在使用ndk-build编译c时遇到了上述问题，没有生成so文件
/Users/qinan/android/android-ndk-r9/build/core/clear-vars.mk 这个路径是存在的，不知为什么会报No such file or directory的错误

Android.mk内容：
LOCAL_PATH:= $(call my-dir)


include $(CLEAR_VARS)

LOCAL_SRC_FILES:= jniTest_helloJni.c

LOCAL_MODULE:= jniTest_helloJni
LOCAL_MODULE_FILENAME:= libjniTest_helloJni
LOCAL_FORCE_STATIC_EXECUTABLE := true

#LOCAL_STATIC_LIBRARIES := libc

#LOCAL_CFLAGS += -Iinclude/dir -DSOMEFLAGS


include $(BUILD_SHARED_LIBRARY)

Application.mk内容:
APP_STL := gnustl_static


ndk-build脚本内容：
DIR="$( cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd )"
APP_ANDROID_ROOT="$DIR"
"$NDK_ROOT"/ndk-build -C "$APP_ANDROID_ROOT"
