Thank you, I'm building now!

And just tried it out after compiling, works great on my system!
I had a quick question - we use callPackage
(from nixpkgs) to build our derivations:
https://github.com/djanatyn/ssbm-nix/blob/74c0c466435f9e134e6f4e22e6c5a26d80e7fa53/overlay.nix#L18
This means we specify our input names, and have to change them between nixpkgs revisions: https://github.com/djanatyn/ssbm-nix/blob/74c0c466435f9e134e6f4e22e6c5a26d80e7fa53/slippi/default.nix#L1
We also specify a nixpkgs version (currently nixos-22.05
):
https://github.com/djanatyn/ssbm-nix/blob/74c0c466435f9e134e6f4e22e6c5a26d80e7fa53/flake.nix#L4
A consequence of using callPackage
is that we have to keep our derivation's inputs matching the conventions in our active nixpkgs revision (as I think you encountered, which led to this change!)
I have some open questions about how this interacts with the overlay we export as well.
Anyway, to get to my point: I'd love to bring in these changes. Do you think we should also update inputs.nixpkgs.url
to be nixos-unstable
?
I think that might be the best "supported" version of nixpkgs to pull in, and it would be nice to say in the README, "we explicitly support nixos-unstable
, but you can use other revisions like this..."
I'd also like to update our flake.lock
, which is currently pointing to a very old nixpkgs revision from 2020:

Thanks again for these changes, I'm approving them. No worries if you don't have any thoughts on these issues, just wanted to ask!
And once again, thanks for the contribution :)
Do you think we should also update inputs.nixpkgs.url to be nixos-unstable?
I personally would choose nixos-unstable or nixpkgs-unstable over nixos-22.05.
I am not sure about callPackage
.
This compiles :)
