准备工作

1. 下载交叉编译工具：
   百度网盘：链接：https://pan.baidu.com/s/1g4frOXmSnQU1NsOj8Zu60A

       提取码：rdap

2. ubuntu版本：

   vmare安装的ubuntu18.04 amd64版本

    dopi@ubuntu:~$ cat /proc/version
   Linux version 5.3.0-62-generic (buildd@lcy01-amd64-004) (gcc version 7.5.0 (Ubuntu 7.5.0-3ubuntu1~18.04)) #56~18.04.1-Ubuntu SMP Wed Jun 24 16:17:03 UTC 2020

交叉编译

1. 首先更换镜像源，再更新

打开镜像源，ubuntu18更新源：https://mirrors.tuna.tsinghua.edu.cn/help/ubuntu/
选择ubuntu18.04：

修改权限，复制到 source.list 中，保存退出。

sudo chmod 777 /etc/apt/sources.list
vi /etc/apt/sources.list

2. 首先更新系统

更新命令：

 sudo apt-get update && sudo apt-get install -y bzip2 build-essential libc6-dev-i386 ia32-libs lib32z1-dev libncurses5 libncurses5-dev u-boot-tools vim squashfs-tools gettext git zip subversion bc

错误提示：Package ‘ia32-libs’ has no installation candidate

dopi@ubuntu:/home/ev200_tools$ sudo apt-get update && sudo apt-get install -y bzip2 build-essential libc6-dev-i386 ia32-libs lib32z1-dev libncurses5 libncurses5-dev u-boot-tools vim squashfs-tools gettext git zip subversion bc

Package ia32-libs is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
However the following packages replace it:
  lib32ncurses5 lib32z1
E: Package 'ia32-libs' has no installation candidate

解决方法：

sudo apt-get install lib32z1 lib32ncurses5 
sudo apt-get install lib32stdc++6

去掉ia32-libs，重新更新系统：

sudo apt-get update && sudo apt-get install -y bzip2 build-essential libc6-dev-i386  lib32z1-dev libncurses5 libncurses5-dev u-boot-tools vim squashfs-tools gettext git zip subversion bc

3. 把arm-himix100-linux.tgz拷贝到ubuntu18中

下载的arm-himix100-linux.tgz拷贝到ubuntu18中，我是通过vmare的共享文件夹拷贝到ubuntu18中的。

 dopi@ubuntu:/mnt/hgfs$ cd dopi-linux/
dopi@ubuntu:/mnt/hgfs/dopi-linux$ ls
arm-himix100-linux.tgz
dopi@ubuntu:/mnt/hgfs/dopi-linux$ cp arm-himix100-linux.tgz /home/ev200_tools/

4. 解压 tar -zxvf arm-himix100-linux.tgz

dopi@ubuntu:/mnt/hgfs/dopi-linux$ cd /home/ev200_tools/
dopi@ubuntu:/home/ev200_tools$ ls
arm-himix100-linux.tgz
dopi@ubuntu:/home/ev200_tools$ tar -zxvf arm-himix100-linux.tgz 
arm-himix100-linux/
arm-himix100-linux/arm-himix100-linux.install
arm-himix100-linux/runtime_uclibc.tgz
arm-himix100-linux/arm-himix100-linux.tar.bz2
arm-himix100-linux/readme.txt

4. 安装

安装命令

  cd arm-himix100-linux/
  sudo ./arm-himix100-linux.install

执行过程，到此安装交叉编译工具链完成。

dopi@ubuntu:/home/ev200_tools$ ls
arm-himix100-linux  arm-himix100-linux.tgz
dopi@ubuntu:/home/ev200_tools$ cd arm-himix100-linux/
dopi@ubuntu:/home/ev200_tools/arm-himix100-linux$ sudo ./arm-himix100-linux.install
