Re: [Boost-users] [MPI] Serializing a class with a string data member

I've added namespace boost { namespace mpi { template<> struct is_mpi_datatypestd::string : public mpl::true_ { }; } } and everything works fine... 2009/7/4 Mathieu Larose :

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 >::************)’

Here is the code:

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - #include <iostream> #include #include #include #include #include #include #include

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, Mathieu Larose
