title: How to update the clang version to compile a C++11 project? (on Mac)
body: <p>I'm trying to build a project which is originally written for archlinux. The building process works fine on that archlinux but has a huge amount of errors when I tried to build it on my mac. The project is basically written in C++11 so it's very unstable. I think there has something to do with the compiler because the clang version in mac is 4.2(It actually shows <strong>'Apple LLVM version 4.2 (clang-425.0.28) (based on LLVM 3.2svn)'</strong> when I type <strong>clang --version</strong>) and 3.3 for linux. So I want a different version of clang, perhaps 3.3. How Can I specify the version of my compiler when trying to build the project?</p>
