在之前的一系列博客中使用 lib7zr.so 动态库处理压缩文件 , 本篇博客中使用静态库处理压缩文件 , 仅做参考 ;






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

静态库 lib7zr.a ;


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

【Android 安装包优化】使用 lib7zr.a 静态库处理压缩文件 ( 交叉编译 lib7zr.a 静态库 | 安卓工程导入静态库 | 配置 CMakeLists.txt 构建脚本 )(一)



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 ;

【Android 安装包优化】使用 lib7zr.a 静态库处理压缩文件 ( 交叉编译 lib7zr.a 静态库 | 安卓工程导入静态库 | 配置 CMakeLists.txt 构建脚本 )(一)



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=1
    adb push ./libs/armeabi/7zr /data/app/
    adb push ./libs/armeabi/gdbserver /data/app/
    adb shell chmod 777 /data/app/7zr
    adb shell chmod 777 /data/app/gdbserver
    adb forward tcp:1234: tcp:1234
    adb 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 , 不能用于静态库编译 ;


# 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
# 如果编译静态库 , 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_STATIC_LIBRARY)


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 :


#

#
# WARNING : file generated by generate.py
#
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)

# 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
# 如果编译静态库, 编译结果是 lib7zr.a
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

三、交叉编译 lib7zr.a 静态库


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
