ndk-build failed to build PocketSphinxAndroidDemo project - android-ndk

Question

I am trying to use "android-ndk-r5b" to build PocketSphinx for Android.
I downloaded PocketSphinxAndroidDemo project from "https://cmusphinx.svn.sourceforge.net/svnroot/cmusphinx/trunk/PocketSphinxAndroidDemo" alone with "pocketsphinx" and "sphinxbase" projects.
I am on Windows 7 and using Cygwin to run "ndk-build" the problem is all static libraries (.a file) are generated but unable to create the .so file due to the following reference error:
$ /cygdrive/c/android-ndk-r5b/ndk-build

All the header file paths are specified. No problem to create static libraries but has problem to link static libraries to create shared library.
Here is my "Android.mk" file:

# You MUST change this to the absolute path of the directory containing
# sphinxbase and pocketsphinx source code.

Thank you in advance for any suggestions!

Answer 1

Reverse your LOCAL_STATIC_LIBRARIES Sequence is ok

Answer 2

To expand on user642960's response, I changed the LOCAL_STATIC_LIBRARIES line within Android.mk to:
LOCAL_STATIC_LIBRARIES := pocketsphinx sphinxlm sphinxfeat sphinxfe sphinxutil
After doing so, the errors that the submitter is describing went away for me. I also upgraded NDK, but that didn't seem to fix things on its own.
