给 Xiaomi 6 编译 LineageOS 过程小记

发表于 更新于 分类于 阅读次数： 4651

2023年9月1日: 更新了大伙儿常遇到的 breakfast 命令失败的问题处理办法, 可以参考一下.

最近给手头的 Xiaomi 6 刷了 LneageOS, 体验了一把 Android 13, 挺香的! 但是这个系统有那么一丢丢水土不服, 于是决定自己来改改然后编译一个出来玩玩.

主机描述

  • CPU >= 4C
  • MEM >= 16G
  • DISK >= 200G
  • NET >= 100M
  • OS >= Debian 11/12

环境准备

安装 repo 工具

下载&安装:

mkdir ~/bin
curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
chmod a+x ~/bin/repo

若无法下载可镜像下载: curl https://mirrors.tuna.tsinghua.edu.cn/git/git-repo > ~/bin/repo

更新环境变量(视情况操作, 可能已经有配置了):

cat >> ~/.profile <<EOF
# set PATH so it includes user's private bin if it exists
if [ -d "$HOME/bin" ] ; then
    PATH="$HOME/bin:$PATH"
fi
EOF
source ~/.profile

安装平台工具

sudo apt install android-sdk-platform-tools android-sdk-platform-tools-common
sudo usermod -aG plugdev $LOGNAME

安装必要软件

sudo apt install python3 \
bc bison build-essential ccache curl flex g++-multilib gcc-multilib git git-lfs gnupg gperf imagemagick \
lib32ncurses5-dev lib32readline-dev lib32z1-dev libelf-dev liblz4-tool libncurses5 libncurses5-dev \
libsdl1.2-dev libssl-dev libxml2 libxml2-utils lzop pngcrush rsync \
schedtool squashfs-tools xsltproc \
zip zlib1g-dev
sudo ln -s /bin/python3 /bin/python

软件列表请参考: https://wiki.lineageos.org/devices/sagit/build#install-the-build-packages

配置 git 用户信息

配置基本信息:

git config --global user.email "you@example.com"
git config --global user.name "Your Name"

指定 LineageOS 仓库镜像(清华大学镜像源):

cat >> ~/.gitconfig <<EOF
[url "https://mirrors.tuna.tsinghua.edu.cn/git/git-repo"]
    insteadof = https://gerrit.googlesource.com/git-repo
[url "https://mirrors.tuna.tsinghua.edu.cn/git/AOSP/"]
    insteadof = https://android.googlesource.com/
[url "https://mirrors.tuna.tsinghua.edu.cn/git/lineageOS/"]
    insteadof = https://review.lineageos.org/
[url "https://mirrors.tuna.tsinghua.edu.cn/git/lineageOS/LineageOS/"]
    insteadof = https://github.com/LineageOS/
EOF

配置 ccache 加速

cat >> ~/.bashrc <<EOF
export USE_CCACHE=1
export CCACHE_EXEC=/usr/bin/ccache
export CCACHE_DIR=~/.cache/ccache
EOF

ccache -M 50G
ccache -o compression=true
mkdir -p ~/.cache/ccache/

同步代码

mkdir -p ~/projects/android_lineage
cd ~/projects/android_lineage
repo init -u https://github.com/LineageOS/android.git -b lineage-21.0 --git-lfs
repo sync -c -d

编译

初始化编译环境

source build/envsetup.sh
breakfast sagit

这个环节会根据设备型号拉取对应的内核仓库, 建议使用镜像仓库加速.

对于 Xiaomi 6, 这个环节第一次执行会因为没有导入二进制文件而失败, 请参考踩坑记录.
如果碰到 Can not locate config makefile for product "lineage_sagit". 的问题也请参考踩坑记录.

导入厂商二进制文件

厂商代码是不开源的, 需要引用现有的二进制; 可以从设备提取, 也可以从现有的 ROM 包里面提取, 二选一即可.

