Linux 交叉编译器环境搭建和验证

• 解压文件

下载gcc-linaro-arm-linux-gnueabihf-4.7-2013.03-20130313_linux.tar.bz2

解压 $ tar -jxvf gcc-linaro-arm-linux-gnueabihf-4.7-2013.03-20130313_linux.tar.bz2
解压完成出现同名文件夹：gcc-linaro-arm-linux-gnueabihf-4.7-2013.03-20130313_linux

• 建立目录

sudo mkdir /usr/local/arm

• 复制文件

sudo cp -r gcc-linaro-arm-linux-gnueabihf-4.7-2013.03-20130313_linux /opt/gcc-linaro-arm-linux-gnueabihf-4.7-2013.03-20130313_linux

• 配置环境变量

修改/etc/bash.bashrc文件

sudo gedit /etc/bash.bashrc

在最后加上 export PATH=$PATH:/opt/gcc-linaro-arm-linux-gnueabihf-4.7-2013.03-20130313_linux/bin

source /root/.bashrc或者./etc/bash.bashrc

• 查看交叉编译环境

    $ arm-linux-gnueabihf-gcc -v

如下所示

[imx6ull-sbc]:/home/imx6/imx6ull-sbc> arm-linux-gnueabihf-gcc -v
