Hi! This is the friendly automated conda-forge-linting service.

I just wanted to let you know that I linted all conda-recipes in your PR (recipe/meta.yaml) and found it was in an excellent condition.

I do have some suggestions for making it better though...

For recipe/meta.yaml:

  • ℹ️ The recipe is not parsable by parser conda-souschef (grayskull). This parser is not currently used by conda-forge, but may be in the future. We are collecting information to see which recipes are compatible with grayskull.
  • ℹ️ The recipe is not parsable by parser conda-recipe-manager. The recipe can only be automatically migrated to the new v1 format if it is parseable by conda-recipe-manager.

This message was generated by GitHub Actions workflow run https://github.com/conda-forge/conda-forge-webservices/actions/runs/21722236032. Examine the logs at this URL for more detail.

@finnagin this is almost working now. We are cross compiling from x86_64 to arm64 and therefore we can't compile the python *.py files to .pyc. What we do in Unix is to build a separate python for build platform (x86_64) and use that to compile the *.py files. Would you be able to look into doing that here?

Sure @isuruf! I'll take a look.

We are cross compiling from x86_64 to arm64 and therefore we can't compile the python *.py files to .pyc.

The Programs/_freeze_module.c tool already gets built and used as part of a normal CPython build, and it should be very close to being able to generate normal .pyc files (it's used for some internal build steps that don't require regular .pyc files).

A patch to adapt that to be usable here would be totally welcome upstream. Saves rebuilding the entire interpreter again.
