[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?

Thanks Guys - that fixed the compile issue. Been staring at the documentation for a day, and still managed to miss that one - even more annoying when it was exactly what I was expecting to look for. I have to say I do find the documentation for serialisation a little disjointed at times - it's all there, just difficult to find unless you know where to look (which rather negates the reason for the documentation!!) Even better news, adding the GUID stuff has fixed the other issue I have been seeing - and now I can serialise away to my hearts content. James
