|
I'm installing gentoo on a brand-new laptop, and I've run into a problem.
I've compiled everything up from stage 1, and now I've switched from gcc 3.3.5 to 3.4.3.20050110-r1 I then changed the march cflag to read pentium-m. I recompiled gcc with no problems, and managed to compile linux26-headers and glibc just fine too.
Now I'm trying to emerge gnome, but I get an error on the very first package it tries to compile

I've got to admit that I'm stumped...any thoughts? |

Have you changed your compiler using gcc-config?
If you do, don't forget to do source /etc/profile afterwards |
