Are there any good ppa's for gcc4.7 and the required libstdc++? Perferably for ubuntu 11.10, Any links are appreciated!
No PPA needed. There's gcc-snapshot package in
Of course, it's only 4.7 until 4.8 development starts in a few months time, at which point I'd expect there to be a gcc-4.7 package, although I don't know for sure.
