Why not just do: CPPFLAGS = -I/somewhere include foo/GNUmakefile CPPFLAGS = -I/elsewhere include bar/GNUmakefile Of course, if what you really meant was for all targets defined in the given makefiles to somehow magically have those values set, then of course the above won't do that. You'd have to do something like: include foo/GNUmakefile $(TARGETS) : CPPFLAGS = -I/somewhere include bar/GNUmakefile $(TARGETS) : CPPFLAGS = -I/somewhere Then in foo/GNUmakefile: TARGETS = foo foobiz foobaz and in bar/GNUmakefile: TARGETS = bar barbiz barbaz ps> I know I can specify per-target variables in newer makes, but can ps> I somehow specify an per-include variable as well? No, definitely not. ps> If not, would it be very difficult to add this feature? Yes. -- ------------------------------------------------------------------------------- Paul D.
