I must admit that I don't understand that error at all.


For the build logs, see:
https://copr-be.cloud.fedoraproject.org/results/@python/python3.9/fedora-rawhide-x86_64/01139166-libcomps/

For all our attempts to build libcomps with Python 3.9, see:
https://copr.fedorainfracloud.org/coprs/g/python/python3.9/package/libcomps/

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 3.9:
https://copr.fedorainfracloud.org/coprs/g/python/python3.9/

Let us know here if you have any questions.

Python 3.9 will be included in Fedora 33, but the initial bootstrapping has already started.
A build failure this early in the bootstrap sequence blocks us very much.

Comment 1 Marek Blaha 2020-01-07 08:11:55 UTC

The Cmake files in this project are really messy and definitely deserve some work. Anyway, this PR at least fixes Python 3.9 builds: https://github.com/rpm-software-management/libcomps/pull/64

Comment 2 Miro Hrončok 2020-01-17 18:12:52 UTC

Current libcomps build fine with updated cmake: https://src.fedoraproject.org/rpms/cmake/c/8d55c35ecb54c581f2823c563d5d562aec02c2b9?branch=master
