Hi! I noticed that you and Kassen replied to my question about building miniAudicle (for some reason, they weren't included in the daily digest). I don't think the problem is the wrong version of qt. I installed all the dependencies (at least the ones that are mentioned in the installation instructions), and I believe I have qt 4 installed correctly. I installed all the packages below: Full list of required packages ------------------------------ These are the packages which, along with each package's subdependencies, are required to build miniAudicle on current Ubuntu systems; on other Linux systems these packages likely exist with the same or similar names. make gcc g++ bison flex libasound2-dev libsndfile1-dev libqt4-dev libqscintilla2-dev libpulse-dev (linux-pulse only) libjack-jackd2-dev (linux-jack only) The only reason I mentioned qt 3 was that I saw some references to differences between qt3 and qt4 when I googled the error message. Doesn't the error message indicate that I have qt4 installed? *qmake-qt4* "RTAUDIO_BACKEND=ALSA" -o makefile.qt-alsa miniAudicle.pro uic: Error in line 51, column 41 : Unexpected attribute alignment uic: Error in line 189, column 41 : Unexpected attribute alignment Isn't 'qmake-qt4' part of qt4? I'll check again when I get home, though. Thanks.
