That's just an error.  You will get exactly the symptom you describe if 
you're using Visual C++ and using MySQL++ in a DLL.  If that's your 
situation, I would just add the MYSQLPP_EXPORT declaration and rebuild 
the library.  You should also do it for Connection::api_version().

This will be fixed in the next version.

If you're on some other platform, then I'll need more details to know 
what's going wrong.
