Order of link flags for rust seems significant now

[Fuuzetsu]

Describe the bug

Rust 1.61 and rust builder in nixpkgs don't play nicely together anymore.

See first point of https://github.com/rust-lang/rust/blob/fe5b13d681f25ee6474be29d748c65adcd91f69e/RELEASES.md#compatibility-notes, linking to rust-lang/rust#93901

Steps To Reproduce

I don't have a small/public repro on hand right now. If someone has one, please contribute. If not, I can try to come up with one on Monday. Might be easy to get one out of rust issue tracker as they seem to be getting flooded with linker tickets today due to the change.

Expected behavior

Programs build and link but instead we get linker errors.

nixpkgs 55fad6c081850b3e1d93f87a72c14a383a8e1e9d, rest not that relevant? I'm using oxalica's rust-overlay to get Rust 1.61.

[Fuuzetsu]

I updated to Rust 1.62 and recent nixpkgs and issue seems to be gone somehow. Maybe by luck or maybe rust-lang/rust#96436 had something to do with it?

[duxovni]

Was this fixed by #177436 ? That seemed to solve all of my nix rust building issues.

@duxovni aha, yes, I think this is exactly it. I was surprised to find that -l flags were missing from the output when trying with recent nixpkgs and Rust 1.62 because their wrong order was the cause of an error to start with. I will close the ticket, thank you for the link.
