Use Gtags__vim in VIM

Download Global on the website download global source

Http://www.gnu.org/software/global/download.html

Compile and install Global./configure
Make sudo make install

Gtags vim script configures copy global source directory to Gtags-cscope.vim,gtags.vim to. Vim directory, I use Neobundle management plugin

The. VIMRC is configured as follows,

You can automatically choose to load index database files in Cscope.out and Gtags.

The script will first detect if the Gtags file exists,

If it does not exist, find cscope.out,

"Gtags-cscope setting {{" I use the GNU global instead cscope because global is faster.
