On the sending side, I have BOOST_CLASS_EXPORT_KEY( namespace::namespace::myclass )

I don't know why it is not sent down the pipe.

Note that you'll have to have BOOST_CLASS_EXPORT... on BOTH sides.

This is usually assured by having the save and load symetrical.

Thanks, I do.

So there's nothing particular about using BOOST_CLASS_EXPORT_KEY

instantiation of a class template?

I think what's left is to find where the class name is written for

packed archive, which is what I'm looking for.

I found the cuplrit and will submit a patch when I find time -

with a the mpi o probably tomorrow night or over the weekend.

has this been fixed yet?

Matthias asked me to test the mpi archives. I need to get time to look at the issue again. Do you observe the same problem?

yes class name not found. but i think I got it working but include correct headers before BOOST_CLASS_EXPORT macro. the macro didnt register the class until this. but i dont know what headers it requires i just included lot of the serialization headers
