[Discuss-gnuradio] fg.run() doesn't return if gr.head() is used

[Dawei Shen]

Hey Guys

I used gr.head() as my source, so I assumed fg.run() should be able to return, but it doesn't. Anybody has any idea which could be the reason? Here is the error message if I press ctrl+C to stop the program.


    mygraph.run()
  File "/usr/local/lib/python2.5/site-packages/gnuradio/gr/flow_graph.py", line 113, in run
    self.wait ()
  File "/usr/local/lib/python2.5/site-packages/gnuradio/gr/flow_graph.py", line 104, in wait
    self.scheduler.wait ()
  File "/usr/local/lib/python2.5/site-packages/gnuradio/gr/scheduler.py", line 68, in wait
    thread.join(timeout)
  File "/usr/lib/python2.5/threading.py", line 569, in join
    self.__block.wait(delay)
  File "/usr/lib/python2.5/threading.py", line 233, in wait
    _sleep(delay)
KeyboardInterrupt


Thanks.
