Answer 1

I installed gcc-4.7 on my Mac to make C++11 work. GCC in its current version is fairly good at supporting C++11, so this should be a fair choice.

The installation can be done by Homebrew and is not that complicated (at least I was able to do it...)

To install Homebrew if you do not already have it:

ruby -e "$(curl -fsSkL raw.github.com/mxcl/homebrew/go)"

Now run

brew doctor

and fix whatever problems come up (there is something written in the hombrew documentation for that). Finally, install current gcc:

brew install gcc

If everything goes well you should be able to access g++-4.7, which allows -std=c++0x.
