Hey
I am trying to build my front-end and its runtime library with libffi
support i am using:
AC_ARG_WITH(libffi,
AS_HELP_STRING([--without-libffi],
[don't use libffi]),
[:],
[with_libffi=${with_libffi_default-yes}])
LIBFFI=
LIBFFIINCS=
if test "$with_libffi" != no; then
AC_DEFINE(USE_LIBFFI, 1, [Define if we're to use libffi.])
LIBFFI=../libffi/libffi_convenience.la
LIBFFIINCS='-I$(top_srcdir)/../libffi/include -I../libffi/include'
fi
AC_SUBST(LIBFFI)
AC_SUBST(LIBFFIINCS)
in my configure.ac and its adding the flags necessary but it doesn't
seem to be building libffi before my runtime library i noticed in
Makefile.def in the toplevel i added:
target_modules = { module= libgpython; };
dependencies = { module=configure-target-libgpython;
on=configure-target-libffi; };
dependencies = { module=all-target-libgpython; on=all-target-libffi; };
languages = { language=python; gcc-check-target=check-python;
lib-check-target=check-target-libgpython; };
But it doesnt seem to have fixed the problem I am not quite sure how
this whole build system fits together plus i am not 100% comfortable
with autoconf in fear of messing things up.
