Allow multiple build for different type of OS.

@jakemac53 – is there a way to set this up w/ mono_repo?

[irvifa]

If it’s possible then will be good since we don’t need to create an explicit matrix. Expect we of course still can exclude several things that don’t need to be build inside of the job.

[jakemac53]

mono_repo does support os config yes. It looks just like normal travis config, so inside of a mono_pkg.yml file you would do for instance:

os:
  - linux
  - windows
  - osx

[irvifa]

For travis I guess there's also a problem for the Windows dll build, for FFI samples. However I can't test it on my PC. Please see https://travis-ci.org/github/dart-lang/samples/jobs/670278306?utm_medium=notification&utm_source=github_status

As for mono_repo I try to change the following:

travis:
  addons:
    apt:
      packages:
        - cmake

  os:
    - linux
    - osx
    - windows

But seems like the expansion didn't work for all of the os. https://travis-ci.org/github/dart-lang/samples/builds/670381077?utm_source=github_status&utm_medium=notification. Let me know if there's still something off with the config. Thank you..

I believe this is the start of a fix for #46

[irvifa]

@domesticmouse Yes it is.. the build config that managed to fix this is writing all of the possible combination for all of the build stages. But this is really inefficient, in the term of lines addition. The goal is since this is something like "Hello World" I hope people can easily look at the working example. Any documentation on how mono_repo config works? I'm never use that before. Example of fixes related to FFI is including #44.

Hey @kevmoo, can you help out with configuring mono_repo?

[jakemac53]

@irvifa The os config is a top level thing that you put in each mono_pkg.yaml file - it doesn't go under the travis section.

You can see an example here https://github.com/dart-lang/build/blob/280cd60d74fe24e5a2f01032f4c5ffe3e9c4c5a6/_test/mono_pkg.yaml#L4 which also has examples of overriding specific tasks to run only on a certain os.

[irvifa]

@jakemac53 I think that's because of the fact that top level mono_repo is https://github.com/dart-lang/build/blob/280cd60d74fe24e5a2f01032f4c5ffe3e9c4c5a6/mono_repo.yaml So the mono_repo you mentioned before linked to the top level mono_repo, please cmiiw..

[jakemac53]

@irvifa I am not sure what you are asking exactly - but what you need to do is put the os configuration in each nested mono_pkg.yaml file - you configure that per package even if its the same for every package. It is not supported in the mono_repo.yaml file as a global option.

[irvifa]

@jakemac53 Can you help me review this PR? I exclude the windows as allowed to fail since I can't exactly test the .dl lib in windows for FFI. Wondering if opening .dl is allowed in Windows by default.

[jakemac53]

I can send an alternate PR here to show what I mean about the config, give me a minute.

You can also choose which jobs should run on which OS instead of allowing all failures on osx/windows.
