Re: [Discuss-gnuradio] RTTY receiver

[Kyeong Su Shin]

Hello Barry:

I replicated this on my Pi, and "sudo ldconfig" fixed it. Could you try that, if you haven't already

The runtime path of the swig source library is set to "" like in yours, but it does not prevent the script from running (at least on my machine (tm)).

(I always run "sudo ldconfig" after installing a GNU Radio module, because many modules simply require that to function properly.)

Regards,

Kyeong Su Shin

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

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
