The test for pcrecpp has to be performed with a C++ compiler, otherwise the conditional will always be false. (You can enclose it in AC_LANG_PUSH/AC_LANG_POP, for example.) _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx http://lists.gnu.org/mailman/listinfo/autoconf
