Swig errors on python build

[qvs5010]

Describe the bug

Shows errors when running make for pjsua2

Steps to reproduce

pjsua2

cd pjsip-apps/src/swig/python make make install

PJSIP version

2.14.1

Context

when I follow the instructions on page https://docs.pjsip.org/en/latest/pjsua2/building.html#building-python-swig-module

I get swig errors when building, its on a newly installed ubuntu 24.04 both python 3.10 and 3.12 gives the same error.

Log, call stack, etc
