(一) odroid-xu4交叉编译过程

目录

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-4.9-2014.09_linux
安装过程非常简单：

1. 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-toolchains
sudo unxz gcc-linaro-arm-linux-gnueabihf-4.9-2014.09_linux.tar.xz
sudo tar xf gcc-linaro-arm-linux-gnueabihf-4.9-2014.09_linux.tar -C /opt/odroid-arm-4.9-toolchains

2. 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-4.9-2014.09_linux/bin/:$PATH
export CROSS_COMPILE=arm-linux-gnueabihf-
export ARCH=arm

3. source ~/.bashrc
4. 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

总结

刚开始接触ODROID，先记录下来，方便查询！
