Description Karolina Surma 2023-11-21 12:55:48 UTC
netcdf4-python fails to build with Python 3.13.0a1.

This report is automated and not very verbose, but we'll try to get back here with details.

+ /usr/bin/python3 run_all.py
Traceback (most recent call last):

For the build logs, see:
https://copr-be.cloud.fedoraproject.org/results/@python/python3.13/fedora-rawhide-x86_64/06660889-netcdf4-python/

For all our attempts to build netcdf4-python with Python 3.13, see:
https://copr.fedorainfracloud.org/coprs/g/python/python3.13/package/netcdf4-python/

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 3.13:
https://copr.fedorainfracloud.org/coprs/g/python/python3.13/

Let us know here if you have any questions.

Python 3.13 is planned to be included in Fedora 41.
To make that update smoother, we're building Fedora packages with all pre-releases of Python 3.13.
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.

Comment 1 Miro Hrončok 2023-11-21 14:11:13 UTC
https://src.fedoraproject.org/rpms/netcdf/c/9b712ed0c1c3ab90bae52ca58de5f389c795d3dd?branch=rawhide updated netcdf from 4.9.0 to 4.9.1

The certifi import in netcdf4-python-1.6.5rel/src/netCDF4/_netCDF4.pyx is:

----------------------------------------------------------
IF HAS_NCRCSET: # available starting in version 4.9.1
    import certifi
    ...
----------------------------------------------------------

Hence I strongly belive this is caused by the netcdf update and not Python 3.13.

Comment 2 Miro Hrončok 2023-11-21 14:49:53 UTC
Yes, https://koschei.fedoraproject.org/package/netcdf4-python confirms that.
