Python 3.12

[arminbahl]

Hi,

Your package is of tremendous help for us to use Python to link to our Spinnaker SDK-based FLIR Cameras. With Python 3.12 around the corner, do think it would be possible to provide a Python 3.12-compatible pip wheel? This would allow us to upgrade our systems to the latest Python version and be happy for a few years.

Thanks and best! AB

I have tried to compile from source code. Include path, and lib configuration are fine. But I am getting various compiling errors:

  !!

          ********************************************************************************
          An error happened while installing `rotpy` in editable mode.

          The following steps are recommended to help debug this problem:

          - Try to install the project normally, without using the editable mode.
            Does the error still persist?
            (If it does, try fixing the problem before attempting the editable mode).
          - If you are using binary extensions, make sure you have all OS-level
            dependencies installed (e.g. compilers, toolchains, binary libraries, ...).
          - Try the latest version of setuptools (maybe the error was already fixed).
          - If you (or your project dependencies) are using any setuptools extension
            or customization, make sure they support the editable mode.

          After following the steps above, if the problem still persists and
          you think this is related to how setuptools handles editable installations,
          please submit a reproducible example
          (see https://stackoverflow.com/help/minimal-reproducible-example) to:

              https://github.com/pypa/setuptools/issues

          See https://setuptools.pypa.io/en/latest/userguide/development_mode.html for details.

note: This error originates from a subprocess, and is likely not a problem with pip. ERROR: Failed building editable for rotpy Failed to build rotpy ERROR: Could not build wheels for rotpy, which is required to install pyproject.toml-based projects`

Is this a problem with Cython? Would it be possible to provide a new compiled wheel against Python 3.12.

Thanks!
