GCC \nis always installed with multilib support, i.e. `-m32`, `-mx32`, and `-m64` are \nsupported.\n\n## Clang images\n\n- `ghcr.io/mattkretz/cplusplus-ci/clang14`\n- `ghcr.io/mattkretz/cplusplus-ci/clang15`\n- `ghcr.io/mattkretz/cplusplus-ci/clang16`\n- `ghcr.io/mattkretz/cplusplus-ci/clang17`\n- `ghcr.io/mattkretz/cplusplus-ci/clang18`\n- `ghcr.io/mattkretz/cplusplus-ci/clang19`\n- `ghcr.io/mattkretz/cplusplus-ci/clang20`\n- `ghcr.io/mattkretz/cplusplus-ci/clang21`\n- `ghcr.io/mattkretz/cplusplus-ci/clang22`\n- `ghcr.io/mattkretz/cplusplus-ci/clang23`\n\nThe Clang images provide `clang`, `clang++`, `clang-tidy`, and `clang-format` \naliases to the respective version.\n\n## Deprecated images\n\nThe\n`ghcr.io/mattkretz/cplusplus-ci/base` and \n`ghcr.io/mattkretz/cplusplus-ci/latest` images are deprecated and will not be \nupdated anymore.\n\n---\n\n## Example GitHub CI Workflow\n\n```yaml\nname: Clang\n\non:\n  push:\n    branches: [ main ]\n  pull_request:\n\njobs:\n  clang:\n    strategy:\n      fail-fast: false\n      matrix:\n        version: [21, 22]\n\n    runs-on: ubuntu-latest\n\n    container:\n      image: ghcr.io/mattkretz/cplusplus-ci/clang${{ matrix.version }}\n\n    steps:\n      - uses: actions/checkout@v4\n\n      - name: Run test suite\n        env:\n          CXX: clang++\n        run: make check\n```\n\n## Latest CMake\n\nIf you want to use latest CMake add the following step to your workflow before \na step that needs `cmake`:\n\n```yaml\n      - name: Set PATH for cmake-latest\n        run: echo /opt/cmake-latest/bin \u003e\u003e $GITHUB_PATH\n```\n\n\n## Updates\n\nThe `gcc15`, `gcc16`, and `gcc17` images are updated once per week. All other images are \nupdated once per month. There may also be manual updates whenever the feature \nset needs to change.\n","funding_links":[],"categories":[],"sub_categories":[],"project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmattkretz%2Fcplusplus-ci","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fmattkretz%2Fcplusplus-ci","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmattkretz%2Fcplusplus-ci/lists"}
