MYZR-I.MX6-DEMO Android4.2.2环境搭建

安装ubuntu12.04(install ubuntu12.04)

(如果使用下载明远智睿的虚拟机，请直接跳到 下载源码并解压 这一节)
（if virtual machine downloaded from MYZR is going to be used,please skip to the section"download source code and decompress"）
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。
here it is recommended to users to use operating system of 64bit ubuntu12.04 of which has been proven in compilation by real machine

安装JDK1.6 SE(install JDK1.6 SE)

登陆www.myzr.com.cn的下载专区，下载jdk-6u45-linux-x64.bin文件
login in downloads of www.myzr.com.cn, to download jdk-6u45-linux-x64.bin
$ cd /usr
$ sudo mkdir java
$ cd java
$ sudo cp ~ /jdk-6u45-linux-x64.bin ./
$ sudo chmod 777 ./jdk-6u45-linux-x64.bin
$ sudo ./jdk-6u45-linux-x64.bin
$ sudo gedit /etc/profile
增加以下环境变量
add the following environment variables
export JAVA_HOME=/usr/java/jdk1.6.0_45
export JRE_HOME=$JAVA_HOME/jre
export CLASSPATH=$JAVA_HOME/lib:$JRE_HOME/lib:$CLASSPATH
export PATH=$JAVA_HOME/bin:$PATH:$JRE_HOME/bin
$ source /etc/profile
$ java –version
（看到版本为1.6.0_45就表示成功）
(when version 1.6.0_45 is seen,which represent a success)
