Building audio processing Little Endian SDK with NDK

Question

I am trying to use ndk-build to use native code for audio processing from Little Endian in an Android application (I don't have JNI yet).

When I executed ndk-build in jni dir I got ($USER_PATH is path to directory on my computer):

Android NDK: WARNING: Rebuilding libc++ libraries from sources!     Android NDK: You might want to use $NDK/build/tools/build-cxx-stl.sh --stl=libc++     Android NDK: in order to build prebuilt versions to speed up your builds!     Android NDK: ERROR:$USER_PATH/android-ndk-r10/sources/android/compiler-rt/Android.mk:compiler_rt_shared: LOCAL_SRC_FILES points to a missing file     Android NDK: $USER_PATH/Android/android-ndk-r10/sources/android/compiler-rt/libs/armeabi/libcompiler_rt_shared.so exists  or that its path is correct    $USER_PATH/android-ndk-r10/build/core/prebuilt-library.mk:45: *** Android NDK: Aborting    .  Stop. 

I saw that is because of PREBUILT_STATIC_LIBRARY which points to missing files.

How can I solve this?

Directory structure:

There are .mk files:

Android.mk

Try this a new solution by Google for audio application.
