1, cscope安装
1. 软件下载：
解压：
第一步：bzip2 -d gcc-4.1.0.tar.bz2
---上面解压完之后执行下面的命令。 第二步：tar -xvf gcc-4.1.0.tar 或 tar -xvf *.tar 解完之后会出现多一个文件夹 gcc-4.1.0 2. 软件安装: 1. ./configure --with-flex (注：如果平台是Linux,最好带上 --with-flex选项) 2. make (注：我没有遇到错误) 3. make install (注： 直接安装好了) 2,cscope配置 1. 修改vim配置文件vimrc.你可以修改/etc/vimrc使用所有用户都使用本配置文件，当然你还可以修改~/.vimrc 1. 下载配置文件：cscope_map.vim""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""" CSCOPE settings for vim """""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""" This file contains some boilerplate settings for vim's cscope interface," plus some keyboard mappings that I've found useful.""

" If you don't like using 'CTRL-@' or CTRL-\, , you can change some or all " of these maps to use other keys. One likely candidate is 'CTRL-_' " (which also maps to CTRL-/, which is easier to type). By default it is " used to switch between Hebrew and English keyboard mode. " " All of the maps involving the macro use '^ $': this is so " that searches over '#include " return only references to " 'time.h', and not 'sys/time.h', etc. (by default cscope will return all " files that contain 'time.h' as part of their name). " To do the first type of search, hit 'CTRL-\', followed by one of the " cscope search types above (s,g,c,t,e,f,i,d). The result of your cscope " search will be displayed in the current window.

" "set ttimeout " " personally, I find a tenth of a second to work well for key code " timeouts. If you experience problems and have a slow terminal or network " connection, set it higher.

R 表示把所有子目录里的文件也建立索引 3. b 表示cscope不启动自带的用户界面，而仅仅建立符号数据库 4. q生成cscope.in.out和cscope.po.out文件，加快cscope的索引速度 5. k在生成索引文件时，不搜索/usr/include目录 2. 在源码根目录下打开任意.c文件，使用如下命令： 1. Ctrl+]将跳到光标所在变量或函数的定义处 Ctrl+T返回 2. ：cs find s ---- 查找C语言符号，即查找函数名、宏、枚举值等出现的地方 ：cs find g ---- 查找函数、宏、枚举等定义的位置，类似ctags所提供的功能 ：cs find d ---- 查找本函数调用的函数 ：cs find c ---- 查找调用本函数的函数 ：cs find t: ---- 查找指定的字符串 ：cs find e ---- 查找egrep模式，相当于egrep功能，但查找速度快多了 ：cs find f ---- 查找并打开文件，类似vim的find功能 ：cs find i ---- 查找包含本文件的文 3. 2的所以命令也可以且按銉来实现： 1. Ctrl+\\ 再按 s 表示：cs find s命令 2. 同理实现cs find + g,d,c,t,e,f,i命令 3. cscope_map.vim说明： 1. 有英文注释的我就不说明了，我就说一下里边的键map映射 2. 如： nmap <C-\\>s :cs find s <C-R>=expand("<cword>")<CR><CR> 1. nmap 表示在vim的普通模式下，即相对于：编辑模块和可视模式，以下是几种模式 1. :map 普通，可视模式及操作符等待模式 :vmap 可视模式 :omap 操作符等待模式 :map! 插入和命令行模式 :imap 插入模式 :cmap 命令行模式 2. <C-\\>表示：Ctrl+\\ 3. s表示输入(即按：s)s 4. : 表示输入\':\' 5. “cs find s"表示输入"cs find s"也即是要输入的命令 6. <C-R>=expand("cword")总体是为了得到：光标下的变量或函数。cword 表示：cursor word, 类似的还有：cfile表示光标所在处的文件名吧 7. ＜CR＞＜CR＞就是回车吧，不太清楚
