标签：845 git OKAY sudo 3XL system dev repo 刷机
androidS 发布已经有一段时间了，作为一名搞机人，咱也不能落后，今天就来开盘 12 代码。
下载这个 S 代码前前后后搞了快一个月，哈哈我不愧是树懒本懒。唉，其实是中间遇到了不少问题，
环境都搞废了，还得重装系统，今天就来总结一下吧。
编译环境
1、Ubuntu16.04.5 系统
2、三星500G SSD EVO系列
3、内存8G，cpu 4核，I5(8年老本了凑合着用用)
4、二手 Pixel 3 XL一台
坑位集锦
1、磁盘大小
如果你是在虚拟机来盘这套代码的话，磁盘大小至少200G以上(血泪教训)，中间扩容了三次最终还是不够大
仅仅 repo 文件夹就有 70G 左右
磁盘空间一定要大，一定要大，一定要大
不是虚拟机的请忽略这步
2、Python 版本要求
这次下载 aosp 的 S 代码时，repo init 就出现了问题，提示要求 Python 版本 3.6 以上
在这也是费了好长时间才解决这个问题，具体可参考 Linux python升级
从官网下载最新版本 Python-3.9.8 解压，解压完成后先不要着急 make install
还有个小坑，会报
ModuleNotFoundError: No module named ‘_ctypes’ 这个错误
以及 ModuleNotFoundError: No module named ‘_ssl’ 这个错误
解决办法，执行如下两条指令
sudo apt-get install libssl-dev openssl
sudo apt-get install libffi-dev
成功后，再参考 python3虚拟环境中解决 ModuleNotFoundError: No module named ‘_ssl’
修改源码 vim Modules/Setup
取消 _socket socketmodule.c 和下面的 SLL 注释
然后执行 make install 安装重新配置环境变量。
3、HTTP SSL 证书问题
执行 git config --global http.sslverify false 关闭
cczheng@ubantu:~/google$ cd Android12/
cczheng@ubantu:~/google/Android12$ export REPO_URL='https://gerrit-googlesource.proxy.ustclug.org/git-repo'
cczheng@ubantu:~/google/Android12$ repo init -u git://mirrors.ustc.edu.cn/aosp/platform/manifest -b android-12.0.0_r3

Downloading Repo source from https://gerrit-googlesource.proxy.ustclug.org/git-repo

If you want to change this, please re-run 'repo init' with --config-name
repo has been initialized in /home/cczheng/google/Android12
做完这些步骤后，repo init 终于可以成功了。
准备工作
1、设置 git 账户
git config --global user.email "xxxxxxx@gmail.com"
git config --global user.name "xxxxx"
2、配置PATH环境变量
mkdir ~/bin
echo "PATH=~/bin:\$PATH" >> ~/.bashrc
source ~/.bashrc
3、安装 curl 库，并设置权限
sudo apt-get install curl
curl -sSL 'https://gerrit-googlesource.proxy.ustclug.org/git-repo/+/master/repo?format=TEXT' |base64 -d > ~/bin/repo
chmod a+x ~/bin/repo
下载源码
1、建立工作目录
mkdir Android12
cd Android12
2、添加科大镜像源
export REPO_URL='https://gerrit-googlesource.proxy.ustclug.org/git-repo'
3、初始化仓库，并指定要下载android版本
repo init -u git://mirrors.ustc.edu.cn/aosp/platform/manifest -b android-12.0.0_r3
4、同步源码
repo sync -j4
编译源码
1、安装 openjdk8
sudo add-apt-repository ppa:openjdk-r/ppa
sudo apt-get update
sudo apt-get install openjdk-8-jdk
如果电脑里面存在多个java 版本，则通过如下命令选择openjdk-8即可
sudo update-alternative --config java
sudo update-alternative --config javac
2、安装依赖库
sudo apt-get install libx11-dev:i386 libreadline6-dev:i386 libgl1-mesa-dev g++-multilib
sudo apt-get install -y git flex bison gperf build-essential libncurses5-dev:i386
sudo apt-get install tofrodos python-markdown libxml2-utils xsltproc zlib1g-dev:i386
sudo apt-get install dpkg-dev libsdl1.2-dev libesd0-dev
sudo apt-get install git-core gnupg flex bison gperf build-essential
sudo apt-get install zip curl zlib1g-dev gcc-multilib g++-multilib
sudo apt-get install libc6-dev-i386
sudo apt-get install lib32ncurses5-dev x11proto-core-dev libx11-dev
sudo apt-get install libgl1-mesa-dev libxml2-utils xsltproc unzip m4
sudo apt-get install lib32z-dev ccache
sudo apt-get install libssl-dev
3、下载对应闭源驱动文件合入源码
可以到下面的地址下载 pixel 对应驱动文件或者完整 rom 包
4、开始编译
通过 lscpu 命令查看当前cpu的详细信息
执行命令
source build/envsetup.sh
lunch 25 (aosp_crosshatch-userdebug 版本)
make -j8
lunch 根据上面cpu的类型，make -j cpu核数*2
编译完成23小时，哈哈哈哈哈哈
刷机，参考官方包自己写个刷机脚本，将你编译后out目录下得到的如下文件
copy出来，全部添加到压缩文件 aosp12.zip
然后依次执行
adb reboot fastboot
fastboot -w update .\aosp12.zip
fastboot reboot
PS H:\rom12\aosp12> adb reboot fastboot
PS H:\rom12\aosp12> fastboot -w update .\aosp12.zip
