Ubuntu 16.04 LTS 成功编译 Android 6.0 源码教程

1 前言

经过3天奋战，终于在Ubuntu 16.04上把Android 6.0的源码编译出来了，各种配置，各种error，各种爬坑，特写此博客记录爬坑经历。先上图，Ubuntu上编译完后成功运行模拟器，如图：

2 编译环境

UbuntuKylin 16.04 LTS
Android 6.0_r1
Open JDK 7

3 准备工作

(1) 下载Android 6.0源码.

Androdi 6.0源码下载地址: http://pan.baidu.com/s/1o6N86a2

感谢下面这位博主上传源码，我也是从他的博客下载的源码：

http://blog.csdn.net/ilittleone/article/details/6823441

下载源码请在Windows下面下载，迅雷不解释。 
注意：源码的存放路径不能有中文，否则编译到系统内置的apk的时候会报错无法解析class.dex文件

(2) 解压源码,合并文件。 

下载完毕后，使用下面命令合并：

<code class="hljs avrasm has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;">cat Android6_r1_*>Android6_r1<span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.tgz</span></code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li></ul><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li></ul>

合并完后，使用下面命令校验hash:

<code class="hljs avrasm has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;">md5sum Android6_r1<span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.tgz</span></code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li></ul><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li></ul>

此时会生成一个hash串，如图：



对比你下载的文件里面的hash.txt，如果一致那么继续，不一致则文件损坏，重新下载。

(3) 解压源码。

tar -zxvf Android6_r1.tgz

解压源码是个漫长的过程，解压后会在当前目录下生成一个mydroid的文件夹。如果你发现源码的路径有中文，需要移动源码，请复制压缩包，然后再使用命令解压，而不要直接复制解压后的文件夹。

(4) 安装Ubuntu 16.04 

编译Android源码最好直接安装Linux，不要使用虚拟机，编译源码是个漫长的过程，虚拟机要十几个小时，博主直接在电脑上装Ubuntu，编译只需要3个小时。实体机可避免虚拟机的很多问题，例如：磁盘空间不足，内存不够等等。更重要的是，编译源码是个不断爬坑的过程，实体机可以很快的遇到错误，然后解决问题，继续编译，再次遇到错误，而虚拟机这个周期会很漫长，因而浪费大量时间。实体机解压速度也比虚拟机快得多。Ubuntu与windows兼容做的很好，可以直接把Ubuntu当作一个windows程序安装，也可以单独安装，如果单独安装请务必给/home分区分配至少120G空间，因为编译后的Android系统真的很大。 
强烈建议下载Ubuntu镜像，然后使用软碟通刻录到U盘，通过U盘把Ubuntu安装到物理机器上。

(5) Ubuntu安装教程参考下面链接,Ubuntu 16.04安装方法也是一样的 ：

Ubuntu 16.04请务必使用上面的依赖，Ubuntu 16.04需要的依赖和Ubuntu 14.04所需要的依赖是不同的，博主照着Ubuntu 14.04的依赖结果掉进大坑，详见后面的编译过程记录.

5 安装open JDK7

从Android 6.0开始Android源码的编译需要安装OpenJDK,不能使用Oracle JDK,而且Android 6.0只能使用OpenJDK7,如下图：



由于Ubuntu 16.04没有OpenJDK7的源，因此在16.04上安装OpenJDK7需要执行下面的命令：

<code class="hljs lasso has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;">sudo add<span class="hljs-attribute" style="box-sizing: border-box;">-apt</span><span class="hljs-attribute" style="box-sizing: border-box;">-repository</span> ppa:openjdk<span class="hljs-attribute" style="box-sizing: border-box;">-r</span>/ppa
sudo apt<span class="hljs-attribute" style="box-sizing: border-box;">-get</span> update
sudo apt<span class="hljs-attribute" style="box-sizing: border-box;">-get</span> install openjdk<span class="hljs-subst" style="color: rgb(0, 0, 0); box-sizing: border-box;">-</span><span class="hljs-number" style="color: rgb(0, 102, 102); box-sizing: border-box;">7</span><span class="hljs-attribute" style="box-sizing: border-box;">-jdk</span> </code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li><li style="box-sizing: border-box; padding: 0px 5px;">3</li></ul><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li><li style="box-sizing: border-box; padding: 0px 5px;">3</li></ul>

