[Boost-users] Re: Serialization and shared_ptr

Sorry this isn't clear from the documentation.  At the end of the file
shared_ptr.hpp
you'll find special macros to handle this:

#define BOOST_SHARED_POINTER_EXPORT_GUID(T, K)  ...

#define BOOST_SHARED_POINTER_EXPORT(T)  ..

Using these should do the job for you.
