Hi,

I have a problem with serializing a derived classes through a pointer to a base class. I tried registering with the syntax from the documentation:

ar.template register_type<derived_one>();

, which works well in case the derived class has a default constructor (just like the example). I just don't know what the syntax is for the case where the derived class does not have a default constructor (if I use the same syntax to register the derived class then I get a compilation error about the fact that there is no. I can provide an example in case this is not clear enough.

Is it an absolute requirement for all derived classes to have a default constructor?

Thank you and best regards,
Dante
