GCC takes a long time to compile and re-compile itself with itself, but since you experience it to be longer than usual, you probably have a different settings, like -jX in MAKEOPTS or trying to compile it in framebuffer, which takes longer, in my experience, I assume it might be related to very slow echo operations, or might be just a glitch of my perception ;) -- Mike Kazantsev // fraggod.net signature.asc Description: PGP signature

That loop is the multilib profile you're probably using, which will compile you both 64-bit and 32-bit version of gcc? You also stated in an earlier email that your system has an Athlon 3000+ processor. As a comparison, here with an Athlon 3500+ and 3GB of RAM the gcc:4.3 compilation takes around two hours if the ccache is empty and an hour and 20 minutes if it hits mostly the cache, so the duration doesn't appear surprising for a first compilation (varying by the USE flags, naturally). -- Arttu V.

I'm still fighting with my two machines, recompiling system, and world with new GCC even though, it was not necessary; I wish developers mentioned it after emerging new gcc no need to recompile the system I just read few posts on the forum and did what others suggested: recompiled the world but is is not going smooth; maybe it is time for me to try something easier ubuntu etc as I'm not very happy with Gentoo, the upgrade and installation are harder to manage. -- Joseph

Please tell... -- ~adj~ Yes, I did it at the beginning of the year, it was more or less painfree. There were a couple of compile failures with stable packages when rebuilding the world, but typically these are already fixed and in bugzilla, so you can go ahead by installing the ~x86 package. (See http://bugs.gentoo.org/show_bug.cgi?id=245160 for a tracker of the packages) I did not notice any difference in using the system everyday, I did it only because I can use -march=core2 now and I wanted to work with the newer gcc when programming other things.
