[solved] Installation Problems on Linux Nobara (Fedora)

Hello,

I switched from Windows to Linux and I am trying to get my QCAD Pro running. I can install it but it hangs when trying to start it up. I've tried all of the installers from version 3.27.8 and 3.30.1.

The problem seems to be Wayland. With the main installer I get errors similar to this thread: https://www.qcad.org/rsforum/viewtopic. ... dow#p39921. With the qt 5.14 installer I get errors similar to this thread: https://www.qcad.org/rsforum/viewtopic. ... ort#p37961.

I did try the newest version (3.32.4) of the community edition and that works.

Is there any way to get either version of QCAD Pro above to work? Maybe copy/paste a file from 3.32.4 into 3.30.1pro? Any ideas?

Fixed it by running the qt5.14 version from the terminal using the following line:

Code: Select all

 QT_QPA_PLATFORM=xcb LD_LIBRARY_PATH=. ./qcad-bin
You might need to install Qt for the QT_QPA_PLATFORM variable to work but maybe not.
