Migrated issue to PUP-12031

Hi,
I think this is a good path forward that was also requested multiple times in the past, specifically from people that package Puppet for some distributions (like I do for Arch Linux). I don't have a strong opinion on the two different approaches. A single gemspec feels a bit more natural to me. I would put all data in a single gemspec file and track the desired platforms in another file next to the gemspec, so you can just iterate on it in the pipeline.

Agreed, we're investigating this approach. It also means the Gemfile doesn't need to change, since gemspec will include the one and only gemspec.

Fixed in #9325

The gem build puppet.gemspec command now works as expected. It's also possible to build platform specific gems, for example gem build --platform x64-mingw32, even when running on a different platform.

And there is a rake task (rake pl_ci:gem_build) to build "all the gems", so that if/when we add new platforms like those based on ucrt.
