Qt for Symbian what now?:

It is now the 1st of December and we’ve just celebrated that we managed to deliver 4.6.0 on time. As much as I’d love to rest on my laurels for a little bit, you’re probably asking what is going to happen next now for 4.6.x and a coming 4.7. Here is a short brief of the things we’re looking at:

  • Fix deployment for Qt for Symbian (smart installer that downloads dependancies automatically)
    OpenGL ES
  • Heavy performance improvements
  • Drastically improve the install experience
  • Closer integration with Qt Creator
  • Fix bugs.
  • Proper Symbian Signed for Samsung and Sony Ericsson as well

If this happens for 4.6.1, 4.6.2 or later is not settled yet, but if you pay attention to this blog as well as our commits you will stay informed.

Thanks to:

  • My wonderfull co-workers, both in the porting team as well as the rest of Qt
  • Our partners: Digia, Tieto and Sosco (now Accenture) and the great developers they gave us (well, we ARE paying for them)
  • Other developers and managers in Nokia who has helped with autotests, signing Qt, tradeshows and more
  • The early adopters who have tried out Qt and given us feedback!

So, as of today Qt officialy has Symbian support. It took us roughly 20 months. We started with one person, and ended up with 15 fulltime developers. We’ll relax for half a day, then take a deep breath and continue on 4.6.1 and more long-term 4.7. But right now, we need another glass of champagne…


Espen is happy Qt 4.6.0 is out

Awesome work guys, just unbelievable. I have been playing around with Qt on Symbian and its just unbelievable how easy programming on symbian will now be.
πŸ™‚

serroba says:

if i want develop my own application in Linux, how i can???

serroba says:

and congratulations, this is a awesome work, like @Ahmad say. I love it.

espenr says:

@ahmad: thank you!

@serroba: you have to wait a bit longer, we’re working on it

Nils says:

Contratulations!

10 bottles of champagne for 15 developers. I don’t think you’ll do much work on Qt/Symbian tomorrow πŸ™‚

Raafat says:

Great Work!! Just like to point out that QT Phone Demos does not work on the Sony Ericsson Satio as during installation PIPS and open C claim that the device is unsupported and therefore do not install. One last thing, how can I develop on Mac OS X?

Congrats! says:

Hmm.. 10 bottles of champagne and one beer bottle opener? πŸ™‚ Cheers and congrats! don’t let them assimilate y

Dean says:

I really love the look feel of some of the demo applications. I can’t wait for some fully functioning ones – I may even have a look at making something myself.

ury says:

This is amazing! Only one question – is any chance to see qt-symbian SDK for linux ?

espenr says:

@Raafat: Open C is only signed for Samsung and Nokia, and Qt is only signed for Nokia. We’re working hard on getting Open C and Qt signed for all of them. I have a Satio myself here and want it to run Qt too πŸ™‚ And as for Mac OS X development – I’d develop my app using Qt for Mac, and then at the last steps move to a Windows machine with the Symbian SDKs installed – best advice I can give at the moment.

@ury: see above, already answered

Oscar B says:

Congratulations to all the team.
You are not just doing an amazing work, you are making history!

john says:

Thanks for the release. And keep in mind, many linux developers want to develop applications for symbian. I’m really looking forward to your symbian-qt release for linux.

Hi,

I tried to install demo from http://qt.nokia.com/phonedemos.

I could not install qt_demos.sis, After the dependencies are installed and Qt installation fails with error 10256.

Device: E51 , S60 3rd Edition Feature Pack 1.

Thanks,
Srini

espenr says:

@kksrini: See if you already had a previous version of Qt or fluidlauncher .sis installed, and uninstall these. Ideally reset the phone (*#7370# password 12345 – backup first!) if you can.

kksrini says:

@espenr: Thank you for the help. I have not installed previous version of Qt or fluidlauncher .sis. Let me try reset option after backup.

Thanks,
Srini
