Problems decoding on Raspberry Pi4

[thomz0r]

Hi team ,
just started to use my Pi4 as portable SDR few days ago , and times comes to decode digital voice .
i compiled and installed mbelib and DSDcc with following Cmake options
DUSE_MBELIB=ON -DLIBMBE_INCLUDE_DIR=/usr/local/include/ -DLIBMBE_LIBRARY=/usr/local/lib/arm-linux-gnueabihf/libmbe.so

I can decode prefectly Dstar sample , and none of other sample are working , ie :
pi@raspberrypi:~/dsdcc $ sox -t s16 -r 48k -c 1 samples/dmr_it_8.dis -t s16 -r 48k -c 1 - | dsdccx -i - -fa -o - | play -q -t s16 -r 8k -c 1 -

End of process
pi@raspberrypi:~/dsdcc $

also tried with DSD and i have issue to ( no audio ) .

any clue to help me moving forward ?

Hello
I've same problem on my laptop under Fedora 36.
Compiler : C++17.

When compile, i've warring with unuse variable. I'm make modification in source to have no error and/or warrning.
I'm sur is dirty solution but that work for me. Correct work with samples files.

I hope little help and resolve problem.
