If you would like some help please post a minimal, complete example (and create a new mailing list thread for it).

Variables are expanded before the pattern is substituted, so $(%_OBJ) tries to expand the variable %_OBJ which is empty. ___ Bug-make mailing list Bug-make@gnu.org https://lists.gnu.org/mailman/listinfo/bug-make

For completeness's sake, note another approach that might work: TARGETS = bin/animation.exe bin/barchart.exe ... $(TARGETS): bin/%.exe: $(%_OBJ) $(LIBS) $(call link_EXE, $@, $^) using the other kind of pattern rule, Eddy. ___ Bug-make mailing list Bug-make@gnu.org https://lists.gnu.org/mailman/listinfo/bug-make
