The library already has serialization implemented for 
boost::int64_t

which would be more portable.  Maybe you want to try this.

  The code as posted looks solid to me.

  This might be trivial, but

  Checked that the code is actually included in the place where the serialization is instatiated ?

  Have you tried replacing your typedefs with __int64 ? (thus removing the typedefs)

  Or maybe use the STRONG_TYPEDEF macro that comes with serialization lib (undocumented i think).

    Thanks Steve, I tried that but I'm still getting no joy ...

    Could it be that unsigned __int64 is not a class, but an integral data type?

    I have two typedefs of unsigned __int64 type: TimeCode and FileSize. I'm assuming the compiler is smart enough to infer the difference.

    I've changed my source according to the docs:

    namespace boost
    {
      namespace serialization
      {

          template<class Archive>

          void save(Archive & ar, const unsigned __int64& big, unsigned int version)

          {
              ar & sizeof(big);
              ar.save_binary(&big, sizeof(big));
          }

          template<class Archive>
          void load(Archive & ar, unsigned __int64& big, unsigned int version)

          {
              size_t size = sizeof(big);
              ar.load_binary(&big, size);
          }

      }

    };

    BOOST_SERIALIZATION_SPLIT_FREE(unsigned __int64)

    And it still complains with
