Я реализовал контроллер MP C в диспетчере трафика CARLA 0.9.8. Этот контроллер MP C зависит от IPOPT.
Команды Carla make (make rebuild; make PythonAPI) работают нормально.
Однако import carla в скрипте python spawn_npc.py выдает следующую ошибку:
ImportError: /home/DNDE.EMEA.DENSO/cha/.cache/Python-Eggs/carla-0.9.8-py2.7-linux-x86_64.egg-tmp/carla/libcarla.so: undefined symbol: _ZN5Ipopt16IpoptApplicationC1Ebb
После нескольких часов поиска в Google я предполагаю, что мне нужно изменить файл setup.py, чтобы включить и связать библиотеку ipopt, которая находится в /usr/local/lib.
Но моя процедура проб и ошибок не была успешной
