I have a configure.ac here which uses AC_PROG_LD, but I don't know about the purpose of this macro. Unfortunately I do not find and any doc about it. AC_PROG_LD is a old macro from libtool (though more aptly named), you should use LT_PATH_LD instead. (libtool) Autoconf macros: -- Macro: LT_PATH_LD Add a `--with-gnu-ld' option to `configure'. Try to find the path to the linker used by `$CC', and whether it is the GNU linker. The result is stored in the shell variable `$LD', which is `AC_SUBST'ed. _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx http://lists.gnu.org/mailman/listinfo/autoconf
