Create Apps for mini2440?

Hi,

I have been looking all over these forums to see what is the best way to
create personalized applications for the mini2440 and no one has specified
a clear way. I am using Qt4 (I have Qt Designer and QT Creator), but when I
make applications and transfer them to the device, the app will not open
when I click on the icon. 

Do I need to add something to the code that QT Creator develops or do I
need something else that will make my applications useable on the mini2440?

Thanks,
Nick

Have you still got Qt2.2.0 on the machine?  If so, there have been a number
of posts of how to run Qt4 apps on a machine that still has Qt2.2.0. on it.

I don't have Qt2.2.0. on the machine. Basically, I recently purchased the
mini2440 and downloaded and ran Qt4 thinking that it was the best way to
create the apps. 

If I am going in the wrong direction with this please let me know. I was
able to successfully run the example hello program that came with
arm-qtopia, and now I want create a similar program (using Qt4 or whatever
is best), but don't know where to start.

If you could lead me in the right direction I'd appreciate it.

What OS do u use?

You have successfully cross-compiled the Qt and placed the Qt/libs on the
target?  Which tutorial do you follow?

@ Ann R.--I am using Linux

@ davef--I am guessing that is my next step. Could you send me a link to
what you think is the best tutorial to do so? Sorry, I am a newbie intern
trying to learn my way around this stuff.

Thanks!
Nick

Nick,

Sorry, I didn't pick up that you are already running Qt4 on the mini2440. 
I should try that image on the downloads page!

As for developing programs in Qt have you done the tutorials on the Nokia
site to get a basic understanding of the process.

1. Develop application for the desktop
2. Try to run using the framebuffer
3. Then cross-compile and run on the mini2440

I haven't been through this myself.  I have spent hours and hours trying to
cross-compile Qt4 from source, instead of actually writing applications :(
