Re: Import Block "bad import syntax"

Hi Jim,

1) Have you done
https://wiki.gnuradio.org/index.php/TutorialPythonFunctions with the
changes I suggested? Did it work?

2) Did you create ~/gr-softrock in the same manner as that tutorial?

3) What is your module going to do? Is it just an audio input from a USB
dongle such as the 'Plugable USB Audio Adapter' I use on my rPi? If so,
you can use the Audio Source block with the appropriate device name for
the USB device. Look at
https://wiki.gnuradio.org/index.php/Simulation_example:_AM_transmitter_and_receiver#AM_transmitter
for an example.

4) Otherwise, it would probably be a lot simpler to use an Embedded
Python Block (https://wiki.gnuradio.org/index.php/Embedded_Python_Block)
for your softrock_usb.py program.

Keep me posted.

P.S. If you 'reply all' it will get included in the Discuss Gnuradio thread.
