    Re: Qt for Symbian development resources

    If you compile your Qt DLL for ARMV5, and may experience the following error:

    Error: C0000U: Unrecognized option '--visibility_inlines_hidden'.
    make[2]: *** [\Symbian\S60_5th_Edition_SDK_v1.0\EPOC32\BUILD\Qt\handon\CallEvent
    s_v2\LineStatus\LINESTATUSWATCHER_0XECBC4055\ARMV5\urel\LineStatusWatcher.o] Error 1

    You may solve the problem by changing the compiler configuation setting. The detailed information can be found at:

    Re: Qt for Symbian development resources

    Open C 1.7 has been released for Qt development!

    http://www.forum.nokia.com/info/sw.n...K_Plug-In.html

    Please be noted that the Open C 1.7 does not work well with the latest Qt 4.6.2 release at the time of this writing. Please download the Open C 1.6 instead

    Nokia Qt SDK: Cross-platform development made easy

    The Qt development framework enables C++ developers to deliver rich, cross-platform applications more easily than ever before. Now the revolution is set to go further, with the release of the Nokia Qt SDK Beta. This intuitive environment enables you to work on your favourite desktop platform. There is no need to install complex platform SDKs, because the Nokia Qt SDK includes a Qt simulator for testing application quickly and compilers to build applications for Symbian and Maemo devices. With features such as on-device debugging support and a technology preview of Qt Quick (the declarative UI definition tool), you can start exploring how you will soon be able to get everything done in one place, quickly and efficiently.

    Re: Qt for Symbian development resources

    http://qt.gitorious.org/qt/pages/Qt462KnownIssues

    Known issues Qt 4.6.2
    Symbian
    Also see common questions in SymbianFAQ.

    Compiling
    Qt libraries cannot be compiled with GCCE.

    Header inclusion like #include <QtTest> won’t work for RVCT. Use #include <QtTest/QtTest> instead.

    The wrapper makefiles created by qmake require GNU make to execute, the make.exe in the Symbian SDKs is sufficient for this. If you have an incompatible make.exe in your path (e.g. the one installed by ARM RVCT), the wrapper makefiles may fail.

    The wrapper makefiles created by qmake may cause conflicts with raptor’s make engine, the workaround is to run sbs directly or to use a GNU make with a different exe name (e.g. mingw32-make.exe) to run the wrapper makefiles.
    Symbian emulator
    Running multiple Qt applications in emulator is not possible. Starting second application will return KErrNotSupported(-5).

    The Emulator (32-bit Windows application) is limited to 2GB address space. Mwccsym2 links the debug symbols into the executable creating big chunks of memory, this causes a situation where even a small chunk of linear memory is too much to fit into the memory causing application/emulator just bails out without any error note. Error is easy to spot if the executable dies before reaching main() and you have just increased epocheapsize maximum in .pro file.

    Changing MegabytesofFreeMemory crashes S60 3rd edition FP 1 – emulator at start up.
    Installation on the phone
    Installing the qt.sis, that is shipped with the package, may fail due to stale state on the phone. Please uninstall any technology preview version from the phone, and repeat the installation once more.

    If Qt libraries are installed to memory card, startup of Qt applications is very slow due to Symbian doing additional checking of libraries found from removable media. Therefore, Qt libraries can only be installed to the phone memory (C.

    Distributed Qt .sis packages contain binaries built with armv6, making it impossible to run them on N96, which doesn’t support armv6.
    General issues (QtCore and QtGui)
    Sometimes widgets can grow out of the screen boundaries even with widget.showFullScreen()

    Apps that cause heavy CPU load for long periods can crash the launching process (e.g. application menu) with ViewSrv 11 panic.

    QLocale Symbian system locale support and QDesktopServices do not work properly in S60 3rd edition FP 1 builds/devices.

    QFileSystemModel sometimes creates duplicate nodes for files and directories if the file name and path case doesn’t match exactly the case of the file name in the file system.

    Font rendering: Vertical and very big fonts do not yet get rendered optimally.

    The “About Qt” dialog is too big and impossible to scroll, therefore not fitting properly fit properly on S60 device screen.

    IAP query dialog can be displayed each time socket tries to connect. For workaround please look at source code for FTP or Anomaly examples. There you can see how to set default IAP.

    Mouse events are not always sent to the correct receiver when pressing down and dragging.

    Using virtual keyboard to edit QLineEdit that has input mask only works properly if masked characters are filled in order starting from the beginning of the string.

    Using QWidget::lower() on a top level window will put the whole application to background. This will most likely be solved in the future by introducing separate window groups for each top level window. Note that this solution may impact the contents of the task switcher, making each top level window show up as a separate task.

    Switching orientation on a S60 3.x (like the N95) takes several seconds for some Qt demos. See bug report here
    QtNetwork specific issues
    Requires networkservices capability to connect to internet. Remember to add target.capability = networkservices in .pro file.

    Network using examples might crash (ViewSrv 11) when selecting IAP and while waiting for some longer time in “pre-shared key for WLAN” dialog.

    Network using examples will use first active IAP and that might cause connectivity issues in some cases (i.e. MMS access point in use at that time).
    QtWebkit specific issues
    Requires networkservices capability to connect to internet. Remember to add target.capability = networkservices in .pro file.

    Add target.epocheapsize 0x200000 0x2000000 in .pro files. This will set your minimum application heap size to 2MB and the maximum to 32MB.

    Running webkit examples will in most cases require you to increase memory usage of the emulator which can be done by editing MegabytesOfFreeMemory setting in %EPOCROOT%\epoc32\data\epoc.ini.

    Building webkit with -fpu vfpuv2 causes random crashes (kern-exec 3) when running javascript code.

    webcore.pro must be built from command line, building from Carbide runs out of memory.

    QtWebkit can only be build for release mode in armv5. Building debug will cause the RVCT linker to run out of memory.
    Bug Tracker
    A list of bugs reported on 4.6.x, which are fixed in 4.6.1 or later (or not fixed yet) can be seen at The Bug Tracker

    This is a public bug tracker, so you can report any newly discovered bugs using the “create new issue” link (after registering)
