That's hardly enough. :-) I see :-) Suppose you have a file x.c, and you invoke env SUNPRO_DEPENDENCIES="x.deps build/x.o" gcc -c -o x.o x.c then a file x.deps is generated, and has, on the left-hand side of the dependency rule, build/x.o. It works the same way for compilers identifying themselves as cc: Sun WorkShop 6 update 1 C 5.2 2000/09/11 when invoked with -V. I can't give a complete list of compilers that support that feature, but setting the variable can't hurt - the worst case is that it is ignored. Regards, Martin
