Steps To Reproduce

Steps to reproduce the behavior:

  1. build rustc with LLVM stdenv. 
    let
nixpkgs = builtins.getFlake "github:NixOS/nixpkgs/nixos-unstable";
pkgs = import nixpkgs {
localSystem = "x86_64-linux";
crossSystem = {
  system = "x86_64-linux";
  useLLVM = true;
  linker = "lld";
};
};
in pkgs.pkgsBuildHost.rustc

The issue is that rust is unconditionally trying to link libgcc_s, but under pkgsLLVM there are no gcc builtins.

The relevant error is:

It looks like this also shows up trying to build static musl binaries, see: https://github.com/rust-lang/rust/issues/82521

And alpine appears to have a patch to work around this: https://github.com/rust-lang/rust/issues/55120

So maybe nixpkgs needs to patch the linking of libgcc_s out of the rust toolchain under stdenv.targetPlatform.useLLVM.

Reading the LSB, https://refspecs.linuxbase.org/LSB_4.1.0/LSB-Core-generic/LSB-Core-generic/libgcc-s.html the interfaces provided by libgcc_s are those relating to unwinding, which on pkgsLLVM is provided by llvm-project/libunwind.

Just curious, what's the difference between libgcc and libgcc_s? liburing has this same issue but with libgcc, I'm wondering if the solution applied upstream for #320177 could be applied here (upstream PR: https://github.com/axboe/liburing/pull/1016).

My current impression is that rust itself is inserting a -lgcc_s because it thinks it is needed here.

Yeah, you're right. It looks like the source of the problem is there.

RossComputerGuy commented 1 month ago

Looks like enabling llvm-libunwind will fix it.

RossComputerGuy commented 1 month ago

Looks like enabling llvm-libunwind to either in-tree or system still results in this:
