Comment 2 Luya Tshimbalanga 2020-06-09 01:05:50 UTC
Thanks for the tracker. Similar problem occurs with upstream blender-2.83.0 from Rawhide scratch build result:

Comment 3 Petr Viktorin 2020-06-09 08:27:37 UTC
CPython issue on removing PyNoArgsFunction (which was undocumented, and undefined – only declared):

Comment 4 Igor Raits 2020-06-11 05:42:20 UTC

This is the first reminder (step 3 from

If you know about this problem and are planning on fixing it, please acknowledge so by setting the bug status to ASSIGNED. If you don't have time to maintain this package, consider orphaning it, so maintainers of dependent packages realize the problem.

Comment 6 Luya Tshimbalanga 2020-06-23 00:45:10 UTC
Spec file updated addressing the issue: Other issue occurred and need investigation.

Comment 7 Luya Tshimbalanga 2020-06-23 01:30:34 UTC
Now OpenImageIO and opencv are blockers.

Comment 8 Luya Tshimbalanga 2020-06-23 01:31:16 UTC
Scratch build result

Comment 9 Ben Cotton 2020-08-11 13:35:35 UTC
This bug appears to have been reported against 'rawhide' during the Fedora 33 development cycle.
Changing version to 33.

Comment 10 Miro Hrončok 2020-08-22 10:30:52 UTC
Hello. This comment is mass posted to all 16 bugzillas for packages that failed to rebuild with Python 3.9 (and, in most cases, also fail to install on Fedora 33 and 34). Apologies if some of the suggestions or questions don't apply 100%.

Fedora 33 Beta Freeze starts next week on Tuesday, 2020-08-25. I haven't spammed this bugzilla because it is in ASSIGNED, or I've seen upstream has been notified.

Please consider what to do here. Is this failure critical? For example, can a test be temporarily skipped to make this package build? Is it possible to fix or workaround the failure before Fedora 33 Beta? Or before Fedora 33 Final? If not, would it make sense to retire the package (even temporarily) before the release to unblock updates from Fedora 31 or Fedora 32?

In case you need any assistance with a Python-related problem with the build, don't hesitate to let me know and I'll try to have a look.

Thank you!

Comment 11 Charalampos Stratakis 2020-08-25 12:36:28 UTC
The current issue with building blender right now lies with openvdb, from which blender imports some headers [0]. It seems the workaround is to ensure that blender is built with c++14.
