Clang C/C++ Download and Installation

Download/Install the Clang Compilers

Clang is the C/C++ complier that we will use in ICS-46. The version I installed (on 9/16/2016) is Apple version LLVM 6.0 (clang-600.0.57) (based on LLVM 3.5svn).

After following the instruction here, you will download a version of CLion, an Integrated Development Environment (IDE) for using these compilers (or you can choose to use these compilers via a command-line). In the process, you will also install Xcode's command line developer tools.

You may want to print these instructions before proceeding, so that you can refer to them while downloading and installing the Clang compilers. Or, just keep this document in your browser. You should read each step completely, before performing the action that it describes.
