"The macro BOOST_CLASS_EXPORT_GUID associates a string literal with a class. In the above example we've used a string rendering of the class name. If a object of such an "exported" class is serialized through a pointer and is otherwise unregistered, the "export" string is included in the archive. When the archive is later read, the string literal is used to find the class which should be created by the serialization library. ****This permits each class to be in a separate header file along with its string identifier****. There is no need to maintain a .... Is the document misleading here, or have I missed something??
It says that the class declaration may be placed in a separate header, but that doesn't mean BOOST_CLASS_EXPORT_GUID must be placed to that header too :) When you create a separate header for the class, usually you also create a separate .cpp for it. Place BOOST_CLASS_EXPORT there and everything will work fine. WBR, Pavlo Korzhyk ICQ#155870780
