編譯帶有除錯資訊的 LLVM/Clang
1 2 3 4 5 6 | $ git clone https://github.com/llvm/llvm-project.git $ cd llvm-project $ mkdir build $ cd build $ cmake -G Ninja -DCMAKE_BUILD_TYPE=Debug -DLLVM_ENABLE_PROJECTS='clang' -DLLVM_ENABLE_RTTI=ON -DLLVM_CCACHE_BUILD=ON -DLLVM_BUILD_LLVM_DYLIB=ON -DLLVM_LINK_LLVM_DYLIB=ON -DLLVM_ENABLE_ABI_BREAKING_CHECKS=OFF -DLLVM_USE_LINKER=lld -DLLVM_USE_SPLIT_DWARF=ON -DLLVM_TARGETS_TO_BUILD='X86' -DLLVM_INCLUDE_EXAMPLES=OFF -DLLVM_INCLUDE_BENCHMARKS=OFF -DLLVM_INCLUDE_TESTS=OFF -DLLVM_ENABLE_LTO=OFF -DLLVM_OPTIMIZED_TABLEGEN=ON -DCLANG_ENABLE_STATIC_ANALYZER=OFF -DCLANG_ENABLE_ARCMT=OFF ../llvm $ ninja -j |
- LLVM CMake Build Reference: https://llvm.org/docs/CMake.html
- LLVM Getting Started: https://llvm.org/docs/GettingStarted.html
快速編譯以及快速連結請參考 LLVM Getting Started 的 Common Problem 的 CMake 選項，上面的範例 CMake 選項已經將 Common Problem 的選項開啟 (或關閉)。
替換編譯時使用的 dynamic library
CMake – CMakeLists.txt

編譯連結時出現 undefined reference to `llvm::DisableABIBreakingChecks’
- 確認 include directories 是不是正確的:
target_include_directories( foobar PUBLIC /home/llvm-project/build/include)
- 確認編譯 LLVM/Clang 時是否有加上
LLVM_ENABLE_ABI_BREAKING_CHECKS=OFF- 可以透過
cmake .來更新 build options
- 可以透過
- make clean 後重新編譯
