Hi Robert,

Indeed the more recent documentation addresses this. http://www.boost.org/doc/libs/1_47_0/libs/serialization/doc/traits.html#export

So I added BOOST_CLASS_EXPORT_KEY2(B, "B") to my b header and BOOST_CLASS_EXPORT_IMPLEMENT(B) to b's cpp file.
I do not get the duplicate symbol anymore, good.

However the serialization now crashes.

My main is simply:

int main()
{
  std::ofstream of("mybin.bin");
  boost::archive::binary_oarchive oa(of);

  A* b = new B();
  oa << b;
   
  return 0;
}

Any idea ?

Thanks,
-V
