Как можно использовать boost :: serialization с std :: shared_ptr из C ++ 11?

Это результат прокрутки собственного на основе заголовка общего указателя повышения, например, на основании <boost/serialization/shared_ptr.hpp>.

Просто скопируйте & amp; Вставьте ниже в заголовочный файл и включите его:

Вы можете увидеть различия с <boost/serialization/shared_ptr.hpp> здесь

В основном,

• переименовано включает охранник
• изменено boost::shared_ptr на std::shared_ptr
• включено <memory> вместо <boost/shared_ptr.hpp>
• защищено null_deleter от переопределения в случае, если вы также использовать boost::shared_ptr
• удалено BOOST_SERIALIZATION_SHARED_PTR_132_HPP - что бы это ни значило?

Пока что, кажется, это работает просто отлично.
