Re: [Boost-users] [mpi] Sending derived classes via MPI and serialize

I'm using a snapshot of 
http://svn.boost.org/trac/boost/browser/branches/release

from 2008-02-20, so almost the latest...

I've done a little more digging and I think it might be related to the 
BOOST_SERIALIZATION_REGISTER_ARCHIVE stuff. Specifically, the errors are 
of the form

include/boost/archive/detail/oserializer.hpp:162: undefined reference to 
`boost::archive::detail::archive_pointer_oserializer<
boost::mpi::detail::ignore_skeleton_oarchive
   <boost::mpi::detail::mpi_datatype_oarchive> 
 >::~archive_pointer_oserializer()'

and I noticed that communicator.hpp only includes forward declarations 
of skeleton archives via

#include <boost/mpi/skeleton_and_content_fwd.hpp>

Perhaps these forward declarations are not sufficient to instantiate the 
  archive pointer serialization code??

Thanks for responding,
Simon
