h. | |
| gettext.m4 | |
| a concatenation of all the required files from gettext 0.14.5 | |
| except codeset.m4. | |
| gettext-lib.m4 | |
| a concatenation of the m4 files from gettext-0.14.5/autoconf-lib-link. | |
| libtool.m4 | |
| is from libtool 1.5.6. |
