      Just a guess, but are the EXPORT macros being used in side a namespace?
They should be outside of any namespace.

In addition I resurrected this post to the newsgroup.  It
is  exactly the same problem I am having:
boost 1.32, with VC7.1 I'm getting compiler errors in two
unrelated translation units both dealing with
std::setstd::string data members. I've gone through and
ensured that i've #include'd the  and 
headers from boost/serialization. Any ideas on what might
be causing this problem? This has worked fine previously
with boost 1.31 and serialization20 version of the library.
Why would the 3 argument overload not be found?
Below are the (beginnings of the ) related compiler errors.
Thanks, Jeff

Robert,
Thank you.  My project requires both linux and Win32
support.  When I use this macro in win32 environment I
get
a compile time error.  It generates a fairly long error
which I can send you but here is the first few lines
which
are possibly the most important.
Again it is fully compiling/linking/running in Linux.

When I #ifdef the BOOST_CLASS_EXPORT(ClassName) macros I
compile/link/and run.  Of course base class serialzation
is
disable for Win32 at the moment because of this.
Thanks for any help,

This is addressed with the alternative
BOOST_CLASS_EXPORT
method.  its
described in the serialization documentation.

Hi all,
I have a container class that has a vector which
contains
several other classes.   My container class has a
serialize
function that looks like this:
friend class boost::serialization::access;
template<class Archive> void serialize (Archive &ar,
const
unsigned int version)
{
   // save/load base class information
   ar &
BOOST_SERIALIZATION_BASE_OBJECT_NVP(MyBaseClass);
   ar.register_type(static_cast(NULL));
   ar.register_type(static_cast(NULL));
...
   ar & BOOST_SERIALIZATION_NVP(m_Vector); //
std::vector
}
Got everything working but now an issue has come up:
Someone wants to add a new class but it is not part of this
package that is doing the serialzation.  I want to
avoid
what I call "dependency hell", is there a way for that new
class to get registered someplace other than in this
function?
Thanks for any help,
Kauai
