When building this derivation on aarch64-darwin

{ lib, stdenv, fetchFromGitHub, postgresql, buildPgrxExtension_0_11_3, cargo }:

buildPgrxExtension_0_11_3 rec {
  pname = "pg_jsonschema";
  version = "0.3.1";
  inherit postgresql;

  src = fetchFromGitHub {
    owner = "supabase";
    repo = pname;
    rev = "v${version}";
    hash = "sha256-YdKpOEiDIz60xE7C+EzpYjBcH0HabnDbtZl23CYls6g=";
  };

  nativeBuildInputs = [ cargo ];
  
  CARGO="${cargo}/bin/cargo";


  cargoHash = "sha256-VcS+efMDppofuFW2zNrhhsbC28By3lYekDFquHPta2g=";

 
[...]
}

…I am seeing this error

I am guessing that this might end up being fixed by a combination of the PR’s

llvmPackages_{12,13,14,15,16,17,18,git}.clang: fix libLTO.dylib path

and

cctools: 973.0.1 -> 1010.6

Although I am not 100% sure.

@reckenrode thought I’d ask and see also if there is anything I can do to help with these fixes?

[reckenrode]

If you check the whole log, is there an error about an unrecognized file format? Something about a bunch of hex digits? If so, that’s due to broken LTO support. Looking at upstream’s Cargo.toml, they set LTO = fat on release builds, so I assume that’s it.

I’ve been waiting to move forward due to the freeze on breaking changes before the release. Now that staging is open for post-24.05 changes, I’m going to start cherry-picking prerequisite PRs once the Darwin channel blockers finish building locally.
