Let's get this building, we shouldn't merge it before we have updated it to a release candidate.

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.

The following error is related to the compiler update and also shows up in Python 3.13:

Pinning the compiler to GCC 13 leads to the same error, so it could also be related to the sysroot.
