$ rpm -q python3-pyqtchart
python3-pyqtchart-5.12-1.fc31.x86_64


>>> from PyQt5.QtChart import QChart, QLineSeries, QValueAxis
Traceback (most recent call last):

While on my Fedora 30:

I belive this is a regression that was wrongfully covered by https://src.fedoraproject.org/rpms/python-pyqtchart/c/a796712eb0ec2bc877875584f057793161e11ca5?branch=master - temporarily disabling the debug_package - in fact, the package did not link properly.

Installing qt5-qtcharts manually workarounds the issue.

I'm going to add the dependency manually to unblock bz1731655, but this should be solved properly.

Comment 1 Miro Hrončok 2019-07-20 15:13:28 UTC

Rex, any idea what could have caused this?

Comment 2 Rex Dieter 2019-07-20 20:56:34 UTC

Make sure your *.so files are executable, otherwise rpm won't autodetect library dependencies.  See python-qt5 example,

https://src.fedoraproject.org/rpms/python-qt5/blob/master/f/python-qt5.spec#_327

Comment 3 Miro Hrončok 2019-07-20 22:36:00 UTC

Any idea why they suddenly stopped being executable?

Comment 4 Rex Dieter 2019-07-21 06:18:14 UTC

I don't know the cause unfortunately

Comment 5 Miro Hrončok 2019-07-21 07:47:56 UTC

Thanks for the pointer anyway.
