Can I use C++11 with Xcode?
It seems like xcode 4 contains older versions of clang and gcc. Can i uppgrade gcc or clang and use them with xcode 4? I would like to use gcc >= 4.6 or the latest clang.
My main goal is to be able to have as much of the new features from C++11 available when programming C++ on mac osx lion so ditching xcode is also an option if that is needed.
What are my options to achieve this?
The version of clang in Xcode 4.1 does support some C++11 features, including variadic templates and rvalue references. Also libc++, an implementation of the C++11 standard library is included in Lion.
See my answer to Osx Lion: Xcode 4.1 how do I setup a c++0x project for details on setting this up.
