Re: [Boost-users] [mpi] many undefined references toserialize<boost::mpi::detail::mpi_datatype_oarchive>

PLease send me some test code that shows the problem. Are you linking against the Boost.MPI libtrary and to you correctly register your derived types? Matthias On Sep 12, 2012, at 12:30 AM, Brian Budge wrote:

So to Robert's question, I don't think this is something that could be baked into the boost_mpi.so library, since they rely on my own classes. ...

look at .../libs/serialization/src/binary_oarchive.cpp

This file contains the explict instantiations that are added to the library. I would expect that something like this could be made for mpi archives.

I think you're right Robert. I can get my types to serialize fine with the boost::binary_*archive archives, but not with the mpi ones. It's strange because I can get it to work for send, but not recv. I get an exception related to unregistered type.

Indeed if I go and manually serialize every message pointer to a char buffer vis binary_oarchive, and send that via boost mpi, and manually deserialize on the other side from char buffer via binary_iarchive, my program works.

I'm unsure what exactly might need to be instantiated in boost::mpi though.
