[Boost-users] [serialization] problem with custom archive type

Subject: [Boost-users] [serialization] problem with custom archive type

I have a custom input archive type that has worked fine when statically 
linked to the serialization library.  I'm now must use serialization as 
a DLL and the code no longer compiles.  This is under MSVC9 with 
BOOST_ALL_DYN_LINK defined.  This code works fine on Linux/GCC with 
serialization built as a shared library...so the problem appears 
specific to Windows/MSVC.  Here is a boiled down version of the code 
that exhibits the problem:

// HEADER CONTENTS
#include <boost/archive/xml_iarchive.hpp>

class CustomArchive : public 
boost::archive::xml_iarchive_impl<CustomArchive>
                     , public boost::archive::detail::shared_ptr_helper
{
public:
   CustomArchive( std::istream& is, int foo )
     : boost::archive::xml_iarchive_impl<CustomArchive>( is, 0 )
     , m_foo( foo )
   {

   }

   int GetFoo() const
   {
     return m_foo;
   }

   template<class T>
   void load( T& t )
   {
     boost::archive::xml_iarchive_impl<CustomArchive>::load( t );
   }

private:
   friend class boost::archive::xml_iarchive_impl<CustomArchive>;
   friend class boost::archive::basic_xml_iarchive<CustomArchive>;
   friend class boost::archive::load_access;

   int m_foo;
};

// CPP CONTENTS
#include <CustomArchive.hpp>
#include <boost/archive/impl/basic_xml_iarchive.ipp>
#include <boost/archive/impl/xml_iarchive_impl.ipp>
#include <boost/archive/impl/archive_serializer_map.ipp>

namespace boost
{
namespace archive
{
   template class basic_xml_iarchive<CustomArchive>;
   template class xml_iarchive_impl<CustomArchive>;
   template class detail::archive_serializer_map<CustomArchive>;
}
}

BOOST_SERIALIZATION_REGISTER_ARCHIVE( CustomArchive )

and here are the errors:
