编译前请参考Android-x86项目主页中有关源码下载部分的相关内容来获取所需要的源码。建议在获取对应版本AOSP源码的基础上进行进一步源码的获取，AOSP源码获取详见编译指南。
-
Ubuntu 14.04环境下可通过安装下述软件包来构建编译环境（替换AOSP中Installing required packages步骤所提供的软件包）。
sudo apt-get install -y git-core gnupg flex bison gperf build-essential zip curl libc6-dev libncurses5-dev x11proto-core-dev libx11-dev libreadline6-dev libgl1-mesa-dev g++-multilib mingw32 schedtool tofrodos python-markdown pngquant libxml2-utils xsltproc zlib1g-dev libxext-dev openjdk-7-jdk gettext bc mtools lib32z1 lib32ncurses5 lib32bz2-1.0 python-pip libyaml-dev python-dev squashfs-tools
sudo pip install prettytable Mako pyaml dateutils --upgrade
- 另外编译Android-x86的编译命令语句，输出目标，输出结果等都与AOSP有着相当的不同，请查阅wiki中的一些Android-x86编译记录来获取更详细的编译指南。
详细步骤
下载
帮助
###仓库地址：
- git://aosp.tuna.tsinghua.edu.cn/android/
下载android 源码
下载 repo
git clone git://aosp.tuna.tsinghua.edu.cn/android/git-repo.git/
修改repo
google的地址
REPO_URL = 'https://gerrit.googlesource.com/git-repo'
改为清华大学的地址
REPO_URL = 'git://aosp.tuna.tsinghua.edu.cn/android/git-repo'
下载 manifest
google 的地址
$ repo init -u https://android.googlesource.com/platform/manifest
改为清华大学的地址
$ repo init -u git://aosp.tuna.tsinghua.edu.cn/android/platform/manifest
同步源码
- 还是和以前一样
$ repo sync
替换已有的AOSP源代码的remote
如果你之前已经通过某种途径获得了AOSP的源码，但是你希望以后通过TUNA同步，只需要将.repo/manifest.xml中的
<remote name="aosp"
fetch=".."
review="https://android-review.googlesource.com/" />
改为下面的code即可：
<remote name="aosp"
fetch="git://aosp.tuna.tsinghua.edu.cn/android/"
review="https://android-review.googlesource.com/" />
这个方法也可以用来在同步Cyanogenmod代码的时候从TUNA同步部分代码
编译
Initializing a Build Environment
Installing the JDK
$ sudo apt-get update
$ sudo apt-get install openjdk-7-jdk
Installing required packages
sudo apt-get install bison g++-multilib git gperf libxml2-utils make zlib1g-dev:i386 zip
Building the System
Initialize
$ source build/envsetup.sh
Choose a Target
$ lunch 20
Update api
make update-api
Build the Code
make -j16
在TF笔记本上，结果如下 ：
build mini_emulator_x86-userdebug
#### make completed successfully (01:24:32 (hh:mm:ss)) ####
download and compile the kernel
download
- git clone https://android.googlesource.com/kernel/goldfish.git
build
mkdir output-goldfish
cd goldfish
git branch -a
git checkout android-goldfish-3.10 //这个分支虽然新，但有bug, 用emulator（android-sdk带的）不行，kernel crash
git checkout android-goldfish-3.10-m-dev //可以正常编译并运行！
第一种编译方法
/backup/android-related/android-repo/prebuilts/qemu-kernel/build-kernel.sh --arch=x86_64 --out=/backup/android-related/kernel-related/output-goldfish
第一种编译方法 结果如下：
OBJCOPY arch/x86/boot/setup.bin
BUILD arch/x86/boot/bzImage
Setup is 15440 bytes (padded to 15872 bytes).
System is 4284 kB
CRC a721525e
Kernel: arch/x86/boot/bzImage is ready (#1)
Kernel x86_64_emu prebuilt images (kernel-qemu and vmlinux-qemu) copied to /backup/android-related/kernel-related/output-goldfish successfully !

问题
无法用多线程下载tuna mirror的android
一个IP只支持４个下载线程，所以 最多 repo sync -j4
在安装zlib1g-dev:i386时，无法安装，待解决。
在执行 make updat-api时，碰到java的版本问题
************************************************************
You are attempting to build with the incorrect version
of java.
Your version is: Picked up JAVA_TOOL_OPTIONS: -javaagent:/usr/share/java/jayatanaag.jar
java version "1.7.0_79" OpenJDK Runtime Environment (IcedTea 2.5.6)
(7u79-2.5.6-0ubuntu1.15.04.1) OpenJDK 64-Bit Server VM (build 24.79-b02, mixed mode).
The required version is: "1.7.x"
Please follow the machine setup instructions at
https://source.android.com/source/initializing.html
************************************************************
解决办法 http://askubuntu.com/questions/664963/java-7-reporting-not-installed
In build/core/main.mk, the java_version_str contains the output of "java -version":
Picked up JAVA_TOOL_OPTIONS: -javaagent:/usr/share/java/jayatanaag.jar
java version "1.7.0_79"
OpenJDK Runtime Environment (IcedTea 2.5.6) (7u79-2.5.6-0ubuntu1.15.04.1)
OpenJDK 64-Bit Server VM (build 24.79-b02, mixed mode)
The java_version is supposed to extract "1.7.0_79" using grep. The caret at the beginning of the grep regular expression "^java" indicates that the author intended to be able to find a line starting with "java". Unfortunately, GNU Make variables do not store the line endings. So the grep only sees one giant line starting with "Picked".
The grep works accidentally when the "java version" happens to be on the first line. This is probably why "unset _JAVA_OPTIONS" was added in java_version_str, because it was causing similar problems.
The simplest solution is to follow the current band-aid solution by adding "unset JAVA_TOOL_OPTIONS" to java_version_str:
in LINE 139,140
java_version_str := $(shell unset _JAVA_OPTIONS && unset JAVA_TOOL_OPTIONS && java -version 2>&1)
javac_version_str := $(shell unset _JAVA_OPTIONS && unset JAVA_TOOL_OPTIONS && javac -version 2>&1)
The real solution would be to not use an intermediate variable java_version_str and perform the grep directly:
java_version := $(shell java -version 2>&1 | grep '^java .*[ "]1\.7[\. "$$]')
javac_version := $(shell java -version 2>&1 | grep '[ "]1\.7[\. "$$]')
