pybind11 fails to build with Python 3.11.0a7. ImportError while loading conftest '/builddir/build/BUILD/pybind11-2.9.2/tests/conftest.py'. ../../tests/conftest.py:19: in <module> import pybind11_tests # noqa: F401 E ImportError: VanillaDictMix1: PyType_Ready failed (TypeError: mro() returned base with unsuitable layout ('pybind11_tests.multiple_inheritance.WithDict'))! This seems to be connected with this change in CPython: The PyType_Ready() function now raises an error if a type is defined with the Py_TPFLAGS_HAVE_GC flag set but has no traverse function (PyTypeObject.tp_traverse).

You can follow these instructions to test locally in mock if your package builds with Python 3.11: https://copr.fedorainfracloud.org/coprs/g/python/python3.11/ Let us know here if you have any questions. Python 3.11 is planned to be included in Fedora 37. To make that update smoother, we're building Fedora packages with all pre-releases of Python 3.11. 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.
I don't have the time nor the expertise to work on this. If anyone is willing to take pybind11 off my hands, please tell me.
CCing some people who might be interested in taking over pybind11. pybind11 is needed for scipy, opae, and zxing-cpp in ELN. In Rawhide, it is needed for more: $ repoquery -q --repo=rawhide{,-source} --whatrequires pybind11-devel --whatrequires python3-pybind11 OpenColorIO-0:2.1.1-3.fc37.src OpenImageIO-0:2.3.14.0-1.fc37.src android-file-transfer-0:4.2-4.fc36.src arbor-0:0.5.2-4.fc36.src dolfin-0:2019.1.0.post0-30.fc36.src gnuradio-0:3.10.2.0-1.fc37.src gr-air-modes-0:0-0.93.20200807git9e2515a5.fc37.src gr-funcube-0:1.0.0-12.20220130gitbf71b979.fc37.src gr-hpsdr-0:3.0-12.fc37.src gr-iqbal-0:0.38.2-13.20210210gitfbee239a.fc37.src gr-osmosdr-0:0.2.3-22.20210217gita100eb02.fc37.src gr-rds-0:1.1.0-30.20220127git51acc5bd.fc37.src libsonata-0:0.1.11-6.fc37.src morphio-0:3.3.3-1.fc37.src netgen-mesher-0:6.2.2202-1.fc37.src oneVPL-0:2022.1.0-1.fc37.src opae-0:2.0.0-2.8.fc36.src openshadinglanguage-0:1.11.16.0-3.fc36.src orocos-kdl-0:1.5.1-1.fc37.src psi4-1:1.3.2-13.fc35.src pyosmium-0:3.3.0-1.fc37.src python-ducc0-0:0.23.0-1.fc37.src python-mapbox-earcut-0:1.0.0-1.fc36.src python-mplcairo-0:0.4-4.fc36.src python-pikepdf-0:5.1.0-1.fc37.src python-pyopencl-0:2022.1-1.fc37.src python3-dolfin-0:2019.1.0.post0-30.fc36.x86_64 python3-pybind11-0:2.9.2-1.fc37.x86_64 scipy-0:1.8.0-3.fc37.src smoldyn-0:2.66.1-2.fc36.src xcfun-0:2.1.1-5.fc36.src xtensor-python-0:0.24.1-5.fc36.src xtensor-python-devel-0:0.24.1-5.fc36.i686 xtensor-python-devel-0:0.24.1-5.fc36.x86_64 zxing-cpp-0:1.2.0-3.fc36.src
Closing this in bulk as it built with Python 3.11. If this needs to remain open for a followup, feel free to reopen, I won't close in bulk again.
