I am using Boost to serialize pointers of a base class which points to instances  of a derived template class. I am using boost 1.7.0 and running it on Ubuntu 16.04.

The source code of the example is available at https://github.com/PritamMG/Boost-Serialization-Example

My example has a base class Bar_A (definition available in include/Abstract.hpp) which has a virtual function toStr(). It has two derived classes Bar_B and Bar_C. Bar_B is a template class.

I have registered the derived classes in sc/Test.cpp. Class ObjectNew (include/Object.hpp) has a member pointer of type Bar_A which points to instances of classes Bar_B and Bar_C.

I get an error as "unregistered class".  I am not sure for which class do I get this error message.

There is also an issue of non-default. If Bar_B does not have a default constructor, save_construct_data and load_construct_data are over-ridden and there I run into an error "too many template-parameter-lists".

How do I define these functions? 

Thanks,

Pritam
