Re: [Discuss-gnuradio] RTTY receiver

[Barry Duggan]

Here is my current status.

I performed the following commands in the 
/home/pi/gr-radioteletype/build directory:

pi@raspberrypi:~/gr-radioteletype/build $ make clean
pi@raspberrypi:~/gr-radioteletype/build $ cmake ../

Then when I execute the flow graph, I get

/home/pi/gr-radioteletype/examples/rtty_demod.py

    __import__(name)
ImportError: No module named _radioteletype_swig

So even though 'cmake' figured out the install path, the install script 
set the runtime path to "".
Is there a command line define where I need to specify the runtime path?

Thanks, Barry
