LLVM Clang 插件开发第一步

This article almost copy part of the official article, but fix many bugs that may impede newbees on the way to develop a clang plugin.

Environment : macOS

Step 0 : Obtain Clang

mkdir ~/clang-llvm && cd ~/clang-llvm
git clone <http://llvm.org/git/llvm.git>
cd llvm/tools
git clone <http://llvm.org/git/clang.git>
cd clang/tools
git clone <http://llvm.org/git/clang-tools-extra.git> extra

Step 1 : Obtain ninja and build

cd ~/clang-llvm
git clone <https://github.com/martine/ninja.git>
cd ninja
git checkout release
sudo cp ninja /usr/local/bin/

Step 2 : Obtain cmake and build

Your default cmake may not contain ninja support, so build cmake ourself.

cd ~/clang-llvm
git clone <https://gitlab.kitware.com/cmake/cmake.git>
cd cmake
sudo make install

Step 3 : Build clang

cd ~/clang-llvm
mkdir build && cd build
cmake -G Ninja ../llvm -DLLVM_BUILD_TESTS=ON  # Enable tests; default is off.
sudo ninja install

Of course , you should run the unittests before ninja install, but normally I run the unittest , always encounters some not pass. But just ignore these ‘errors’.

ninja check       # Test LLVM only.
ninja clang-test  # Test Clang only.

Step 4 : Clang tool

Just goto Create a ClangTool
