pyzmq-static 2.0.7a

Statically linked ØMQ / 0MQ / ZeroMQ for Python

This package provides a statically-linked version of the zmq Python library, which is the official interface between Python and the ØMQ messaging library. You can find the exuberant ØMQ web site here:

http://www.zeromq.org/

The official distribution for the zmq library is called pyzmq here on PyPI, and is maintained by Brian E. Granger:

http://pypi.python.org/pypi/pyzmq/

This pyzmq-static distribution was created by Brandon Craig Rhodes after he became frustrated with having to install both libuuid-dev and ZeroMQ itself on every machine where he then wanted to install pyzmq. Whether you use Linux or Windows, this package should download and compile with a quick pip install assuming that you have the normal tools in place for building Python extension modules at all (which are, specifically, the GNU C and C++ compilers for POSIX systems, and the free Microsoft Visual C++ 2008 Express for Windows machines).

Warning

This Python package is statically linked against ØMQ, which means that it carries its own copy of ØMQ around inside of it.

If your Python program imports any other libraries or modules that themselves link against ØMQ, then they will find themselves talking to a different copy of the message queue libraries than your program does. The two copies of ØMQ might have different versions; they might lack shared copies of data structures that would be necessary to coordinate in-process queues (though I think that ØMQ has avoided these); or they might break altogether, depending on how they and your operating system’s dynamic linker decide to behave.

But, really, what is the likelyhood of that? This static version has worked fine for me so far!

Copying

This package uses a “setup.py” file, which Brandon Craig Rhodes happily offers under a BSD license, to build a shared library built from three different source distributions. To use the result, you must adhere to the licensing terms of all three pieces of software, which are as follows:

• The UUID routines from “util-linux-ng”: BSD

• The “zeromq” source: LGPL

• The “pyzmq” source: LGPL

So, okay, those are not very restrictive licensing terms. But still. See the source files themselves for more information.

Development

The original source of pyzmq-static lives at Bitbucket:

http://bitbucket.org/brandon/pyzmq-static

You can report bugs and problems, which Bitbucket euphemistically calls “issues”, here:

http://bitbucket.org/brandon/pyzmq-static/issues

The development tree is accompanied by a small get.sh shell script that re-fetches all of the original source distributions for ØMQ, pyzmq, and libuuid, and rebuilds the include and src directories using the original files. When new versions of these dependencies come out, we will update the get.sh script, tweak the result until it compiles cleanly under Linux and Windows, and release a new version of pyzmq-static.
