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.

Jenkins cross-build for Windows x64

Use jenkins/build-mbelib-win64.sh in a Jenkins job that checks out mbelib. It creates install-win64 with mbelib.h, the import library, libmbe.dll, and the MinGW runtime DLLs.

Configure the mbelib job to archive install-win64/**. In the EWSDR job, copy that artifact to deps/mbelib and then run native/dmr/jenkins/build-ewsdr-dmr-win64.sh before lazbuild. The script expects the resulting prefix at $WORKSPACE/deps/mbelib/install-win64, builds from $WORKSPACE/native/dmr, and stages the DLL bundle in $WORKSPACE/bin/x86_64-win64 beside the future ewsdr.exe. All paths can be overridden with environment variables.

Declarative/Scripted Pipeline example for the artifact transfer:

copyArtifacts(
  projectName: 'mbelib',
  selector: lastSuccessful(),
  filter: 'install-win64/**',
  target: 'deps/mbelib'
)
sh 'native/dmr/jenkins/build-ewsdr-dmr-win64.sh'
