Download the source code to the http://ctags.sourceforge.net, unzip
　
$./Configure
　
$ Make
　
$ Sudo make install

$ Ctags-R
　
"-R" indicates recursive creation, that is, the source code under all subdirectories under the source code root directory. The tags index file is generated under the current directory.
　
Assume that the current source code directory contains the following content:
　
. /Makefile
　
. /Src # source code folder
　
After ctags-R is executed
　
. /Makefile
　
. /Src # source code folder
　
. /Tags
　
The "tags" file contains a list of these objects:

3. vim will use the index in the tags file to locate
　
Run vim in the directory where the tags file is located to open the source file. C or. H
　
A. move the cursor to the position of the variable or function to be viewed. Press ctrl +] to jump to the position defined by the variable or function, and press ctrl + o to return.
