[Solved] how can i install Qt-mobility on meego n950.

FYI: Leon has gently updated the wiki page with the following note:

Qt Mobility is compatible with MeeGo OS. Please note that this tutorial affects devices (netbooks and tablets) with MeeGo and it is not appropriate for MeeGo Harmattan devices (Nokia N9 and Nokia N950).

Hope this will clear your question. If any don't esistate to ask.

@Alicemirror it is not appropriate for MeeGo Harmattan devices (Nokia N9 and Nokia N950)
What does it means? Is QtMobility already installed on N950? or will it install through other way?
Becuase I am developing project for Nokia N950.

The libraries that you install are on your development device i.e. windows or linux or Mac machine. Then the compilation creates a package including all the components needed to your application.

it seemed very strange to me the need to install something on the N950 enabling the application to run :)

There is only a slight difference on symbian devices where you can decide to install the package only and the libraries and components as a separate package or all together controlled by the smartinstaller package.

I think that to use Qt Mobility on N950 you should update your Qt SDK with the Mobility components and compile + package + deploy your application on the device.

[quote author="DanSiddiqui" date="1315980225"]@leon.anavi thanks bro, but i don't think QtMobility installed on N950.[/quote]

Qt Mobility is installed on N9 and N950 you can check the "official information about Nokia N9":http://www.developer.nokia.com/Devices/MeeGo/:

bq. Qt Mobility 1.2.0 — adding support for Bluetooth and NFC technology.

Btw as a proof that Qt Mobility is present on N950/N9 - I have already developed and published at Ovi location2sms an app using Qt Mobility that is running on MeeGo Harmattan devices and I did not have to install anything additionally.

@leon: I thought this but I was unsure. I have not found the link. BTW for him I think that nothing changes. He should install all the components on his development environment for compilation and linking then all goes right. Is it true ?

Ok its great if Qt will installed automatically Qt libararies or API.but i am sure about it.
One more Question I have lots of project which i developed for Symbian^3 devices, when i opened it for Harmattan device it is not getting the includes files.
with error message= No such File or Directory
#include <QMessageBox> //No such File or Directory
#include <QSqlDatabase>//No such File or Directory

Yes, absolutely.

@DanSiddiqui please follow Alicemirror's advice about the development environment. If you do everything fine you should be able to port your pure Qt applications for Symbian^3 to MeeGo Harmattan easily.

Thanks leon.anavi , Plz tell me the source code project or any example project
for harmattan device(N950).so i will check it on my N950 device which includes mobility API.
if you url plz tell me i will download it on my PC.

so why error displaying on my .cpp files:
error message= No such File or Directory
#include <QMessageBox> //No such File or Directory
#include <QSqlDatabase>//No such File or Directory

@DanSiddiqui: please tell us what development platform you are using.

From Windows you should go in the program manager / Qt sdk / and launch the Qt mainteiner or updater. See if you have installed the Qt Mobility library or if your library should be updated. Please note that it is possible that some components (following the indications in the labs blog about releases) with Qt 4.7.4 part of the development environment will be found in the experimental section. Then see what is your actual development environment configuration, what components you have installed. It is possible that something goes wrong just because you have not all what you need.

You see this error just because the related libraries and components your need in your SDK are not installed. This is NOT a problem on your device, it is a problem of your development environment on your PC.

Please check "this tutorial about porting applications to Harmattan":http://harmattan-dev.nokia.com/docs/library/html/guide/html/Developer_Library_Reference_documentation_Porting_applications_to_Harmattan.html I strongly recommend also reading the rest of the "MeeGo 1.2 Harmattan Developer Library":http://harmattan-dev.nokia.com/docs/library/html/guide/html/Developer_Library_MeeGo_1.2_Harmattan_Developer_Library.html

Yep, I think that you should have your ideas a bit more clear on how the entire system architecture for development works.

DanSiddiqui · wrote on 14 Sept 2011, 07:15

I have the lastes Qt sdk when i run updater it shows me "no update availabel". I have Qt 4.7.4
having mobility 1.1.3.

it work fine when i select simualtor on left panel project tab all
#include find on QTcreatorbut i select Harmattan to build it shows me underline having message
No such File or Directory

Alicemirror · wrote on 14 Sept 2011, 07:34

You should not check for update (4.7.4 for now is the last) but for maintain and see if all your components are installed, including Mobility - I think - you find in the experimental section. This section will be installed only if you select a custom installation so it is possible that you have not done it when installed your first version of Qt 4.7.4

Then, you mention the simulator. Simulator is for symbian devices, and QEMU (formerly emulator) if for Harmattan and Meego (linux) devices.

Then please read the previous posts, we asked you what platform are you using etc. This questions are useful to understand what can be wrong in your configuration, if any.

i am using Window 7 on my PC, Qt creator 4.7.4 as Development and Nokia N950 for deployment, so i select Qt mobile application and target as Harmattan(MeeGo) for N950.

Alicemirror · wrote on 14 Sept 2011, 07:47

It seems all correct. Please check what are all the components that you have installed in your Pc. You can see the list with the package manager expanding all the listboxes to see components and subcomponents.

Alicemirror · wrote on 14 Sept 2011, 14:45

Is this problem solved ? If so please set the first post to solved. Thank you.

DanSiddiqui · wrote on 15 Sept 2011, 18:26

yes if Qt mobility already installed on N950 as said by leon.anavi.
Thanks leon.anavi and Alicemirror for quick response.
