A shell variable doesn't fit the bill. Likewise for AC_DEFINE. This is because other tools like autoheader and automake need to know the variable/define names. So, you can either move the AC_SUBST out of the loop and do them in the callers of the macro, where you know the literal name of the variable, or replace the 'for lxlib' shell loop with an m4 AC_FOREACH loop and adjust loop contents. Hope that helps. Cheers, Ralf _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx http://lists.gnu.org/mailman/listinfo/autoconf
