AOSP 源码下载与编译

Posted Dec 12, 2019 2019-12-12T02:31:44+08:00 by sleticalboy

本实验环境为 Ubuntu 18.04

准备环境

1、安装 openJDK8

1

sudo apt install openjdk-8-jdk openjdk-8-source openjdk-8-doc

2、如果编译 Android 6.0 以下的源码，需要安装 openjdk7（此安装源在 Ubuntu 18.04 已经被移除了，这里用 oracle jdk 7 代替）

1

# step 1： 下载 jdk7 https://download.oracle.com/otn/java/jdk/7u80-b15/jdk-7u80-linux-x64.tar.gz?AuthParam=1570605801_fcfbdb29eeacd52532bdd180633ab5f7
# step 2： 配置多版本 java/javac
# step 2.1： 先`安装`
sudo update-alternatives --install /usr/bin/java java /usr/lib/jvm/java-7-oraclejdk/bin/java 1082
sudo update-alternatives --install /usr/bin/javac javac /usr/lib/jvm/java-7-oraclejdk/bin/javac 1082
# step 2.2： 选择不同的版本
sudo update-alternatives --config java
sudo update-alternatives --config javac

3、安装 git 工具

  • 安装：sudp apt install git
  • 配置用户名和 email
    1
2

    git config --global user.name "username"
git config --global user.email "email"
  • 配置提交信息编辑器：git config --global core.editor=vim

4、安装 python2.7（repo 脚本是用 python2.7 版本编写的， 不能兼容 python3； 而 Ubuntu 18.04 自带 python3）

1

sudo apt install python2.7

5、安装源码管理脚本 repo

1

7
8

# step 1： 获取 repo 脚本
curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
# step 2： 添加可执行权限
chmod a+x ~/bin/repo
# step 3： 将 repo 脚本添加到可执行路径中
echo 'export PATH=/home/binli/bin:$PATH' >>~/.bashrc
# step 4： 刷新环境
source ~/.bashrc

源码下载

参考：清华大学开源软件镜像站 Android 镜像使用帮助

下载 repo 工具

mkdir ~/bin
PATH=~/bin:$PATH
curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
# or curl https://mirrors.tuna.tsinghua.edu.cn/git/git-repo -o ~/bin/repo
chmod a+x ~/bin/repo

初始化仓库

  • repo init -u https://mirrors.tuna.tsinghua.edu.cn/git/AOSP/platform/manifest
  • 指定 Android 版本：repo init -u https://mirrors.tuna.tsinghua.edu.cn/git/AOSP/platform/manifest -b android-4.0.1_r1

同步源码

  • repo sync

源码编译

安装编译源码所需的依赖

1、安装大部分依赖包

sudo apt install libx11-dev:i386 libreadline-dev:i386 libgl1-mesa-dev \
g++-multilib -y flex bison gperf build-essential libncurses5-dev:i386 tofrodos \
python-markdown libxml2-utils xsltproc zlib1g-dev:i386 dpkg-dev libsdl1.2-dev \
git gnupg flex bison gperf build-essential zip curl zlib1g-dev gcc-multilib \
g++-multilib libc6-dev-i386 lib32ncurses5-dev x11proto-core-dev libx11-dev \
libgl1-mesa-dev libxml2-utils xsltproc unzip m4 lib32z1-dev ccache

2、单独安装 libesd0-dev

  • 追加以下内容到 /etc/apt/source.list 文件（root 权限）
    1
2
3

    # for install libesd0-dev
deb http://us.archive.ubuntu.com/ubuntu/ xenial main universe    
# deb-src http://us.archive.ubuntu.com/ubuntu/ xenial main universe
  • 更新并安装
    1
2

    sudo apt update 
sudo apt install libesd0-dev

3、安装 python 依赖包 cropto

  • 首先安装 pip 包管理工具：sudo apt install python-pip
  • 使用 pip 安装 crypto 模块：pip install crypto
  • 验证是否安装成功

    python
Python 2.7.15+ (default, Oct  7 2019, 17:39:04) 
[GCC 7.4.0] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> from Crypto.Signature import PKCS1_v1_5
>>> 此处若无输出则说明安装成功

编译源码

1、设置环境变量：source build/envsetup.sh

2、选择编译目标

lunch 
You're building on Linux
Lunch menu... pick a combo:
    1. aosp_arm-eng
    2. aosp_arm64-eng
    3. aosp_mips-eng
    4. aosp_mips64-eng
    5. aosp_x86-eng
    6. aosp_x86_64-eng

    Which would you like? [aosp_arm-eng] 6

3、开始编译：make -j4

4、漫长的等待之后如有#### build completed successfully (03:21:10 (hh:mm:ss)) #### 则表明编译成功

烧写镜像

分支切换

问题总结

Ubuntu 18.04 编译 Android 9.0 源码

Ubuntu 18.04 编译 Android 6.0 源码

1、问题：flex-2.5.39: loadlocale.c:130: _nl_intern_locale_data: Assertioncnt < (sizeof (_nl_valu

方法一：

1
2

# 解决办法
export LC_ALL=C

方法二：（如果方法一无效再尝试方法二）

1
2

# 最好是重命名而不是删除
# rm prebuilts/misc/linux-x86/flex/flex-2.5.39
# 做一个软连接
ln -s /usr/bin/flex prebuilts/misc/linux-x86/flex/flex-2.5.39

2、recipe for target ‘out/host/linux-x86/obj/lib/libart.so’ failed function.sh: line 44: sendemail: command not found

  • 2.1 缺少 sendemail 软件包, 如果仍然报错尝试 2.2
1

sudo apt install sendemail
  • 2.2 尝试关闭 clang 编译器
