how do i build gcc on a mac?

Question

I'd like to build the latest version of gcc on a mac. I have the latest xcode but I'm looking for some of the c++0x features that are in more recent versions (the lambda functions, etc).

Are there any good step-by-step tutorials on doing this?

Answer 1

You should look at the Homebrew project.

Homebrew allows you to do things like this:

brew install gcc

Mac homebrew installation instructions are available here.
