Windows build environment fails to propagate to CMake external project

Description

https://github.com/ament/uncrustify_vendor uses a CMake external project (uncrustify).

Expected Behavior

Builds fine on Windows.

Actual Behavior

Fails to build on Windows. It fails when CMake checks for C and CXX compilers. The vendor CMake project can find the compiler just fine, but the external project cannot.

To Reproduce

Build uncrustify_vendor on Windows, e.g.

    - uses: ros-tooling/setup-ros@master
    - uses: ros-tooling/action-ros-ci@master
      with:
        package-name: uncrustify_vendor
        vcs-repo-file-url: https://raw.githubusercontent.com/ros2/ros2/master/ros2.repos

For a full example, see rmw_cyclonedds's CI config: https://github.com/ros2/rmw_cyclonedds/blob/2bbc260b987523b131fd8f5bbc002d5fc9801e0b/.github/workflows/CI.yml

System

  • OS: Windows
  • ROS 2 Distro: Rolling (possibly any other recent distro)

Additional context

I think that action-ros-ci's Windows build environment might not be correctly set up. We're running some scripts along with each command on Windows (to setup the build environment?), but maybe it doesn't properly propagate:

action-ros-ci/src/action-ros-ci.ts

Lines 114 to 133 in 16b8198

if (isWindows) {
toolRunnerCommandLine = "C:\\Windows\\system32\\cmd.exe";
// This passes the same flags to cmd.exe that "run:" in a workflow.
// https://help.github.com/en/actions/automating-your-workflow-with-github-actions/workflow-syntax-for-github-actions#using-a-specific-shell
// Except for /D, which disables the AutoRun functionality from command prompt
// and it blocks Python virtual environment activation if one configures it in
// the previous steps.
toolRunnerCommandLineArgs = [
"/E:ON",
"/V:OFF",
"/S",
"/C",
"call",
"%programfiles(x86)%\\Microsoft Visual Studio\\2019\\Enterprise\\VC\\Auxiliary\\Build\\vcvarsall.bat",
"amd64",
"&",
"C:\\Program Files\\Git\\bin\\bash.exe",
"-c",
bashScript,
];
This is similar to how ci.ros2.org does it, but it's not exactly the same.

I tried to pass -DCMAKE_C_COMPILER=${CMAKE_C_COMPILER} and -DCMAKE_CXX_COMPILER=${CMAKE_CXX_COMPILER} as CMAKE_ARGS to ExternalProject_Add but it doesn't do much.

Are you able to actually get any Windows builds working using action-ros-ci? I tried to enable a test of that at #630 and failed - maybe I'm missing something.

christophebedard commented

It seems to work in some situations (e.g. Python packages and maybe simple C++ packages?), but overall it doesn't work well 😕

wmmc88 commented

I was trying to enable windows builds with action-ros-ci too and couldn't get builds to work. I replicated the commands the action calls locally and think i found the issue.

C:\Windows\system32\cmd.exe /E:ON /V:OFF /S /C call "%programfiles(x86)%\Microsoft Visual Studio\2019\Enterprise\VC\Auxiliary\Build\vcvarsall.bat" amd64 & "C:\Program Files\Git\bin\bash.exe" -c "c:/dev/foxy/ros2-windows/setup.bat && colcon build --event-handlers console_cohesion+" calls the setup.bat script from within a gitbash shell. the resulting environment doesn't have the required environment variables set and causes issues with finding cmake configs, etc: https://github.com/wmmc88/test-repo/runs/3713014678?check_suite_focus=true

ill try to submit a fix for it

with #712 and #719 merged, i think this is resolved?

christophebedard commented

Yep! I opened #725 for the testing part.
