Just use a smart pointer instead of a raw pointer. The following
compiles as expected.
#include <fstream>
#include <boost/archive/text_oarchive.hpp>
#include <boost/archive/text_iarchive.hpp>
#include <boost/serialization/shared_ptr.hpp>
class A {
public:
friend class boost::serialization::access;
template<class Archive>
void serialize(
Archive& ar,
const unsigned int version
) {
ar & aptr;
}
private:
boost::shared_ptr<A> aptr;
};
int main() {
std::ofstream ofs("archive");
boost::archive::text_oarchive oa(ofs);
const A a;
oa << a;
return 0;
}
