You cannot continue to use zmq sockets after a fork - you have to take care in your application that no sockets created before the fork will be used by any calls in the child process.​ ___ zeromq-dev mailing list zeromq-dev@lists.zeromq.org

Re: [zeromq-dev] pyzmq: using libzmq functions from cython

Depending on the nature of your code, it should be okay as long as pyzmq is imported first, which loads the bundled libzmq into RTLD_GLOBAL if there is one. It is meant to support use from Cython, but I confess that I am only aware of one such project (gevent-zeromq), which has since been

Re: [zeromq-dev] What's the easiest way to install PyZMQ on a Windows box running Python 2.5?

I never made an MSI for 2.5, since it was deprecated before pyzmq had any binary installers. Note that you don't have to build pyzmq on the machine itself, you can run `python setupegg.py bdist_msi` (or bdist_egg) on your own Windows machine or VM, then pass that MSI to the target machine.
