Nokia has recently announced Nokia N9 with MeeGo 1.2 "Harmattan. Some forums are saying
that it is differed from intel MeeGo. Is it true? What is Maemo?
Is Maemo same as MeeGo Harmattan? Where can we download SDK to develop applications for it with simulator? Is Intel meego sdk (Intel note book, tablets) enough? Any guide please?
Nokia has recently announced Nokia N9 with MeeGo 1.2 "Harmattan. Some forums are saying that it is differed from intel MeeGo. Is it true?
They have different package managers. Nokia's MeeGo is DEB-based, Intel's MeeGo is RPM-based.
Nokia's MeeGo 1.2 Harmattan API = Intel's MeeGo 1.2 Core API + Nokia Specific APIs
So, the main part of the API including Qt 4.7.2 and Qt Mobility 1.2 is well compatible.
See also binary compatibility report between MeeGo 1.2 Core and MeeGo 1.2 Harmattan on x86 generated by the abi-compliance-checker tool.
From the Nokia Glossary:
MeeGo 1.2 Harmattan API
The official name for Harmattan API. A recommended set of APIs in the Harmattan platform to be used for
application development. MeeGo 1.2 Harmattan API consists of MeeGo API and Nokia Specific APIs, and it is a subset of Platform API.
MeeGo API
The set of APIs that are supported by all MeeGo-compliant devices and available for MeeGo application
development. MeeGo API is a future-proof set of APIs that is forward-compatible within a major MeeGo
release. MeeGo API is a part of MeeGo 1.2 Harmattan API.
Nokia Specific APIs
Nokia Specific APIs contain additional libraries that can be used when creating applications for Nokia
devices. Nokia provides compatibility to this API set for the next two major Nokia releases. Nokia Specific
APIs are a part of MeeGo 1.2 Harmattan API.
Other questions:
What is maemo?
Maemo is the Linux-based innovative platform from Nokia started in 2005. It's installed on N900 (Maemo 5), N800 (Maemo 4) and other experimental devices.
Is maemo same as MeeGo Harmattan?
Yes, Maemo 6 and MeeGo 1.2 Harmattan are two names of the same platform.
Where can we download SDK to develop applications for it with simulator?
The Harmattan Platform SDK including the emulator is here.
Any guide please?

I am curious about the qt version used on Blackberry 10 momemtics IDE. Can I use QT5 for blackberry 10 development ?
Directly from the documentation you can find here.
The current release of the BlackBerry 10 Gold NDK
[developer.blackberry.com] includes Qt 4.8 for both the simulator
target (x86) and device targets (arm) available for development.
Compared to the development for the PlayBook, Qt is integrated in the
BlackBerry 10 device firmware and so can be used by Qt applications as
shared libraries.
The page is quite detailed. Have a look at it.
However, Qt5 can still be considered. You can find more information on how to use this Qt version in this other page, which states:
Currently, Qt5 is neither included in the BlackBerry 10 device
software nor in the BlackBerry 10 SDK. However, Qt5 on BlackBerry 10
has reached a excellent level of quality and can be used for
developing and publishing applications to BlackBerry World.
BlackBerry 10 supplies only Qt 4 libraries.
You can use Qt 5 as long as you bundle your application with self-built Qt libraries.
Here you can find detailed information.
The number of mobile operating systems or platforms supporting QT based app development keeps growing. Not for all of them QT is the standard framework for building apps, therefore it seems the Qt support can be categorized as follows:
Qt and Qt based technologies (QML, QtQuick, QtMobility) are the recommended way for building mobile apps and part of the SDK.
Qt or a subset of Qt is supported as a secondary way of developing or porting apps, and there is support for a subset of QT APIs within the SDK.
Unofficial 3rd party or open source extensions enable development of Qt based apps for a platform.
Which mobile operating systems or SDKs do support development of apps using Qt in either of the above listed ways?
Mobile operating systems with full Qt support in the SDK:
Nokia Symbian OS: http://www.developer.nokia.com/Develop/Qt/. Since Nokia discontinued Symbian, Qt for Symbian is a community effort now.
