How to solve this?

Have you run:

./pybombs env

…and then run:

source …/target/setup_env.sh (alter file path to taste)

The “UHD Source” GRC block uses the file called “uhd_usrp_source.xml”.
Make sure that this is in your GRC path.

To set the GRC path you need to go into the ~/.gnuradio folder and
create a
config.conf file and add the following tweaked with your actual path to
the
“UHD source” block:

[grc]
global_blocks_path = /usr/local/share/gnuradio/grc/blocks

Unfortunately, the file “uhd_usrp_source.xml” doesn’t exist at all.
I’ve searched it in both “/usr/local” and “~/download/gnuradio/target”,
the
file simply does not exists!

Yes, this has been performed.
During gnuradio installation, I configured the prefix to /usr/local due
to
a reason mentioned in
http://gnuradio.4.n7.nabble.com/PyBOMBS-install-gnuradio-3-7-4-td48343.html

Hence, I had performed these:
sudo ./pybombs install gnuradio —> install gnuradio to
/usr/local
sudo ./pybombs env —> refresh settings in
/usr/local/setup_env.sh

source /usr/local/setup_env.sh
gnuradio-companion

With these the uhd becomes not available in GRC.

#6

This means that UHD was not installed correctly.

If running the following doesn’t find anything then hunt down and remove
any ghost version of UHD that makes Pybombs think that it is installed
and
then reinstall it using pybombs:

sudo find / -name uhd_usrp_source.xml
