I am yet not sure if the problem is related to ROS or not. Let me explain it briefly. I am setting the ZeroMQ socket timeout option in the following way: zmq_socket.setsockopt(ZMQ_ RCVTIMEO, &timeout, sizeof(timeout)); It is showing this error: talker_zmq.cpp:21:25: error: ‘ZMQ_’ was not declared in this scope I also notice that the catkin_make command is showing a suspicious following error message: make[2]: *** No rule to make target `/usr/local/lib/libzmq.so', needed by `/home/ravi/ros_ws/devel/lib/beginner_tutorials_ravi/talker_zmq'. Stop.
