（一）首先编辑~/下的.vimrc

" An example for a vimrc file.

"	      for Amiga:  s:.vimrc
"  for MS-DOS and Win32:  $VIM_vimrc
"	    for OpenVMS:  sys$login:.vimrc

" When started as "evim", evim.vim will already have done these settings.

" This must be first, because it changes other options as a side effect.

" CTRL-U in insert mode deletes a lot.  Use CTRL-G u to first break undo,

set termencoding=utf-8
set fileformats=unix
set encoding=prc

（二）然后安装ctags 和cscope （我用的是ubuntu，所以#sudo apt-get install 就搞定了）

（三）在写代码的目录下运行

ctags -R
cscope -Rbq

（四）在vi中运行

:set tag=xxx/tags
:cs add xxx/cscope.out  xxx/

（五）现在你就能在代码中各种跳了
C_- c 查找调用函数的地方
C_- g 查找函数定义的地方
C_- c 是 CTRL +shift + - 然后快速按c
ctrl+] 跳到函数定义的地方
wm 打开taglist 和FileExplorer

效果图
