Android-ndk 잘못된 명령 생성

Question

android ndk-build에 공유 라이브러리를 중간체/ndkbuild 폴더에 복사하지 못했습니다. 나는이 같은 Android.mk 내 모듈을 만들었습니다

Android.mk

을

LOCAL_PATH := $(call my-dir) 
include $(CLEAR_VARS) 
EXT_LIB_ROOT := $(LOCAL_PATH)/../prebuilt/dcmtk 

LOCAL_MODULE := ofstd 
LOCAL_SRC_FILES := $(EXT_LIB_ROOT)/ofstd/lib/$(TARGET_ARCH_ABI)/libofstd.so 
LOCAL_EXPORT_C_INCLUDES := $(EXT_LIB_ROOT)/ofstd/include 
include $(PREBUILT_SHARED_LIBRARY) 

include $(CLEAR_VARS) 
LOCAL_MODULE := oflog 
LOCAL_SRC_FILES := $(EXT_LIB_ROOT)/oflog/lib/$(TARGET_ARCH_ABI)/liboflog.so 
LOCAL_EXPORT_C_INCLUDES := $(EXT_LIB_ROOT)/oflog/include 
LOCAL_SHARED_LIBRARIES := ofstd 
include $(PREBUILT_SHARED_LIBRARY) 

그것은 구축하고 생성 된 명령은 : 지금

D:\android-sdk\ndk-bundle\\build\ndk-build.cmd NDK_PROJECT_PATH=null APP_BUILD_SCRIPT=C:\dev\trunk\myApp\app\Android.mk NDK_APPLICATION_MK=C:\dev\trunk\myApp\app\Application.mk APP_ABI=x86 NDK_ALL_ABIS=x86 NDK_DEBUG=1 APP_PLATFORM=android-21 NDK_OUT=C:/dev/trunk/myApp/app/build/intermediates/ndkBuild/debug/obj NDK_LIBS_OUT=C:\dev\trunk\myApp\app\build\intermediates\ndkBuild\debug\lib APP_SHORT_COMMANDS=false LOCAL_SHORT_COMMANDS=false -B -n 

이 로그의 출력이됩니다 :

불행히도 파일이 복사되거나 생성되지 않습니다. 명령 줄에서 동일한 명령을 실행하면 결과가 동일합니다. 그러나 명령 끝에서 -n 플래그를 건너 뛰면 명령이 복사되는 파일과 함께 성공적으로 완료됩니다. 그래서, 내 질문에 어떻게 그 -n 생략하고 그 플래그의 목적은 무엇입니까? 최신 stable ndk 릴리스를 사용하고 있습니다.

Answer 1

1. 프로젝트 폴더의 local.properties 파일에서 ndk 경로를 확인하십시오. Makefile을 빌드하기위한 ndk-bundle 경로를 보여줍니다. Gradle을 파일에

   ndk.dir=/Users/../Library/Android/sdk/ndk-bundle 
   

2. 확인 빌드 스크립트.

   sourceSets.main { 
       jni.srcDirs = [] 
       jniLibs.srcDir 'src/main/libs' 
   } 
   

   을 그리고 이것은 NDK 구축을위한 메이크 파일의 경로를 보여줍니다 :이 스크립트는 공유 libs와이 위치 할 위치를 보여줍니다

   externalNativeBuild { 
       ndkBuild { 
        path 'src/main/jni/Android.mk' 
       } 
   }
