ubuntu18.04(64位) 安装交叉编译工具

ubuntu18.04(64位) 安装交叉编译工具（arm-linux-gcc-3.4.5）
1.将交叉编译工具上传到ubuntu，并解压
交叉编译工具百度云资源：

提取码：9k0a

sudo tar -jxvf  arm-linux-gcc-3.4.5-glibc-2.3.6.tar.bz2 

2.创建一个新目录 /usr/local/arm,且赋予全部权限
sudo mkdir /usr/local/arm

sudo chmod 777 /usr/local/arm

3.将第1步解压出的目录（gcc-3.4.5-glibc-2.3.6）拷贝到/usr/local/arm
sudo cp -r gcc-3.4.5-glibc-2.3.6 /usr/local/arm

4.配置环境变量和库变量
sudo gedit /etc/profile

sudo gedit ~/.bashrc

在这两个文件的最后添加：

export PATH=$PATH:/usr/local/arm/gcc-3.4.5-glibc-2.3.6/bin
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/arm/gcc-3.4.5-glibc-2.3.6/lib

5.更新系统路径，使添加的环境变量立即生效
source /etc/profile
source ~/.bashrc

6.添加库支持
sudo apt install libc6-i386

7.若上一步不成功可能是apt源的问题，我们需要更换apt源
sudo gedit  /etc/apt/sources.list

把原有的内容替换为阿里源

deb http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse


更新apt源

sudo apt update
sudo apt upgrade

再回到第6步

8.查看版本
arm-linux-gcc -v
