안녕하세요...
 만 하루가 채 안되어 다시 질문을 올립니다..
 이자리를 빌어 지난번 고마운 답변을 주신 조준기님께 감사의 말씀을 드립니다.
 실은 그 답변에 대한 질문입니다.
 지난번 LD_LIBRARY_PATH문제를 지적해 주셨는데 바로 그 문제가 발생하고 있습니다.
 즉 /usr/lib이외에는 라이브러리화일(*.a, *.so)를 넣어도 찾지 못한다는 사실입니다.
 /$ORACLE_HOME/lib에 있는 라이브러리도 전혀 읽지 못하고, /usr/lib에
 복사해 주었을때만 인식을 하고 넘어갑니다.
 일단 이 문제는 이렇고, make에 대해서 하나 더 여쭙겠습니다.
 make -f demo_proc.mk sample1 요렇게 해주는 부분입니다.
 여기서도 각종 헤더파일들을 찾습니다만(ex. stdio.h, stdarg.h등) 의 파일이 여러군데
 존재하는데, 어떤 파일인지도 잘 모르겠고 임의로 하나를 정해주면 아래와 같은
 알도 못하겠는 에러가 나는 겁니다.
 물론 echo $LD_LIBRARY_PATH도 잘 나오고, ldconfig도 실행하였습니다. 물론 ld.so.conf
 역시 수정해 주었구요...
 Oracle배우기 힘이 드는 군요... 근데다가 일은 당장 눈앞에 떨어졌으니...
 참, 눈앞이 깜깜합니다.
