You can find more information on these two pages:

http://jenkins.gnuradio.org/manual/doxygen/page_ctrlport.html

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


ControlPort was reintroduced just after the 3.7.7 release so we had time to
test it, but it will be available in the upcoming 3.7.8 release. The manual
page linked above is from our weekly development builds.

This points you to two apps that are installed with ControlPort:
gr-perf-monitorx and gr-ctrlport-monitor. Other good places to look for
usage is in our QA code. Look in gr-blocks
for qa_cpp_py_binding.py, qa_cpp_py_binding_set.py,
and qa_ctrlport_probes.py.

Tom

ControlPort is written in python ?

When I ran qa_ctrlport_probes.py. I got a segmentation fault first time. Then I ran the other two qa codes they passed successfully without any core dump. When I ran qa_ctrlport_probes.py again it passed successfully.

What could be the cause?  I thought I should share because it is a new release and is in testing stage.

There is a bug in Thrift 0.9.2 that I'm going to guess is the cause of that seg fault. See our notes on building Thrift and the patch that we have for it:

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

I believe that patch has been accepted, but after the 0.9.2 release.

Tom

 

I am going to apply the patch to thrift. Should I remove and reinstall gnruadio too after applying patch.

Bob

No, no need. That's the magic of dynamic linking.

Tom

Applying the patch was not successful. I am using thrift 0.9.2.
address@hidden:~/thrift$ thrift -version
Thrift version 0.9.2


What version of thrift this patch belongs too?

address@hidden:~/thrift$ patch -p1 < thrift-codebase-shutdown-patch.diff
