Bisect has identified https://github.com/NixOS/nixpkgs/pull/238978 (specifically 0fe7fee623de691acff1db0178de01e39a22319d) as the source of this failure in nixpkgs, cc @fpletz. See also upstream issue https://github.com/AcademySoftwareFoundation/OpenColorIO/issues/1800.

If you're using a flake, this is how I was able to mitigate this until it's fixed.

I rolled back the changes from #238978 in a branch on my fork, and used it as an overlay for the affected packages like this:

  inputs = {
    ...
    nixpkgs-colorio-fix.url =
      "github:cafkafk/nixpkgs/cafkafkdev-colorio-downgrade";
    ...
  };

This is how you would add them to your overlay:

overlay = final: prev: {
  ...
  inherit (nixpkgs-colorio-fix.legacyPackages.${prev.system})
    zlib-ng minizip-ng;
  ...
}

Ofc, depending on how you do stuff, you'll have to fiddle with it a bit to get it to work.

The fix is now on the nixos-unstable branch, but I still cannot build my system after updating, with the same build failure for opencolorio. Is this expected?

[wegank]

Probably not, since opencolorio and blender both build on Hydra.

Oh thank you, this is very bizarre. I will ask on the forum what's going on
