Description Miro Hrončok 2019-08-29 11:45:24 UTC 
python-pywt fails to build with Python 3.8.0b3 in Fedora 32 on ppc64le.

See the build failures at https://koji.fedoraproject.org/koji/search?match=glob&type=package&terms=python-pywt

======================================================================

It is not important whether the problem is relevant to Python 3.8, this issue is blocking the Python 3.8 rebuilds.
If this package won't build with 3.8, it won't be installable, along with all its dependent packages, in Fedora 32 and further.

Furthermore, as it fails to install, its dependent packages will fail to install and/or build as well.

Please rebuild the package in Fedora 32 (rawhide).

Let us know here if you have any questions. Thank You!
