title: How can I run software that compiled with new C++ standard library on old os x
body: <p>I have a software that compiled with libc++ (LLVM C++ standard library with C++11 support). My software works good on new operation systems (os x 10.9 and above). The problem is that my software crashes on old operation systems (os x 10.8 and below). I think it because the default C++ runtime on OS X 10.8 and earlier is a version of libstdc++ based on GCC 4.2.1 which does not support C++11. 
  What can I do?</p>
