QT5.15 dependency issue during launching


I have a question about the QT5.15 during launching.

Traceback (most recent call last):
File “/home/bo/Downloads/SALOME-9.9.0-native-UB20.04-SRC/BINARIES-UB20.04/GUI/lib/python3.8/site-packages/salome/salome_pluginsmanager.py”, line 94, in
import SalomePyQt
ImportError: /lib/x86_64-linux-gnu/libQt5Core.so.5: version `Qt_5.15’ not found (required by /home/bo/.local/lib/python3.8/site-packages/PyQt5/QtCore.abi3.so)

I installed QT5.15 in another folder, added its path to LD_LIBRARY_PATH, and made it default. Checking “qmake -v” did show the correct version (5.15.2). Do you have any suggestion on this issue?


SALOME 9.9 built on Ubuntu 20.04 uses Qt 5.12 which can be installed with apt package utility.

IMHO, you should simply either install the system dependencies which can be listed with : /sat config SALOME-9.9.0-native --check_system
or use the universal distribution which ships these dependencies.


Thank you for your suggestion!
