[PyQt] Missing libQt5Xml when running pylupdate

Tue Dec 31 07:09:37 GMT 2019

Hi again Phil,

I have been posting on stack overflow [0], and thanks to a reply, I can
give more precise input:

If you run ldd /usr/local/lib/python3.7/site-packages/PyQt5/
pylupdate.abi3.so, you see that it is badly linked to the system libraries:

Step 8/9 : RUN ldd /usr/local/lib/python3.7/site-packages/PyQt5/
pylupdate.abi3.so

For comparison,  while if you ldd
/usr/local/lib/python3.7/site-packages/PyQt5/QtCore.abi3.so
<http://qtcore.abi3.so/>, it is correctly pointing to the libraries in
site-packages.

Does it help to fix this issue?

Cheers,
Denis
