Vundle插件管理器

1 下载vundle

git clone https://github.com/gmarik/vundle.git ~/.vim/bundle/vundle

2 配置.vimrc

set nocompatible              " be iMproved, required
filetype off                  " required

" set the runtime path to include Vundle and initialize
set rtp+=~/.vim/bundle/Vundle.vim
call vundle#begin()
Plugin 'VundleVim/Vundle.vim'

" Keep Plugin commands between vundle#begin/end.
call vundle#end()            " required
filetype plugin indent on    " required

vim基本配置

从vim的default.vim中修改的

set nocompatible
set backspace=indent,eol,start  "Allow backspacing over everything in insert mode.
set history=200        " keep 200 lines of command line history
set ruler        " show the cursor position all the time
set showcmd        " display incomplete commands
set wildmenu        " display completion matches in a status line
set hlsearch            " hightlight searched phase
set ttimeout        " time out for key codes
set ttimeoutlen=100    " wait up to 100ms after Esc for special key
set display=truncate    " Show @@@ in the last line if it is truncated.
set scrolloff=5         "Show a few lines of context around the cursor
set incsearch           " Do incremental searching when it's possible to timeout.
set mouse=a
set number
set expandtab
set tabstop=4
set shiftwidth=4
set softtabstop=4

  " mapping.  If set (default), this may break plugins (but it's backward
  " compatible).
  set nolangremap
endif

YouCompleteMe

vundlle管理YCM，在.vimrc相应位置加上Plugin 'Valloric/YouCompleteMe'
打开vim，运行:PluginInstall，安装插件
进入~/.vim/bundle/YouCompleteMe/，运行./install.py（--clang-completer支持C系列语言补全，需要安装llvm+clang）

可能需要注意：

vim python support
git用来下载YCM的问题
cmake默认编译器的问题（export CC和CXX到高版本的编译器）
