Utilize pre-installed MinGW in GitHub actions?

Currently I've been using egor-tensin/setup-mingw to setup MinGW for our CI and it's been working fine.

- name: Set up MinGW
  uses: egor-tensin/setup-mingw@v2
- name: Configure
  run: cmake -S. -B build ... -G "Ninja"

However, I noticed that the windows runner already has MinGW pre-installed:

# https://github.com/actions/runner-images/blob/main/images/win/Windows2022-Readme.md
Mingw-w64 11.2.0

Currently the aforementioned action takes about 5 minutes to setup MinGW. Ideally using the pre-installed MinGW would speed up this part of the CI process.

How can I use the pre-installed MinGW to speed up our GitHub workflow?

Solution

  • It's very simple, just use bash as the shell. This is how I do it:

      mingw64-gcc:
    name: MinGW GCC

    runs-on: windows-2019

    defaults:
      run:
        shell: bash

    steps:
      - name: "Setup"
        run: |
          gcc --version
