Problems with Qt5

Post by Joseph-Cousteau »

Good morning!
I tried in vain today to use code saturne; it worked great, but days ago i installed (and then removed) spyder5 by pip.
since then, I started to have issues with PyQt5 and Qt5 :(
After typing the command

Code: Select all

code_saturne gui
in the terminal, this appeared:

Code: Select all

user@my_laptop:~$ code_saturne gui
Cannot mix incompatible Qt library (5.15.2) with this library (5.15.3)
Aborted (core dumped)
I am using Code Saturne 8.03 on Xubuntu 22.04 LTS
How can i fix it?

The error message explains it all.

If you follow the recommendations on the Wiki here ( ... n-packages), you do not need to use pip to install PyQt.

Only use pip if you understand its behavior well enough : unless you force the version number, a reinstall may install a more recent version.
If that happens, you simply need to reinstall code_saturne so as to relink-it with the correct version.

This can also occur using standard packages on a rolling Linux release, such as Arch. But in that case it should not come as a surprise, as developers using rolling releases usually expect this to occur occasionally so are not surprised.

Best regards,
