Development master

You can get the latest development master at any time via git. If you're developing new apps, we recommend you test against the master regularly. On Linux or OS/X, run ./autogen.sh after cloning this repository.

Previous releases

All past and current releases, including historic versions, are online at download.zeromq.org, with MD5 and SHA-1 checksums.

Other software

If you are working in C/C++ you will want to get CZMQ, the high-level C binding, which adds many useful classes on top of ZeroMQ, including UDP and gossip discovery, a reactor, containers, smart sockets, and actors for concurrent programming.

To build on UNIX-like systems

If you have free choice, the most comfortable OS for developing with ZeroMQ is probably Ubuntu.

  1. Make sure that libtool, pkg-config, build-essential, autoconf, and automake are installed.
  2. Check whether uuid-dev package, uuid/e2fsprogs RPM or equivalent on your system is installed.
  3. Unpack the .tar.gz source archive.
  4. Run ./configure, followed by make.
  5. To install ZeroMQ system-wide run sudo make install.
  6. On Linux, run sudo ldconfig after installing ZeroMQ.

To see configuration options, run ./configure --help. Read INSTALL for more details.

To build on Windows

  1. You need Microsoft Visual C++ 2008 or newer.
  2. Unpack the .zip source archive.
  3. In Visual C++ open the solution builds\msvc\msvc.sln.
  4. Build the solution.
  5. ZeroMQ libraries will be in the lib subdirectory.

Language bindings

ZeroMQ comes with the low-level C API. High-level bindings exist in 40+ languages including Python, Java, PHP, Ruby, C, C++, C#, Erlang, Perl, and more.

Pure Language Stacks

ZeroMQ also comes in a pure Java stack called JeroMQ, and a pure C# stack called NetMQ. These are both official projects and supported by the ZeroMQ community.
