Build failure: libdevil (affects ffmpeg-full) #309417

Closed peterldowns closed 6 months ago

peterldowns commented 6 months ago

Steps To Reproduce

On MacOS Sonoma 14.4.1 on an M1 Macbook Pro, with nixpkgs pinned at ee4a6e0f566fe5ec79968c57a9c2c3c25f2cf41d, building ffmpeg-full fails when compiling libdevil-1.7.8:

nix build github:NixOS/nixpkgs/ee4a6e0f566fe5ec79968c57a9c2c3c25f2cf41d#ffmpeg-full

Build log

Full log available at this gist, but here's an excerpt of the failures from the nix build command:

Additional context

I pin nixpkgs in the flake user registry, and reference it in my darwin configuration. Previously I had it pinned to 807c549feabce7eddbf259dbdcec9e0600a0660d, and on this same computer, building against that commit still works

I didn't do a full bisect, but I also can verify that the following pinned commit also works:

Technically not a build failure of ffmpeg but we should get libdevil out of the closure if it's broken.

Atemu commented 6 months ago

The offending package should be a rather easy workaround via -Wno-register but I currently do not have access to a mac.

Apologies for mislabeling the report, and thank you for (a) correcting it, (b) the quick response.

The offending package should be a rather easy workaround via -Wno-register but I currently do not have access to a mac.

If you give me a command to run, I can help by running it and telling you if it works!

Atemu commented 6 months ago

Setting env.NIX_CFLAGS_COMPILE="-Wno-register"; in the mkDerivation call of the package should do it.

peterldowns commented 6 months ago

@Atemu sorry, I'm not that experienced with Nix, can you share a snippet of code doing it? Do I need to do it for ffmpeg-full, or just for libdevil? Do I do this in my flake that says to install ffmpeg-full somehow?

If it's easier to just fix it yourself without me, feel free to ignore. Thanks again for the quick response by merging #309423 🙏

peterldowns commented 6 months ago

OK, seems to work with this overlay on pkgs:

      environment.systemPackages = with pkgs.extend(self: super: {
        libdevil = super.libdevil.overrideAttrs (oldAttrs: {
          NIX_CFLAGS_COMPILE = "-Wno-register";
        });
      }); [ 
        # ...
        ffmpeg-full
        # ...
        ];