配置OpenJDK.打开/etc/profile文件:

<code class="hljs bash has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;"><span class="hljs-built_in" style="color: rgb(102, 0, 102); box-sizing: border-box;">sudo</span> gedit /etc/profile</code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li></ul><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li></ul>

在末尾追加下面代码：

<code class="hljs bash has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;"><span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">export</span> JAVA_HOME=/usr/lib/jvm/java-<span class="hljs-number" style="color: rgb(0, 102, 102); box-sizing: border-box;">7</span>-openjdk-amd64

修改了/etc/profile文件需要重启才能生效，但使用下面命令可以在不重启的情况下在当前bash环境生效：

<code class="hljs bash has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;"><span class="hljs-built_in" style="color: rgb(102, 0, 102); box-sizing: border-box;">source</span> /etc/profile</code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li></ul><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li></ul>

检查OpenJDK配置是否正确:

<code class="hljs livecodeserver has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;">java -<span class="hljs-built_in" style="color: rgb(102, 0, 102); box-sizing: border-box;">version</span></code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li></ul><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li></ul>

配置正确则如下图:

6 修改源码

修改 

mydroid/art/build/Android.common_build.mk

 文件，定位到75行，将下面的代码：

<code class="hljs perl has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;">ifne<span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">q (<span class="hljs-variable" style="color: rgb(102, 0, 102); box-sizing: border-box;">$(</span>WITHOUT_HOST_CLANG)</span>,true)</code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li></ul><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li></ul>

改为：

<code class="hljs perl has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;">ife<span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">q (<span class="hljs-variable" style="color: rgb(102, 0, 102); box-sizing: border-box;">$(</span>WITHOUT_HOST_CLANG)</span>,false)</code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li></ul><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li></ul>

如果不修改这里，会遇到一个比较棘手的编译错误，修改的目的是把CLANG这个编译选项关掉，详见后面的编译记录，百度搜狗都无解，这个错误只会在Ubuntu16.04上遇到，Ubuntu14.04则不存在这个问题，解决这个编译错误花费一天时间，还好咱英语好，在歪果人的论坛上看了几篇帖子，终于搞定了。这里顺便说一下小技巧： 
遇到编译错误，请把error后面的错误信息全部复制，然后用搜狗搜英文网页，不要用百度那个渣渣

7 开始编译

(1) 在 .bashrc文件末尾添加：export USE_CCACHE = 1

<code class="hljs bash has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;"><span class="hljs-built_in" style="color: rgb(102, 0, 102); box-sizing: border-box;">echo</span> <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">export</span> USE_CCACHE=<span class="hljs-number" style="color: rgb(0, 102, 102); box-sizing: border-box;">1</span> >> ~/.bashrc</code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li></ul><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li></ul>

(2) 为了提高编译效率，设置编译器高速缓存:

<code class="hljs lasso has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;">prebuilts/misc/linux<span class="hljs-attribute" style="box-sizing: border-box;">-x86</span>/ccache/ccache <span class="hljs-attribute" style="box-sizing: border-box;">-M</span> <span class="hljs-number" style="color: rgb(0, 102, 102); box-sizing: border-box;">50</span>G</code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li></ul><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li></ul>

(3) 接着导入编译Android源码所需的环境变量和其它参数:

<code class="hljs bash has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;"><span class="hljs-built_in" style="color: rgb(102, 0, 102); box-sizing: border-box;">source</span> build/envsetup.sh</code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li></ul><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li></ul>

(4) 运行lunch命令选择编译目标:

<code class="hljs  has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;">lunch</code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li></ul><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li></ul>

选择1： 



(5) 开始编译，执行make -j8, 8为同时编译的线程数，一般google推荐这个数字为2倍的cpu个数再加上2，比如4核，就是10。博主使用的是8:

<code class="hljs lasso has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;">make <span class="hljs-attribute" style="box-sizing: border-box;">-j8</span></code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li></ul><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li></ul>

关于cpu个数，可以用下面命令查看:

<code class="hljs haskell has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;"><span class="hljs-title" style="box-sizing: border-box;">cat</span>  /<span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">proc</span>/cpuinfo</code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li></ul><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li></ul>

