Game crashes when saving after first level

[Silicomancer]

I played the game (latest flatpak) on Kubuntu 22.04 using keyboard. When finishing the first level, a list of empty entries for game saving appeared. I pressed the Return key to save the game. The game crashed which means it disappeared immediately without any error message.

This is the end of the game log:

-> Load Level : jungle.map successful ! <-

Hard to tell without a backtrace. Even if the save location is read only it should not crash. Can you check the "Using save path" from the log?

[Silicomancer]

Sure, I am glad to help:

--> Using external config path '/home/myusername/.var/app/io.github.hurricangame.hurrican/config/hurrican' <--
--> Using external storage path '/app/share/hurrican/' <--
--> Using save path '/home/myusername/.var/app/io.github.hurricangame.hurrican/data/hurrican' <--

The save path does exist. And it contains only one file named "Hurrican.hsl" (size 480 byte).

Is there a way to get the backtrace?

[drfiemost]

You should run the app through gdb then use the bt command to print a backtrace after the crash, instructions here: https://docs.flatpak.org/en/latest/debugging.html

It would be very useful, I'm not able to reproduce the crash.

flatpak run --command=sh --devel io.github.hurricangame.hurrican
Error: runtime/org.freedesktop.Sdk/x86_64/22.08 is not installed

I guess I need to install that SDK first? Like this?

flatpak install flathub org.freedesktop.Platform//22.08 org.freedesktop.Sdk//22.08

[drfiemost]

Yes, it includes gdb among other things. I think you also need to install the hurrican .Debug package if available.

[Silicomancer]

Still something wrong:

Succeeded: flatpak install flathub org.freedesktop.Platform//22.08 org.freedesktop.Sdk//22.08

Succeeded: flatpak install flathub io.github.hurricangame.hurrican.Debug

Failed:

flatpak run --command=sh --devel io.github.hurricangame.hurrican.Debug
bwrap: execvp sh: No such file or directory

[Silicomancer]

Anyway starting flatpak without ".Debug" worked. This is what I got:

Does this help?

[drfiemost]

Yes thanks! I can see the problem now, will hopefully push a fix over the weekend.

BTW the debug package only contains debugging symbols, it's not an executable.

[drfiemost]

Fixed! @Silicomancer thanks for taking the time debugging the issue @thrimbor can you please update the flatpack build?

[thrimbor]

Done.

[Silicomancer]

Works for me now. Thank you!
