XX理工嵌入式实验1 Linux基本操作

1、https://www.cnblogs.com/biehongli/p/11183504.html
根据这个安装好virtual BOX-虚拟机软件。
2、导入别人制作好的.ova文件
ubuntu虚拟机OVA文件：
https://ws28.cn/f/3oits2ftwfi
虚拟机密码1234
3、导入.ova文件：
https://jingyan.baidu.com/article/870c6fc3551e21b03fe4be14.html
4、Linux常见命令：
https://www.linuxcool.com/
5、Makefile
http://c.biancheng.net/makefile/
6、由于是自己安装的，忘了安装gcc命令 make命令。
在控制台（terminal）输入

sudo apt-get install gcc
sudo apt-get install make

有时间学一下万能的apt包管理器，软件安装就是一行命令的事情。
7、倘若用virtual box打开该.voa文件失败，建议安装另外一款虚拟机软件——Vmware WorkStation，打开方式改为此软件。
8、如果打开后发现上不了网，请检查虚拟机的网卡设置，改为桥接模式或者是NAT。
