OOT Modules not showing up in GNURadio

Question

Followed the instructions here to create an OOT module -

https://wiki.gnuradio.org/index.php/Guided_Tutorial_GNU_Radio_in_Python

The cmake etc all works fine -
`cmake ../
make
sudo make install
sudo ldconfig`

But when I load up GNURadio the modules don’t appear. This is the output of the make install -

`gnuradio@cjswin ~/gr-tutorial/build >> sudo make install
[ 66%] Built target pygen_python_98246
[ 66%] Built target pygen_apps_9a6dd
[100%] Built target doxygen_target
Install the project…

Some of the other forums have suggested changing the config.conf file, so I have gone to -

/home/.gnuradio/config.conf and added in the following (looking at the make install above my xml file seems to be going somewhere totally different to where the other gnuradio xml files are)
`[grc]
local_blocks_path=/home/gnuradio/pybombs/usr/share/gnuradio/grc/blocks`

The other xml files are here - `/usr/share/gnuradio/grc/blocks`

I have also tried doing the cmake with a prefix to that location -

`cmake -DCMAKE_INSTALL_PREFIX=/usr/share/gnuradio …/`

But this also has made no difference, i still can’t see the module when I"m in GNURadio.

Very much appreciate any help

Answer 1

Try to create your OOT module in the src folder of your pybombs prefix, for example: When type pybombs install gnuradio this is installed into ~/pybombs/default/src/ (in this example the prefix name is default) so try to create your OOT module in this directory (~/pybombs/default/src/gr-your-OOT/) and continues working like you normally do it (this option works for me ...)

Answer 2

/home/.gnuradio/config.conf and added in the following (looking at the make install above my xml file seems to be going somewhere totally different to where the other gnuradio xml files are)

[grc]
local_blocks_path=/home/gnuradio/pybombs/usr/share/gnuradio/grc/blocks

The file that you need to edit is /home/gnuradio/.gnuradio/config.conf, you are missing one sub-directory.

cmake -DCMAKE_INSTALL_PREFIX=/usr/share/gnuradio …/

The correct install prefix in your case is /home/gnuradio/pybombs/ and not /usr/share/gnuradio/. If you really want your module to be installed in /usr and blocks definitions in /usr/share/gnuradio/grc/blocks (I do not recommend this) then the prefix should be /usr/ (without /share/gnuradio)
