> Oooops... > link against qt-mt (thread-support), and not qt, solved that very nicely Could anyone clue me in as to why there are qt libraries without mt and qt-mt ? I seem to be experiencing some kind of mix-and-matching (I tried to compile ecawave with libqt3 and it gave me warnings that some plugins were compiled with thread support and ecawave wasn't, and I tried linking with libqt3-mt, and the warning was gone.) regards, junichi