好了，开始编译了，接下来就是不断error，不断修复，继续编译的过程,下面记录我的爬坑经历

7 编译记录

我是参照下面这篇文章开始编译的：

http://www.linuxidc.com/Linux/2016-01/127292p2.htm

如果一帆风顺，我也就用不着写这篇博客了，然而他用的是Ubuntu14.04，我用的最新的Ubuntu16.04，按照上面这篇博文，遇到很多坑，这里记录以下爬坑经历： 

(1) 依赖不同。Ubuntu 14和16的依赖选项是不同的： 



于是将

libsdl1.2-dev

改为

libsdl-dev

,将

mingw32

去掉

(2) JDK配置错误。 

先用Oracle JDK8报下面错： 



改为Oracle JDK7报下面错： 



后改为OpenJDK7解决问题。

(3) 大坑。接着遇到下面错误: 



仔细看错误：

<code class="hljs vbnet has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;">clang: <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">error</span>: linker command failed <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">with</span> <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">exit</span> code</code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li></ul><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li></ul>

其实这个是系统使用clang编辑器报的错，百度了一下，解决方法一般是将

art/build/Android.common_build.mk

文件

ifneq
($(WITHOUT_HOST_CLANG),true)

改为

ifeq ($(WITHOUT_HOST_CLANG),false)

 

然而纸上得来终觉浅，绝知此事要躬行，因为，这并没有什么卵用，至少现在没有卵用。不信，请看下面的帖子：

http://ask.csdn.net/questions/253318

我试了一下，也没用，还是没解决问题，好像这个是新系统的兼容问题，百度搜狗一天，没有进展，后来发现了下面这篇帖子,也是14.04编译Android6.0的：

http://blog.csdn.net/lewif/article/details/49762993

抱着反正无聊试一试的想法，把上面这篇帖子中的依赖一通复制(所以最终用的依赖是两篇帖子加起来的依赖)：

<code class="hljs lasso has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;">sudo apt<span class="hljs-attribute" style="box-sizing: border-box;">-get</span> install git<span class="hljs-attribute" style="box-sizing: border-box;">-core</span> gnupg flex bison gperf build<span class="hljs-attribute" style="box-sizing: border-box;">-essential</span> <span class="hljs-subst" style="color: rgb(0, 0, 0); box-sizing: border-box;">\</span>

然后

make clean

，重新再来，接着就睡觉去了。 

一觉醒来，然后……..你以为我就编粗来了？呵呵，这个错误是终于编过去了，可是又遇到下面的错误： 



解决这个错误，又花费一番力气，在歪果人的论坛上看到下面这篇帖子：

http://forum.xda-developers.com/chef-central/android/guide-how-to-setup-ubuntu-16-04-lts-t3363669/page2

注意看这个帖子的15楼，哈哈，这个时候找到解决方法了,再修改

art / build/Android.common_build.mk

文件

<code class="hljs perl has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;"> ifne<span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">q (<span class="hljs-variable" style="color: rgb(102, 0, 102); box-sizing: border-box;">$(</span>WITHOUT_HOST_CLANG)</span>,true)</code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li></ul><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li></ul>

改为：

重新编译，解决问题。

(4) 中文路径，坑。 



遇到这个问题也是很难百度到，哎，最后把源码换到了全英文的路径下面，解决这个问题。注意移动源码的时候不要直接复制mydroid文件夹，一个小时都复制不完，所以正确的方法是复制压缩包，然后再解压一遍。 

接下来就编译成功了。

8 编译成功

编译成功后如下图： 



进入mydroid/out/target/product/generic目录，可以看到编译好的文件： 



启动模拟器：

<code class="hljs  has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;">emulator</code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li></ul><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li></ul>

稍等一会，就可以出现开头的模拟器画面了，哈哈，打完收工。

9 附录：Ubuntu 16.04编译ROM英文教程

最后，附上在看帖子的时候发现的，在Ubuntu16.04上编译AOSP、CyanogenMod的教程，当然是英文的啦：

10 总结

Android系统源码的编译就是不断和各种error做斗争的过程，考验程序员获取信息的能力，遇到error的时候只能各种百度搜狗，但这也是非常锻炼能力的过程，博主在编译过程中最大的体会就是：英语一定要好，哈哈。如果你成功编译出来了，或者编译遇到问题，欢迎给我留言。
