Description Miro Hrončok 2019-06-03 14:36:50 UTC 
See https://copr.fedorainfracloud.org/coprs/g/python/python3.8/package/pidgin/ for actual logs. This report is automated and not very verbose, but feel free to ping me for help.
Comment 1 Jaroslav Škarvada 2019-06-03 23:26:13 UTC 
It looks like python3.8 problem:
$ python3-config --libs
 -lcrypt -lpthread -ldl  -lutil -lm -lm 

With python3.7:
$ python3-config --libs
-lpython3.7m -lcrypt -lpthread -ldl  -lutil -lm 

I.e. -lpython3.8m is missing, not counting that -lm is there two times.
Comment 2 Miro Hrončok 2019-06-03 23:37:33 UTC 
-lpython3.8 missing is a deliberate change in 3.8, see https://docs.python.org/dev/whatsnew/3.8.html#debug-build-uses-the-same-abi-as-release-build

-lm being there two times is because we have reverted a downstream only patch that was supposed to remove duplicates there but was too greedy and broke other things, should be harmless.

If I understand the use case in pidgin correctly, it should use:

$ python3-config --libs --embed
