查看“Windows-7 Ubuntu-14.04.5 64位开发环境指导”的源代码

==安装虚拟机==
:到网盘下载vmware 10和Ubuntu 14.04镜像文件，安装步骤参考《vmware虚拟机安装使用教程》。
:*网盘请联系管理员。

== 开发环境搭建 ==
:安装基本的软件包
 $ sudo apt-get install uuid uuid-dev zlib1g-dev liblz-dev liblzo2-2 liblzo2-dev git-core curl lib32ncurses5 lib32z1 lib32bz2-1.0 lib32stdc++6 u-boot-tools bison flex gperf
:备份更新源文件
 $ sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak
:修改更新源文件（修改为阿里云的源）
 $ sudo vim /etc/apt/sources.list

:更新源列表：
 $ sudo apt-get update
== 安装交叉编译工具链 ==
:到网盘下载gcc-4.6.2-fsl-linaro-toolchain.tar.gz文件拷贝并解压到你的工作目录下，然后解压
<pre>
$cd ~
$mkdir work
$mv gcc-4.6.2-fsl-linaro-toolchain.tar.gz  work
$cd work
$tar zxvf gcc-4.6.2-fsl-linaro-toolchain.tar.gz -C /opt/
</pre>
:配置全局的环境变量，修改/etc/bash.bashrc文件，命令如下：
 $ sudo vim /etc/bash.bashrc
:在文件末尾加入如下几行：
<pre>
export  ARCH=arm
export  CROSS_COMPILE=/opt/fsl-linaro-toolchain/bin/arm-none-linux-gnueabi-
export  PATH=/opt/fsl-linaro-toolchain/bin:$PATH
</pre>
:如下图：
[[文件:Imx6-cross.jpg|620px]]
:使环境变量生效，查看当前交叉编译器版本
 $ source /etc/bash.bashrc
 $ arm-linux-gcc –v
:输出如下图：
