[Linux] No Guy's Sky not loading in Zandronum

[CrimCuttle]

I want to play No Guy's Sky, but I get a weird error message when I try to play it.
Here's what I do to get WADs to work on singleplayer:
1.) Open Doomseeker's Create Server menu
2.) Add the ngs.pk3 file into the "additional WADs" list
3.) Click "play offline"
And here's the following text that appears in my terminal when attempting to run it.

Can anyone help me fix this?

I realize that this might be in the wrong place.
Can a mod move this if possible?

This runs in GZDoom. It may not run in Zandronum.

Ah dammit, there's no GZDoom for Linux...

[enderandrew]

Try ZDoom. GZDoom is a fork of ZDoom with OpenGL support.

Yes there is GZDoom on Linux.

That said NGS did bad things that will probably break eventually. Stuff like that:

Tried to register class 'Fist' more than once.

Bad! Very bad!

Woah, what?! I never saw this before...

Well, how do I make it not do bad things?

Basically the problem is that it defines a class with the same name as a core class (Fist in this case) so the engine has to decide whether "Fist" refers to the first Fist or the second Fist. This is a recipe for disaster.

The solution would be to edit the mod, find where it defines Fist, and rename it to something else (like NGSFist for example) and then look where it uses it and update to the new name.
