Hi, I'm new to the autotools (and therefore also to this mailing list!) and I'm struggling to give the user some building options. I need to give the possibility to the user to specify custom directories for external libraries which must be linked to my program. So this would be an argument to the configure script like --<library name>-dir=<custom path>. I guess the given path must then be substituted in the makefiles with a "AC_SUBST(CUSTOM_DIR)" How to provide such an option (which macro in the configure.in file)? Thanks! _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx http://lists.gnu.org/mailman/listinfo/autoconf
