getting sfwecho serviceFrameWork example to work

[topquarck]

hi there;

I'am trying to learn QtMobility's serviceFrameWork on Symbian. I found the sfwecho example on Qt's repository:
http://qt.gitorious.org/qt-mobility/...amples/sfwecho
I tried to run it But it gives me the following errors:

main.cpp:: error: undefined reference to `QtMobility::QRemoteServiceClassRegister::registerType(QMetaObject const*, QObject* (*)(), QtMobility::QRemoteServiceIdentifier (*)(), QtMobility::QRemoteServiceClassRegister::InstanceType)'

main.cpp:: error: undefined reference to `QtMobility::QRemoteServiceClassRegister::registerType(QMetaObject const*, QObject* (*)(), QtMobility::QRemoteServiceIdentifier (*)(), QtMobility::QRemoteServiceClassRegister::InstanceType)'

main.cpp:: error: undefined reference to `QtMobility::QRemoteServiceControl::QRemoteServiceControl(QObject*)'

main.cpp:: error: undefined reference to `QtMobility::QRemoteServiceControl::publishServices(QString const&)'

although, the QRemoteServiceControl.h file exists in the src/ folder of the qtmobility folder I downloaded from the gitorious repo, along with the example code itself.
I'm using Nokia Qt SDK 1.0.0.2 , Qt 4.7.0 and Qtcreator 2.0.1

thanks in advance;
