I'm tring to run jubatus-msgpack-rpc example code(https://github.com/jubatus/jubatus-msgpack-rpc/tree/master/cpp , simple client and simple server) in clion and keep getting errors . here are error message

here is the code

 class myserver : public msgpack::rpc::server::base {  public:      void add(msgpack::rpc::request req, int a1, int a2)      {          req.result(a1 + a2);      }    public:      void dispatch(msgpack::rpc::request req)      try {          std::string method;          req.method().convert(&method);            if(method == "add") {              msgpack::type::tuple<int, int> params;              req.params().convert(&params);              add(req, params.get<0>(), params.get<1>());            } else {              req.error(msgpack::rpc::NO_METHOD_ERROR);          }        } catch (msgpack::type_error& e) {          req.error(msgpack::rpc::ARGUMENT_ERROR);          return;        } catch (std::exception& e) {          req.error(std::string(e.what()));          return;      }  };    int main()  {      myserver svr;      svr.instance.listen("0.0.0.0", 9090);      svr.instance.run(4);  // run 4 threads  }  

why it's keeping get errors and how to slove it ?
