### Description

I tried package app_python3 and found this error on all dist where python3 is exist ``` [ 419s] CC (gcc) [M app_python.so] python_support.o [ 419s] python_support.c:22:20: fatal error: Python.h: No such file or directory [ 419s] #include <Python.h> [ 419s] ^ [ 419s] compilation terminated. [ 419s] make[2]: *** [python_support.o] Error 1 [ 419s] make[1]: *** [modules] Error 1 [ 419s] make[1]: Leaving directory `/home/abuild/rpmbuild/BUILD/kamailio-5.3.0-dev5/src' [ 419s] make: *** [every-module] Error 2 ``` But `Python.h` is present in system. Include dir and libsdir you can get using command `python3-config`. Like ``` # python3-config --includes -I/usr/include/python3.7m -I/usr/include/python3.7m # python3-config --libs -lpython3.7m -lpthread -ldl -lutil -lm ``` ### Possible Solutions

Update make files to use `python3-config`.
