Python 3.11 NOT INSTALLING / BUILDING

[jakobbaumgartner]

It would appear that Python Robotics Toolbox version 1.10 does not work when installing on Python >= 3.11. I have tried installing it on windows 11 - Python 3.11.3 as well as on ubuntu 24.04 (WSL2) - Python 3.12.3, using github repo and pip.

I was able to built version 1.10 on Ubuntu 22.04, which uses Python 3.10.12.

  note: This error originates from a subprocess, and is likely not a problem with pip.

I was able to solve this by downloading qhull from this link: http://www.qhull.org/download/qhull-2020-src-8.0.2.tgz and extracting it to the build folder (as suggested in the error message).

I was not successfull in this, however when using Ubuntu 22.04, which has older Python version installed, the toolbox works. Do wish they updated it.
