[Enhancement]: Native Linux

[ThisNekoGuy]

Describe the new feature or enhancement

I'm aware MelonLoader can be used with Wine but can native Linux support become a project goal so that this isn't a hard requirement anymore? It's irritating to want to support developers who actually care about (us) Linux users, and they therefore give good Linux builds (The Long Dark, for example), then we as the end-users get pigeon-holed into not using those builds they spent time and effort on just because we want to make/use mods. (I'm personally bringing this up because I wanted to write a mod, as an [Arch] Linux user, and am running into this explicit issue.)

[D2Lx0wse]

But this already has linux support, as of latest release (https://github.com/LavaGang/MelonLoader/releases/tag/v0.6.1)

[ThisNekoGuy]

@D2Lx0wse I was under a very different impression from the docs :v

[D2Lx0wse]

yeah someone should start updating them

[D2Lx0wse]

I would but idk how the linux version works and idk if I would have time

[SamboyCoding]

Yeah there is a native linux version. Docs just haven't been updated.

[RinLovesYou]

(Linux support is still a little scuffed, hence the missing documentation. Current procedure is relatively easy, install .net 6, and load Melonloader's proxy with LD_PRELOAD. cpp2il needs to be manually chmodded)

[ThisNekoGuy]

cpp2il needs to be manually chmodded

~~@RinLovesYou Can you clarify that part for me? Apparently the Linux build of The Long Dark uses il2cpp2? It threw this error window when I tried to load the library: Screenshot_20230429_010342~~

EDIT: Wait, I thought I had dotnet6 installed; after installing it and trying again, the game window is just transparent for some reason

It seems, in the log, it's complaining about a permissions failure (why would it want root permissions?) (it apparently wasn't set to executable):

[ThisNekoGuy]

Should this be a seperate issue?

[SamboyCoding]

cpp2il needs to be manually chmodded

[ThisNekoGuy]

@SamboyCoding I figured that out already, that's no longer the issue The problem is that cpp2il crashes
