I’m a Mac OS X Lion user who uses Xcode for C++, and it appears that no updates are available for Xcode. I do not appear to be able to compile C++11-exclusive code, but for whatever reason, I thought Apple had gotten C++11 pretty much implemented. And yes, I do have support for Command Line Tools.
Then again, that might just be me. If so, is there any sort of IDE that supports C++11, or any way to upgrade?
I use Xcode and set the following settings:
C++ language dialect: C++11 or GNU++11
C++ Standart Library: libc++ (LLVM C++ standart library with C++11 support)
Xcode version: 4.3.2
