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

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Note: the platforms are regularly updated by the service providers, so this information might get out of date without any changes on the side of libzmq.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

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.

Installation of binary packages

Linux

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.

Latest releases

DEB

RPM

Bleeding edge packages

DEB

RPM

Example: Debian 9 latest release, no DRAFT apis

echo "deb http://download.opensuse.org/repositories/network:/messaging:/zeromq:/release-stable/Debian_9.0/ ./" >> /etc/apt/sources.list
wget https://download.opensuse.org/repositories/network:/messaging:/zeromq:/release-stable/Debian_9.0/Release.key -O- | sudo apt-key add
apt-get install libzmq3-dev

OSX

For OSX users, packages are available via brew.

brew install zeromq

Installation of package manager

vcpkg

vcpkg is a full platform package manager, you can easily install libzmq via vcpkg.

git clone https://github.com/microsoft/vcpkg.git
./bootstrap-vcpkg.bat # For powershell
./bootstrap-vcpkg.sh # For bash
./vcpkg install zeromq

Build from sources

To build from sources, see the INSTALL file included with the distribution.

Android

To build from source, see README file in the android build directory.

Resources

Extensive documentation is provided with the distribution. Refer to doc/zmq.html, or "man zmq" after you have installed libzmq on your system.
