It has to be outlined, in the source.cpp:

#include <memory>

class Book { struct implementation; std::unique_ptr<implementation> impl_; public: ~Book(); Book(); };

You could probably do // hpp class Book { struct implementation; std::unique_ptr<implementation, void(*)(implementation*)> impl_; public: Book(); }; // cpp Book::Book(): impl_( new implementation, checked_delete<implementation> ) {}
