Thank you for the response.
I would like to use as GRC blocks the blocks that I create as described
in “How to Write a Signal Processing Block”. This is a somewhat
unconventional situation in that I need a way for an “installed”
application (i. e. grc) to use a locally created component, sort of the
opposite of the normal situation. I think the XML file for the block
should look something like:
When I copy this file into the directory where GRC stores the block XML
files (/usr/local/share/gnuradio/grc/blocks), GRC makes a “Square2”
block available for use. However, when I attempt to execute a flow
graph that includes this block, it fails as follows:
Traceback (most recent call last):
File “/home/kurt/gnuradio/grc/wav_file_to_speaker.py”, line 17, in
ImportError: No module named howto
Where I need help is that I don’t know how to set up python and/or
environment so that python can import these components.
Thanks again for any help you can provide.
