Не удалось связать с библиотекой C++ в проекте iOS

Question

Я пытаюсь установить связь с libupnpx, следуя инструкциям, но я не могу ссылаться на стандартную библиотеку C++.

Other linker flags устанавливается -lstdc++ -all_load (как вы можете видеть here), однако, не может найти C++ функции: here.

Любая идея, что мне может не хватать?

Спасибо.

EDIT: Как спросил @Speeder, вот полные журналы:

Answer 1

Я знаю, что это не совсем ответ, но я в конечном итоге использовала Cocoapods импортировать библиотеку. Не могу поверить, что я еще не проверил, что это было раньше!
