Hi all, In my configure.ac I simply invoke: AC_PROG_UPC … $ aclocal … aclocal:configure.ac:12: warning: macro `AM_PROG_UPC' not found in library … $ autoconf Configure.ac:12: error: possibly undefined macro: AM_PROG_UPC If this token and others are legitimate, please use m4patternallow. See the Autoconf documentation. Is this a non-standard macro? Then, how can I add UPC support to my Autotools project? Thanks, Justin _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx https://lists.gnu.org/mailman/listinfo/autoconf
