About the {% data variables.product.prodname_codeql_workflow %} and compiled languages

You enable {% data variables.product.prodname_dotcom %} to run {% data variables.product.prodname_code_scanning %} for your repository by adding a {% data variables.product.prodname_actions %} workflow to the repository. For {% data variables.product.prodname_codeql %} {% data variables.product.prodname_code_scanning %}, you add the {% data variables.product.prodname_codeql_workflow %}. For more information, see "Enabling {% data variables.product.prodname_code_scanning %} for a repository."

{% data reusables.code-scanning.edit-workflow %} For general information about configuring {% data variables.product.prodname_code_scanning %} and editing workflow files, see "Configuring {% data variables.product.prodname_code_scanning %}" and "Configuring a workflow."

{% note %}

Note: If you use self-hosted runners for {% data variables.product.prodname_actions %}, you may need to install additional software to use the autobuild process. Additionally, if your repository requires a specific version of a build tool, you may need to install it manually. For more information, see "Software installed on GitHub-hosted runners."

C/C++

Supported system type	System name
Operating system	Windows and Linux
Build system	Autoconf, CMake, qmake, Meson, Waf, SCons, and Linux Kbuild

The behavior of the autobuild step varies according to the operating system that the extraction runs on. On Windows, the step has no default actions. On Linux, this step reviews the files present in the repository to determine the build system used:

1. Look for a build system in the root directory.
2. If none are found, search subdirectories for a unique directory with a build system for C/C++.
3. Run an appropriate command to configure the system.

C

Supported system type	System name
Operating system	Windows and Linux
Build system	.NET and MSbuild, as well as build scripts

The autobuild process attempts to autodetect a suitable build method for C# using the following approach:

1. Invoke dotnet build on the solution (.sln) or project (.csproj) file closest to the root.
2. Invoke MSbuild (Linux) or MSBuild.exe (Windows) on the solution or project file closest to the root. If autobuild detects multiple solution or project files at the same (shortest) depth from the top level directory, it will attempt to build all of them.
3. Invoke a script that looks like a build script—build and build.sh (in that order, for Linux) or build.bat, build.cmd, and build.exe (in that order, for Windows).

Java

Supported system type	System name
Operating system	Windows, macOS and Linux (no restriction)
Build system	Gradle, Maven and Ant

The autobuild process tries to determine the build system for Java codebases by applying this strategy:

1. Search for a build file in the root directory. Check for Gradle then Maven then Ant build files.
2. Run the first build file found. If both Gradle and Maven files are present, the Gradle file is used.
3. Otherwise, search for build files in direct subdirectories of the root directory. If only one subdirectory contains build files, run the first file identified in that subdirectory (using the same preference as for 1). If more than one subdirectory contains build files, report an error.

Adding build steps for a compiled language

{% data reusables.code-scanning.autobuild-add-build-steps %} For information about editing the workflow, see "Configuring {% data variables.product.prodname_code_scanning %}."

After removing the autobuild step, uncomment the run step and add build commands that are suitable for your repository. The workflow run step runs command-line programs using the operating system's shell. You can modify these commands and add more commands to customize the build process.

- run: |
  make bootstrap
  make release

For more information about the run keyword, see "Workflow syntax for {% data variables.product.prodname_actions %}."

You can also use a build matrix to update the workflow to build more than one compiled language, if this is the appropriate approach for your system and doesn't cause conflicts. For more information, see "Configuring a build matrix."

For example, the workflow below runs one job for C/C++ analysis, and another job for Java analysis.

name: "CodeQL"

on:
  push:
    branches: [main, ]
  pull_request:
    branches: [main]

jobs:
  CodeQL-Build:

    strategy:
      fail-fast: false
      matrix:
        language: ['cpp', 'java']

{% if currentVersion ver_gt "enterprise-server@2.21" %}    runs-on: self-hosted
{% else %}    # CodeQL runs on ubuntu-latest, windows-latest, and macos-latest
    runs-on: ubuntu-latest{% endif %}

    steps:
    - name: Checkout repository
      uses: actions/checkout@v2

    # Initializes the CodeQL tools for scanning.
    - name: Initialize CodeQL
      uses: github/codeql-action/init@v1
      with:
        languages: ${% raw %}{{ matrix.language }}{% endraw %}

    # Autobuild attempts to build any compiled languages  (C/C++, C#, or Java).
    # If this step fails, then you should remove it and run the build manually.
    - name: Autobuild
      uses: github/codeql-action/autobuild@v1

    - name: Perform CodeQL Analysis
      uses: github/codeql-action/analyze@v1

If you added manual build steps for compiled languages or used a build matrix and {% data variables.product.prodname_code_scanning %} is still not working on your repository, contact {% data variables.contact.contact_support %}.
