This is because you're using a "match-anything" rule and GNU make has special operations for "match-anything" rules. See: http://www.gnu.org/software/make/manual/html_node/Match_002dAnything-Rules.html In particular the last 5 or so paragraphs. > Is there a way to make it succeed? Well, if you don't need to create the .m4 file from another file you can change your pattern rule to be terminal like this: %:: %.m4 m4 $^ > $@ Alternatively you can run make with the -r flag to get rid of all built -in rules, including the "special built-in dummy patterns". _______________________________________________ Help-make mailing list Help-make@gnu.org https://lists.gnu.org/mailman/listinfo/help-make
