getting c++11 - compliant compiler

Question

This all seems like a colossal mess.
All I want is a compiler that implements C++11, so I can use . But I\'m so confused from the very beginni

@sharth: The situation changed on the Mac quite significantly since the release of XCode 5.0. clang/clang++ are the default C/C++ compilers. They correspond to the LLVM version 3.3 I believe, and this version of clang++ is fully C++11-compliant. Note that clang++ --version will return a version number like "5.0.x" on the Mac but that refers to the XCode version.

I have been using the Apple clang++ in a C++11 project for months now and so far I have not seen any problems. There is absolutely no reason to use any other C++ compiler on the Mac just now :-)

The situation with GCC/G++ is not so rosy. The latest version of G++ (4.8.2) does implement most of the C++11 standard, however the standard library is not compliant! For instance, std::regex is not implemented in libstdc++, but you find this out only when you run your code and the regex constructors throw std::regex_error -s. (I found this out the hard way when trying to port the aforementioned little project to Linux.) The community believes full compliance will be achieved with the 4.9 release of G++. Until then you should use the Clang compilers on Linux as well.

I have no access to the latest Intel C++ compiler suite so have no idea how compliant icpc is.
