Original title: "usage of "QtMobility::" in code gives error "undefined reference to `_imp___ZN10QtMobility15QContactManagerC1ERK7QStringRK4QMapIS1_S1_EP7QObject' and"

Can you guess what is wrong in my installation of QtCreator?

Note that if I remove usage of QtMobility namespace, errors goes away!

Here is pro file:

do you link to the QtMobility libs?
I don't see so....

What do you mean by "remove usage of QtMobility namespace"? Can you show us some sample code? As far as I know there is no namespace involved with Qt Mobility.

Add this to your project file:
@MOBILITY = contacts@

After reading the docs I must admit that this is wrong. Qt Mobility does use namespaces, sorry for any inconvenience.

Why should Qt Creator be wrong when you can not link to some random library? Most likely your project's build system is broken since it does not link to the libraries your code needs.

Thanks, Adding contacts to MOBILITY worked and I am able to run it on simulator, but now, I have another problem.

If I try to build same project (which works fine on simulator) for symbian, it does not successfully build with errors stating that QtMobility namespace and classes are not found!

Do I need to do something else? I noted that C:\NokiaQtSDK\Symbian\SDK\include has QtContacts directory but it does not contain .h files...

Any help is appreciated.

You might want to try the new Qt SDK 1.1. Technology Preview. It should contain QtMobility 1.1 for Symbian targets. http://labs.qt.nokia.com/2011/01/20/qt-sdk-1-1-technology-preview-released/
