[Boost-users] Serialization - no & operator for primitives

9 Jun 2005

      I'm using a recent (a few days old) cvs version of boost, and
the serialization libraries, and Visual Studio 7.1 is producing the
error below. This is only happening to classes which I am exporting
(like BOOST_CLASS_EXPORT_GUID(D2::Message,"D2::Message");). The reason I
am exporting them is that they are in many cases a) subclasses of each
other b) accessed through a pointer. Any help would be deeply
appreciated.

My code is:

      template<class Archive >
      static void serialize(Archive & ar, D2::Message& g, const unsigned
int version)
      {
         ar & g.getType(); // an int - error complains about this line.
         ar & g.getSender(); // a string
         ar & g.getMessage(); // a string
      }   

Error message:

c:\D2\API\NewClient\EnhancedMessageHandler.h(132) : error C2679: binary
'&' : no operator found which takes a right-hand operand of type
'uint32' (or there is no acceptable conversion)
