AC_SEARCH_LIBS replaced AC_CHECK_LIBS. The latter had an action-if-found path that did not unilaterally set $LIBS if you provided a custom action. The former always changes $LIBS, even in the case of custom actions if found. This is an issue if you need to check for the existence of a library, but only use it in a subset of all of your things being compiled. Is this considered a bug in AC_SEARCH_LIBS, or is there a workaround I'm missing? _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx https://lists.gnu.org/mailman/listinfo/autoconf
