Unable to use leap motion controller with python 3.3.0 (errors generating LeapPython.so)

[jamesbheald]

I'm trying to use the leap motion controller with python3 (as opposed to python 2)

I have followed the instructions for mac (I use macOS Big Sur version 11.6) here: https://support.leapmotion.com/hc/en-us/articles/360004362237

I created a conda environment and installed Python 3.3.0. I also installed swig 2.0.9. I was able to generate LeapPython.cpp (step 3). But when I try to generate LeapPython.so (step 4), I get the following output:
