If what you want is simply to connect to AMQP broker, you can actually 
do without zmq_server altogether.

All you have to do is implement a dummy directory service. That will use 
the connection string you supply instead of treating it as symbolic name 
and asking zmq_server to resolve it. The code can be found here:


Then modify the locator cration in libczmq/zmq.cpp like this:

- context->locator = new zmq::locator_t (host_);
+ context->locator = new zmq::dummy_locator_t;
