前言

现在转到ODROID-xu4的平台，需要安装ODROID-xu4的交叉编译环境，特此记录！

本文参照ODROID Wiki

Toolchain安装过程

ODROID-xu4使用交叉编译工具链是：gcc-linaro-arm-linux-gnueabihf-4.9-.09_linux

安装过程非常简单：

在/opt下创建自己要安装工具链的目录，我的目录是/opt/odroid-arm-4.9-toolchains

sudo mkdir -p /opt/odroid-arm-4.9-toolchainssudo unxz gcc-linaro-arm-linux-gnueabihf-4.9-.09_linux.tar.xzsudo tar xf gcc-linaro-arm-linux-gnueabihf-4.9-.09_linux.tar -C /opt/odroid-arm-4.9-toolchains

打开目录下的bashrc：vi $HOME/.bashrc，复制以下语句到bashrc的末尾把交叉编译工具链加入到环境变量中

export PATH=/opt/odroid-arm-4.9-toolchains/gcc-linaro-arm-linux-gnueabihf-4.9-.09_linux/bin/:$PATHexport CROSS_COMPILE=arm-linux-gnueabihf-export ARCH=arm

source ~/.bashrc测试，输入arm-linux-gnueabihf-gcc -v,如果打印如下信息，可以找到gcc version4.9.2表示工具链安装成功
