ubuntu14.04 编译 lineageos 14.1 for hammerhead

1 环境配置

1.1 切换apt源

切换apt源为阿里源，加快依赖包安装速度。 

sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak
sudo vim /etc/apt/sources.list
sudo apt-get update

将sources.list中默认源全部删除，使用如下所示的阿里源。 

deb http://mirrors.aliyun.com/ubuntu/ trusty main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ trusty-security main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ trusty-updates main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ trusty-proposed main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ trusty-backports main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ trusty main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ trusty-security main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ trusty-updates main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ trusty-proposed main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ trusty-backports main restricted universe multiverse

1.2 安装JDK8

lineageos 14.1使用android 7.1作为底版本，编译环境需要jdk8.

  • LineageOS 16.0: OpenJDK 1.9 (included by default)
  • LineageOS 14.1-15.1: OpenJDK 1.8 (install openjdk-8-jdk)
  • LineageOS 11.0-13.0: OpenJDK 1.7 (install openjdk-7-jdk)
sudo add-apt-repository ppa:openjdk-r/ppa
sudo apt-get update
sudo apt-get install openjdk-8-jdk
sudo update-alternatives --config java
sudo update-alternatives --config javac

执行java -version命令查看版本是否安装成功。

1.3 安装依赖包

sudo apt-get install bc bison build-essential ccache curl flex g++-multilib gcc-multilib git gnupg gperf imagemagick lib32ncurses5-dev lib32readline-dev lib32z1-dev liblz4-tool libncurses5-dev libsdl1.2-dev libssl-dev libwxgtk2.8-dev libxml2 libxml2-utils lzop pngcrush rsync schedtool squashfs-tools xsltproc zip zlib1g-dev

如果是ubuntu 16之后的版本，libwxgtk2.8-dev改为libwxgtk3.0-dev。

2 下载源码

2.1 下载repo

curl https://mirrors.tuna.tsinghua.edu.cn/git/git-repo -o repo
chmod +x repo

repo的运行过程中会尝试访问官方的git源更新自己，如果想使用tuna的镜像源进行更新，可以将如下内容复制到你的~/.bashrc里，然后重启终端。 

export REPO_URL='https://mirrors.tuna.tsinghua.edu.cn/git/git-repo/'

2.2 建立工作目录

mkdir WORKING_DIRECTORY
cd WORKING_DIRECTORY

2.3 初始化仓库

repo init -u https://mirrors.tuna.tsinghua.edu.cn/git/lineageOS/LineageOS/android.git -b cm-14.1 --depth=1

打开.repo/manifest.xml，进行内容替换，将 

<remote  name="github"
         fetch=".."
         review="review.lineageos.org" />

改成 

<remote  name="github"
         fetch="https://github.com/" />

<remote  name="lineage"
         fetch="https://mirrors.tuna.tsinghua.edu.cn/git/lineageOS/"
         review="review.lineageos.org" />

将 

<remote  name="aosp"
         fetch="https://android.googlesource.com"

改成 

<remote  name="aosp"
         fetch="https://aosp.tuna.tsinghua.edu.cn"

将 

<default revision="..."
         remote="github"

改成 

<default revision="..."
         remote="lineage"

2.4 添加hammerhead私有库

在.repo/local_manifests中添加roomservice.xml文件，添加以下内容 

<?xml version="1.0" encoding="UTF-8"?>
<manifest>
<project name="LineageOS/android_packages_resources_devicesettings" path="packages/resources/devicesettings" remote="github" />
<project name="TheMuppets/proprietary_vendor_lge" path="vendor/lge" remote="github" />
</manifest>

私有库分为device specific configuration和kernel以及proprietary blobs，上面只添加了proprietary blobs文件，device specific configuration和hernel会在breakfast命令中自动下载。

2.5 同步源码

repo sync --no-clone-bundle --current-branch

3 编译源码

3.1 编译配置变量

在~/.bashrc中添加以下内容 

export USE_CCACHE=1
ccache -M 50G
export CCACHE_COMPRESS=1
export ANDROID_JACK_VM_ARGS="-Dfile.encoding=UTF-8 -XX:+TieredCompilation -Xmx4G"

添加问之后，source ~/.bashrc。

3.2 执行编译

croot
brunch hammerhead

执行过程中会自动下载部分代码，若下载失败，可以手动编辑.repo/local_manifests/roomservice.xml。添加对应库，然后执行repo sync添加库的路径。（比如device/lge/hammerhead）
