I'm following [this](http://kurup87.blogspot.ca/2012/03/android-ocr-tutorial-image-to-text.html) tutorial to compile [this](https://github.com/rmtheis/tess-two) fork of Tesseract (an optical character recognition package) for Android. I'm at the step where I use Cygwin to build the NDK for the Tesseract Android project. I'm getting the following error when invoking ndk-build (from the tess-two directory):

```
c:/android-ndk-r8b-windows/android-ndk-r8b/toolchains/arm-linux-androideabi-4.6/prebuilt/windows/bin/../lib/gcc/arm-linux-androideabi/4.6.x-google/../../../../arm-linux-androideabi/bin/ld.exe: cannot find ./obj/local/armeabi-v7a/libgnustl_static.a: Permission denied

```

What could be causing this error? On a side note, is there an easier way to get Tesseract up and running on Android?
