android ndk

Question

当我在cygwin中编译会出现obj/local/armeabi/objs/jnindk/jnindk.o.d:1: *** 目标模式不含有“%”。 停止。
我的mk是这么写的：
LOCALPATH := $(call my-dir)include $(CLEAR_VARS)LOCAL_MODULE := jnindk
LOCAL_SRC_FILES := jnindk.cinclude $(BUILD_SHARED_LIBRARY)

我编译过后，出现以下错误，是so没有导入呢，还是其他什么原因造成的？

楼主问题是因为Android.mk中少了这句：
LOCAL_PATH := $(call my-dir)
