I picked a Lumia 530 for Christmas to see how does Qt perform on Windows
I have not used a Windows Phone before, so some of my struggles can be
attributed to that.
I'm somewhat newbie with Windows 8.1 as well, more used to Windows 7 or
I installed Windows 8.1 Pro 64 bit to VirtualBox virtual machine,
installed Visual Studio 2013 pro.
There already was Visual Studio 2012 in the virtual machine, and Windows
Phone 8.0 SDK seemed to bring in some express version as well.
Host in this case is Kubuntu 14.04 amd64 running on older Dell studio 17
with core i5, 6 Gb of ram and 250 Gb SSD. I let the VM have about 3 gb
Connected the phone with usb, ticked devices/usb devices/Microsoft Lumia
530 in the VirtualBox so that the phone was visible to the virtual machine.
I started Visual Studio 2013 and registered the device for development
there, I'm not sure if this a required step but would expect so.
Downloaded Qt online installer, which spent a long time setting
I tried to tick pretty much everything required for Windows Phone
development, but in the end I did not see Windows Phone arm kit
anywhere when Qt creator started. Perhaps I made some mistake.
Went to control panel and uninstalled Qt to start again.
I downloaded Qt 5.4.0 for Windows RT 32 bit offline installer and
Now success, I got three kits: Windows Phone arm MSVC2013, Windows Phone
x86 MSVC2013 (emulator) and Windows Runtime 64 bit. Note that I cannot
run the emulator, VirtualBox does not expose the hardware virtualisation
support to guests and the emulator requires it.
I tried building the default qtquick app wizard generated app with
everything as default, Qt Quick Controls 1.3. It built and installed,
showed the Qt logo full screen on the phone for a couple of seconds, and
then closed. On Windows Runtime it worked ok, showing the 3 buttons.
I tried another app, now picking Qt Quick 2.4. This time it ran on the
phone, but the MouseArea did not respond to any touches. So it
displayed "Hello World", but did not exit when tapping it, only exited
with phone UI back button.
I tried a third variation, but that resulted in this message: Failed to
install the package: 0x81030119 "Unable to install application. The
maximum number of developer applications on this phone has been reached.
Please uninstall a developer application and try again."
So the maximum number of developer apps by default is 2 for windows
phone, wtf!? I guess google time to find out if this limit can be
Another note, for some reason Qt Linguist, Designer and qt3dservice
each now appear 3 times on Windows 8.1 Apps by Name list (metro desktop?)
Right now I'm only impressed by Lumia 530 itself, which seems to be
solid and responsive phone for under 70 euros, but I'll continue testing