  • 从设备提取
cd ~/projects/android_lineage/device/xiaomi/sagit/
sudo ./extract-files.sh

这个环节需要开启 Xiaomi 6 设备的 开发者选项的调试模式 , 并连接至编译主机. 然后执行上述命令.

  • 从现有 ROM 包里面提取
mkdir -p ~/temp/lineage_system_dump/
cd ~/temp/lineage_system_dump/

unzip path/to/lineage-*.zip \
system.transfer.list system.new.dat* \
vendor.transfer.list vendor.new.dat*

sudo apt-get install brotli
brotli --decompress --output=system.new.dat system.new.dat.br
brotli --decompress --output=vendor.new.dat vendor.new.dat.br

git clone https://github.com/xpirt/sdat2img
python sdat2img/sdat2img.py system.transfer.list system.new.dat system.img
python sdat2img/sdat2img.py vendor.transfer.list vendor.new.dat vendor.img

mkdir system/
sudo mount system.img system/
# sudo rm -rf system/vendor
# sudo mkdir system/vendor
sudo mount vendor.img system/vendor/

cd ~/projects/android_lineage/device/xiaomi/sagit/
sudo ./extract-files.sh ~/temp/lineage_system_dump/

sudo umount ~/temp/lineage_system_dump/system/vendor
sudo umount ~/temp/lineage_system_dump/system
# rm -rf ~/temp/lineage_system_dump/

完成之后重新执行 breakfast sagit 初始化环境.

启动编译

croot
brunch sagit

踩坑记录

git lfs 同步失败

错误示例

由于上面拉取代码是配置了镜像仓库的, 但是镜像仓库中 git lfs 的部分文件不全, 导致同步失败.

拉取代码偶现无法解析主机名

错误示例

略

解决办法

  • 避免使用过多的线程, 宽带带宽不够的情况下某些线程抢不到资源, 导致连接失败;
  • 检查网络连接质量, 必要时可以考虑科学上网; 
    # http
git config --global http.proxy 'http://192.168.8.12:7890'
git config --global https.proxy 'http://192.168.8.12:7890'
# socks
git config --global http.proxy 'socks5://192.168.8.12:7890'
git config --global https.proxy 'socks5://192.168.8.12:7890'
# cancel
git config --global --unset http.proxy
git config --global --unset https.proxy

解决办法

取消 https://review.lineageos.org/ 镜像配置, 删除出错的源码目录重新同步. 使用国外服务器建议错峰访问, 晚上比白天慢很多.

rm -rf \

** Don't have a product spec for: 'lineage_sagit'
** Do you have the right repo manifest?

这是我新硬盘重新拉取代码后出现的问题, 第一次搭建环境的时候并没有出现, 折腾了很久. 最终通过看源码的方式定位原来是访问不到 Github 的文件服务器(刚好我上次同步代码的时候可以访问, 这个问题出现的频次挺高的, 我发了博客之后好几个人找我说了这个问题, 当时是不知所云, 现在明白了~).
LineageOS 源码在第一次初始化某个产品到时候, 会去 Github 上检索对应的配置便于拉取对于的代码仓库, 这个过程是通过访问 Github 的接口来实现的, 出现这个错误就是访问不到 Github 的文件服务器了.

解决办法

在文件 vendor/lineage/build/tools/roomservice.py 中作如下修改:

diff --git a/build/tools/roomservice.py b/build/tools/roomservice.py
index c723f921..196617d1 100755
--- a/build/tools/roomservice.py

就是给访问 Github 的请求加上代理服务器即可. 也可以尝试给 shell 环境加代理试试, 我这不想污染环境就没尝试了.

解决办法

IMPORTANT: Some devices require a vendor directory to be populated before breakfast will succeed. If you receive an error here about vendor makefiles, jump down to Extract proprietary blobs. The first portion of breakfast should have succeeded, and after completing you can rerun breakfast

某些设备需要填充供应商目录，然后才能成功 breakfast。需要先执行 导入厂商二进制文件 步骤然后再 breakfast。

执行 extract-files.sh 找不到文件
