I use this cmd below:

cmake -B ./build -G Ninja -DCMAKE_TOOLCHAIN_FILE=$ANDROID_NDK_HOME/build/cmake/android.toolchain.cmake -DANDROID_ABI=x86_64 -S .
cmake --build ./build

Notice that this header file we tried to rename libvsomeip3-cfg.so TO libvsomeip_cfg.so but we got this:

dynamic_pointer_cast this issue where some objects return nullptr Created outside of the boundaries of the shared library. See below discuss for more details. https://github.com/android/ndk/issues/519 https://github.com/android/ndk/issues/533

Hi @007herelsp

Thanks very much for the info. I have carefully studied the discussions for all these, my current understanding is: The only approach for Android is linking the cfg library explicitly. Do I understand correctly?

I have tried some things like

• dlopen with DL_GLOBAL
• add a key function to configuration_plugin

None of the above worked.

ps: I personally do not like using dynamic_cast cross module boundaries, which leads to a dark place in the ABI spec. Maybe we should redesign the plugin system to rely on more stable interfaces.

Best regards,
