Building LLVM

Windows:

• Install the following
  • CMake http://www.cmake.org/
  • MinGW http://www.mingw.org/
  • MSYS http://www.mingw.org/wiki/MSYS
  • MSYS DTK http://www.mingw.org/wiki/msys (Contains Perl)
• Add MinGW and MSYS bin directory to your PATH environment variable.
• Check out appropriate release from LLVM SVN repository http://llvm.org/svn/llvm-project/llvm
  • Releases are under /tags/RELEASE_* e.g. http://llvm.org/svn/llvm-project/llvm/tags/RELEASE_27
• Start CMake
• Within CMake change "Where is the source code" to your llvm source directory
• Within CMake change "Where to build the binaries" to a build directory
• Push "Configure", CMake will ask "Specify the generator for this project"
• Select "MSYS Makefiles" and choose "finish". CMake will work then present configuration options in red.
• Set configuration options, no changes are usually necessary
• Push "Configure" again and CMake will work again and the "Generate" button should become available
• Push "Generate" and CMake should put Makefiles in your build directory
• From the command line, navigate to your build directory and run "make"
