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?
