This optional shared library isolates mbelib and the imported DMR core from the Lazarus application. It intentionally does not depend on PulseAudio, ncurses, libsndfile or the DSD-FME command-line frontend.

Build on Linux:

cmake -S native/dmr -B build/dmr -DCMAKE_BUILD_TYPE=Release
cmake --build build/dmr

The Pascal burst/FEC layer extracts three row-major char[4][24] AMBE+2 frames from each selected voice-slot burst and feeds them through this ABI. Decoded 8 kHz mono PCM is resampled to EWSDR's 48 kHz speaker/web route.

For a build-tree run, either copy libewsdr_dmr.so beside the EWSDR executable or add build/dmr to LD_LIBRARY_PATH. cmake --install build/dmr installs the adapter system-wide. The GUI and daemon remain usable (with metadata but no voice) when this optional library is absent.
