Issue #1 is that you're reading the manual for 3.81 but using 3.80. The ability to use the "else if..." syntax was added in 3.81. The next issue is that your solution, even if you used the right version of make, isn't 100% correct. In particular, if you did "make clean IDL" you wouldn't want to include the dependency files, but the logic you gave would. I suggest the following solution, which as bonus works 3.80 too: ifneq (,$(if $(MAKECMDGOALS),$(filter-out clean IDL,$(MAKECMDGOALS)),X)) -include $(DEPFILES) endif I.e., if MAKECMDGOALS is non-empty and contains targets _other_ than 'clean' and 'IDL', then include the DEPFILES.
