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

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_oarchive<boost::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?
