ocp.nix (help wanted)

[coderofsalvation]

I didn't find ocp in https://search.nixos.org which is fine, because I can just run it via wine.
However, I still tried to come up with a nix-file to build it, but I got stuck on libancient (which is the only lib which is not in the nix-repos).

If you are a nix-developer and you're reading this...then you're very welcome to help out to complete this nix-definition:

It would probably be more clean to add two packages, libancient as a separate package, and then ocp that depends on libancient.

Probably should add alsa-lib as a dependency also.

Here's a flake I made:

thanks! trying it right now

This report probably belongs in a tracker inside NixOS, and NixOS should provide OCP in their repo.

I will close this bug-report in the future, unless there are some comments about why it should not be ;-)
