【NanoPi2试用体验】编译内核准备篇-在32位Ubuntu电脑上搭建编译环境

NANOPI2官方WIKI只给了64位搭建编译环境的方法，对于像我这样只有32位电脑或者只安装了32位LINUX的朋友就没有说明，下面我介绍的方法可以解决这个问题。打开synaptic package manager按CTRL+F输入ARM按OK进行搜索，勾选cpp-4.9-arm-linux-gnueabihf gcc-4.9-arm-linux-gnueabihf gcc-4.9-arm-linux-gnueabihf-base libc6-armhf-cross libc6-dev-armhf-cross libgcc-4.9-dev-armhf-cross libgcc1-armhf-cross libgo0-armhf-cross libsfgcc1-armhf-cross libsfstdc++6-armhf-cross libstdc++6-armhf-cross linux-libc-dev-armhf-cross pkg-config-arm-linux-gnueabihf u-boot-tools android-tools-fastboot git vim，然后选择Mark for Installation和Apply.
打开terminal
cd  ~
git clone https://github.com/friendlyarm/prebuilts.git
sudo tar xf ~/prebuilts/gcc/arm-linux-gcc-4.5.1-v6-vfp.tar.xz
cd ~/prebuilts/gcc/opt
sudo cp -R * /opt
sudo vi ~/.bashrc
在最下面复制粘贴下面两行进去后输入:wq保存
export PATH=/opt/FriendlyARM/toolchain/4.5.1/bin:$PATH
export GCC_COLORS=auto
输入下面命令使上面修改生效
cd ~
. ~/.bashrc
输入下面命令测试
arm-linux-gcc -v
输出和下面一样则成功
