从零配置linuxC++环境

先安装一个vim

sudo apt-get install vim

再更新软件源

先打开软件源配置文件

sudo vim /etc/apt/sources.list

在文件末尾删除原有的软件源，加入如下

deb-src http://archive.ubuntu.com/ubuntu xenial main restricted 
deb http://mirrors.aliyun.com/ubuntu/ xenial main restricted
deb-src http://mirrors.aliyun.com/ubuntu/ xenial main restricted multiverse universe 
deb http://mirrors.aliyun.com/ubuntu/ xenial-updates main restricted
deb-src http://mirrors.aliyun.com/ubuntu/ xenial-updates main restricted multiverse universe 
deb http://mirrors.aliyun.com/ubuntu/ xenial universe
deb http://mirrors.aliyun.com/ubuntu/ xenial-updates universe
deb http://mirrors.aliyun.com/ubuntu/ xenial multiverse
deb http://mirrors.aliyun.com/ubuntu/ xenial-updates multiverse
deb http://mirrors.aliyun.com/ubuntu/ xenial-backports main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ xenial-backports main restricted universe multiverse 
deb http://archive.canonical.com/ubuntu xenial partner
deb-src http://archive.canonical.com/ubuntu xenial partner
deb http://mirrors.aliyun.com/ubuntu/ xenial-security main restricted
deb-src http://mirrors.aliyun.com/ubuntu/ xenial-security main restricted multiverse universe 
deb http://mirrors.aliyun.com/ubuntu/ xenial-security universe
deb http://mirrors.aliyun.com/ubuntu/ xenial-security multiverse

然后更新

sudo apt-get update
sudo apt-get upgrade

然后安装g++ gbd cmake

sudo apt-get install g++
sudo apt-get install gdb
sudo apt-get install cmake

就可以使用C++了。

个人需要安装的库为

#安装eigen库
sudo apt-get install libeigen3-dev
#映射路径
sudo ln -s /usr/include/eigen3/Eigen /usr/include/Eigen
