构建/编译时出现此错误：
C:\Ethe\main.cpp: In function 'int main()':
C:\Ethe\main.cpp:11:4: error: 'zmq' has not been declared
C:\Ethe\main.cpp:11:19: error: expected ';' before 'context'
C:\Ethe\main.cpp:12:4: error: 'zmq' has not been declared
C:\Ethe\main.cpp:12:18: error: expected ';' before 'socket'
C:\Ethe\main.cpp:14:4: error: 'zmq' has not been declared
主.cpp：
#include <zmq.h>
#include <iostream>
#include <string>
int main()
{
std::string tip;
std::cout << "Enter Target IP: ";
std::cin >> tip;
zmq::context_t context (1);
zmq::socket_t socket (context, ZMQ_REQ);
std::cout << "Connecting to " << tip << std::endl;
zmq::socket.connect ("tcp://"+tip+":5555");
return 0;
}
有人对我如何解决这个问题有任何想法吗？
