ZeroMQ

Welcome

The ZeroMQ lightweight messaging kernel is a library which extends the standard socket interfaces with features traditionally provided by specialised messaging middleware products. ZeroMQ sockets provide an abstraction of asynchronous message queues, multiple messaging patterns, message filtering (subscriptions), seamless access to multiple transport protocols and more.

Supported platforms <a name="#platforms"/>

Libzmq is mainly written in C++98 with some optional C++11-fragments. For configuration either autotools or CMake is employed. See below for some lists of platforms, where libzmq has been successfully compiled on.

Supported platforms with primary CI

Note: the platforms are regularly updated by the service providers, so this information might get out of date without any changes on the side of libzmq. For Appveyor, refer to https://www.appveyor.com/updates/ regarding platform updates. For travis-ci, refer to https://changelog.travis-ci.com/ regarding platform updates.
