pynac fails to build with Python 3.10.0a7.

configure: error: cannot import Python module "distutils".
Please check your Python installation. The error was:
<string>:1: DeprecationWarning: The distutils package is deprecated and slated for removal in Python 3.12. Use setuptools or check PEP 632 for potential alternatives

bpo-41282: Deprecate distutils in documentation and add warning on import.

For the build logs, see:

For all our attempts to build pynac with Python 3.10, see:

Testing and mass rebuild of packages is happening in copr. You can follow these instructions to test locally in mock if your package builds with Python 3.10:

Let us know here if you have any questions.

Python 3.10 will be included in Fedora 35. To make that update smoother, we're building Fedora packages with early pre-releases of Python 3.10.
A build failure prevents us from testing all dependent packages (transitive [Build]Requires), so if this package is required a lot, it's important for us to get it fixed soon.
We'd appreciate help from the people who know this package best, but if you don't want to work on this now, let us know so we can try to work around it on our side.

m4/ax_python_devel.m4 is outdated, it needs to contain this fix from 2017:;a=commit;h=883a2abd5a

Comment 2 Jerry James 2021-04-12 17:34:34 UTC
Upstream git head no longer contains m4/ax_python_devel.m4.  There is also a pull request to use setuptools to build the extension module.  Since this seems to be an issue for version 0.7.26 only, I am going to simply refresh m4/ax_python_devel.m4 from autoconf-archive for now, and test that the problem stays fixed when the next version is released.

Thanks, Jerry!
