Get Qt example running on SAM9N12

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?

SGaist

Use your device root filesystem as sysroot to cross-compile Qt

Bizer

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:

Bizer

Hi, sorry but doesn't any one have an idea?

SGaist

What do you have where the syntax error occurs ?
