CI failing on platforms outside x86-64

[djmitche]

I have a workflow created from maturin generate-ci github (and subsequently trimmed down to fewer jobs while trying to figure out what's wrong), in GothenburgBitFactory/taskchampion-py#3:

name: CI

  push:
    branches:
      - main

        with:
          subject-path: 'wheels-*/*'
      - name: Publish to PyPI
        if: ${{ startsWith(github.ref, 'refs/tags/') }}
        uses: PyO3/maturin-action@v1
        env:
          MATURIN_PYPI_TOKEN: ${{ secrets.PYPI_API_TOKEN }}
        with:
          command: upload
          args: --non-interactive --skip-existing wheels-*/*

and it fails, for every platform bug x86-64, with

error: failed to run custom build command for `pyo3-ffi v0.22.6`

Caused by:

  --- stderr
  error: the Python interpreter was built with the GIL disabled, which is not yet supported by PyO3
  = help: see https://github.com/PyO3/pyo3/issues/4265 for more information
  = help: please check if an updated version of PyO3 is available. Current version: 0.22.6
  = help: set UNSAFE_PYO3_BUILD_FREE_THREADED=1 to suppress this check and build anyway for free-threaded Python

I don't have any intention to build against disabled-GIL Python's and have no special configuration for that, so I assume this is something in the maturin action or the version of maturin I'm using?

Should be fixed by #2413 so that python3.13t is not used with pyo3 < 0.23. You can use -i option to specify the python versions you want to support instead of --find-interpreter to workaround it ATM.
