[schonfinkel]

Summary

• Closes Can't start the demo client #82

it almost works, I just need to add the assets to the build as well.

Testing

1. nix build .#client
2. ./result/bin/lyceum-client

@z-silver @EduardoLR10 I'm putting the assets in same directory ($out) as the executable.

@carlotm @ratsclub can you test this version later?

@schonfinkel same crash. tried on two different laptops with Debian 12.

@schonfinkel Progress!

Run the client crashes as before, but I was able to run the client with this command:

nix run --impure github:nix-community/nixGL -- ./result/bin/lyceum-client

I have found out that OpenGL apps have issues on non-nixos OSes.
More info at https://github.com/nix-community/nixGL

However, I don't see the assets, same as the screenshot you posted

Cheers!

[schonfinkel]

@carlotm great to know! The missing assets are part of another bug when running a pure client build, it seems, but that's progress! 🚀

I'll see if it is possible to integrate nixGL into our flake, so it becomes part of the devenv.

[schonfinkel]

@carlotm Sorry for taking this long, I've tested the pure client build and it works now, may you try it? Depending on your answers I may be able to drop the wrapProgram altogether as well (also summoning @ratsclub to test this on debian as well).

@z-silver @EduardoLR10 please review these changes.

Commands

To reproduce my results in this branch:

1. nix build .#client
2. ./result/bin/lyceum-client or nix run --impure github:nix-community/nixGL -- ./result/bin/lyceum-client

[EduardoLR10]

LGTM

[z-silver]

I got the same result as @carlotm - just running the executable failed (with the same error that he got), but nix run --impure github:nix-community/nixGL -- ./result/bin/lyceum-client works for me.

I got the same result as @carlotm - just running the executable failed (with the same error that he got), but nix run --impure github:nix-community/nixGL -- ./result/bin/lyceum-client works for me.

I confirm, just FYI.
