error: 'zmq' has not been declared

When building/compiling I am getting this error:

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

main.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;
}

Anyone got any ideas on how i can fix this?

You need to add #include <zmq.hpp> This will include the C++ api of libzmq. However, in the zmq verions 2.x version it was included with the install, nowadays in the zmq-3.x.y version it is not shipped with the library anymore, as you can see from http://github.com/zeromq/zeromq3-x/raw/master/NEWS

The C++ api was excluded from the core library since the less is more strategy from zeromq. It is still downloadable from: https://github.com/zeromq/cppzmq/blob/master/zmq.hpp

This header is written around all C structures and functions the C API zeromq, therefore the entire C++ API is a single headerfile. Downloadable from the link above.

If you wrote zmq.h by yourself, it should be "zmq.h".
