cppy build input not available to kiwisolver builder

[l0b0]

Describe the issue

I'm getting the following error when building kiwisolver:

ImportError: cannot import name 'CppyBuildExt' from 'cppy' (/nix/store/278y9crvfd2drswyyp7fpfk7gkrkdawy-python3.9-cppy-1.1.0/lib/python3.9/site-packages/cppy/__init__.py)

The following override does not seem to help:

kiwisolver = super.kiwisolver.overridePythonAttrs (
  old: {
    buildInputs = (old.buildInputs or [ ]) ++ [
      self.cppy
    ];
  }
);

Additional context

Build log from the original project.

I'm trying to build specifically on 21.11, because I've run into different issues using HEAD.

[adisbladis]

This works fine for me on latest nixos-unstable and poetry2nix master.

[adisbladis]

Even when adding a more recent version of cppy as a dev dependency it fails.
I believe it's because cppy relies on the experimental setuptools support for adding project metadata and the setuptools version in 21.11 is too old.

[l0b0]

OK, I'll wait and see if it works itself out. Unfortunately I have a different issue when using latest unstable:

ImportError: /nix/store/9bh3986bpragfjmr32gay8p95k91q4gy-glibc-2.33-47/lib/libc.so.6: version `GLIBC_2.34' not found (required by /nix/store/406z9zpvi19w0y79fn4p3nvpvdyp2425-gdal-2.4.4/lib/libgdal.so.20)

Probably caused by NixOS/nixpkgs#170897.

[SuperSandro2000]

This can probably be closed.
