There is a rust package that added the following flag: "-Clink-arg=-fuse-ld=lld".
At first, the nix build was failing because it couldn't find ld. I added lld to nativeBuildInputs and the built went fine.
However, the patching is not working anymore. When I run ldd on the final binary, it has several "not found" libraries.
Any idea what I should do ?

When I use buildRustPackage in a workspace it tries to build all the dependencies in the workspace instead of just the binary I want build. Is there a way to avoid this?

yeah I tried the cargoBuildFlags option and that doesn't seem to work.

This is the project I'm doing it on. The workspace recently got updated to have some wasm stuff and this package: https://github.com/kixelated/moq-rs/blob/main/nix/packages/moq.nix#L10 is trying to build the WASM stuff even though it doesn't depend on it

cargo build -j 24 --target x86_64-unknown-linux-gnu --offline --profile release --package moq-relay

If I run this exact cargo command that nix build is using then it builds fine

Hi Toma ,
Could you please review this again?
https://github.com/NixOS/nixpkgs/pull/282798

What do you think is missing to move forward? Unit tests?
