Debugging Snap Segmentation Fault of Hypnotix app

snap
1

Trying running my build of Hypnotix in snap results in segmentation fault:

user@hp-laptop:~$ hypnotix
Segmentation fault (core dumped)

Is there a way to debug the issue (I’ve tried gdb but it doesn’t seem to target the actual binary)? The app works fine without snap.

My manifest is as follows:

name: hypnotix

You can try to follow this guide: Using gdb and gdbserver This should at least give you a backtrace. In any way, since you got a segfault and a coredump, you should be able to inspect that even without invoking the snap.

I faced the same, and even the upstream didn’t help back then. So, I simply stopped working on it. This is my yaml file

Give it a try by modifying it. It also doesn’t uses any manual repo
