Problems trying to build PocketSphinxAndroidDemo using NDK

I am trying to compile PocketSphinxAndroidDemo, which provides an example implementation of the CMU pocketsphinx speech recognizer on Android. I first received an error similar to the discussion here. After executing ndk-build, I got this error:

Gdbserver      : [arm-linux-androideabi-4.4.3] libs/armeabi/gdbserver
Gdbsetup       : libs/armeabi/gdb.setup
Compile thumb  : pocketsphinx_jni <= pocketsphinx_wrap.c

make: *** [/home/nick/workspace/android/PocketSphinxDemo/obj/local/armeabi/objs-debug/pocketsphinx_jni/pocketsphinx_wrap.o] Error 1

I tried the recommendation of rebuilding the sphinxbase and pocketsphinx libraries and rebuilding with ndk-build -B, but that didn't work. I then modified the jni/pocketsphinx.i swig file to change the include for err.h:

#include <pocketsphinx.h>
//#include <sphinxbase/err.h>
#include <err.h>

Did anyone that tried to compile PocketSphinxAndroidDemo ever encounter this problem? My edit seemed to allow me to get further in my compilation, but now I'm getting assembly-related errors:

Again, does anyone know how to resolve this problem? I haven't seen any other developers complaining of this problem, so I'm hesitant to go further. Thanks for your help.

Apparently, some of the sources still needed to be marked for ARM compilation. I modified the following section of Android.mk to set cmn.c and lda.c to compile with ARM.

include $(CLEAR_VARS)
LOCAL_C_INCLUDES := $(SPHINX_PATH)/sphinxbase/include/android $(SPHINX_PATH)/sphinxbase/include
LOCAL_CFLAGS += -DHAVE_CONFIG_H
LOCAL_CFLAGS += -DANDROID_NDK

LOCAL_PATH := $(SPHINX_PATH)/sphinxbase/src/libsphinxbase/feat
LOCAL_MODULE := sphinxfeat

LOCAL_SRC_FILES := \
    agc.c \
    cmn.c.arm \
    cmn_prior.c.arm \
    feat.c \
    lda.c.arm

I am still wondering if anyone else had to do this to get their code to compile successfully.

Edit file jni/Android.mk

Change Line 162 :

LOCAL_STATIC_LIBRARIES := sphinxutil sphinxfe sphinxfeat sphinxlm pocketsphinx

to :

LOCAL_STATIC_LIBRARIES := pocketsphinx sphinxlm sphinxfeat sphinxfe sphinxutil
