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.

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.

Note: the platforms are regularly updated by the service providers, so this information might get out of date without any changes on the side of libzmq.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.

At the time of writing, no explicit reports have been available. Please report your experiences by opening a PR adding an entry or moving an entry from the section below.

Under "last report", please name either the SHA1 in case of an unreleased version, or the version number in case of a released version.

Note: this list is incomplete and inaccurate and still needs some work.

For some platforms (Linux, Mac OS X), prebuilt binary packages are supplied by the ZeroMQ organization. For other platforms, you need to build your own binaries.

For Linux users, pre-built binary packages are available for most distributions. Note that DRAFT APIs can change at any time without warning, pick a STABLE build to avoid having them enabled.

For OSX users, packages are available via brew.
