Clone llvm-project: https://github.com/sh-zam/llvm-project

Building clang-tidy

  • cd to llvm-project and then run cmake.
cmake -B build -G Ninja -DLLVM_ENABLE_PROJECTS="clang-tools-extra;clang" \
      -DLLVM_TARGET_ARCH="x86_64" -DCMAKE_EXPORT_COMPILE_COMMANDS=ON \
      -DLLVM_TARGETS_TO_BUILD="X86" -DCMAKE_BUILD_TYPE=Release ./llvm

Note: building in Debug mode causes SERIOUS paging issues.

Running checker on full source

  1. Set PATH or use the option in script for clang-tidy binary
  2. Get compilation database using cmake and link it to project root.
  3. Run clang-tidy on project using helper script in llvm-project

    Script is Located here: llvm-project/clang-tools-extra/clang-tidy/tool/run-clang-tidy.py

    ~/workspace/llvm-project/clang-tools-extra/clang-tidy/tool/run-clang-tidy.py \
    -checks='-*,misc-no-key-function' -header-filter='.*'

    I got lots of errors while it checked moc_*. I am not sure how to go about fixing them
