GDH not building

[Gamer069]

I wanna contribute to this project.
But obviously to do that, i need to at least BUILD it...
The errors i'm getting are

(i use arch btw)
...

and i don't wanna just comment these lines bc like they're static asserts.
and if i do, then i get an even nastier error (this time linker error):

BTW to build i'm just doing

geode build

(i do have a cross-toolchain setup or whatever)

[Gamer069]

and i understand that these errors are imgui-related but they still should be somehow fixed...

[TobyAdd]

mod compiles on last commits (tested on windows, msvc compiler)

[Gamer069]

it doesn't build properly on linux

[TobyAdd]

I sincerely apologize, but I don't know the status of mod compilation for Linux. You can use a virtual machine with Windows or utilize GitHub Actions. The only issue is that FFmpeg libraries for Android aren't distributed and must be compiled manually to get GDH working on Android.
