Otherwise, you'd have to have many separate dependency lines, I agree that allowing $@ in prerequisites would allow easy to read and easy to write Makefiles, but the lack of that functionality does not mean that the same build method for multiple targets needs to get split up to different dependency lines. With a static pattern rule you can do the same on with a single line: cat date echo ls pwd rm sleep sync test : % : %.o regards Henrik
