The sccache action can be used in GitHub Actions workflows to integrate sccache into the build process. The sccache action is a step in a workflow that can be used to cache compilation results for subsequent builds, reducing the build time and speeding up the overall development process.

sccache can easily use GitHub actions cache with almost no configuration.

This action is available on: https://github.com/marketplace/actions/sccache-action

Just copy and paste the following in your GitHub action:

- name: Run sccache-cache
  uses: mozilla-actions/[email protected]

- name: Run sccache-cache only on non-release runs
  if: github.event_name != 'release' && github.event_name != 'workflow_dispatch'
  uses: mozilla-actions/[email protected]
- name: Set Rust caching env vars only on non-release runs
  if: github.event_name != 'release' && github.event_name != 'workflow_dispatch'
  run: |
    echo "SCCACHE_GHA_ENABLED=true" >> $GITHUB_ENV
    echo "RUSTC_WRAPPER=sccache" >> $GITHUB_ENV

- name: Run sccache-cache
  uses: mozilla-actions/[email protected]
  with:
    version: "v0.7.4"

Note that using the previous declaration will automatically create a Post Run sccache-cache task.

- name: Run sccache stat for check
  shell: bash
  run: ${SCCACHE_PATH} --show-stats

- name: Run sccache-cache
  uses: mozilla-actions/sccache-action
  with:
    disable_annotations: true

For Rust code, the following environment variables should be set:

    env:
      SCCACHE_GHA_ENABLED: "true"
      RUSTC_WRAPPER: "sccache"

For C/C++ code, the following environment variables should be set:

    env:
      SCCACHE_GHA_ENABLED: "true"

With cmake, add the following argument:

-DCMAKE_C_COMPILER_LAUNCHER=sccache
-DCMAKE_CXX_COMPILER_LAUNCHER=sccache

With configure, call it with:

# With gcc
./configure CC="sccache gcc" CXX="sccache gcc"
# With clang
./configure CC="sccache clang" CXX="sccache clang"

When using the action on GitHub Enterprise Server installations a valid GitHub.com token must be provided.

- name: Run sccache-cache
  uses: mozilla-actions/[email protected]
  with:
    token: ${{ secrets.MY_GITHUB_TOKEN }}

Note that using https://github.com/actions/create-github-app-token is a better option than storing a fixed token in the repo secrets.

1. Update the example in README.md
2. Update version in package.json
3. Run npm i --package-lock-only
4. Commit and push the local changes
5. Tag a new release (vX.X.X)
6. Create a new release in github
