Hi together, inside the application I'm writing is defined a base class and a factory for the creation of instances through a number of plugins. The plugins auto registers when theis shared objects are dynamically loaded from the application. Each plugin instance is derived from a pure abstract interface defined in the application and used from the plugins through an header. The application maintains a list of these plugins as a member of an object. I would like use boost.serialization library in order to serialize the application container object with all the plugins contained. The library reference mentions a plugin case among its 'special considerations', but I couldn't obtain nothing working till now, so that I wonder if I should use instead the 'PIMPL' idiom (mentioned in the 'Case Studies'). I'm neither sure if the PIMPL idiom is the right waym since it would imply the definition of the base class in every plugin (so in every shared object), that means a replication of the same coding. So far, is there a complete example of boost.serialization of plugins with private implementation in shared object? Many thanks in advance Giampiero
