I'm looking for a PPA with the latest and greatest version of GCC. I'm too scared to switch to something totally unstable and knock my production system out of wack, but want the newest version of GCC. Additionally I don't want to waste tons of time building my own version of GCC.

Contradiction much? you want the latest and greatest, yet you don't want it to be unstable?... bleeding edge is not for you then, stick to what you have if instability is not what you want. –  Uri Herrera Dec 11 '11 at 0:52
    
Ubuntu has 6.4.1 GNU has 4.6.2 as stable. GCC 4.7.0 is unstable. The cool distros have 4.6.2 in their stable repos. –  Mikhail Dec 11 '11 at 1:05
    
So..?, if you're about to use GCC you should know how to compile software anyways. Ubuntu is not a rolling release distro you know that.. the repositories are frozen before Ubuntu is released and whatever the version of the software is at that point (should the developers send their packages to Canonical) that's the version that you'll get. –  Uri Herrera Dec 11 '11 at 1:15
    
Your only option is to wait for someone to create a PPA and upload THAT specific version of GCC, PPAs are not maintained by Canonical, and neither is this site is affiliated to them so you can't just come here and REQUEST a PPA. –  Uri Herrera Dec 11 '11 at 1:17
    
@if you're about to use GCC you should know how to compile software anyways... I know how to do it and I know it will take me a few hours. –  Mikhail Dec 11 '11 at 1:25

This is documented here: https://wiki.ubuntu.com/ToolChain

The toolchains that are currently being used to build 12.04 should be there, I think, although that page is slightly out of date.

This, and similar problems were solved by switching to Gentoo for our development rig. Unless you want to dedicate a lot of time to setting up your own build system, Ubuntu is not the way to go. In Gentoo you type in emerge -a gcc and all your problems are solved. We always have the latest and greatest software.
