Please post your code and the complete error.
The line you posted only states that there is an error in main.o, but not what the error is.

That code looks ok (at first sight).

Can you post the complete error please?
I guess it's a linker error which means it might be possible that certain components can't be found.

If you use Qt Creator, the complete error can be found in the compile or build tab at the bottom.

As far as I know, the book was written before Qt Creator was released.
But you can find information on this page: http://doc.qt.nokia.com/qtcreator-2.0/index.html
