c++ - boost::circular_buffer<unique_ptr<T>>::set_capacity() fails to build -
i'm trying use boost::circular_buffer in code this:
class eventregistry { public: eventregistry() { pendingevents_.set_capacity(max_pending_events); } private: boost::circular_buffer<boost::movelib::unique_ptr<eventdata>> pendingevents_; } however, i'm getting build failure (excerpted):

eventregistry() : pendingevents_(max_pending_events) then compiles fine. clues?

the following compiles fine...
#include <boost/circular_buffer.hpp> #include <boost/move/unique_ptr.hpp> class eventregistry { public: eventregistry() { pendingevents_.set_capacity(10); } private: boost::circular_buffer<boost::movelib::unique_ptr<int>> pendingevents_; }; int main() { return 0; } note i've placed int have eventdata. you're problem related eventdata.
(i don't have enough points, comment...)
edit: oh , check kind of constructors eventdata has! have default constructor??
