Enable static analyzer

  1. Install the latest version of clang-tidy

    For older versions of Ubuntu

    If you are using older version of Ubuntu (e.g. via Krita Docker build environment) make sure that you added the backports repository:

    sudo add-apt-repository ppa:savoury1/llvm-defaults-11
    sudo apt-get update
    sudo apt install clang-11 clang-format-11 clang-tidy-11 clang-tools-11
  2. Go to the Analyser settings in QtCreator (Options->Analyser)

  3. In the field for Clang-Tidy executable select the script from Krita source tree sdk/clang-tidy-arguments-wrapper.sh. This script removes GCC-specific compile options not supported by clang. Without the wrapper script the analyser tool will fail.

  4. Open "Diagnostic Configuration" dialog. Duplicate the default configuration, switch to "Clang-Tidy Checks" tab and choose "Use .clang-tidy config file"

  5. In the "Project Settings" pane make sure that your new Diagnostic Configuration is activated.

  6. Start analysing by clicking on Analyze->Clang Tidy and Clazy...
