Unable to build/use on NixOS

I wanna try this on NixOS but I couldn't.

install via flake

Build fail.

install via prebuild binary

Build success but unable to launch. Error log

The nix flake is user contributed and I do not have the ability to support it as I don't use nix. I would happily accept a PR that fixes this.

[RAVENz46]

Fortunately, the source build went well, but I get this error. If you have any ideas on how to fix it, I would appreciate hearing from you.

Are you using an Nvidia GPU? You could try forcing Vulkan/OpenGL by setting SIMP_GPU_BACKEND=vulkan or SIMP_GPU_BACKEND=gl

[RAVENz46]

Thanks! I realized that I need to add vulkan-loader to library path and now it works!

Do you want to make a PR to update the flake with the new working one?
