Actually... nothing is wasted. Actually, that's quite a BIT of waste. There's about 30(?), maybe more packages in system, depending on your use flags. About 4-5 are your toolchain. So, there's 25+ compiles wasted per system pass. You *might* need to compile your toolchain twice, but the critical package, gcc, already compiles itself twice. It compiles a minimal gcc (C-only, just enough to compile full gcc, and very portable across toolchains) using the current toochain then compiles full gcc (all your use flags settings, and requires gnuC extensions) using that minimal gcc. (That's the normal gcc build, not Gentoo specific.) After that, you normally only need to compile your applications ONCE. Cyclic dependencies could require more than one compile for full effect, but those are bad for other reasons, and could make it to where you have to recompile MORE than TWICE, depending on their complexity. In ANY case, you don't HAVE to rebuild you applications right away, and it would save you a few CPU cycles to just use the new compiler new time the package is updated. If you are running ~ARCH that generally pretty often. :) -- If there's one thing we've established over the years, it's that the vast majority of our users don't have the slightest clue what's best for them in terms of package stability. -- Gentoo Developer Ciaran McCreesh pgpO8boYriykX.pgp Description: PGP signature

Re: [gentoo-user] After gcc-3.4.6-r1 glibc-2.4-r2 emerge!
Hello all, I thank you all fo responses to this posting of mine. Now that I was following this thread I just read the one that states that the emerge -e world does also emerge -e system stuff, so now that I am in the mid of doing emerge -e system how can I run emerge -e world with out doing all of them again and only doing the ones that did not get done doing a emerge -e system?

Re: [gentoo-user] After gcc-3.4.6-r1 glibc-2.4-r2 emerge!
I can't find the exact discussion on the subject of running two emerges for both system and world, but this link gives the kernel of the idea. The original doc went into some details that's missing here and as mentioned, following the suggestions helped clear up some goofy mplayer problems I was having. http://lcni.uoregon.edu/mediawiki/index.php/SOFT:Gentoo_AMD64_1 Emerging world twice may be a bit overkill, but then it's never something I sit and watch... It's amazing what you can do with a bit of bash and cron when you are happily sleeping. Cheers...

[gentoo-user] After gcc-3.4.6-r1 glibc-2.4-r2 emerge!
Hello All, What should I do after I do a emerge of gcc and glibc vers in subject line? I have also when doing that emerged told it to do kde and gnome so both of them will be at the latest versions in the tree that are ~amd64. X 7 modular is already on the system and appears to be working great. Sincerely, Christopher -- gentoo-user@gentoo.org mailing list
