Ravi,
It looks like you have a very old version of zmq.hpp header. Both of those
methods are templates added along with C++11 support [1].
Check if you have them, if not, you can either update the header or use
non-template methods:
int timeout = 1000;
zmq_socket.setsockopt(ZMQ_RCVTIMEO, &timeout, sizeof(timeout));
unsigned char* byteptr = static_cast<unsigned char*>(msg.data());
