Re: Tutorial on Hier Block and Parameters

The output is

echo $PYTHONPATH
:/home/grctut/ the folder where I am saving working grc files.

However, I am able to use GRC for other purposes normally. I notice that GRC blocks (.yaml files) are in /usr/share/gnuradio/grc/blocks/ folder. Also there is no .grc_gnuradio file in my home directory. However, there is a .gnuradio folder with a prefs folder and config.conf and grc.conf files. prefs folder has a vmcircbuf_default_factory file.

Yes, that the generated hier block files go to the working directory of
~/.grc_gnuradio is a known bug.

See:
https://github.com/gnuradio/gnuradio/pull/5547

What is the result of

echo $PYTHONPATH
