Question

I get the following error:

“Error 1 error LNK2019: unresolved external symbol _imp_zmq_init referenced in function “public: __thiscall zmq::context_t::context_t(int)” (??0context_t@zmq@@QAE@H@Z) ZeroMQPlay.obj ZeroMQPlay”

With this C++ code:

include "stdafx.h"
include <zmq.hpp>

int _tmain(int argc, _TCHAR* argv[])
{
 zmq::context_t ctx(1);

 return 0;
}

Heelp!

You have to tell the linker about the ZeroMQ library. If you’ve built ZeroMQ as a VS project, the easiest way is to add the ZeroMQ project to the solution containing your own project and mark your project as dependent on it.