Nokia N9 / MeeGo 1.2 Harmattan: Full Qt support.
Mer (community Meego fork) and Sailfish OS: Qt/QML are both supported.
Canonical's Ubuntu Phone uses the Ubuntu QML toolkit and Qt Creator for native application development.
Mobile operating systems supporting a subset of the QT APIs:
Blackberry 10 OS and SDK: The Blackberry 10 SDK contains the Cascades UI framework, which is built on top of a subset of Qt 4.8 and QtMobility modules. Apps can be created using Qt, QtMobility and QML/QtQuick. Another approach is porting an existing Qt application that uses QtGui.
Digia, community driven (open source) and 3rd party extensions targeting mobile operating systems:
Android: QT 5 port by Digia (demoed at Qt Developer Days Berlin in Nov 2012), expected to be released by the end of 2013.
iOS: QtQuick 1.0 port by Digia (demoed by Qt Developer Days Berlin in Nov 2012), expected to be released by the end of 2013.
WinRT / Windows 8: (demoed by Qt Developer Days Berlin in Nov 2012) demo.
Qt for Android port Necessitas: Has been donated to the Qt project in Nov 2012.
Qt SDK for iOS devices by Mediator Software: The product website does not contain much information, but there are regular updates on Twitter Qt4iOS (links to apps in Appstore built using QT SDK for iOS are posted on Twitter).
I need to develop applications for nokia devices running S60 3rd Edition, Feature Pack 1, S60 3rd Edition, Feature Pack 2 S60 5th Edition, Symbian^3 the documentations in nokia forums is not quite understandable. I understand that at present to develop applications for nokia device qt to be used. Now there are two versions of qt SDK 1.1.4 and qt SDK 1.1.2
Which should i download to develop applications for the all the three symbian platforms..?
I think you should stick to 1.1.2.
Qt SDK 1.1.4 contains only the latest targets for developing applications for a particular Symbian platform. The targets for Qt 4.6.3 for Symbian and Qt 4.7.3 for Symbian^3 and Symbian Anna have been removed from Qt SDK 1.1.4. To develop for these targets, use Qt SDK 1.1.2. Once you have installed Qt SDK 1.1.2, to enable use of the earlier targets and App TRK, don’t run the SDK update as this will remove the features you need.
I am developing an application for Nokia Symbian since last two months, Nokia is a new platform for me I have good experience in iPhone development, I started Qt SDK 1.0 what I found 1.0 was not really good for some mobile device specially in UI, I just moved out to Qt SDK 1.1 released on 1st March 2011 I went through QML (Qt Quick) I found it really good in UI experience, finally when I reach to OVi for publishing my application OVi just refused my application due to Qt SDK 1.1 which is not supported on Nokia Symbian devices yet.
Again I cam back to Qt SDK 1.0 I used QDelearativeView and used same QML structure its working fine on simulator but when I am trying to build it for Symbian device I am getting error "no such file or directory".
Now I have number of questions listed below
1 - How can I fix this error and publish it to OVi
2 - Any good resource for publishing & signed process for Symbian devices
3 - Any expectation how much long Ovi would take to support Qt SDK 1.1
Thanks in advance,
Mohammad Asif
Qt SDK 1.0 contains Qt 4.6.3 which doesn't support QtDeclarative. SDK 1.1 Beta contains Qt 4.7.2. That's the reason for compilation error.
According to this, you could build your app on SDK 1.1 Beta, package it with the currently available Qt Smart Installer and submit it. Though it will only be deployed to store once Qt 4.7 based Smart Installer is available.
For Ovi Store related questions I suggest you consult Forum Nokia's Publishing to Ovi Store forum.
i'm a little bit confused about all the different nokia SDK, what do i need to develop apps with c++?
the nokia QT sdk oder the nokia symbian^3 SDK
You can use either one. Obviously, if you want to develop Qt-based Symbian apps you will need the Nokia Qt SDK. However, Nokia has clearly and repeatedly stated that Qt is the future of Symbian development going forward, so for all new code, use the Nokia Qt SDK.
