gcompris-qt segfaults #267

Closed tpapp closed 3 years ago

tpapp commented 3 years ago

I compiled from the master branch of the Github repo, and when I try to run it in QT creator, I get

16:42:43: Starting /home/tamas/src/build-GCompris-qt-Desktop-Debug/bin/gcompris-qt ...
QML debugging is enabled. Only use this in a safe environment.
exeCount set to:  1
16:42:43: The program has unexpectedly finished.
16:42:43: The process was ended forcefully.
16:42:43: /home/tamas/src/build-GCompris-qt-Desktop-Debug/bin/gcompris-qt crashed.

I am using Ubuntu 20.10. Happy to provide more debugging info (but please give detailed instructions as I am unfamiliar with QT Creator).

hi, thanks for the report. It may be some missing packages, but hard to tell with this trace only.

You can compile it directly on command line. Going into the source folder, do:

cd ~/src/gcompris-qt (where you cloned the code)
mkdir build
cd build
cmake ..
make -j 2
./bin/gcompris

Maybe there will be more traces on the console that will be useful.

If not, you can run it with gdb:

gdb ./bin/gcompris-qt

and type r to run GCompris. then, once it fails, type bt (backtrace), and copy paste the result here. To quit gdb, type q.

Thank you!

According to https://bugs.launchpad.net/ubuntu/+source/gthumb/+bug/1903569, it may be a driver issue, can you try to install intel-media-va-driver-non-free (apt install intel-media-va-driver-non-free) and check if it works better?

tpapp commented 3 years ago

Thanks, this fixes the issue. If you think that this does not have to do with gcompris, feel free to close, I am not able to determine.

petitlapin commented 3 years ago

Yes, it's not a GCompris issue. Great to hear it works better! Have fun
