Dear All,
I have encountered a problem I cannot go through
regarding boost::mpi and shared_ptr.
Please consider the following code:
class Foo
{
friend class boost::serialization::access;
template<class Archive>
void serialize(Archive &ar, const unsigned int
version)
{
//...
}
};
//...
mpi::communicator world;
boost::shared_ptr<Foo> pFoo;
if (world.rank() == 0)
pFoo = boost::shared_ptr<Foo>(new Foo);
mpi::broadcast(world, pFoo, 0);
//...
Now unfortunately this doesn't compile, I get the
following error message:
/home/jooam/usr/include/boost-1_35/boost/serialization/shared_ptr.hpp:

boost::shared_ptr<U>&, unsigned int) [with Archive =

Could you tell me please, what I'm doing wrong? I
would appreciate any help.
Have a nice day,
