The source file might be a built object and end up in the build directory. For a vendor make we know the two directories are the same, but we can't use $<. For GNU make the directories might be different, so we must search. Occasionally I've considered adopting a rule that if the source file doesn't have a target, then we know we can use $(srcdir). I'm a bit afraid to do this, though, since there might be weird cases I haven't thought of (but which some user has :-). Tom
