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

Answer 1

It sounds like you have Xcode 4.6 and the latest command line tools. This is from the release notes:

Important: The LLVM GCC compiler does not include the latest Objective-C and 
C++11 features. Xcode 4.6 is the last major Xcode release which includes the 
LLVM GCC compiler and the GDB debugger. Please migrate your projects to use the 
LLVM compiler and LLDB debugger…

I think you want to use c++ instead:

$ c++ -v
Apple LLVM version 4.2 (clang-425.0.24) (based on LLVM 3.2svn)
Target: x86_64-apple-darwin12.2.0
Thread model: posix
