Я пытаюсь импортировать расширение Python, написанное на C ++ с Boost.Хотя у меня возникли некоторые проблемы при компиляции расширения с использованием cmake, мне удалось сделать это, связанное с библиотекой boost_python27.Затем я использовал pythons distutils для установки расширения в среду python.
Однако, когда я пытаюсь импортировать модуль, я получаю следующую ошибку:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: dlopen(./tools.so, 2): Library not loaded: @rpath/libboost_python.dylib
Referenced from: /Users/DaniBook/CLionProjects/Uebung1/cmake-build-debug/tools.so
Reason: image not found
Я перепробовал все, что нашел в Интернете, включая переустановку boost и перекомпиляцию с использованием расширений distutils и т. Д., Чтобызаставить его работать.Кто-нибудь может предложить некоторую помощь по этому вопросу, а также ответить, что это зловещее изображение, которое отсутствует?
