    Linking problems trying to compile QT application

    Guys im trying to do the exercise of http://doc.trolltech.com/4.0/tutorial-t1.html
    but im stuck with the following errors:
    Code:
    g++ -c -pipe -Wall -W -O2 -march=athlon-xp -pipe -DQT_NO_DEBUG  -I/usr/qt/3/mkspecs/linux-g++ -I. -I. -I/usr/qt/3/include -o exercise1.o exercise1.cpp
    exercise1.cpp:7:28: QApplication: No such file or directory
    exercise1.cpp:8:27: QPushButton: No such file or directory
    exercise1.cpp: In function `int main(int, char**)':
    exercise1.cpp:12: error: `QApplication' undeclared (first use this function)
    exercise1.cpp:12: error: (Each undeclared identifier is reported only once for
       each function it appears in.)
    exercise1.cpp:12: error: parse error before `(' token
    exercise1.cpp:14: error: `QPushButton' undeclared (first use this function)
    exercise1.cpp:15: error: `hello' undeclared (first use this function)
    exercise1.cpp:18: error: `app' undeclared (first use this function)
    exercise1.cpp:11: warning: unused parameter `int argc'
    exercise1.cpp:11: warning: unused parameter `char**argv'
    exercise1.cpp:19:6: warning: no newline at end of file
    make: *** [exercise1.o] Error 1
    it is not finding the includes but they are there where the path points any ideas?
