cscope

sudo apt-get install cscope

I have the  cscope_maps.vim file(check turtoial [1]), and the .vimrc thing from Vim Tips Wiki [2], but removed the quick fix part, as suggested by the [3]. After removed the quick fix part, all duplicated symbol will ask for selection, even for tags!!!

cscope -Rbk -s XXXX
-R     Recurse subdirectories during search for source files.
-b     Build the cross-reference only.-q     Enable  fast  symbol  lookup  via an inverted index.
-k     ``Kernel Mode'', turns off the use of the  default  include  dir (usually  /usr/include) when building the database, since kernel source trees generally do not use it.
-sdir  Look in dir for additional source files. This option is  ignore if source files are given on the command line.
-q     Enable  fast  symbol  lookup  via an inverted index.

-C     Ignore letter case when searching.
-d     Do not update the cross-reference.
Cscope interactive
^d: Exit cscope.
: Alternate between the menu and the list of matching lines

Contrl-\+

Vi with Cscope
http://web.missouri.edu/~hantx/Tools/vi/TonyViNotes/node11.html
  1. Building database for Cscope:
    $ cscope -Rb
    This command makes the Cscope parse all the subdirectories (-R option) and exit without entering awkward Cscope interface.
  2. List all the uses of the symbol under the cursor:
    Ctrl+\s
    That is Control-backslash and then 's'. Select one of items in the list and hit enter, you will jump to the that use. Ctrl+t jump back.
  3. Find functions that under the cursor
    Ctrl+\d
    That is Control-backslash and then 'd'.
  4. Open the file with filename under cursor
    Ctrl+\f
    That is Control-backslash and then 'f'.
  5. Jump back from most recent jumping-off point:
    Ctrl+t
