android-ndk build cannot link boost system

I am trying to build sphinxbase library but it keeps giving following error:

C:/android-ndk-r8e/toolchains/arm-linux-androideabi-4.6/prebuilt/windows-x86_64/bin/../lib/gcc/arm-linux-androideabi/4.6/../../../../arm-linux-androideabi/bin/ld.exe: ./obj/local/armeabi/objs/base/__/__/__/__/__/src/libsphinxbase/util/SingletonLogMath.o: in function boost::thread_exception::thread_exception(int, char const*):C:\sdk/include/boost/thread/exceptions.hpp:51: error: undefined reference to 'boost::system::system_category()'

I searched over the internet and all I can found is that I should add boost-system library, also they says that it is important to use include the dependencies in the correct order. But I don't know what is the correct order.

Here is the part of android.mk file that might be important.

include $(CLEAR_VARS)
LOCAL_MODULE := boost_thread
LOCAL_SRC_FILES := lib/libboost_thread_pthread-gcc-mt-1_54.a
include $(PREBUILT_STATIC_LIBRARY)

include $(CLEAR_VARS)
LOCAL_MODULE := boost_system
LOCAL_SRC_FILES := lib/libboost_system-gcc-mt-1_54.a
include $(PREBUILT_STATIC_LIBRARY)

LOCAL_PATH := $(MY_LOCAL_PATH)

include $(CLEAR_VARS)

LOCAL_C_INCLUDES := $(LOCAL_PATH)/../../../../../src/libsphinxbase/fe $(LOCAL_PATH)/../../../../../src/libsphinxbase/fe $(LOCAL_PATH)/../../../../../include/android $(LOCAL_PATH)/../../../../../include $(SDK)/include
LOCAL_CFLAGS += -DHAVE_CONFIG_H
LOCAL_CPPFLAGS += -fexceptions -frtti
LOCAL_ARM_MODE := arm

...sources...

LOCAL_STATIC_LIBRARIES := boost_system, boost_thread

What should be the right order?

LOCAL_STATIC_LIBRARIES := boost_system, boost_thread

you should remove the ','

LOCAL_STATIC_LIBRARIES := boost_system boost_thread
