Setup for LLVM

  • You have to have SVN and CMake available on your machine. So install these before your proceed, if your system does not have them already.

  • Create a folder named, say, llvm in a proper place (e.g. in ~).. Then, inside this folder, run this script. The script will fetch LLVM 4.0.0 files from its SVN repository, and then will build the files. Building will take a long time.

  • The script will create two folders: src_400 and build_400. Inside the build_400 there is a bin folder that includes clang and llvm tools. Put that bin folder into your PATH. E.g. Append the following file to your ~/.bashrc or ~/.bash_profile: export PATH=~/llvm/build_400/bin:$PATH

  • To check that your installation is OK, open up a new terminal window, and run the following command: llvm-config --version You should see 4.0.0 printed.
