qt 프로그래밍 질문입니다.

이제 막 Qt를 공부하려고 합니다.
Qt는 Fedora4를 인스톨시 바로 깔았습니다.

[root@watch mkspecs]# rpm -qa qt*
qt-designer-3.3.4-14
qt-devel-3.3.4-14
qt-3.3.4-14

hello world 프로그램의 코드를 작성하고
[styner@watch qt]$ qmake -project
[styner@watch qt]$ qmake
[styner@watch qt]$ make

하였더니, 다음과 같은 에러가 발생합니다.

이곳 저곳을 찾아보니, 소스는 single thread용인데 시스템에는 multi thread용 qt라이브러리 밖에 없어서
그렇다고 합니다...

project 파일의 CONFIG에 thread를 추가해주면 된다던데...아직 해결하지 못하고 있습니다.

혹시 비슷한 문제를 겪으셨던 분은 답변 부탁드립니다.
감사합니다.
