Never mind.  Thanks all -- I fixed it myself.  For the archives, in trying to print each level in my hierarchy I had a helper function like this;

template<typename T>
struct printeachlevel
{
    printeachlevel(T& ar) : m_ar(ar) { }
    template<typename X>
    void operator()(X*& level)
    {
        m_ar & boost::serialization::make_nvp(level->m_myNodeName.c_str(), level);
    }
    T& m_ar;
};

The problem was the function operator took a const X*& level -- so when the typename X was class Stock, it turned it into a const Stock*& and that probably made the boost serialization library mad at me.

anyway, teaches me to first look at the compiler error carefully before posting in archives :-)

I hope I don't run into another one the moment I hit send ;-)

Hello all

I am trying to use Boost Serialization library to de-serialize a complex object hierarchy from XML to its class representation.

The class hierarchy gets serialized into XML just fine.  But while trying to do the reverse, that is read from XML and pump it into my class, I run into the following compiler error that is driving me nuts.  Can someone help please?  FYI if its relevant I have a std::list<Stock*> datatype in one of the classes.

The error dump is slightly big so I apologize in advance.  The compiler is VC 7.1 on windows XP.
