protongdb
A small little helper for running games with Proton and debugging with GDB
Requirements
- At least Python 3.5
- protontricks pip package and its dependencies (
pip install --user protontricks)
Usage
The basic usage is as follows:
On any Steam app that you have a prefix for (ie. started the game at least once) you can use
protongdb <appid> [args...]
to start it with a debugger.
You can find the appid for the game using the Properties > Updates tab of the game.
If the game crashes or you hit a breakpoint, you can run wine-reload to resolve any symbols, etc.
You can then get a backtrace or step-through the code like a native app.
Unlike Steam, environment variables are inherited from your environment, so specify them before protongdb (no need for %command% stuff).
Special Thanks
Thanks to the creators of protontricks as it had a lot of useful helper functions to make this work, and Rémi Bernon for the WineReload code.
