gdb stl의 list나 vector등 값 까보기

원글(이글루): 2010-06-11 18:05:47

gdb에서 define으로 함수처럼 정의해 쓸수있다.

첨부는 STL의 list나 vector등의 값을 따라 갈때 편리하게 하기 위해서 만들어 놓은 것이다.

원본은 plist가 하나의 함수로 되어 있는데, gdb버전이 낮은 경우 argc라는 변수가 없다.
그래서 인자 갯수별로 plist1 , plist2 이런식으로 함수 분리하는 작업을 한 파일도 첨부한다.

~/.gdbinit 파일을 첨부파일로 대체하면 된다.
개인적으론
“set print pretty on” 를 주석처리하는게 한줄에 나오고 더 좋은거 같다.
