gdb를 쓰기위한 -g 옵션이 먹지 않습니다 ㅠㅠ

제가 어떤 소스를 받아서 컴파일 할때 -g 옵션을 주어 DDD(data display debugger)에서 소스를 보려고 합니다. 근데 -g옵션을 주어 DDD로 실행파일을 열면 "no debugging symbols found)라고 나옵니다.물론 GDB에서도 증상은 같습니다
제가 알기로 -g가 안되면 소스레벨 디버깅이 안된다고 알고 있는데 해결책 없나요?? makefile 올릴테니 아시는 분 답변 부탁드립니다...
그리고 밑에 부분중에
set EXTRA_LIBS="-L. -L/usr/lib -lm" 과 set EXTRA_INCLUDES="-I."
의 의미를 가르쳐 주시면 감사하겠습니다. ㅠㅠ 교수님이 자꾸 쪼아서 아주 짱나 죽겠어요....ㅠㅠ
