Re: Issues compiling pjsip and pysua on centos 7

[Luke Biddle <lukeandrewbiddle@xxxxxxxxx>]

That ticket is for the python wrapper for PJSUA2, however this part of the build is for PJSUA which is still in python2.

In the build error you posted we can see:
Leaving directory `/root/pjproject-2.7.1/pjsip-apps/src/python' -I/usr/include/python2.7 -c _pjsua.c -o build/temp.linux-x86_64-2.7/_pjsua.o

which confirms that the pjsua, which lives in pjsip-apps/src/python, was being built using python2.7.

If you did intend to use PJSUA2 for it's python3 support, you may run into the issue I mentioned here: http://lists.pjsip.org/pipermail/pjsip_lists.pjsip.org/2017-November/020351.html

Unfortunately I never found a way past it, but keep me posted if you have more luck!

Luke,

Sorry I do not understand. I thought build defaults to python 3 now.

Looks like the build is trying to use python2.7, make sure you have the headers for that version too.

Thank you for lightening fast response Ernesto. I figured it was something stupid. Still doesn't work yet.

The issues is obvious, your python headers are missing. You'll need to
install either python-devel or python34-devel depending on the python
version you wish to use.
