I get these errors trying to build ZWSSOCK in X64/Release config:

I've tried all kinds of build configurations, nothing has gotten me closer than this.

Make sure you are using CZMQ not newer than 3.x - IE at most https://github.com/zeromq/czmq/releases/tag/v3.0.2

This project uses old 3.x APIs of CZMQ, which were deprecated and removed starting with version 4.0, and that's why you are seeing those build errors I assume.

I was able to build with latest CZMQ/LibZMQ on ubuntu 16.04, I made these changes to fix the compatibility issues:

It seems to me to be a linker/include path issue, it is not clear how to resolve the dependencies in Visual Studio though
