I am seeing a peculiar issue: nix build works just fine but when using the flake from my NixOS config I get complaints about Rust version:

07:20:15
@curid:matrix.orgCuridwhich rust version does your nixos config use?07:31:36
@simon.brandner:envs.netŠimon BrandnerCurrently none - I made sure I have no rustup, rustc or cargo installed and I am still seeing this...07:50:02
@simon.brandner:envs.netŠimon BrandnerBut seems awfully like the oblichey flake is pulling nixpkgs from my system instead of its own...07:51:09
@curid:matrix.orgCuridyou obviously can't use rust programs without a rust compiler07:51:37
@simon.brandner:envs.netŠimon Brandner Well I am using pkgs.rustPlatform.buildRustPackage to build the oblichey flake 07:52:57
@simon.brandner:envs.netŠimon BrandnerWhich as far as I understand it should get the correct Rust version and compile in a sandboxed env07:53:29
@simon.brandner:envs.netŠimon Brandner The same way it does this when doing nix build 07:53:40
@blitz:chat.x86.lolblitz
In reply to @simon.brandner:envs.net
But seems awfully like the oblichey flake is pulling nixpkgs from my system instead of its own...
Did you use a 'input.nixpkgs.follows' when pulling in the flake? 		08:04:20
@simon.brandner:envs.netŠimon Brandner Nope, it's a simple: oblichey.url = "git+file:///home/simon/GIT/Rust/oblichey"; 08:04:46
@simon.brandner:envs.netŠimon BrandnerI wonder if this is somehow related to a bug I had some time ago: https://github.com/rafaelrc7/wayland-pipewire-idle-inhibit/issues/708:05:01
@blitz:chat.x86.lolblitzCan you post a complete failing example? 08:06:51

08:19:17
@blitz:chat.x86.lolblitzIn module.nix you do pkgs.callPackage to build your program. This pkgs is the one where you use the module. I assume this is where your problem comes from 08:20:30
@blitz:chat.x86.lolblitzThe quick fix would be in your NixOS config to manually set the package option of this module to the package output of the flake 08:21:31
@blitz:chat.x86.lolblitzThis is a pretty common issue with flakes and modules. 08:21:56
@samasaur:matrix.orgsamasaur I think the real fix is running nix flake lock --update-input nixpkgs in your nixos config 08:22:10
@blitz:chat.x86.lolblitzBut it 'works as designed'08:22:11
@blitz:chat.x86.lolblitzOr that :)08:22:19
@simon.brandner:envs.netŠimon Brandner Not sure I follow - I would think this would be the pkgs specified in the flake.lock of the app's flake... 08:23:04
@simon.brandner:envs.netŠimon Brandner
In reply to @samasaur:matrix.org
I think the real fix is running nix flake lock --update-input nixpkgs in your nixos config
(I am blocked by a few things 😅) 		08:23:24
@samasaur:matrix.orgsamasaurhonestly I would have thought so too but the error you’re getting seems to be an issue with nixpkgs being out of date08:23:56
@samasaur:matrix.orgsamasaurand given that building standalone is working I am assuming the issue is with your nixos config flake08:24:16
