Hello

This topic is also discussed in the web documentation:

http://www.boost.org/libs/serialization/doc/special.html#export

I am currently struggling with the same issue!

cheers Robbie

Hi Jeshua,

Vaguely related comment on your problem. I was also recently seeing this
"unregistered void cast" runtime error. As far as I could tell it was a
problem relating to my ordering and placement of "#include
<boost/archive/text_oarchive.hpp> (or ditto iarchive), and "#include
<boost/serialization/export.hpp> as well as calls to BOOST_CLASS_EXPORT.

It was nothing to do with my use of void_cast_register, which in fact I
don't use anywhere in any of my code.

So FWIW I think that this error message is not particularly helpful or
well-worded.

Cheers

JP,

Thanks for the comment.

This issue was mentioned to me in my previous message I sent out. I believe I have the includes ordered correctly. What Robert said was that I need to include the archives before the export header file. Here's the order in which I include the serialization headers:

#include <boost/archive/text_oarchive.hpp>
#include <boost/archive/text_iarchive.hpp>
#include <boost/serialization/serialization.hpp>
#include <boost/serialization/base_object.hpp>
#include <boost/serialization/export.hpp>

Here is my code just to make things easier. There should be 5 files:

Thanks,
