(CONFIG += release) right ?
You need to reconfigure and rebuild Qt using > ./configure -release and if you're going to be using that Qt together with Jambi I strongly suggest you to put "-no-mmx -no-sse -no-sse2 -no-3dnow" on the configure line as well, as java has a bug in 1.5 where it doesn't properly align the C stack before entering native code, causing mmx operations to crash. _______________________________________________ Qt-jambi-interest mailing list [email protected] http://lists.trolltech.com/mailman/listinfo/qt-jambi-interest
