The configure script can't find grep on Windows on GitHub Actions-CodePudding

I'm trying to make a PR to build my Haskell project on Windows on Github Actions, but the configuration script of the process-1.6.14.0 can't find grep. The complete GA log is here and here (the same log but I've uploaded it as a Gists in case the log retention time is expired).

grep is installed on /usr/bin/grep.

  which grep
  grep --version
  /usr/bin/grep --version
  shell: D:\a\_temp\setup-msys2\msys2.CMD {0}
  env:
    MSYSTEM: MINGW64
/usr/bin/grep

However, the configuration script can't find it.

checking for grep that handles long lines and -e... configure: error: no acceptable grep could be found in /mingw64/bin:/c/Users/runneradmin/AppData/Roaming/cabal/bin:/usr/bin:/d/a/_temp/msys64/mingw64/bin:/d/a/_temp/msys64/usr/local/bin:/d/a/_temp/msys64/usr/bin:/d/a/_temp/msys64/usr/bin:/c/Windows/System32:/c/Windows:/c/Windows/System32/Wbem:/c/Windows/System32/WindowsPowerShell/v1.0:/d/a/_temp/msys64/usr/bin/site_perl:/d/a/_temp/msys64/usr/bin/vendor_perl:/d/a/_temp/msys64/usr/bin/core_perl;/usr/xpg4/bin

I think that grep satisfies all the requirements because I could build process-1.6.14.0 on my local Windows with the same version of grep.

Here is the GA script.

Why is the build failed on GA?

CodePudding user response：

The configuration script accepts the GREP variable to specify where grep is. So, I updated the GA script.

    - name: Store the path to Cabal (Windows)
      run: |
        echo "GREP=$(which grep) $(cygpath --unix '${{ steps.haskell_setup.outputs.cabal-exe }}') "'$@ '"-w $(cygpath --unix '${{ steps.haskell_setup.outputs.ghc-exe }}')" > cabal.sh
        chmod  x cabal.sh
      if: runner.os == 'Windows'
