This approach uses update-alternatives to manage GCC and LLVM/CLANG C/C++ compiler toolchains. Although tested on Linux Mint 18.3, this approach should work on any Debian based distro or for that matter any Linux distro with update-alternatives support, provided the packages are installed correctly.

There are 3 files

• gcc-alternatives.sh installs GCC versions 5/6/7 and sets up alternatives for gcc/g++/cpp/gfortran.
• llvm-clang-alternatives.sh installs LLVM and CLANG versions 4/5 and sets up alternatives for various LLVM and CLANG programs including clang and clang++.
• cc-alternatives.sh sets up alternatives for the cc, cxx, and the ld commands. This script can be used to change systemwide default compiler/linker combination to either GCC or CLANG.

Once these scripts are run you can change the system GCC/CLANG versions by running sudo update-alternatives --config gcc|clang. To change the default compiler/linker combo used by t
