Running Qt 4.7 apps on Symbian^3

[liz_steel]

I am using Carbide (version 2.3.0) to build and am trying to run the example apps given with Qt 4.7.0.

Every app I run gets a KERN-EXEC 3 error on startup. I've tried the demos, and the mainwindows example app, plus I've also tried creating a blank main window project and running that.

Any ideas?

Thanks.

Does this mean I can't run Qt 4.7.0 on Symbian^3?

Should I use Qt 4.6.3 instead?

Are you launching your applications on the phone or in simulator? Naturally Symbian^3 supports Qt 4.7.x, but your testing environment seems not.

Did you try to install the Qt Installer sis which came in the /qtXXX/ folder?

I am launching the emulator (from Carbide). We do have an N8, but it is currently not working, so I can't test on that at the moment.

I will revert back to 4.6.3 until 4.7 is more stable.

Thanks,
Liz.

Qt 4.7 is stable.

[vladest]

even revisions never stable

OK, I've installed Qt 4.6.3 now (still using Symbian^3) and I'm getting the same problem.

I create a Qt GUI Main Window project, it builds fine, but when I run it I get a KERN-EXEC 3 error when it tries to create the status bar.

This is the auto-generated code:

    void setupUi(QMainWindow *TestingQt)
    {
        if (TestingQt->objectName().isEmpty())
            TestingQt->setObjectName(QString::fromUtf8("TestingQt"));
        TestingQt->resize(800, 600);
        centralwidget = new QWidget(TestingQt);
        centralwidget->setObjectName(QString::fromUtf8("centralwidget"));
        TestingQt->setCentralWidget(centralwidget);
        menubar = new QMenuBar(TestingQt);
        menubar->setObjectName(QString::fromUtf8("menubar"));
        menubar->setGeometry(QRect(0, 0, 800, 21));
        TestingQt->setMenuBar(menubar);
        statusbar = new QStatusBar(TestingQt); // Crash here
        statusbar->setObjectName(QString::fromUtf8("statusbar"));
        TestingQt->setStatusBar(statusbar);

        retranslateUi(TestingQt);

        QMetaObject::connectSlotsByName(TestingQt);
    } // setupUi

Has anyone successfully run a Qt app on Symbian^3? Is there something extra that I need to do to get it working?

Thanks,
Liz.

Take the problem to the source and ye shall receive.

Official from a bug report:

This is I believe because of bug QTBUG-13831 as you are not installing it on C: drive. However, even if you were to install it to C: drive, it wouldn't work as the qt_installer.sis and qt_demos.sis that come with Qt for Symbian (S60) 4.7.0 package are not compatible with N8; those packages are meant only for S60 3.x and 5.0 devices. Since N8 has Qt already preinstalled on the device, updating it will be done via same channels are other phone software.

So there is not much we can do now. Re 4.7: IMHO it is a LOT better than 4.6.3 was. even though the UI worked better in 4.6.2 still, but I am working on that by reporting bug reports en masse

Hi, thanks for the reply, but I don't think this answers my question. This bug seems to be about installing the sis file to the memory card on a phone - I'm trying to build and run a Qt application on the Symbian^3 emulator.

I removed the status bar, and it runs OK, but as soon as I add anything else to the app (e.g. a button or a menu item) I get the same problem.

Is there anyone out there who has managed to get Qt building and running with Symbain^3?

Thanks,
Liz.

AFAIK, QT 4.7 currently is NOT permitted for Symbian^3. What I was told, this CAN NOT be deployed as of this writing.

If you manage to get Qt 4.7 up and running, you are farther than Nokia wanted you to go.

Sorry, but this is how it is. I am not responsible for it and can but ask for understanding

[liz_steel]

Right, I've tried a different route now.

I've installed the latest version of Symbian^3, which has Qt already installed in it. (Version 0.9)

I'm using Carbide (2.6.0), and I can create a dummy app, however, when I try to build the app, I get the following error:

process_begin: CreateProcess((null), \epoc32\tools\uic QtTestingOnCarbide.ui -o ui_QtTestingOnCarbide.h, ...) failed.
make (e=3): The system cannot find the path specified.

make[2]: *** [ui_QtTestingOnCarbide.h] Error 3

I've managed to run uic on a command line successfully - it seems that the build process is trying to use "/epoc32/tools/uic" rather than just "uic" - how do I change this?

[tamhanna]

Maybe set a link on OS level? There IMHO is a program for WIndowes which can do this...if you want me, I can look it up for you!
