Subject Re: ZeroMQ licensing in Apache MXNet
Date Thu, 06 Jul 2017 19:09:13 GMT
It's optional for MXNet to use ZeroMQ. Even if it is enabled, the source
codes of MXNet will not contain any codes from ZeroMQ except for
"include<zmq.h>" and calling zeromq's APIs. But if we want to ship the
binary, it will link against libzeromq.a
