<p>本教程是基于Ubuntu下Android6.0.1源码以及内核的下载和编译，记录一下，以后也就不用自己去找资料，一遍一遍的尝试了。可以KX上网的,英语好的,直接去 <a href="/misc/goto?guid=4959730047578884112" rel="nofollow,noindex">AndroidSource</a> .</p> <ul> <li>系统环境:Ubuntu14.04LTS</li> <li>Android版本:6.0.1</li> <li>重要网址<br> <a href="/misc/goto?guid=4959730047676472363" rel="nofollow,noindex">清华大学镜像</a><br> <a href="/misc/goto?guid=4959730047578884112" rel="nofollow,noindex">AndroidSource</a></li> </ul> <h2>下载前的准备</h2> <ul> <li> <p>安装OpenJdk</p> <pre> sudo add-apt-repository ppa:openjdk-r/ppa sudo apt-get update sudo apt-get install openjdk-8-jdk sudo update-alternatives --config java java -version </pre> </li> <li> <p>安装git</p> <pre> sudo apt-get install git-core </pre> </li> <li> <p>安装额外的组建</p> <pre> sudo apt-get install gnupg flex bison gperf build-essential \ zip curl zlib1g-dev gcc-multilib g++-multilib libc6-dev-i386 \ lib32ncurses5-dev x11proto-core-dev libx11-dev lib32z-dev ccache \ libgl1-mesa-dev libxml2-utils xsltproc unzip </pre> </li> </ul> <table> <thead> <tr> <th>组建</th> <th>功能</th> <th>介绍网址</th> </tr> </thead> <tbody> <tr> <td>gnupg</td> <td>加密工具</td> <td><a href="/misc/goto?guid=4958879096392807186" rel="nofollow,noindex">GPG入门教程</a></td> </tr> <tr> <td>flex</td> <td>The Fast Lexical Analyzer</td> <td><a href="/misc/goto?guid=4959730047804087584" rel="nofollow,noindex">快速的语法分析工具</a></td> </tr> <tr> <td>bison</td> <td>用于自动生成语法分析器程序</td> <td><a href="/misc/goto?guid=4959730047886061930" rel="nofollow,noindex">自动生成语法分析器程序</a></td> </tr> <tr> <td>gperf</td> <td>完美的散列函数生成器</td> <td><a href="/misc/goto?guid=4959730047975588619" rel="nofollow,noindex">使用 gperf 实现高效的 C/C++ 命令行处理</a></td> </tr> <tr> <td>build-essential</td> <td>编译内核中make menuconfig进图形编译</td> <td><a href="/misc/goto?guid=4959730048052824453" rel="nofollow,noindex">build-essential</a></td> </tr> <tr> <td>zip</td> <td>Linux 下zip包的压缩与解压</td> <td><a href="/misc/goto?guid=4959730048143877670" rel="nofollow,noindex">Linux 下zip包的压缩与解压</a></td> </tr> <tr> <td>curl</td> <td>网络请求和提取工具</td> <td><a href="/misc/goto?guid=4958188997903938385" rel="nofollow,noindex">curl网站开发指南</a></td> </tr> <tr> <td>zlib1g-dev</td> <td>用于发现gzip和PKZIP的工具</td> <td><a href="/misc/goto?guid=4959730048265490926" rel="nofollow,noindex">Binary package “zlib1g-dev” in ubuntu trusty</a></td> </tr> <tr> <td>gcc-multilib</td> <td>允许在64位机器中运行32位应用</td> <td><a href="/misc/goto?guid=4959730048352675480" rel="nofollow,noindex">multilib</a></td> </tr> <tr> <td>g++-multilib</td> <td>同上(g++编译工具)</td> <td><a href="/misc/goto?guid=4959730048445479510" rel="nofollow,noindex">多平台支持</a></td> </tr> <tr> <td>libc6-dev-i386</td> <td>Embedded GNU C Library: 32-bit development libraries for AMD64</td> <td><a href="/misc/goto?guid=4959730048519846838" rel="nofollow,noindex">libc6-dev-i386</a></td> </tr> <tr> <td>lib32ncurses5-dev</td> <td>待完善</td> <td>待完善</td> </tr> <tr> <td>x11proto-core-dev</td> <td>待完善</td> <td>待完善</td> </tr> <tr> <td>libx11-dev</td> <td>待完善</td> <td>待完善</td> </tr> <tr> <td>lib32z-dev</td> <td>待完善</td> <td>待完善</td> </tr> <tr> <td>ccache</td> <td>待完善</td> <td>待完善</td> </tr> <tr> <td>libgl1-mesa-dev</td> <td>待完善</td> <td>待完善</td> </tr> <tr> <td>libxml2-utils</td> <td>待完善</td> <td>待完善</td> </tr> <tr> <td>xsltproc</td> <td>待完善</td> <td>待完善</td> </tr> <tr> <td>unzip</td> <td>待完善</td> <td>待完善</td> </tr> </tbody> </table> <h2>下载</h2> <p>因为网络以及墙的原因，我们使用清华大学镜像，步骤如下:</p> <ul> <li> <p>下载repo工具</p> <pre> mkdir ~/bin PATH=~/bin:$PATH curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo chmod a+x ~/bin/repo </pre> </li> <li> <p>下载源码</p> <pre> wget https://mirrors.tuna.tsinghua.edu.cn/aosp-monthly/aosp-latest.tar #
