qemu, gcc4, and 2006.1 profile

[tommoyer324]

I am trying to emerge qemu, but it won't build with gcc4, they recommend installing qemu with gcc3, so I thought I could just emerge -1 =gcc-3.4* to get the latest version, but I see that it is both keyworded ~ppc and masked by profile. I can get around the one by adding a line to package.keywords, but how would I unmask gcc-3.4 from the profile so that I can install qemu? Or this there a workaround to get it to install using gcc4? I looked but saw nothing conclusive, and most patches floating around the internet are x86 specific patches.

gcc-3.4* should not be masked I think (see http://packages.gentoo.org/search/?sstring=gcc).
On x86 i can compile qemu without errors with gcc-3.4*. With gcc-4.1* it fails.

Install a binary version of gcc3, use gcc-config to use that, then build qemu and uninstall gcc3.

If the binary version of gcc works, then the compiled version of qemu will work.

[timotheus25]

Uninstalling the gcc3 after compiling qemu could break qemu. It depends how one's system is setup for linking (AFAIK).

If you uninstalled every version of gcc on your system building new packages becomes difficult. Using existing packages only affects those that have gcc as a run-time dependency.

Looking at the qemu binaries on my system it seems that they do not link to gcc itself after all. I had assumed that they did.
