Hi Matthew, Thanks for the help. I would have liked to use the second substitution mechanism (foo=$@) because it is part of the POSIX specification of `make' (http://www.opengroup.org/onlinepubs/009695399/utilities/make.html), whereas the first form (S/foo/$@/g) doesn't seem to be so. > You have got a line: > > .PHONY: dir1 dir2 > > to force those rules to be applied even if dir1 or dir2 are newer than > their sources? Yes, I had tried that too, but it doesn't make the second rule work. The second rule does work with `gmake'. Cheers, Raghavendra. -- N.
