[zeromq-dev] Building PyZmq on Mac

[Thomas Maslach]

I'm attempting to build pyzmq where it'll automatically put the zeromq libraries within in the pyzmq 'zmq' folder.

I am using my own build of python located in my home dir.  It will move around.

I first did the following:

../python27/python setup.py configure -zmq=../zeromq-4.0.4
../python27/python setup.py install

This installs everything, but does not put libzmq.dylib into the zmq folder.  Running otools -L libzmq.dylib also gives the id of that dylib as the full path to zeromq-4.04 + libzmq.3.dylib.  (Sorry about any confusing terminology - my mac knowledge is slim).

After looking on line some and at the setup.py code, I tried the following:

../python27/python setup.py configure -zmq=../zeromq-4.0.4
../python27/python setup.py bdist

It looks like bdist will make the bundle_libzmq_dylib property in setup.py return True, which will copy libzmq.dylib into pyzmq's zmq folder and call install_name_tool to change the id of zmq.  This seems to work.  But, I then get the following error in the output.  It seems that it is trying to build in the build folder, which means libzmq isn't up a level.

Any idea of how I use setup.py to accomplish what I want?  I just want a pyzmq build with my zeromq linked into it, and the python folder can be located anywhere on disk (and not necessarily on my machine).  I believe I can manually go to all the *.so files and call install_name_tool to redirect to my libzmq.  But, that doesn't seem like a clean solution.

Any help would be greatly appreciated - I've struggled on this for quite a bit!

Here is the output I got from running ../python27/python setup.py bdist

Fatal: Falling back on bundled libzmq, but setup.cfg has explicitly prohibited building the libzmq extension.
