[Discuss-gnuradio] tests for ctrlport on macOS?

[Michael Dickens]

I recently had a MacPorts ticket to enable +ctrlport. After updating
thrift to 0.10.0, along with a patch  to fix gr-fec's possible use of
c++11's 'constexpr', I got GR to build with ctrlport enabled. Ticket
fixed, since the issue was in MacPorts.

Running "make test" results in failures in the ctrlport tests:
qa_cpp_py_binding, qa_cpp_py_binding_set, qa_ctrlport_probes. Each one
comes up with "Ctrlport Key called with unregistered key" and raising a
runtime error "recv_getKnobs" in
"gnuradio-runtime/include/gnuradio/rpcserver_thrift.h". Disabling the OS
firewall doesn't change the error.

I'm wondering if others use ctrlport and thus if this error is specific
to macOS / Mac OS X, or maybe if the GR code needs updating for the
newer Thrift? Are there examples of using ctrlport that I others use for
testing / evaluation of this feature?

Thanks! - MLD
