Error on executing steam proton app via command-line

  • 772

I'd like to launch a proton app installed via steam but without using steam.

the point being I can make my own command-line launcher and pass parameters etc...

since I'm entirely new to this I don't know by which horn to grab the bull.

will I be able to course through steam's lib or will I be forced to install my own separate version of proton?

Here's the system info steam gathered of my system :

Recent Failure Reports:

The specific game I'm trying to run is Supreme Commander Forged Alliance and it runs fine via steam.

I don't know why people have been giving it garbage steam play reports on the steam play compatibility site but personally; it runs perfectly:

https://spcr.netlify.com/app/9420

all I have to do is press alt-F4 two times and wait a lot to trick the main menu into showing up and past the main menu there are no bugs at all the in-game experience is fluid and stable.

but yeah, that game's entire online community is on FAF not on steam, both FAF python and FAF java run naively on Linux nowadays for the final key is getting java-FAF to make the correct proton calls to Forged Alliance for the game to fully work :)

Guide to get to where I'm at :

To install FAF :

cd /faf

and run FAF :

downlords-faf-client

or

./downlords-faf-client

now you should have FAF started. If you do not have an account you may create one.

after this, you can go into FAF's settings and there you can configure run folder and run arguments for FA.

Update :

I've since made a guide for how to set up FAF : https://www.youtube.com/watch?v=Rv3ZXA4FNFk

    Proton/SteamPlay's wine is located in ~/.local/share/Steam/steamapps/common/Proton*

    Your game's wineprefix is located in ~/.local/share/Steam/steamapps/compatdata/$appid/pfx, you can find the $appid in ~/.local/share/Steam/steamapps/common/$your-game/steam_appid.txt (to use it, set the WINEPREFIX environment variable to that path)

    Edit: Your game files are located in ~/.local/share/Steam/steamapps/common/$your-game

    To run a *.exe file with Proton you can use the following commands:

    Change working directory to Proton's:

    cd ~/.local/share/Steam/steamapps/common/Proton*

    Run the executable, for example:

    STEAM_COMPAT_DATA_PATH="$HOME/.local/share/Steam/steamapps/compatdata/$appid" ./proton run dist/lib/wine/fakedlls/cmd.exe

  2. You need to create ~/.proton. It can be any directory and can be empty.

    On the command-line you can use:

    mkdir ~/.proton
