Hey - I'm building a Rust application (on a Mac with { system = x86_64-linux } using a linux builder) using crate2nix and on the final executable I'm seeing a dependency to rust-minimal-1.85.0 - which then pulls in a lot of development tooling. Is there any flag etc. I can set to reduce the dependencies?
Sorry I don't have an example I can show - but practically it's not much different than the hello-world example on their repo.
you can try to figure out why with nix why-depends --precise your-store-path unwanted-dependency | 21:37:30 |

Looks like debugging symbols to me (src/header/map.rs etc.)

| utdemir | Hmm - apparently a stdenv.isDarwin check that disables debugging symbols ends up being true even though I thought I passed a nixpkgs with a linux system. That might be it - trying to figure out how to override it now. | 21:44:26 |
 rosssmyth | You can also try using removeReferencesTo | 21:57:18 |

| Pierre Carrier | hi! trying to build a project with crate2nix and I need to set an env var for one of the packages in the workspace. is that possible? | 20:02:36 |
 K900 | I don't think crate2nix is really actively maintained | 20:16:36 |
| Pierre Carrier | @k900 any good alternatives? | 20:23:51 |
 Charles | crane is alright | 20:24:00 |
| Charles | not the same operating principle though | 20:24:07 |
| Pierre Carrier | Rebuilds all deps whenever a single dep changes. | 20:24:14 |
| K900 | Is that really such a problem? | 20:24:35 |
| Pierre Carrier | yeah we actively moved away from it for that reason | 20:24:49 |
| Charles | there's cargo2nix which builds derivations per crate but also looks undermaintained (last commit 3 months ago) | 20:25:13 |
| Charles | * there's cargo2nix which builds derivations per crate too (iirc) but also looks undermaintained (last commit 3 months ago) | 20:26:22 |
| rosssmyth | Should go ask in the Snix channel as they are really the main users of it. | 20:26:25 |
| Pierre Carrier | thanks | 20:26:33 |
| Pierre Carrier | how do I set an env var with crane? :) | 20:42:47 |
| Pierre Carrier | overrideAttrs, apparently :) | 20:46:33 |
| Charles | can't you just do it like you can with mkDerivation? | 21:39:15 |
