This works just fine.

The only problem is that the boost export macro doesn't work so you have instanciate the underlying code explicitly.

Hi,

I've been searching the archives but am not finding an answer... Is there any way to serialise D<> via a pointer to its base B when the types used to parameterise D<> are not known in advance? i.e. How do I register D<> with the serialisation library?

For Example...

struct B{ virtual void fn() =0; };

template<typename T> struct D : B{ virtual void fn(){}; };

B* b = new D<char>(); .... anArchive & b;

Thanks,

Richard.
