I am trying to compile the lasted code from github and am getting an error from CMake. It is looking for pyZMQ and not finding it. I tried to install the module but not having much luck - that is it is not simple. Is there a scenario that I can follow? The dependency list does not cite PyMZQ so I am curious if it really needs it. This is on Ubutunu 14.04. Alan - W6ARH ---

I got it complied and working. The key was to install Cython. It is probably worthwhile to add it to the dependency list. Alan From: Nick F.

That’s very strange. Cython isn’t required for either PyZMQ or gr-air-modes. My guess is you have multiple Python versions installed, and PyZMQ got installed to a version that isn’t the one gr-air-modes found. Whatever works! =) –n ---

gr-air-modes did not require it but it was needed to compile libzmq. I’ll check but I am sure all I have is Python 2.7. Cheers, Alan From: Nick F.
