я скомпилировал pjsip 2.8, используя эту настройку

 ./configure CXXFLAGS="-O3 -DNDEBUG" --prefix=/usr/pjproject-2.8
make dep amp; make
make install
  

я тестирую simpleua.c в CLion 2018.3.4, он может работать, но не может отлаживать исходный код статической библиотеки pjsip, я новичок в gcc, незнаком с отладкой внешней статической библиотеки.
