compiling a simple program with qt
I followed the directions at http://doc.trolltech.com/4.1/tutorial-t1.html to try to compile the example there called main.cpp. I have libqt3-mt. I just installed libqt2-mt-dev and all of the dependencies it needs. I do not know why I am getting these errors. What should I do?
