this is on a Fedora 19-64.

Any help is greatly appreciated.

Looks like the server isn't being started. When you run cmake, you should see that under enabled components, you have:

* gr-ctrlport

** thrift

That tells you ControlPort is enabled and the Thrift backend will be built for it. You can also tell by looking at gnuradio/config.h to see if GR_RPCSERVER_ENABLED and GR_RPCSERVER_THRIFT are defined there.

My guess is that cmake isn't picking up Thrift. It requires version 0.9.2 to run. You can get some info on building this yourself here:

http://gnuradio.org/redmine/projects/gnuradio/wiki/ControlPort

I also just pushed a new apache-thrift recipe to PyBOMBS today.
