In this case, the problem is that the user will have to be informed of that _before_ doing the gobo compilation. As per ebuild rules, we are not allowed to stop the build process and ask the user for input, so at best, he'd see a notice scrolling by at high speed saying "this package would take 2mins to compile if you have chosen tcc, but you haven't, too bad for you". I certainly agree with you that the CC=tcc is a nicer approach (perhaps even the nicest approach of them all), but it requires the user to actually _know_ he can benefit from using tcc on gobo beforehand. That's a very steep requirement imho, given the fact that very few people have heard of tcc, nobody's heard of gobo, and it's hardly commonplace to think you can get a 30x improvement in compilation time just by switching compilers :) Kind regards, Karl T -- gentoo-dev@g.o mailing list
