Build LLVM/Clang (3.3) on Windows x64

In order to get clang_complete to work on Windows x64 with Vim x64 and Python x64, libclang.dll must first be compiled from source.

Prerequisites

• Visual Studio 2010 or 2012
• Recent Vim x64 with Python27 support
• Python 2.7 x64
• CMake for Windows

Build

1. Checkout llvm and clang using subversion. Trunk is version 3.3 at the time of this writing.
   

   svn co http://llvm.org/svn/llvm-project/llvm/trunk llvm
   cd llvm\tools
   svn co http://llvm.org/svn/llvm-project/cfe/trunk clang
   

2. Configure using cmake. Tweak the build command below to suit your system.
   

   cmake C:\absolute\path\to\llvm -DPYTHON_EXECUTABLE="C:\Python27\python.exe" -DSubversion_SVN_EXECUTABLE="C:\Program Files\SlikSvn\bin\svn.exe" -DCMAKE_INSTALL_PREFIX="C:\clang" -DCMAKE_BUILD_TYPE=Release -DLLVM_TARGETS_TO_BUILD=X86;CppBackend -G "Visual Studio 11 Win64"
   

3. Build using cmake.
   

   cmake --build . --config Release

4. Install using cmake.
   

   cmake --build . --config Release --target install

Install clang_complete

1. Use Vundle or Pathogen to install clang_complete.
2. In your vimrc, point clang_complete to your newly-compiled libclang.dll.
   

   if has('win64')
       let g:clang_library_path='C:/clang/bin'
   endif
