Re: GNUradio 3.8: ModuleNotFoundError: No module named 'myModulename'

You need to install OOT's into the same directory that GNU Radio is installed in. You can get the correct directory with this command:

gnuradio-config-info --prefix

Then use the result in your CMake invocation. Since I believe you installed from the PPA, then the prefix will be /usr. So the CMake command would be:

cmake -DCMAKE_INSTALL_PREFIX=/usr ../

Before you do this, you should uninstall your current build.

sudo make uninstall

And then delete the contents of the build directory (make sure you're in the build directory).

rm -rf *

Hello community!

I just updated my complete OOT module (named bcsi)  from gnuradio 3.7 to 3.8, and I could make and install  without errors.

Using version 3.8, I created every block with gr_modtool (and then copied-pasted the .cc and .h code from 3.7 version to 3.8)

However, python will not find my module. I already did some basic debugging.

In the /build directory, I already run

$cmake ..

.........

-- Configuring done
-- Generating done
-- Build files have been written to: /home/Documents/gr-bcsi/build

$make

$sudo make install

$sudo ldconfig

I can see the modules appear in the grc GUI, but still cannot find my module.

$ python3
Python 3.6.9 (default, Nov  7 2019, 10:44:02)
[GCC 8.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import gnuradio
>>> import bcsi
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'bcsi'
>>>

Any advice would be welcomed!

Best
