I am considering the use of some C++11 features (like auto for instance) in some cross-platform projects (Windows+Mac). On Windows, Visual Studio supports parts of the upcoming C++11 standard that would allow me to simplify parts of the code base so naturally I would be interested in starting to use these features.

But as far as I am aware, the current XCode version (3.2.4 + GCC 4.2) does not support any C++11 features at all. Can I upgrade the GCC version or the CLang version somehow? Or should I just bite my tongue and wait for Apple to package a new version sometime in the future?

    Xcode 4.2 had finally added support for C++0X:

    1. In the project build settings screen, switch on “All” options.

    2. In the “Build Options” section, set compiler to “Apple LLVM compiler 3.0”.

    3. Scroll down to “Apple LLVM Compiler 3.0 – Language” section and set “C++ Language Dialect” to “C++0X” and “C++ Standard Library” to “libc++”.

    The std::move(), move constructor and R-Value reference are known to work as expected, and I’m testing on the std::thread and std::atomic.
