Joel, At any case, try last version. The app has little page now: http://gaydenko.com/qloud/ As for Qwt, you have specidied lib dir, rather the lib itself. Try add '-lqwt' along with other (-ljack -lfftw3 and so on).

Qwt is compiled from CVS and src.pro is : LIBS += -L/home/moa/sources/qwt/lib \ -ljack \ -lfftw3 \ -lsndfile INCLUDEPATH += ../src \ /home/moa/sources/qwt/include \ /usr/include MOC_DIR = ../moc UI_DIR = ../ui OBJECTS_DIR = ../obj TARGET = ../bin/qloud QT += xml CONFIG += debug \ warn_on \ qt \ thread \ exceptions \ console TEMPLATE = app What do I miss? joel
