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?

Answer 1

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.

Answer 2

Each version of Xcode 4 adds new compiler support features. Please try Xcode 4.2 when it comes out.

Answer 3

Macports provides GCC 4.6, but any GCC version >= 4.2.1 (ie the latest official Apple GCC) cannot create universal binaries (32 and 64-bit code in one file) directly. There may be other drawbacks, but otherwise this should work for you.

Answer 4

Consider using Clang++ with libc++ http://libcxx.llvm.org/

It supports Mac OS X and has about 98% C++0x features finished except atomics.
