Get Qt example running on SAM9N12
Good, but the thing is, it doesn't seems that the file is copied over to the target
Sorry, I don't get it. What do you meen?
I copied the folder with the crosscompiled files from my PC to a usb-stick, mounted the usb-stick on the Evaluationboard and tried to run the example.
Then that's normal, the libraries can't be found, you should write a little bash script that setups the environment for your application to run. Have a look at the Linux Deployment Guide for more details about this

Ok so i probably have some libary issues... With crosscompilation everything should be fine? Do i have to write a bash script for those libaries?:

not a dynamic executable
Hey, i observed one thing: If i run the project in qtcreator and check the "run in terminal" i get a: "Syntax error: word unexpected (expecting ")") "
Is there something i can/should do about this issue? Because if i run "sh example" i get the same error.
What distribution is running on your board ?
At91linux with buildroot-rfs
Did you install Qt 4 directly through Buildroot ?
Yes, i did
no further ideas?
Did you also cross-compile Qt using the libraries from Buildroot ?
On the dev machine no, on the evaluationboard yes
Just to be sure I understand you correctly: you cross-compiled Qt on your desktop using a different set of libraries rather that than the one from your evaluation board and you compiled natively on your device ?
Yes, but it should be the same version. Buildroot uses 4.8.6 and on the dev machine i also had 4.8.6
Same Qt version is one thing, but it looks like you don't have the same set of dependencies between both versions and maybe not the same set of options given to configure
Ok thanks, do you have any hints what i have to look for, to get the same dependencies?
Use your device root filesystem as sysroot to cross-compile Qt
Ok i added the compiled sysroot that i compiled with buildroot. I got the same error:
Here is a screenshot incl. the syntac error when I'm building the project:
Hi, sorry but doesn't any one have an idea?
What do you have where the syntax error occurs ?
