[mpi] Sending derived classes via MPI and serialize
I'm trying to send polymorphic objects using boost::mpi, but I'm getting
extensive "undefined reference" errors for the simple test case below.
If I #include

Do you use the latest version from svn or an older version? Matthias
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

Can you try to add BOOST_SERIALIZATION_REGISTER_ARCHIVE (boost::mpi::detail::ignore_skeleton_oarchive) in line 69 of boost/mpi/detail/ignore_skeleton_oarchive.hpp Matthias On 6 Mar 2008, at 10:40, Number Cruncher wrote:

Perhaps these forward declarations are not sufficient to instantiate the archive pointer serialization code??
Thanks for responding, Simon

This doesn't compile because ignore_skeleton_oarchive is a template
class not a specific type. There is a similar macro in
mpi_datatype_oarchive.hpp with an mpi_datatype_oarchive specialization:
BOOST_SERIALIZATION_REGISTER_ARCHIVE(
boost::mpi::detail::ignore_skeleton_oarchive
boost::mpi::detail::mpi_datatype_oarchive)
but with all the forward declaration includes, I can't actually work out
which classes have been fully defined when this indirectly invoked via
the #include "communicator.hpp".
I'm guessing the instantiation is not actually built because at the
point of BOOST_SERIALIZATION_REGISTER_ARCHIVE,
ignore_skeleton_oarchive
Sorry, that was nonsense ... forget it please can you please check whether line 45 of mpi_datatype_oarchive.hpp contains BOOST_SERIALIZATION_REGISTER_ARCHIVE (boost ::mpi ::detail ::ignore_skeleton_oarchiveboost::mpi::detail::mpi_datatype_oarchive) and can you then please check whether serializing and deserializing work if you use a text archive instead of MPI?
