# 以AOSP14项目为例ShareBuild分布式编译详细配置方法

##  编译环境准备

### 安装 Sharebuild

* 参与编译的同一个局域网内的A、B、C等所有节点上安装ninja2和sharebuild:
```
wget -c https://raw.githubusercontent.com/ninja-cloudbuild/ninja2/refs/heads/main/install.sh && chmod +x install.sh && sudo ./install.sh
```

* 确保所有节点上均安装配置好了项目的编译环境，即所有节点上均能采用ninja成功单机编译项目。

### 安装AOSP项目编译环境

* 参与编译的同一个局域网内的A、B、C等所有节点上安装编译环境依赖:

```bash
# 安装核心开发工具和库
sudo apt-get install git-core gnupg flex bison build-essential zip curl zlib1g-dev gcc-multilib g++-multilib libc6-dev-i386 libncurses5 lib32ncurses5-dev x11proto-core-dev libx11-dev lib32z1-dev libgl1-mesa-dev libxml2-utils xsltproc unzip fontconfig

# 安装Android 14所需的Java环境
sudo apt-get install openjdk-17-jdk

# 确保Python 3环境正确安装
sudo apt-get install python3 python3-pip
```

### 下载 AOSP 源码并执行单机编译

* 选择任一节点作为客户端节点，下载AOSP14源码:

```bash
mkdir ~/bin && curl https://mirrors.tuna.tsinghua.edu.cn/git/git-repo > ~/bin/repo && chmod a+x ~/bin/repo 
export PATH=~/bin:$PATH

repo init --depth=1 --partial-clone -u https://mirrors.tuna.tsinghua.edu.cn/git/AOSP/platform/manifest -b android-14.0.0_r2
repo sync -j16

cd android-14.0.0_r2
source build/envsetup.sh  # 初始化环境
lunch aosp_arm-eng        # 选择目标配置
make                      # 执行单机编译
```
编译成功后可以看到：
```

#### build completed successfully (02:20:12 (hh:mm:ss)) ####

```

### 配置AOSP项目开启ShareBuild模式

* 到 AOSP 项目根目录下执行 setup_sharebuild_forAOSP14.sh 配置ShareBuild分布式编译
```
cd android-14.0.0_r2
/etc/ninja2/aosp14/setup_sharebuild_forAOSP14.sh
```

* 在项目根目录下执行分布式编译

```bash
source build/envsetup.sh  # 初始化环境
lunch aosp_arm-eng        # 选择目标配置
make                      # 执行分布式编译
```
编译成功后可以看到：

* 客户端节点：
```
