Development, Compiler


The LLVM Project is a collection of modular and reusable compiler and toolchain technologies. Despite its name, LLVM has little to do with traditional virtual machines, though it does provide helpful libraries that can be used to build them. The name "LLVM" itself is not an acronym; it is the full name of the project.

The llvm module sets several environment variables, which point to the different executables for the available compilers.
  • $CC → C compiler clang
  • $CXX → C++ compiler clang++
The path's to the executables will be set according to the LLVM version that is loaded.
