The ZMQ "draft version" contains unstable but useful features. Notably it includes support for UDP.

We'll focus development on libzmq-4.3.2; unstable here means the API might change in future versions for the "draft" interfaces, but we'll just use 4.3.2 for ComPair.

• Download the release from: https://github.com/zeromq/libzmq/releases/tag/v4.3.2
• After unpacking, run:

./configure --enable-drafts --prefix=$LIBZMQ_INSTALL_PREFIX
make && make install

If you want to have pyzmq with UDP/other-draft-feature support, you will need to build pyzmq yourself. No pip install. Sad face emoticon.

• Download pyzmq: https://github.com/zeromq/pyzmq
• Configure to use drafts, and point to where you installed libzmq. In my example, I installed to $LIBZMQ_INSTALL_PREFIX

python3 setup.py install --enable-drafts --libzmq=$LIBZMQ_INSTALL_PREFIX --prefix=PYZMQ_INSTALL_PREFIX

cppzmq provides a header-only binding to zmq. This is nice... no linking or compiling, just make sure the single header file is in your include path.

Source is available at https://github.com/zeromq/cppzmq.

If you want cppzmq to include the draft stuff, make sure that somewhere before including <zmq.hpp> that you have the following line:

#define ZMQ_BUILD_DRAFT_API

You could also edit your zmq.hpp file to define the macro if you feel so bold.
