我正在尝试构建一个随NDK提供的示例Android应用程序,其中包含以下Android.mk文件：

LOCAL_PATH := $(call my-dir)
MY_PATH := $(LOCAL_PATH)
include $(call all-subdir-makefiles)

include $(CLEAR_VARS)

LOCAL_PATH := $(MY_PATH)

LOCAL_MODULE    := native-activity
LOCAL_SRC_FILES := main.c
LOCAL_LDLIBS    := -llog -landroid -lEGL -lGLESv1_CM
LOCAL_STATIC_LIBRARIES := android_native_app_glue

include $(BUILD_SHARED_LIBRARY)

$(call import-module,android/native_app_glue)

当我构建我的项目时,我得到以下错误：

**** Build of configuration Default for project NativeActivity ****

/Users/Jono/Documents/Development/Android Development/android-ndk-r9c/ndk-build all 
usage: dirname path
make: /Users/Jono/build/core/build-local.mk: No such file or directory
make: *** No rule to make target `/Users/Jono/build/core/build-local.mk'.  Stop.

**** Build Finished ****

问题是它在我的根目录中寻找构建文件,但我不确定它在做什么,它在寻找什么文件,它应该在哪里查找,然后我应该做些什么来修复它.
