RQT (ROS2 Humble) fails to build on MacOS (arm64)

[hegde-atri]

Adding rqt to my package list, it fails to build.

First there is an error about shiboken2 being marked as broken.
error: Package ‘shiboken2-5.15.11’ in /nix/store/snp5f95xhkz89kdw9703kana3m6xfd0a-source/pkgs/development/python-modules/shiboken2/default.nix:54 is marked as broken, refusing to evaluate.

After overriding this, tango-icon-theme fails to build is it is not available on requested platform.

After also overriding this, I get a build error with gnome-icon-theme.

error: builder for '/nix/store/irz9n8mhrcdkbg5g3qb1jb0xmb424hfg-gnome-icon-theme-3.12.0.drv' failed with exit code 1;

Where do I begin to resolve this?

@hegde-atri please check the pull request.

Most of the issues have been fixed in the upstream code, but they haven’t been made available to humble or this overlay yet. To fix the issues by yourself, download the package (the link is in, for example, tango-icons-vendor/default.nix. You might need to set up a shell with the dependencies (buildInputs) of this package and compile it. In this case, it’s failing. But if you look into tango-icons-vendor's CMakeLists.txt, it actually installs the needed icons for Apple and MS platforms (you can download the source of tango-icon-theme and find out they're mostly the same), so we can skip that dependency.
