Re: [Discuss-gnuradio] Error building with new ZMQ

[Michael Dickens]

If I change all of the "zmq.hpp" #include lines to be instead "zmq.h", then I 
get the following errors:
{{{

So ... it seems like unless there's some standard way to get zmq.hpp then we 
won't be using gr-zeromq on OSX.  Any ideas?  Can someone send me that file? -
