Hmm - a const object is one that can't be changed once created. If you think about it, this conflicts with what serialization is. If in spite of this, you still want to do it, it is possible. Use const_cast. Also there information in the documentation regarding this. Robert Ramey Soumen wrote:
Hi,
I'm using gcc 4.2.2 and boost 1.35. If I try to serialize pointer to some const objects, I'm getting compilation problem. Is there any limitation? Or I need to do certain things differently? I couldn't figured any solution over net. If there already exist any topic which points to solution, please point me to that. Otherwise, guide me to resolve the problem at hand. I'm new to boost.
Say, my data member in the class myClass is
const myType *ptr;
In the serialize() routine, I'm doing it in following way:
template< class Archive > void myClass::serialize(Archive &ar, const unsigned int version) { ar & ptr;
// I've tried "ar & const_cast< myType* >(ptr)" and // "ar & (myType *) ptr" as well - it didn't work
/* serialize other members */
}
