Compiling the OpenCV library for stitching images using the NDK android in cygwin causes an error while creating libutils.so

Question

I use OpenCV-2.4.9 sdk and the OpenCV stitching library to create a panoramic image that compile and create .so files in the libs folder inside the application

• I use cygwin for windows to compile the jni directory from the project. it gives an error as shown in the figure below:

• tried on windows 7.8 (x86, x64) but it gives the same error
• successfully compiled other OpenCV example libraries, but this file was not successfully compiled.

Does anyone know what causes this error?
