Re: How to enable local OOT modules

[Volker Schroer]

Hi Ivan.

I forgot to mention:

Have a look at ~/.gnuradio/config.conf

There is a sectioo

[grc]

This section should contain something like

global_blocks_path = /usr/local/gnuradio/share/gnuradio/grc/blocks
local_blocks_path = /usr/local/oot3/share/gnuradio/grc/blocks

Instead of setting GRC_BLOCKS_PATH

you can set local_blocks_path which should be evaluated in both cases.

Hi Volker!
In order to see the local blocks in GRC, I also set $GRC_BLOCKS_PATH.
Based on your suggestions, at the moment I added the following variable
definitions in .bashrc:
export GNURADIO_OOT_LOCAL_PATH=$HOME/workspace/gnuradio-oot
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$GNURADIO_OOT_LOCAL_PATH/local/lib
export
PYTHONPATH=$PYTHONPATH:$GNURADIO_OOT_LOCAL_PATH/local/lib/python3.10/dist-packages
export
GRC_BLOCKS_PATH=$GRC_BLOCK_PATH:$GNURADIO_OOT_LOCAL_PATH/share/gnuradio/grc/blocks
It works like a charm if I launch gnuradio-companion from terminal.
The problem is that when I launch GRC from gnome shell, local blocks are
not found.
Why does launching GRC from gnome shell bypass $GRC_BLOCKS_PATH?
Thanks for help.

Hello!
You have to set LD_LIBRARY_PATH and PYTHONPATH accordingly.

For example I install my oot's to /usr/local/oot and I set

echo $LD_LIBRARY_PATH
/usr/local/gnuradio/lib64:/usr/local/volk/lib64:/usr/local/libiio/lib64:/usr/local/libad9361/lib:/usr/local/oot/lib64

echo $PYTHONPATH
/usr/local/gnuradio/lib64/python3.11/site-packages/:/usr/local/oot/lib64/python3.11/site-packages/

Hello guys! My aim is to setup a workstation with GNU Radio and a set
of system-wide OOTs installed (managed by the administrator) to be
used by all of the users, while still allowing the users to create
their own OOTs for local experiments and install them in
$HOME/local/. At the moment I installed GNU Radio on Ubuntu 22.04
using apt; I know I can specify to cmake
|-DCMAKE_INSTALL_PREFIX=$HOME/local.| How to get gnuradio aware with
respect to the OOT modules locally installed? Thanks for help! Ivan
