Cross Compiling on BeagleBone Black

SPRB

The UI is being displayed as a output but none of the texts are shown.

SGaist

Are you running it directly on the target or using ssh/serial console ?

SPRB

I am deploying the application into target using Qtcreator itself. As Qtcreator provides that options.

SGaist

What language are you using for your application ?

SPRB

I am using "English" language itself.

Now I am trying to run my application which also includes images of type ".png", but now application is not at all running, now I am getting an error in console like :
"QFSFileEngine::open: No file name specified.
Bus errorixel: coordinate (-1,-1) out of range"

SGaist

Looking very strange, are you sure your target Qt is properly compiled/installed ?

SPRB

Ya I am sure, I dint get any errors I have installed many times without any error.

Can I know why that error "QFSFileEngine" error is there??
Though Images are there why it is unable to fetch it?

SPRB

Hi,
I resolved that "QFSFileEngine" error, it was searching for a file which I have specified in my application as I had not deployed that I was getting that error.

Now I am getting an error like:
"Cannot open input device '/dev/tty0':Permission denied
QImage::pixel: coordinate (-1,-1) out of range
Bus error".

Please help me why this Bus error is coming?

SGaist

It seems you do not have the rights to access the console, what are the rights of /dev/tty0 ?

SPRB

Rights for /dev/tty0 is "root tty"

SGaist

Are you running your application as root ?

SPRB

No I am not running as a root.
If I run as a root I am getting the following error:
"Qt for Embedded Linux data diirectory is not owned by user 0: /tmp/qtembedded-0"

SGaist

Either:

Add you user to the tty group
Delete /tmp/qtembedded-0 and restart your application
