Godot can't find wine (Flatpak)

[bastil0]

Godot version:
3.3 (Flatpak version)

OS/device including version:
Ubuntu 21.04

Issue description:
Godot can't find wine for the rcedit command (Windows export). I tried to leave the wine option in the editor settings blank, I tried "wine", "/usr/bin/wine", ... When I click on browse I can't find it either, but it works if I run it in the terminal. It works in the normal download version of Godot but not in the Flatpak version so I think this is a permission thing.

Steps to reproduce:

• Install Godot via Flatpak
• Install wine
• Try to find and use it in an export

That's a normal limitation of flatpaks, they're sandboxed so they don't give you access to other system binaries. That's not something that we can fix in Godot sadly.

Ok, I understand. Would be helpful if the whole command would be printed in the output console to run the command by hand in the terminal as a solution.

It should be possible to implement support for rcedit with the Flatpak as long as WINE is installed on the host: flathub/org.godotengine.Godot#38

Closing in favor of flathub/org.godotengine.Godot#73, as Flatpak-specific issues should be tracked on that repository instead.

You shouldn't have to use host wine anymore, Godot should be able to use org.winehq.Wine.

Unfortunately the way it's currently distributed is as a base app, but Godot can choose to distribute its own Wine as an extension (similar to how I did in the Fightcade Flatpak: com.fightcade.Fightcade.Wine
