run crash after building on Debian 10

[darckense]

I try to build knossos on Debian 10 following the building instructions and it crash when I launch it with ninja run.

I have the current versions of Debian 10 packages, that is:

• python 3.7.3
• pyqt5 5.11.3

Here is what happen:

darckense@lodoss:~/jeux/git/knossos$ ninja run
[0/1] RUN
INFO:MainThread:util.<module>: Deactivating pyOpenSSL...
INFO:MainThread:launcher.main: Running Knossos 0.14.2-dev+1f60d92 on PyQt5 and Python 3.7.3 (default, Jul 25 2020, 13:03:44)

Thank you,

Unfortunately, I can't tell from that alone what the error is. Can you run Knossos in gdb?
You can launch Knosss in gdb by running gdb python3 and then entering run /home/darckense/jeux/git/knossos/knossos/__main__.py.
Once it crashes, enter bt on the gdb prompt. That should print out a stacktrace which will tell us more about where the error ocurred.

To close gdb afterwards, enter quit.

Hi, thanks for your reply.

Here is the output of the command:

Looks like /usr/lib/x86_64-linux-gnu/qt5/plugins/platformthemes/KDEPlasmaPlatformTheme.so is initializing KDE's KCrash library (/lib/x86_64-linux-gnu/libKF5Crash.so.5) which then fails with corrupted double-linked list.

I'm not sure what's causing the issue. Can you try again with QT_QPA_PLATFORM set to an empty string? (So basically QT_QPA_PLATFORM= gdb and then the same commands as before)

I want to make sure that this is an issue with Knossos and not KDE.

I'm not sure if I have done it right, but here is the result of :

$ QT_QPA_PLATFORM=
$ gdb python 3
(gdb) run /home/darckense/jeux/git/knossos/knossos/__main__.py
(gdb) bt
