Motivation for this change

Optional dependency for GNUradio (see #82263 ).

• Built on platform(s)
  • NixOS
  • macOS
  • other Linux distributions
• Tested via one or more NixOS test(s) if existing and applicable for the change (look inside nixos/tests)
• Tested compilation of all pkgs that depend on this change using nix-shell -p nixpkgs-review --run "nixpkgs-review wip"
• Tested execution of all binary files (usually in ./result/bin/)
• Determined the impact on package closure size (by running nix path-info -S before and after)
• Ensured that relevant documentation is up to date
• Fits CONTRIBUTING.md.

From some reason @GrahamcOfBorg had issues with the attempt to split the outputs - hence all the force-pushes. I removed the outputs = []; line, since it's not too bad if all files will be in $out.

Do you intend to use lib/python3.7/site-packages/comedi.py for gnuradio?

I noticed it's not contained in find $(nix-build -E "with import <nixpkgs> {};python3.withPackages (_: [comedilib])" -I nixpkgs=$PWD)/lib/ | grep comedilib, so you might need to move things from $out/${python.sitePackages}/* into a separate folder.

Not really... I just noticed that the build report of it searched for comedilib support and I suspect these is not done via Python but via the c headers.

However, If I do this:

diff --git i/pkgs/top-level/python-packages.nix w/pkgs/top-level/python-packages.nix
index 86339e361cb..efd362b7fc4 100644

+  comedilib = toPythonModule pkgs.comedilib;

   cornice = callPackage ../development/python-modules/cornice { };
 
   cram = callPackage ../development/python-modules/cram { };

This works:

find $(nix-build -E "with import <nixpkgs> {};python3.withPackages (ps: [ps.comedilib])" -I nixpkgs=$PWD)/lib/ | grep comedi

Should I do it?

Should I do it?

Nah, this was mostly a heads-up. I don't really know how comedilib is being used from gnuradio. It should be easy to add if we need it.

Thanks for the PR!
