Compile Errors

[luffy27]

I downloaded a app which is a simple calculator. But when I try to compile it and run it on my own machine there showed many errors.
And the way i compile the app is :
1. qmake -project
2. qmake
3. make
My Qt version is 3.3.3. I don't know where is the problem or what is the right way to compile and run the app. I be totally a fresh man with Qt.
please HELP me .Thanks.

You are using Qt 3.3.3 but the code is for Qt 4 and that is why you are getting the errors
