Sorry about the stupid questions.
But I've tried so many times to get one example on my N900 but failed.
(It has firmware PR1.1.1 now)

I tried camera example, toolbar examples in maemo examples.
They works fine in scratchbox.
But when I compile/make them under sbox-FREMANTLE_ARMEL and put them on N900, I failed to execute them.

On N900, the programs can't be executed by just double click.
So I open a xterm window do the following statement.

'sudo gainroot'
#sudo ./example_file_chooser

But there is nothing happened. No application launched and no error message shows.

I don't know if I missed something needed on N900. Do I need to install anything on N900?
Basically, I following this post to compile my application.

Thanks for any advise.
