QCAD on Ubuntu 22.04.1 crashes

[asala]

PC with 6.2.0-34-generic #34~22.04.1-Ubuntu SMP PREEMPT_DYNAMIC Thu Sep 7 13:12:03 UTC 2 x86_64 x86_64 x86_64 GNU/Linux

First I installed QCAD trial version: all right, no issues.
Then I purchased the PRO version, downloaded qcad-3.28.2-pro-linux-x86_64.run, made it executable and run from a terminal window. Apparently the installation was OK. No errors

But starting it I get the splash screen, then nothing. Running ./qcad from terminal window I get
~/opt/qcad-3.28.2-pro-linux-x86_64$ ./qcad
QCAD version 3.28.2

QCAD has unexpectedly quit.

Please use the offscreen or minimal platform plugin for headless systems
(without a running X11 server):
./qcad -platform offscreen

In addition, you might have to override the default Qt style
to prevent the loading of a native desktop style (such as GTK):
./qcad -style plastique


BTW, the trial version keeps working correctly

What should I do ?

Thank you and best regards

Hi, and welcome to the QCAD forum.

Similar crash report with solution here:
https://www.qcad.org/rsforum/viewtopic.php?f=34&t=9490

I would remove the trial version first.

Please try the installer "qcad-3.28.2-pro-linux-qt5.14-x86_64.run" instead (labeled "QCAD Professional 3.28.2 for Linux Qt 5.14 64bit (Installer)" on your download page).

This version seems OK. Let me check it thoroughly
Thank you for your support

Yes, it seems the same problem with the same solution, and it works. Thank you
BTW I uninstalled the trial version but... things don't change. The solution is to use qt5 version.

Best regards

PC running Mint LMDE 6 (based on Debian 12) , kernel 6.1.0-18-and64 x86_64
Qcad 3.24.3

I recently changed OS from Mint 20.3 to Mint LMDE6. version 3.24.3 was running good on 20.3. Reinstall using the 3.24.3 .run file seemed to go ok , no errors reported. When I tried to start qcad there was no splash screen, only a qcad label showed in the panel for a few seconds before disappearing. Qcad did not start. Thinking it might be a PATH issue I added the install directory location to the path. Now when starting from the icon I get a splash screen for a few seconds then nothing. Starting from command line I get the same string of error messages as Asala reported in this thread.

I don't have a trial version to delete. I have previous versions of qcad going back to 3.16.2. I do not have an installer for 3.24.3 with qt5 in the label.

If qt5 is somehow part of the fix how do I get there from here?

Thank you.

@j22,

Version 3.24.3 is over 4 years old.
I don't think that there is still support for that.

You could renew your licence and update to the latest version.
On your personal download page (Or on the trial page) scroll further down beyond 'All Downloads'.
