meshlab{,-unstable}: add darwin support by yzx9 · Pull Request #396295 · NixOS/nixpkgs

yzx9 · 2025-04-05T11:11:26Z

This PR adds Darwin support for MeshLab.

I noticed that MeshLab 25.07 has been released — I can upgrade to it after this PR is merged.
LLVM 18 is a workaround for issues with vcglib (vcg: 2023.12 -> 2025.07 #427236) and some other parts of the code. It should work fine in the new version.

I am working on adding Darwin support for meshlab, which is a Qt-based application that includes many plugins. I successfully built it and was able to run the application, but unfortunately, none of the plugins are loading.

Details

The error messages I am encountering are as follows:

I don't see any dynamic dependency errors:

Is there any guidance for debugging or documentation regarding Qt on Nix? Any help would be appreciated!

dwt · 2025-04-13T12:14:28Z

Maybe not something that helps you immediately, but those .so files should probably be .dylib files, as that is the darwin library format. I would start looking where they are built to see why you get .so files (as that usually indicates a linux build).

yzx9 · 2025-04-13T15:22:49Z

@dwt Thanks for your help — it's never too late and always appreciated!
I'm not very familiar with shared library formats, but I noticed that the plugins also use the .so format in the official package. Interestingly, when I try to open the plugins from the official package from nix built meshlab, I get the same error.

dwt · 2025-04-14T05:49:54Z

Strange, they might do something mighty strange upstream to make .so files work? Maybe check with file what these files actually are, just to make sure the didn't just rename .dylib to .so to not have to change some other code?

Rhys-T · 2025-07-30T18:10:28Z

Hmm. They're not actually in Linux ELF .so format - they just have that filename extension for some reason. They're Mach-O files, like they're supposed to be - sorta. If I look at the ones from the official release, they're classified as 'loadable bundles' rather than normal dylibs¹, but that makes sense for plugins. If I look at the ones produced by this derivation, though, they're flagged as being full executables in their own right. They even have main functions!

The difference seems to be that a) you can't link against a bundle, only dynamically load it at runtime; and b) a bundle has a particular program that it expects to be loaded by. ↩

Ah, I see what's happening! All the plugins are incorrectly getting wrapped by wrapQtAppsHook, even though they aren't actually executables!

The hook is looking for anything that has execute permission and is either an ELF or Mach-O file. Libraries have execute permission too, but normally that isn't an issue since the hook looks in $out/bin and not $out/lib… except that it also looks inside the entirety of $out/Applications, and doesn't limit itself to the app's Contents/MacOS subfolder.

Ideally the hook should probably be updated to make sure it's looking at actual executables, or at least limit itself to the MacOS folders of apps. But that's going to be somewhat more involved, and will cause rebuilds for everything using the hook. Best bet for now is probably to set dontWrapQtApps and manually wrapQtApp just the actual program, at least on macOS/Darwin.

@Rhys-T Wow, great job! I gave your solution a quick try, and I can confirm it works perfectly!
I’ll take care of resolving the conflicts and finishing up the remaining tasks later.

@SuperSandro2000 Thanks for your review! I have change all the patchPhase to postPatch, and remove the finalAttrs.pname.

@SuperSandro2000 The build failed due to the sandbox on Darwin. QT applications on Darwin require a sandbox profile, which blocks the sandboxed build. I was able to build the application before, ~~but unfortunately it’s not easy to build again today since the LLVM cache is missing.~~
