Hello,

If you feel that this output has mistakes, please open an issue at https://pagure.io/releng/

This package fails to install and maintainers are advised to take one of the following actions:

 - Fix this bug and close this bugzilla once the update makes it to the repository.
   (The same script that posted this comment will eventually close this bugzilla
   when the fixed package reaches the repository, so you don't have to worry about it.)

or

 - Move this bug to ASSIGNED if you plan on fixing this, but simply haven't done so yet.

or

 - Orphan the package if you no longer plan to maintain it.


If you do not take one of these actions, the process at https://docs.fedoraproject.org/en-US/fesco/Fails_to_build_from_source_Fails_to_install/#_package_removal_for_long_standing_ftbfs_and_fti_bugs will continue.
This package may be orphaned in 7+ weeks.
This is the first reminder (step 3) from the policy.

Don't hesitate to ask for help on devel.org if you are unsure how to fix this bug.

I have updated giacpy in the upstream git repository:
https://gitlab.math.univ-paris-diderot.fr/han/giacpy

there was more problems detected by the test suite due to cython >3.0.0 


mock-chroot> sh-5.2# python3
Python 3.12.0b4 (main, Jul 21 2023, 00:00:00) [GCC 13.1.1 20230614 (Red Hat 13.1.1-4)] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> from giacpy import giac
>>> a=giac('a') ; 1+a   # gave an error with giacpy 0.7.1 and cython3
1+a


I was able to build and run giacpy 0.7.2 on rawhide.
could you try to update the package?
