Looking for some help in order to finish [WIP] ZLUDA: init at 3 by errnoh · Pull Request #288644 · NixOS/nixpkgs · GitHub
This packages GitHub - vosen/ZLUDA: CUDA on AMD GPUs, which is rather complex library for running CUDA applications with AMD hardware.
Before starting the PR I did manage to build the package manually (resulting in the lockfile that’s being used in the PR), but any attempt to compile it in a package just results in errors. I’ve made some progress on the package (thanks @SergeK), but there’s the nagging feel that if I could get someone familiar with Rust to take a look this would be done quite fast 
Details are in the PR, but basically the furthest I’ve got so far is:

For full logs, run 'nix log /nix/store/1almnpy0bpkmsa1gm3c0g2hxg3fvpivf-zluda-3.drv'.
which seems to fail the following build.rs:
use vergen::{Config, vergen};
fn main() {
vergen(Config::default()).unwrap()
}
