im trying to create a SIP client using Raspberry pi 2, i want to do it using pjsua2 library for python. i downloaded the git file for pjsip project, ran ./configure, then i ran make dep && make && make install in pjsip directory successfully. afterwards as mentioned in: https://docs.pjsip.org/en/latest/pjsua2/building.html#building-python-swig-module
i tried running make command in ./pjsip-apps/src/swig/python but every time i try to do so, the entire system freezes, any idea what should i do?

the last message it gives in terminal is:

python3 setup.py build
UserWarning: normalizing '2.14-dev' to '2.14-dev0'
warnings.warn(tmpl.format(**locals()))
