If you are using Automake, then _not_ using the option 'nostdinc' will cause the right include paths to be added to preprocessor invocations, so that #include <config.h> should work for both in-tree and VPATH builds. No need to add any other include flags manually: <http://www.gnu.org/software/automake/manual/html_node/Program-Variables.html> (This is implemented internally with the DEFAULT_INCLUDES variable, as John already explained.) And BTW, if you are ever including paths to build and source tree locations manually, that coincide when building in-tree, then you should list the build tree path first, for consistent semantics, e.g.: -I. -I$(srcdir) Cheers, Ralf _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx http://lists.gnu.org/mailman/listinfo/autoconf
