* ctags 만으로는 지역변수나 전역변수 함수가 사용된 곳은 찾기 힘들때 사용.

1. cscope 다운받기 ( ex : apt-get install cscope )

2. mkcscope.sh 파일 작성
=======================================================================================
#!/bin/sh
rm -rf cscope.files cscope.files

find . \( -name '*.c' -o -name '*.cpp' -o -name '*.cc' -o -name '*.h' -o -name '*.s' -o -name '*.S' \) -print > cscope.files

cscope -i cscope.files
=========================================================================================
 
chmod 755 mkcscope.sh

mv mkcscope.sh /usr/local/bin

명령어를 입력한 후 소스, 헤더 파일이 있는곳으로 가서 (include or linux-2.4) mkcscope.sh 를 실행

cscope.out 파일이 생성됨.

.vimrc 에 추가할 내용
=========================================================================================

"===============  cscope 설정 =========================
set csprg=/usr/bin/cscope
set csto=0
set cst
set nocsverb

if filereadable("./cscope.out")
        cs add cscope.out
else
        cs add /usr/include/cscope.out
endif
set csverb

* .vimrc 에 cscope 단축키 관련 추가
