Hi,

Are you testing app on emulator or phone?

If you are testing app on emulator..than debug code line by line and check which line it's crash.........Generally this error comes Resource missing.....

[mahbub_s60]

This code looks fine. In Symbian -1 means not found, have you commented or removed some code from your project so the initialization is not happening properly?

i have recently found that its not because of code! its something else!! i have tried to install the QT built in examples too ! they also give the same error.Don't know why??

[samurai307]

my emulator doesn't work.So m trying my first app on my cell!! Moreover ,when i build the files for my device,the software gives me the
error
plz tell me
Launching: calculator.exe
Launch failed: Command answer [command error], 1 values(s) to request: 'C|8|Processes|start|""|"calculator.exe"|[""]|[]|true'
#0 {"Code":-1,Format="Failed to create the process (verify that the executable and all required DLLs have been transferred) (item not found)"}

Finished.

Was your coda sw in the phone was running and was connected to your PC?
Could you check that and also create the wizards to create a simple hello word type application and try to install and run it.
Please repost your findings here.

@mahbub_s60 !!! i have also tried to install the built in QT examples!! but when installed!! they don't run!!

[mahbub_s60]

I guess it is better to try first with simple helloworld app generated by wizards. Some examples application might need to have certificate to install. So that may not work.
Best way would be follwo the wizards and create a simple helloworld (make sure your CODA sw in the Phone side is working and connected with PC).

Once we are able to run this simple app then we can try to run other example. Could you try and post the result here. Or you can check the step by step guide that is available in QtSDK (in the welcome page)

[mahbub_s60]

You need to install Qt in the phone? Do you have it?

[samurai307]

yes i have installed QT 4.7.4,Qt Mobility,QT quick components provided with latest QT !! but still the apps don't run!!

[mahbub_s60]

Hi,
Have you seen this doc? It says
The Qt 4.7.4-based bundle is not supported in S60 5th Edition devices where the last supported Qt version is Qt 4.7.3. To support this Qt SDK 1.1.4 has the Qt 4.7.3 for S60 5th Edition build target (this was earlier named as Symbian^1).

[samurai307]

@mahbub_S60! So,what should i do then??? reply me plz!!

[symbianyucca]

I suppose Mahbub is telling You that you should build for supported target, i.e. as your device is 5th ed devicem you should use the target that is supported by it.

[samurai307]

@symbian!! What do u mean by "You should use the target that is supported by it" ?
