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:
Makefile
main.cpp
base.hpp
derived.hpp
derived.cpp

http://www.nabble.com/file/p12487645/serialization_dynamic_test.tar.gz
serialization_dynamic_test.tar.gz 

Thanks,
Jeshua Bratman
