Qt Designer can't be used
Every time I start the Qt Designer and want to create a new Main Window, the window of the Qt Designer is closed when I click the create button and nothing else changes. I have a Manjaro Linux. Does anyone can help me?
Do you mean the stand alone Designer app ?
Not QtCreator and its designer plugin but the real alone Designer ?
I think it's the alone Qt Designer, I downloaded pyqt5-tools and there was the Qt Designer.
Ok if its for use with python, i also think its the standalone one that.
Try to start it from a shell and see if it writes something.
It sounds like it plain crashes.
This came in the terminal:
/home/dominikb/.local/lib/python3.8/site-packages/pyqt5_tools/Qt/bin/designer: symbol lookup error: /home/dominikb/.local/lib/python3.8/site-packages/pyqt5_tools/Qt/bin/designer: undefined symbol: _ZdlPvm, version Qt_5
I think it might find the wrong version of something.
Could you check in Designers folder if it has a .sh file to start it.
There was one at a time that would make sure the right libs was seen.
I can't find the Designers folder and the path which came in the shell somehow doesn't exist.
This comes in the shell when I start the designer:

and then if I click the create button to create a Main Window, it returns that what I've already posted.
I think its related to incompatible libstdc++ as far as i understand it but
i dont know how to fix it.
What version of Manjaro are you using ?
Linux 5.7.17-2-MANJARO x86_64 20.1 Mikah
I will use now the designer in the Qt Creator because it works there but thanks for your help.
I did not find anything with MANJARO but it seems that Mikah is pretty new so i wonder if the
libstdc is simply too new or something like that.
In any case, if you are using the version in Creator then at least there is a solution :)
