 slby | This is the problem that crate2nix gives me:
Caused by:
feature `edition2021` is required
consider adding `cargo-features = ["edition2021"]` to the manifest
crate2nix failed.
Does anyone know where I should specify the manifest? I am using generatedCargoNix

I needed to use the unstable channel, then it worked. | 20:17:38 |

Hi, I'm trying to use naersk to build a rust project, but it seems like both the main-deps derivation and the main derivation are compiling all the dependencies of the project, would anyone be able to help me debug this? | 18:34:02 |

| 18:52:27 |
| Nick Hu | Before main begins its build phase, naersk has successfully untarred a bunch of stuff into ./target/release/..., and I also confirmed manually that the output tarball of the main-deps derivation is not empty (it's > 100MB) | 18:53:30 |
| Nick Hu | But for some reason whenever it starts building it wants to recompile everything | 18:53:47 |

| wiredhikari | Hello I am a bit new to nix packaging for rust apps, could anyone share some resources apart from https://nixos.org/manual/nixpkgs/stable/#rust | 06:22:25 |

Hello I am a bit new to nix packaging for rust apps, could anyone share some resources apart from https://nixos.org/manual/nixpkgs/stable/#rust https://github.com/kolloch/crate2nix https://github.com/yusdacra/nix-cargo-integration/ https://github.com/nix-community/naersk https://github.com/nix-community/fenix https://github.com/oxalica/rust-overlay https://www.tomhoule.com/2021/building-rust-wasm-with-nix-flakes/ https://hoverbear.org/blog/rust-bindgen-in-nix/ https://nixos.wiki/wiki/Rust | 09:00:49 |
 tomberek | @slby: while still experimental and a bit in flux, https://github.com/nix-community/dream2nix#test-the-experimental-version-of-dream2nix has been an quick/easy way to get rust apps packaged when needed, not ideal for Nixpkgs yet. | 13:14:53 |
| Nick Hu | +1 for yusdacra/nix-cargo-integration, it's really a nice framework. Although I would suggest using the version with crate2nix support, as dream2nix is not stable enough in my experience | 16:03:13 |

@slby: while still experimental and a bit in flux, https://github.com/nix-community/dream2nix#test-the-experimental-version-of-dream2nix has been an quick/easy way to get rust apps packaged when needed, not ideal for Nixpkgs yet. Do you know how to get the .justBuild of dream2nix working in the presentation? I like the possibility of makeFlakeOutputs, but when integrating into an already existing system, I find it a little werid. | 06:31:51 |
| slby | But yes, dream2nix is pretty amazing. | 06:32:07 |
| tomberek | For more complex usage or integration with a larger system it might be easier for the moment to try buildRustPackage | 07:18:01 |
| slby | Yes, but then caching doesn't work as well anymore, at leas that's what I have found. They have all their place atm.

 [0x4A6F] | RPATH, or why lld doesn’t work on NixOS | 17:11:48 |

RPATH, or why lld doesn’t work on NixOS https://discourse.nixos.org/t/how-rpath-works-or-doesnt-on-nixos/18182 | 17:14:47 |
 hexa | lld is actually llvmPackages.lld | 17:18:48 |
| hexa | so llvmPackages.binutils gets you a wrapped version of lld, but llvmPackages.lld doesn't | 17:19:08 |
| hexa | I hope there is a good reason for that behaviour 🙂 | 17:19:17 |
| slby | Is there a good way to expose features in flakes?
| 20:13:47 |
| slby | So when I do a nix run / nix build I can pass a flag? Or do I need to create a different package just for that. | 20:14:25 |
 cole-h | Flakes are pure, so you can't use --arg asdf with them
You'd have to have a different package per configuration | 20:25:51 |
| slby | Thanks, that confirming my assumption, wow that can get a lot of packages quickly.
