Hello,

I'm trying to register a class (named A), because it will be a derived
class. Calling BOOST_CLASS_EXPORT(A) will generate a lot of errors
that look similar. Here is one of them:

/usr/local/include/boost/mpi/datatype.hpp:184: error: no matching
function for call to ‘assertion_failed(mpl_::failed************
boost::mpi::is_mpi_datatype<std::basic_string<char,
std::char_traits<char>, std::allocator<char> > >::************)’

Here is the code:

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
#include <iostream>
#include <boost/mpi.hpp>
#include <boost/archive/text_iarchive.hpp>
#include <boost/archive/text_oarchive.hpp>
#include <boost/mpi/packed_oarchive.hpp>
#include <boost/mpi/packed_iarchive.hpp>
#include <boost/serialization/export.hpp>
#include <boost/serialization/string.hpp>

class A
{
   friend class boost::serialization::access;

   template<class Archive>
   void serialize(Archive & ar, const unsigned int version)
   {
      ar & _text;
   }
};

BOOST_CLASS_EXPORT(A); // I need to export A, because I will use
                       // abstract base pointer. A is not a derived
                       // class for simplicity here.

int main(int argc, char * argv[])
{
   return 0;
}

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

I've found that someone had the same problem  (
http://groups.google.com/group/boost-list/msg/c9a0c133bddd783d ), but
no solution was found.

What am I doing wrong?

Thanks,
