I'm trying to release my game for Win/Mac/Linux on Steam. On Windows, it works fine. On Linux, the Steam overlay doesn't show up even though the Greenworks plugin is able to get my user ID.
I followed the steps listed here: https://www.construct.net/en/make-games/addons/84/greenworks/documentation
* The steam_app_id.txt file contains my app's ID. I tried to save it in ANSI encoding but I can't be 100% it's the right encoding.
* I used chmod a+x on the two Steam API .so files.
* I downloaded my game, and overwrote its download folder with this minimal test project so I could launch it from Steam.
I know you can't run this project in Steam, but I don't suppose anyone can see anything clearly wrong with this project?
You can download the c3p file and output here: https://www.dropbox.com/s/nk4li6q1di8pw8p/steamtest.zip?dl=0
Has anyone else gotten the Steam overlay to work on Linux? Did you need to do anything different besides what's in the linked tutorial above?
