<div>

=安装ubuntu12.04=
在这里建议用户使用64bit的ubuntu12.04的操作系统，已经真机编译验证过。<br>

=安装JDK1.6 SE=
登陆[http://http://www.myzr.com.cn http://www.myzr.com.cn]的下载专区，下载jdk-6u45-linux-x64.bin文件<br>
$ cd /usr<br>
$ sudo mkdir java<br>
$ cd java<br>
$ sudo cp ~ /jdk-6u45-linux-x64.bin ./<br>
$ sudo chmod 777 ./jdk-6u45-linux-x64.bin<br>
$ sudo ./jdk-6u45-linux-x64.bin<br>
$ sudo gedit /etc/profile<br>
增加以下环境变量<br>
export JAVA_HOME=/usr/java/jdk1.6.0_45<br>
export JRE_HOME=$JAVA_HOME/jre<br>
export CLASSPATH=$JAVA_HOME/lib:$JRE_HOME/lib:$CLASSPATH<br>
export PATH=$JAVA_HOME/bin:$PATH:$JRE_HOME/bin<br>
$ source /etc/profile<br>
$ java –version<br>
（看到版本为1.6.0_45就表示成功）<br>

=安装编译Android系统所需要的库=
(详细信息，请看网站[http://source.android.com/source/initializing.html 
http://source.android.com/source/initializing.html]<br>
$ sudo apt-get install git gnupg flex bison gperf build-essential zip curl libc6-dev libncurses5-dev:i386 x11proto-core-dev libx11-dev:i386 libreadline6-dev:i386 libgl1-mesa-glx:i386 libgl1-mesa-dev g++-multilib mingw32 tofrodos python-markdown libxml2-utils xsltproc zlib1g-dev:i386<br>
$ sudo ln -s /usr/lib/i386-linux-gnu/mesa/libGL.so.1 /usr/lib/i386-linux-gnu/libGL.so<br>
$ sudo apt-get install uuid uuid-dev<br>
$ sudo apt-get install zlib1g-dev liblz-dev<br>
$ sudo apt-get install liblzo2-2 liblzo2-dev<br>
$ sudo add-apt-repository ppa:git-core/ppa<br>
$ sudo apt-get update<br>
$ sudo apt-get install git-core curl<br>

=下载源码并解压源码=
==下载源码==
登陆[http://http://www.myzr.com.cn http://www.myzr.com.cn]=下载专区下载Android4.2源码<br>
Android4.4的分卷压缩解压后的源码包：myzr_android-4.4.2_r1.tar.bz2<br>

==解压源码==
$ mkdir ~/myandroid<br>
$ cd ~<br>
$ tar -jxvf myzr_android-4.4.2_r1.tar.bz2 –C ~/myandroid<br>

==编译源码（Android系统）==
===设置环境变量===
$ export ARCH=arm<br>
$ export CROSS_COMPILE=~/myandroid/prebuilts/gcc/linux-x86/arm/arm-eabi-4.6/bin/arm-eabi-
$ export PATH=~/myandroid/bootable/bootloader/uboot-imx/tools:$PATH<br>

===编译uboot===
$ cd ~/myandroid/bootable/bootloader/uboot-imx<br>
$ make distclean<br>
$ make mx6q_sabresd_android_config			(四核配置)<br>
或 $ make mx6dl_sabresd_android_config		(双核简化配置)<br>
或 $ make mx6solo_sabresd_android_config	(单核配置)<br>
$ make<br>

===编译kernel===
$ cd ~/myandroid/kernel_imx<br>
$ make imx6_android_defconfig<br>
$ make uImage<br>

===编译bootimg (uImagel和ramdisk)===
$ cd ~/myandroid<br>
$ source build/envsetup.sh<br>
$ lunch sabresd_6dq-user	(此为发布版本，调试版本改成lunch sabresd_6dq-eng)<br>
$ make bootimage<br>

===编译system===
$ cd ~/myandroid<br>
$ source build/envsetup.sh<br>
$ lunch sabresd_6dq-user (此为发布版本，调试版本改成lunch sabresd_6dq-eng)<br>
$ make<br>


注意：生成的u-boot.bin在~/myandroid/bootable/bootloader/uboot-imx目录下，boot.img和recovery.img和system.img在~/myandroid/out/target/product/sabresd_6dq目录下。<br>
