This document is intended for people who are used to working with games natively running on Windows and want to use familiar tools.
Starting Proton 9 every released build (includes stable and experimental) the build is uploaded to a symbol store. Any tool that can understand those (e.g. Visual Studio, WinDbg) can be pointed to https://proton-archive.steamos.cloud/.
- After opening a minidump in Visual Studio you need to click on "set symbol paths" or click Tools -> Options -> Debugging -> Symbols. This is global and needs to be done only once.
- Click on the plus button and add https://proton-archive.steamos.cloud/.
- Close the Options Window and proceed to any debugging action as you would normally do. You should see symbols being loaded from the just added location.
- Debugging should now work just like the native one including call stack, variables, etc. Too see the Wine/Proton part of callstack you can select "show external code".
- Click File -> Settings -> Debugging Settings
- Enter
srv*https://proton-archive.steamos.cloud/in the "symbol path" field.
- Debugging should now work just like the native one including call stack, variables, etc.
For loading dev builds of games onto a Steam Deck see https://partner.steamgames.com/doc/steamdeck/loadgames
For live debugging see https://partner.steamgames.com/doc/steamdeck/debugging
For best results either add a symbol server to Visual Studio as described above or use a debug build of Proton.
Debug builds contain symbols and should be used for live debugging session.
- Locate the version of proton you are using in your Steam Library (e.g. Proton Experimental), click on a cog and select properties.
- In the "betas" tab select "debug - unstripped".
- Chosen Proton version will now download and update and the symbols will be available.
