QNN EP is not initialized in v1.21.0

[ctosec]

Hello

I'm trying to port onnx model to SM8650.

Below is build command that I'm using.
./build.sh --android --config Release --parallel --use_qnn static_lib --qnn_home=/home2/jerry.kang/QNN/qairt/2.26.2.240911/ --android_sdk_path=/opt/android-sdk --android_ndk_path=/opt/android-ndk-r27c --android_abi arm64-v8a --android_api=34 --cmake_generator Ninja --build_dir build/Android --skip_tests --cmake_extra_defines=-Wno-error=all

with this command I can get onnxruntime.so file because it is static_lib option.
But when I run model I got below messages.

[V:onnxruntime:Default, qnn_backend_manager.cc:265 QnnLogging] QnnDsp QnnLog_create started.

As far as I know libQnnHtpV75Stub.so is created when -build_shared_lib and without --android option.

Can you please help me to resolve this issue?

libQnnHtpV75Stub.so is present in the QNN SDK provided by Qualcomm. You will have to link it to libonnxruntime.so or your android native app while building the app to make it work.
