Steps to reproduce

nix-shell shellR.nix -I nixpkgs=https://github.com/nixos/nixpkgs-channels/archive/nixos-unstable-small.tar.gz

ld: library not found for -liconv

I am not getting the iconv issue on master.

Thank you for your contributions.

This has been automatically marked as stale because it has had no activity for 180 days.

If this is still important to you, we ask that you leave a comment below. Your comment can be as simple as "still important to me". This lets people see that at least one person still cares about this. Someone will have to do this at most twice a year if there is no other activity.

Here are suggestions that might help resolve this more quickly:

1. Search for maintainers and people that previously touched the related code and @ mention them in a comment.
2. Ask on the NixOS Discourse.
3. Ask on the #nixos channel on irc.freenode.net.

Tentatively closing this since bauer said he didn't see it on master, and there hasn't been any more activity.

Feel free to squeak if this is still a problem--I'll happily reopen it.

I've been getting this using master for the past week or so and always failing on compiling procs v0.11.4 with rust. What's funny is I have the exact same Nix setup on my work computer (Macbook Pro from 2018 with latest macOS), but the error is on my personal Macbook Pro from 2013 running Catalina 10.15.7.

This exact error seems to be happening with any rust-based nix package.

@rpearce I'm not specifically familiar, but I get the impression from reading other issues that missing libiconv is a common/general macOS package issue. How recently did you pull master? It looks like your specific case might be fixed in #117559.

If there's a persistent difference between the two systems at the same nixpkgs commit, it's probably worth a new issue. (There may also be a new issue in master--it is fairly common :)

[rpearce]

@abathur That looks like it'll definitely fix it. ~I pull master almost daily~ (this wasn't true; I pull nixos-unstable almost daily), and I didn't have the time to look into it for a week or so. Thanks for that link! I'll leave this thread alone
