[Boost-users] [serialisation] XML Archives and BOOST_CLASS_EXPORT_GUID

Hello all, 

This is a corollary to my recent question on serialisation of shred_ptrs
and polymorphic classes - I noted it in that thread but it may be lost
in the debris.

In an effort to get them to work, I have put in a
BOOST_CLASS_EXPORT_GUID in my base and derived classes. However, this
brings up a compilation error...

>>whole load of template faults then... (see below for full error list)

../boost_1_33_1/boost/archive/basic_xml_archive.hpp:66: error :
incomplete type 'boost::STATIC_ASSERTION_FAILURE< false>' used in nested
name specifier
../boost_1_33_1/boost/archive/basic_xml_archive.hpp:66: error : size of
array has non-integral type '<type error>'

Now looking at the code where the final error occurs, it says this is
usually down to an unspecified NVP - i.e. a serialisation of a data item
not in an nvp statements. However, all the classes involved do have this
correctly set up. I have one question on it though..

Should I do this in my derived class to include the base class
serialisation

ar & base_object<A>(*this)

Or should I do this

ar & base_object<A>(make_nvp("base", *this) )

Both give the same compile error

Or is there simply a problem with BOOST_CLASS_EXPORT_GUID that means
that it is emitting something that needs nvp wrapping but this isn't
being done?
