Vim C/C++开发配置

1.基础准备

安装g++ gcc git cmake

sudo apt-get install g++ gcc cmake git

安装vim

sudo apt-get install vim

2.安装Vim插件管理工具Vundle

Vundle让你可以非常轻松地安装、更新、搜索和清理插件

按ctrl + alt + T打开 Terminal
进入到~/.vim文件夹中，如果没有则创建
```
~$ cd ~/.vim/
#如果无文件夹
#mkdir .vim
```
在~/.vim目录下创建一个bundle目录,下载Vundle.vim到~/.vim/bundle目录下
```
~/.vim$ mkdir bundle
~/.vim$ git clone https://github.com/gmarik/Vundle.vim.git ~/.vim/bundle/Vundle.vim
```
如果无法下载，可以直接点击链接下载到该文件夹中。

3.配置~/vimrc

在~/.vim下创建文件vimrc

~/.vim$ vim vimrc

将以下内容复制到 vimrc中

filetype off
syntax on
set rtp+=~/.vim/bundle/Vundle.vim
call vundle#begin()
Plugin 'VundleVim/Vundle.vim'

4.安装插件

terminal中输入vim命令
```
~$ vim
```
进入到vim中后输入 :PluginInstall命令安装插件

安装完成，如下如图所示
5.自动补全插件YouCompleteMe的配置
进行到这一步，vim基本已经配置差不多啦，最后来进行自动补全的配置。
此时打开vim底部会出现YCM的报错，现在来解决。
1. 安装python3、python3-dev
```
~$ sudo apt install python3 python3-dev
```
1. 执行如下命令(使用绝对路径)
```
~$ /usr/bin/python3 ~/.vim/bundle/YouCompleteMe/install.py --all --verbose
```
