The R Project SVN R

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.

  am-fixes.m4
    contains R specific versions of
        AM_INIT_AUTOMAKE
        AM_MISSING_PROG
    These are necessary to work around a problem in the current
    release version of automake/aclocal in determining missing_dir
    with zsh (problem with CDPATH and pwd; see the docs in the
    autoconf CVS for more info).  Note that the current (2001-04-27)
    automake CVS has a 2-arg only version of AM_MISSING_PROG.

  gnome-gnorba-check.m4
  gnome-orbit-check.m4
  gnome.m4
  libglade.m4
    are from the GNOME project and used for the GNOME configuration.
    Changes made in gnome.m4:
    * Replace AC_ARG_WITH(gnome) by our version in configure.in
      because we need want_gnome=no by default and use LIBS and
      CPPFLAGS rather than LDFLAGS and CFLAGS.
    * In AC_ARG_WITH(gnome-includes), standardize doc strings and
      use CPPFLAGS rather than CFLAGS.
    * In AC_ARG_WITH(gnome-libs), standardize doc strings and use
      LIBS rather than LDFLAGS.
    Changes made in libglade.m4:
    * In AC_ARG_WITH(libglade-config), standardize doc strings.

  libtool.m4
    is from libtool 1.4.
    Changes made: one typo fixed (fixed in 1.4a or better).
