Re: [Boost-users] [MPI / Serialization] unable to register user-defined class for serialization through base class pointer

Hello,

Note also that if I use dtask pointer instead of task with send and recv, the program runs fine.

Additionaly, if I use primitive type like "int" instead of std::string in my derived class, the compilation goes fine with the export statement.

It seems to me that at some point the compiler tries to get the MPI datatype of std::string even if it shouldn't since it's not a primitive type.

What am I missing here ?

This is strange. Have you tried sending just a std::string or a dtask object? Matthias
