ndk-build：-如何从Windows中调用$ {abspath $ {LOCAL_PATH））获取确切路径？

Question

I am doing a sample native project. I have two make files one is Android1.mk and another one is Android2.mk. The second one is placed outside the project folder.My android studio project is located at

H:/Ndk_Dev/Demo

Android1.mk located at

H:/Ndk_Dev/Demo/app/src/main/jni

and Android2.mk is located at

H:/Ndk_Dev/externalJni

Android1.mk contains.

LOCAL_PATH := $(call my-dir)
MY_ROOT_PATH := $(abspath $(LOCAL_PATH)/../../../../../)
.......
.......
.......
include $(MY_ROOT_PATH)/externalJni/Android2.mk

but while compiling, the path i got was

LOCAL_PATH    -------> H:/Ndk_Dev/Demo/app/src/main/jni
MY_ROOT_PATH  -------> H:/Ndk_Dev/Demo/app/src/main/H:/Ndk_Dev

So it points to an invalid path for Android2.mk which was

H:/Ndk_Dev/Demo/app/src/main/H:/Ndk_Dev/externalJni/Android2.mk

On my understanding the MY_ROOT_PATH should be H:/Ndk_Dev

Have anybody know any issue in calling $(abspath) on Windows.

Answer 1

You should just call as following

MY_ROOT_PATH := $(abspath ../../../../../)

It works for me.
