這以 GNU GLOBAL 6.5.6 為示範

 

1:

install GNU GLOBAL

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

sudo ./configure;

若有以下 error,請看更下方的 Q5 說明。

configure: checking "location of ncurses.h file"...
configure: error: curses library is required but not found.
If you are not going to use gtags-cscope, please try ./configure --disable-gtagscscope

 

sudo make;

sudo make install

----------------------------------------------------------------------------------------------------

Q5. What is the message? What should I do?

‘configure: error: curses library is required but not found."

 

A5. gtags-cscope(1) requires curses library. There are two choices of yours.

             If you use gtags-cscope(1)

                       Please install curses library. You can get it here:

                       http://www.gnu.org/software/ncurses/

             else

                       You can install GLOBAL without gtags-cscope(1) like follows:

                       $ ./configure --disable-gtagscscope

                       $ make

因為這裡要使用 gtags-cscope,

所以要 install curses library. 參考下方

-------------------------------------------------------------------------------------------------------

 

 

2:

install curses library

http://www.gnu.org/software/ncurses/

sudo ./configure; sudo make; sudo make install;

 

 

3 :

install vundle

https://github.com/VundleVim/Vundle.vim

sudo apt-get install git curl

git clone https://github.com/VundleVim/Vundle.vim.git ~/.vim/bundle/Vundle.vim

請看 https://github.com/VundleVim/Vundle.vim 的 Quick Start 的 第3步驟 Configure Plugins:

 

 

4 :

以下要依照 user 當時所安裝的 gnu global 版本,plugin 對應版本的 gtags.vim、gtags-cscope.vim,

可以下載 gnu global source code,裡面就有對應版本的 gtags.vim、gtags-cscope.vim

或是在網路上搜尋對應版本的 gtags.vim,gtags-cscope.vim 並使用以下的 Vundle plugin 方式

Plugin bbchung/gtags.vim
Plugin multilobyte/gtags-cscope

 

 

5:

在您要 tag 的 source code 的資料夾下,

執行

gtags

 

 

6:

假如您在 source code 找一個定義,

:cs find g the_definition_you_want_find

若出現以下訊息

E567: no cscope connections

需在 ~/.vimrc 加入以下

let g:GtagsCscope_Auto_Load = 1

 

若需要使用 cscope 的快捷鍵,       ===〉  注意,VirtualBox 4.3.36 無法使用組合鍵,如 ctrl 加上 \ 再加上 s

快捷鍵在 gtags-cscope.vim 有說明,

需在 ~/.vimrc 加入以下 code 。

let g:GtagsCscope_Auto_Map = 1

 

cscope command

 54 "       explanation             command 
 55 "       ----------------------------------------------------------
 56 "       Find symbol             :cs find 0 or s
 57 "       Find definition         :cs find 1 or g
 58 "       Find functions called by this function  (not implemented)
 59 "       Find reference          :cs find 3 or c
 60 "       Find text string        :cs find 4 or t
 61 "       Find egrep pattern      :cs find 6 or e
 62 "       Find path               :cs find 7 or f   ===>  跳至 include 的 file。如:#include "t.h",跳至 t.h
 63 "       Find include file       :cs find 8 or i   ===>  找尋有那些 source code 有 include 這個 文件。 如: a.c b.c 都有 include "c.h"

 

快捷鍵

ctrl + \ + s | g | c | t | e | f | i

232             " normal command
233             :nmap <C-\>s :cs find s <C-R>=expand("<cword>")<CR><CR>
234             :nmap <C-\>g :cs find g <C-R>=expand("<cword>")<CR><CR>
235             :nmap <C-\>c :cs find c <C-R>=expand("<cword>")<CR><CR>
236             :nmap <C-\>t :cs find t <C-R>=expand("<cword>")<CR><CR>
237             :nmap <C-\>e :cs find e <C-R>=expand("<cword>")<CR><CR>
238             :nmap <C-\>f :cs find f <C-R>=expand("<cfile>")<CR><CR>
239             :nmap <C-\>i :cs find i <C-R>=expand("<cfile>")<CR><CR>
