Openvino build not generating libinference_engine_java_api.so

[Madhini123]

Hello ,

I have been trying to build openvino ( .jar) and related (.so ) for my openvino object detection android app.  The .jar is not getting generated. Hence I used the openvino-2023.0-windows-x86_64.jar from dkurt/release git repositories.  The .jar requires the libinference_engine_java_api.so internally and the app gets installed and crashes with this fatal error.

Hence I started building the openvino and openvino_contrib for arm cpu , but in vain. The below jar and .so are not getting generated . I have been stuck with this issue for past 2 months.

libinference_engine_java_api.so  

libc++_shared.so
libopenvino_arm_cpu_plugin.so
libopenvino_gapi_preproc.so
libopenvino_tensorflow_fe.so

and also the .jar .

I have attached the script file using for my build. Currently using a debian VM cloud to build my jar as the virtual VM is hanging because of low RAM .

Please find the script file for your reference.

It would be very great if someone could help me

Hi Madhini123,

Thank you for contacting us.

The creation of the native library file libinference_engine_java_api.so generally occurs on a desktop (or server) environment, not directly within an Android application.

You are using Android Java, which uses Android AAR, and it will produce:

• openvino-android.aar
• libopenvino.so

Hi Zul,

Thanks for responding.  I shall build openvino on windows environment with the below cmake command

cmake -S %OPV_HOME_DIR%/one-tbb ^
-B %OPV_HOME_DIR%/one-tbb-build ^
-DCMAKE_BUILD_TYPE=Release ^
-DCMAKE_INSTALL_PREFIX=%OPV_HOME_DIR%/one-tbb-install ^
-DCMAKE_TOOLCHAIN_FILE=%CURRENT_CMAKE_TOOLCHAIN_FILE% ^
-DANDROID_ABI=%CURRENT_ANDROID_ABI% ^
-DANDROID_PLATFORM=%CURRENT_ANDROID_PLATFORM% ^
-DANDROID_STL=%CURRENT_ANDROID_STL% ^
-DTBB_TEST=OFF ^
-DCMAKE_SHARED_LINKER_FLAGS="-Wl,--undefined-version". 

followed by 

# Build OneTBB™ project 
cmake --build $OPV_HOME_DIR/one-tbb-build --parallel
# Install OneTBB™ project 
cmake --install $OPV_HOME_DIR/one-tbb-build

 Hope this will generate the jar and libinference_java_api.so

Regards,

Madhini
