一、修改 7zr 交叉编译脚本 Android.mk

之前的博客【Android 安装包优化】p7zip 源码交叉编译 Android 平台可执行程序 ( 下载 p7zip 源码 | 交叉编译 Android 中使用 7z 可执行程序 ) 中 , 下载并编译了 p7zip 开源项目源码 , 交叉编译出了可以在 Android 平台执行的可执行文件 ;

D:\develop\7zip\p7zip_16.02\CPP\ANDROID\7zr 目录下是 7zr 项目的构建脚本 Android.mk 和 Application.mk , 主要使用该构建脚本交叉编译出

可执行文件 7zr
动态库 lib7zr.so ;

进入 7zr 目录下 , 有一个 jni 目录和 makefile 文件 ,

jni 目录中是 Android.mk 和 Application.mk 两个构建脚本 , 可以使用 ndk-build 进行编译 ;

打开该 makefile 文件 , 该文件最后几行代码给出了相关操作方法 ;

# FIXME
debug:cd jni ; ndk-build NDK_DEBUG=1adb push ./libs/armeabi/7zr /data/app/adb push ./libs/armeabi/gdbserver /data/app/adb shell chmod 777 /data/app/7zradb shell chmod 777 /data/app/gdbserveradb forward tcp:1234: tcp:1234adb shell  /data/app/gdbserver :1234 /data/app/7zr

进入 D:\develop\7zip\p7zip_16.02\CPP\ANDROID\7zr\jni 目录 , 执行 ndk-build 命令 , 进行交叉编译 ;

修改 Application.mk 构建脚本 :

APP_ABI := armeabi-v7a arm64-v8a x86 x86_64
APP_PLATFORM := android-8

注释可执行文件的编译选项 : -fPIE 指的是生成与地址无关的可执行文件 , 该选项只能应用于可执行文件 , 不能用于动态库编译 ;

# Needed since ANDROID 5, these programs run on android-16 (Android 4.1+)
# -fPIE 指的是生成与地址无关的可执行文件 , 该选项只能应用于可执行文件 ,
# 不能用于动态库编译
# 如果编译动态库 , 需要注释掉下面两个配置
# 如果编译可执行文件 , 可以保留下面两个配置
#LOCAL_CFLAGS += -fPIE
#LOCAL_LDFLAGS += -fPIE -pie

设置 Android.mk 构建脚本的编译结果 :

include $(BUILD_EXECUTABLE)

include $(BUILD_EXECUTABLE) 配置表示生成可执行文件 ;
include $(BUILD_SHARED_LIBRARY) 配置表示生成 .so 动态库 ;
include $(BUILD_STATIC_LIBRARY) 配置表示生成 .a 静态库 ;

二、完整的 7zr 交叉编译脚本 Android.mk

修改完成的构建脚本 :

#
# build 7zr for armeabi and armeabi-v7a CPU
#
# WARNING : file generated by generate.py
#LOCAL_PATH := $(call my-dir)include $(CLEAR_VARS)# 编译模块
# 如果编译可执行文件, 编译结果是 7zr
# 如果编译动态库, 编译结果是 lib7zr.so
LOCAL_MODULE := 7zr# 设置编译器参数
# -I 指定头文件引入目录 , 会引入后面目录中所有的 .h 头文件
LOCAL_CFLAGS := -DANDROID_NDK  -fexceptions \-DNDEBUG -D_REENTRANT -DENV_UNIX \-DBREAK_HANDLER -D_NO_CRYPTO \-DUNICODE -D_UNICODE -DUNIX_USE_WIN_FILE \-I../../../7zip/Archive \-I../../../7zip/Archive/7z \-I../../../7zip/Archive/BZip2 \-I../../../7zip/Archive/Common \-I../../../7zip/Archive/GZip \-I../../../7zip/Archive/Cab \-I../../../7zip/Archive/Lzma \-I../../../7zip/Archive/Tar \-I../../../7zip/Archive/Zip \-I../../../7zip/Archive/Split \-I../../../7zip/Archive/Z \-I../../../7zip/Compress \-I../../../7zip/Crypto \-I../../../7zip/UI/Console \-I../../../7zip/UI/Common \-I../../../Windows \-I../../../Common \-I../../../7zip/Common \-I../../../../C \

三、交叉编译 lib7zr.so 动态库

使用最低版本的 NDK 进行编译 , 使用高版本 NDK 编译各种报错 ;

使用 16.1.4479499 版本的 NDK 进行编译 :

>D:\001_Programs\001_Android\002_Sdk\Sdk\ndk\16.1.4479499\ndk-build.cmd

进入 D:\develop\7zip\p7zip_16.02\CPP\ANDROID\7zr\jni 目录 , 执行如下命令 :

D:\001_Programs\001_Android\002_Sdk\Sdk\ndk\16.1.4479499\ndk-build.cmd

编译要很长时间 , 输出如下结果后 ,

最终在 D:\develop\7zip\p7zip_16.02\CPP\ANDROID\7zr\libs\armeabi-v7a 目录下 , 生成了可执行的 7zr 程序 ;

总共生成了 444 种 CPU 架构的可执行文件 ;

编译过程中其它生成文件如下图 :

编译时遇到的错误 :

【错误记录】Android Studio 导入外部 so 动态库报错 ( java.lang.UnsatisfiedLinkError | 指定 APK 打包动态库的 CPU 架构 )
【错误记录】p7zip 交叉编译 Android 版本 NDK 报错 ( error: case value evaluates to -2 , which cannot be narrowed )
