Re: [Boost-users] Obscure error while trying to use Boost XML Serialization (boost::archive::xml_iarchive)

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 ;-)
