| 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. |
