1.安装ctags+cscope

2.下载vim插件 Source Explorer/NERD Tree/Tag List

网址：www.vim.org Scrips-->Bowse all -->在keyword中搜索上述三个插件并下载解压到~/.vim文件夹下

3.vim 配置

打开vim配置文件，（ubuntu是在/etc/vim/vimrc中），在最后添加如下内容：

"------------------------------------------""vim env setting""------------------------------------------"    set nu  "display line number"    set ai  "auto indent"    set ts=4    "tab size"    set bg=dark "blackground color"    filetype plugin on"------------------------------------------""ctags database setting""------------------------------------------"    set tags=/home/software/linux-3.8.3/tags     "ctags DB position 根据自己的文件路劲进行修改""------------------------------------------""ctags database setting""------------------------------------------"    set csprg=/usr/bin/cscope    "cscope install position"    set csto=0                   "cscope DB search first"    set cst                      "cscope DB tag DB search"    set nocsverb                 "verbose off"    cs add /home/software/linux-3.8.3/cscope.out       /home/software/linux-3.8.3   "根据自己的文件路径进行修改"    set csverb     "------------------------------------------""Tap List env setting""------------------------------------------"   filetype on   nmap <F7> :TlistToggle<CR>   let Tlist_Ctags_Cmd = "/usr/bin/ctags"   let Tlist_Inc_Winwidth = 0   let Tlist_Exit_OnlyWindow = 0   let Tlist_Auto_Open = 0   let Tlist_Use_Right_Window = 1"------------------------------------------""Source explorer env setting""------------------------------------------"    nmap <F8> :SrcExplToggle<CR>    nmap <C-H> <C-W>h    nmap <C-J> <C-W>j    nmap <C-K> <C-W>k    nmap <C-L> <C-W>l    let g:SrcExpl_WinHeight = 8    let g:SrcExpl_refreshTime = 100    let g:SrcExpl_jumpkey = "<ENTER>"    let g:SrcExpl_gobackKey = "<SPACE>"    let g:SrcExpl_isUpdateTags = 0"------------------------------------------""NERD Tree env setting""------------------------------------------"    let NERDTreeWinPos = "left"    nmap <F9> :NERDTreeToggle<CR>" Open and close all the three plugins on the same time"nmap <F8>   :TrinityToggleAll<CR>" Open and close the srcexpl.vim separately"nmap <F9>   :TrinityToggleSourceExplorer<CR>" Open and close the taglist.vim separately"nmap <F10>  :TrinityToggleTagList<CR>" Open and close the NERD_tree.vim separately"nmap <F11>  :TrinityToggleNERDTree<CR>" -----------------------------------------------------------------------------"  < 编写文件时的配置 >" -----------------------------------------------------------------------------filetype on                                           "启用文件类型侦测filetype plugin on                                    "针对不同的文件类型加载对应的插件filetype plugin indent on                             "启用缩进set smartindent                                       "启用智能对齐方式set expandtab                                         "将Tab键转换为空格set tabstop=4                                         "设置Tab键的宽度，可以更改，如：宽度为2set shiftwidth=4                                      "换行时自动缩进宽度，可更改（宽度同tabstop）set smarttab                                          "指定按一次backspace就删除shiftwidth宽度set foldenable                                        "启用折叠"set foldmethod=indent                                 "indent 折叠方式" 常规模式下用空格键来开关光标行所在折叠（注：zR 展开所有折叠，zM 关闭所有折叠）nnoremap <space> @=((foldclosed(line('.')) < 0) ?
