C3

Internal for the C3 project.

Building

• Build LLVM 4 and Clang from source (libclang.a is needed, and pre-built packages won't have it).
• Add directory containing llvm-config to your PATH, or set LLVM_CONFIG_PATH env variable poiting to the llvm-config executable file.
• Set LIBCLANG_INCLUDE_PATH pointing to Clang's include directory (<clang install dir>/clang/include/)

Building clang

• Install cmake, subversion, build-essential
• curl -LO http://releases.llvm.org/4.0.1/llvm-4.0.1.src.tar.xz
• tar xf llvm-4.0.1.src.tar.xz
• cd llvm-4.0.1.src/tools
• svn co http://llvm.org/svn/llvm-project/cfe/tags/RELEASE_401/final clang
• cd clang/tools
• svn co http://llvm.org/svn/llvm-project/clang-tools-extra/tags/RELEASE_401/final extra
• cd ../../..
• mkdir build; cd build
• Optionally
  • export LLVM_TARGETS_TO_BUILD=x86_64 (or your platform)
  • export LLVM_BUILD_TOOLS=OFF
  • export LLVM_INCLUDE_TESTS=OFF
  • export LLVM_BUILD_LLVM_DYLIB=OFF
• cmake -G "Unix Makefiles" ..
• make clang -j6
• Take a nap.
