I've got a class hierarchy that can already be serialized into text or
binary archives.  I'm explicitly instantiating the template functions
for serialize and/or load/save.
I'm trying to add the capability to have boost mpi perform the
serialization through send/recv/broadcast.
If your class has serialization support, that's enough.  You should
not provide specialization for mpi::detail classes.
(Of course, YMMV - since you didn't provide any code, my comment above
could be completely off ...)

Thanks for the replies.  Here are the macros I made to perform the
explicit instantiation:

#define INSTANTIATE_FUNCTION_FOR_INPUT_ARCHIVES(FUNC)                      \
template void FUNC(boost::archive::binary_iarchive &archive,               \
                   const unsigned int version);                            \
template void FUNC(boost::mpi::packed_iarchive &archive,                   \
                   const unsigned int version);                            \
template void FUNC(boost::archive::text_iarchive &archive,                 \
                   const unsigned int version)

#define INSTANTIATE_FUNCTION_FOR_OUTPUT_ARCHIVES(FUNC)                     \
template void FUNC(boost::archive::binary_oarchive &archive,               \
                   const unsigned int version);                            \
template void FUNC(boost::mpi::packed_oarchive &archive,                   \
                   const unsigned int version);                            \
template void FUNC(boost::mpi::detail::mpi_datatype_oarchive &archive,     \
                   const unsigned int version);                            \
template void FUNC(boost::archive::text_oarchive &archive,                 \
                   const unsigned int version)

#define MAKE_SERIALIZE_FUNCTIONS(CLASS)                                    \
INSTANTIATE_FUNCTION_FOR_INPUT_ARCHIVES(CLASS::serialize);                 \
INSTANTIATE_FUNCTION_FOR_OUTPUT_ARCHIVES(CLASS::serialize)

Then, along with implementing the templatized versions of serialize
for each class, I will call the MAKE_SERIALIZE_FUNCTIONS(myclass) in
each myclass.cpp.

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.  I was just surprised to find that I needed to explicitly
instantiate with something from detail rather than just the packed
archives.

Thanks,
  Brian
