Introduction & Design Goals
===========================
cppzmq is a C++ binding for libzmq. It has the following design goals:
- cppzmq maps the libzmq C API to C++ concepts. In particular:
- it is type-safe (the libzmq C API exposes various class-like concepts as void*)
- it provides exception-based error handling (the libzmq C API provides errno-based error handling)
- it provides RAII-style classes that automate resource management (the libzmq C API requires the user to take care to free resources explicitly)
- cppzmq is a light-weight, header-only binding. You only need to include the header file zmq.hpp (and maybe zmq_addon.hpp) to use it.
- zmq.hpp is meant to contain direct mappings of the abstractions provided by the libzmq C API, while zmq_addon.hpp provides additional higher-level abstractions.
There are other C++ bindings for ZeroMQ with different design goals. In particular, none of the following bindings are header-only:
- [zmqpp](https://github.com/zeromq/zmqpp) is a high-level binding to libzmq.
- [czmqpp](https://github.com/zeromq/czmqpp) is a binding based on the high-level czmq API.
- [fbzmq](https://github.com/facebook/fbzmq) is a binding that integrates with Apache Thrift and provides higher-level abstractions in addition. It requires C++14.
Supported platforms
===================
- Only a subset of the platforms that are supported by libzmq itself are supported. Some features already require a compiler supporting C++11. In the future, probably all features will require C++11. To build and run the tests, cmake and googletest are required.
- Tested libzmq versions are
- 4.2.0 (without DRAFT API)
- 4.2.5 (with and without DRAFT API)
- Platforms with full support (i.e. CI executing build and tests)
- Ubuntu 14.04 x64 (with gcc 4.8.4) (without DRAFT API only)
- Ubuntu 14.04 x64 (with gcc 7.3.0)
- Visual Studio 2015 x86
- Visual Studio 2017 x86
- Additional platforms that are known to work:
- We have no current reports on additional platforms that are known to work yet. Please add your platform here. If CI can be provided for them with a cloud-based CI service working with GitHub, you are invited to add CI, and make it possible to be included in the list above.
- Additional platforms that probably work:
- Any platform supported by libzmq that provides a sufficiently recent gcc (4.8.1 or newer) or clang (3.3 or newer)
- MacOS X
- Visual Studio 2012+ x86/x64

Build instructions
==================
Build steps:
1. Build [libzmq](https://github.com/zeromq/libzmq) via cmake. This does an out of source build and installs the build files
