Symbian Project Errors when Mobility Added
-
I have created a Symbian project that compiles and runs flawlessly on my C7. However, I wanted to add the QOrientationSensor to the project so I could tell when to reformat the screen by signals from the sensors.
my current .pro file :

@I am attempting to add the *Screen orientation detection for QML * from
Chris' Blog - cdumez.blogspot.com/2010/12/screen-orientation-detection-for-qml.htmlThe result is errors that indicate QtMobility is not in the namespace even though I have used the QTM_USE_NAMESPACE macro and mobility global header.
Here are the errors from QtCreator:

@Mobility libs are in the path of the project.
Can someone point me in the right direction?Environment is:
Ubuntu 11.04
KERNEL 2.6.38.10-generic
GNOME 2.32.1latest update of Qt SDK 1.2 as of 14 July 2011
P.S. same results with WinXP QtSDK as well.

Hey ad5xj,
your .pro file looks fine (as in, looks like the one I use and works).In Ubuntu, are you using the Remote compiler for symbian?
How did you install QtMobility? Following this:
https://projects.developer.nokia.com/QtM12bSymb/wiki/InstallationGuide ?I'd say your problem is either on the sdk/mobilit installation or on your actual code.
-
The QtMobility module was installed by the SDK maintainer. I did not install it manually either on Linux or WinXP.
I can find no reason - code wise - why I should be getting this error.
The QTM_USE_NAMESPACE macro should resolve this kind of thing but it does not.
On Linux I do not use the remote compiler. I used the gcc compiler for the simulator which should work. On WinXP I use mingw.
-
Ah ok. Yes, it should work fine on the simulator.
Are your orientation.[cpp,h] the same from the ones in the chris's blog post? There he's not using QTM_USE_NAMESPACE because he's explicitly using "QtMobility::"
The QTM_USE_NAMESPACE macro is only defined as "using namespace QtMobility;" -
Well it looks like I spoke too soon. Now the compiler indicates the macro does not name a type:

Yes. I have included the Mobility global header in the orientation.cpp module. That avoids the QOrientationReading errors above. I just had a typo. (sorry)
For some reason, no matter what I do QML is not recognising the new module.
using Chris's method:
main.cpp
context->setContextProperty("Orientation", new Orientation(&app;));
I get this error:
ReferenceError: Can't find variable: OrientationIf I do it a different way:
orientation.h
Q_DECLARATIVE_EXPORT class Orientation : public QObject
{}main.cpp:
qmlRegisterType<Orientation>("Orientation", 1, 0, "Orientation");main.qml:
import Orientation 1.0;I only get this error:
module "Orientation" is not installedFrustrating!
I am missing something but I cannot for the life of me figure what it is.
Well using both Linux and WinXP installations helps.
When I booted into windows and ran the same code, I got this error:
ReferenceError: Can't find variable: Orientation

loaded the Generic pluginI am running in release mode so this does not make sense. Maybe the makespecs do not point to the right plugin?

[/quote]I just noticed this same problem, latest Qt SDK on Win7. Even more bizarrely, running in debug mode I get a similar error message, but then it tries to load the release version of the sensors plugin.
