Of course, if I replace B const *pc by B *pc, then the code works correctly.What can I do to serialize pointers to const data ?
Regards,
Or you could replace this above with: ar & const_cast<B *>(pc); (or maybe const_cast<B * &>(pc)
I really do not understand why I would have to do that.
But that would override the normal meaning of "const" as applied to a member variable.
In this case, the member variable is not const. It's not like in http://www.boost.org/libs/serialization/doc/serialization.html#const . It's just a non const pointer that refers to a non const class defined elsewhere, but that promise not to modify that class himself.
correct. Its a non-const pointer to a const object. But if the object is const then it is prohibited from being modified. Serialization has no special privleges in this regard. So loading it traps at compile time - just as would anyother attempt to modify the object that B is pointing to.
You really have to ask yourself what you want serialize to include.
Could you please explain this point ? I do not understand what you mean.
If you want the object pointed to by pc to be modifiable by serializaltion then it shouldn't be const. Robert Ramey
