A cross-platform C++ library to publish and subscribe for events. Applications can discover each other automatically through the integrated ZeroConf protocol, or through explicit addressing using hostname and port. A defined vocabulary defines semantics for the published events.

ZeroEQ provides the following major features:

• Publish events using zeq::Publisher
• Subscribe to events using zeq::Subscriber
• Asynchronous, reliable transport using ZMQ
• Automatic publisher discovery using Zeroconf
• Serialization of events using flatbuffers

ZeroEQ is a cross-platform toolkit, designed to run on any modern operating system, including all Unix variants. ZeroEQ uses CMake to create a platform-specific build environment. The following platforms and build environments are tested:

• Linux: Ubuntu 14.04, RHEL 6 using gcc 4.8
• Windows: 8 using Visual Studio 12
• Mac OS X: 10.9 and 10.10 using clang 6

ZeroEQ requires the following external, pre-installed dependencies:

• ZeroMQ 4.0 or later
• Boost (tested with 1.54) for unit tests
