I am trying to compile my C code using Android NDK. I downloaded and installed, as suggested on the Android NDK Page , and tried to compile as prescribed, but it seems to have some problems, and I don’t know. It seems like it doesn’t know what it is.

 *** Command Line compile code **
C:\cygwin\android-ndk-r7c>ndk-build -C C:\Users\BoosterJack\workspace\workAndroid
    Android NDK: Trying to define local module 'stdc++' in C:/cygwin/android-ndk-r7c/sources/cxx-stl/system/Android.mk.
    Android NDK: But this module was already defined by C:/cygwin/android-ndk-r7c/sources/cxx-stl/system/Android.mk.
    make: Entering directory `C:/Users/BoosterJack/workspace/workAndroid'
    C:/cygwin/android-ndk-r7c/build/core/build-module.mk:34: *** Android NDK: Aborting.    .  Stop.
    make: Leaving directory `C:/Users/BoosterJack/workspace/workAndroid'

My make file is also simple. Any help would be greatly appreciated.

# Include makefiles here.
include $(LOCAL_PATH)/Android.mk 

   LOCAL_PATH := $(call my-dir)

   include $(CLEAR_VARS)

   LOCAL_MODULE    := NativeLibjni
   LOCAL_SRC_FILES := NativeLib.c

   include $(BUILD_SHARED_LIBRARY)

UPDATE

When I delete a line from my makefile, include $ (LOCAL_PATH) /Android.mk, I get the correct output, which

C:\Users\BoosterJack>ndk-build -C C:\Users\BoosterJack\workspace\workAndroid
make: Entering directory `C:/Users/BoosterJack/workspace/workAndroid'
"Compile thumb : NativeLibjni <= NativeLib.c
SharedLibrary  : libNativeLibjni.so
