I'm really confused about the way I should compile the python example, I'm following the README ,but the cmake ( cmake .. -DSDRPLAY=ON) command generate a rather cryptic error :

CMake Error: The following variables are used in this project, but they are set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the CMake files:
SDRPLAYLIB_INCLUDE_DIR
used as include directory in directory /home/andrea/dab-cmdline/python-example

Ok, I managed to compile this , I was using the wrong define, using -DRTLSDR I can compile it.
but now I have another problem , if I run python3 cmdline.py -d 5 -c 12A -p "Fix Radio"

I get :

device restarted
ofdm word gestart
no DAB signal detected, giving up
no ensemble found, giving up

I had to choose python3.4m instead of python3.5m to make it working on the raspberry pi .

I'm trying to make a digital radio receiver without a screen attached, I'm really finding difficult, there is not a single working or ready piece of software to use the raspberry as DAB receiver via command line, I can't get it...

Have you tried eti-stuff (including eti-cmdline) as well?

This is much easier and stable.

hey andimik , thank!

Looks like that eti-stuff is more polished and stable :)

THANKS a lot @andreacampanella.

I was struggling to get this library/example-1 working for the exact same purpose as you do: having a stand-alone -without screen- DAB receiver/player. I was using the wrong define too.

Although the python-example still fails

$ python3 cmdline.py 
device restarted
ofdm word gestart
no DAB signal detected, giving up
no ensemble found, giving up

(and installing python3.4 gives me import errors as numpy/multiarrays/... and I don't know how all this relates to python3.5, the latest and greatest on the Raspbian Stretch)

I'm now able to compile example-1 (after I patched it...

$ git diff
diff --git a/example-1/main.cpp b/example-1/main.cpp
index 010f85b..aa83ddd 100644
--- a/example-1/main.cpp

So, cmake .. -DRTLSDR=ON (in the created build directory of example-1) followed by make, gives dab-rtlsdr. Note: during my struggle I installed/removed a lot of packages; hang-on while building/compiling :-)

For example

$ ./dab-rtlsdr -C 12C -P "NPO Radio 2"

I don't know (yet) what ALSA complains about, but it just works!!!
