I installed the llvm and clang according to the official documentation.
Then I add the build/bin path to the environment and source the bashrc.
My OS is ubuntu 14.04. However, when I typed clang --version. I have the following exception
The program ‘clang’ can be found in the following packages:
Try: sudo apt-get install
The other binaries like llvm-ar works well. Do anyone know the reason? Many thanks
