"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.

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

Thanks Pavlo, that's what I have done. Bit of a pain when you have a header only class though... James
