Problem compiling Qt example from OS X terminal

I'm currently learning Qt by working through examples in the ebook "C+ GUI Programming with Qt 4, Second Edition".

The first example is a "Hello World" application. Following the steps in the example I've been able to create the following files:

However, I am unable to create "hello.app"

The command "make" yields: 

"make: *** No targets specified and no makefile found.  Stop."

The command "make hello" yields:

g++     hello.cpp   -o hello
hello.cpp:1:24: error: QApplication: No such file or directory
hello.cpp:2:18: error: QLabel: No such file or directory
hello.cpp: In function ‘int main(int, char**)’:
hello.cpp:6: error: ‘QApplication’ was not declared in this scope
hello.cpp:6: error: expected `;' before ‘app’
hello.cpp:7: error: ‘QLabel’ was not declared in this scope
hello.cpp:7: error: ‘label’ was not declared in this scope
hello.cpp:7: error: expected type-specifier before ‘QLabel’
hello.cpp:7: error: expected `;' before ‘QLabel’
hello.cpp:9: error: ‘app’ was not declared in this scope
make: *** [hello] Error 1

While I can't create "hello.app" from the terminal with these two commands, I can create it by simply opening Xcode and pressing the button "Build and Go".

Can someone tell me why in the world these two commands don't work? And how I can make the "hello.app" from the terminal?

Thanks!

I would suggest you download and install Qt SDK. Then familiar yourself with Qt Creator, the IDE for Qt. It's much easier that way since all the frameworks and docs are installed and configured for you.

I see that qmake has generated an *.xcodeproj-file for you. Try running xcodebuild instead of make :)

It looks like you didn't include the directories from the Qt SDK in your makefile paths. Did you also remember to run QMake?
