They are just warning messages. Examples run fine. I think this virtual
destructor warning is something new with g++ 4.0 and I am using 4.0.1.
I went to the qt-interest mail list, as suggested in another reply, and there
were several discussions concerning this problem. For now I will enter
QMAKE_CXXFLAGS_WARN_ON += -Wno-non-virtual-dtor
in each .pro file to silence the warning.
Thanks, Mike
