Get Qt example running on SAM9N12

[SGaist]

What exact error are you getting ?

Unless you plan to run Qt Creator on your board, no

[Bizer]

On board the board: -sh: ./example: not found

[SGaist]

What does file example return ?

[Bizer]

On the SAM9N12-Linux "file" is not installed but on ubuntu(compiling PC) it says:
benephil: ELF 32-bit LSB executable, ARM, EABI5 version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 3.1.1, BuildID[sha1]=00493b39dc19cde81d1b1ac906499c24698e97f4, not stripped

[SGaist]

Good, but the thing is, it doesn't seems that the file is copied over to the target

[Bizer]

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.

[SGaist]

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

[Bizer]

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?:

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.

[SGaist]

What distribution is running on your board ?

[Bizer]

At91linux with buildroot-rfs

[SGaist]

Did you install Qt 4 directly through Buildroot ?

[Bizer]

Yes, i did

[Bizer]

no further ideas?

[SGaist]

Did you also cross-compile Qt using the libraries from Buildroot ?

[Bizer]

On the dev machine no, on the evaluationboard yes

[SGaist]

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 ?

[Bizer]

Yes, but it should be the same version. Buildroot uses 4.8.6 and on the dev machine i also had 4.8.6

[SGaist]

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

[Bizer]

Ok thanks, do you have any hints what i have to look for, to get the same dependencies?
