Now it works with AC_CHECK_LIB but not with AC_SEARCH_LIBS because the exit function doesn't need any library. Since I know this library is mandatory for the read_graphviz function, it's OK. But I would know how to check the presence of a function defined in a namespace, or with template parameters ? -- Johan _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx http://lists.gnu.org/mailman/listinfo/autoconf
