This page lists the requirements for running
bindgen and how to get them.
libclang to preprocess, parse, and type check C and C++
It is recommended to use Clang 3.9 or greater, however
bindgen can run with
older Clangs with some features disabled.
If you are generating bindings to C, 3.7 and 3.8 will probably work OK for you.
If you are generating bindings to C++, you almost definitely want 3.9 or greater.
Installing Clang 3.9
Download and install the official pre-built binary from LLVM download page.
You will also need to set
LIBCLANG_PATH as an environment
bin directory of your LLVM install. For example, if you installed LLVM
D:\programs\LLVM, then you'd set the value to be
If you use Homebrew:
$ brew install llvm
If you use MacPorts:
$ port install clang-3.9
# apt-get install llvm-3.9-dev libclang-3.9-dev clang-3.9
Ubuntu 16.10 provides the necessary packages directly. If you are using older version of Ubuntu or other Debian-based distros, you may need to add the LLVM repos to get version 3.9. See http://apt.llvm.org/.
# pacman -S clang
If your package manager doesn't yet offer Clang 3.9, you'll need to build from source. For that, follow the instructions here.
Those instructions list optional steps. For
- Checkout and build clang
- Checkout and build the extra-clang-tools
- You do not need to checkout or build compiler-rt
- You do not need to checkout or build libcxx
