Hi, I'm using boost::serialization to store my data from my application. Everything is working nice, but I just can't store my class loaded from plugin. I know there is a lot of discussion here on this topic, I did read a lot of it. I also looked in /examples and /test directories but I still don't fully understand what exactly should I do... So I have abstract class i main application and derived class in plugin. As I understand it, all I have to do to make it work is: 1) #include <boost/archive/text_oarchive.hpp> #include <boost/archive/text_iarchive.hpp> 2) use BOOST_CLASS_EXPORT macro in plugin_class.cpp but I'm still getting unregistered class exception. Can someone help me please? I know I'm doing something wrong but I can't figure it out. I'm running Ubuntu Lucid with boost 1.40... -- View this message in context: http://old.nabble.com/Class-from-plugin-serialization-fails-tp28380080p28380...
