Cross Compiling on BeagleBone Black

SPRB

No I am not getting any error on the console. Everything seems to be fine.
I even tried by generating the fontdir file for the fonts, thinking it might be searching for that fontdir file. But I could not achieve success out of this.

SPRB

I also tried several ways for getting the text displayed. Like setting the QT_QWS_FONTDIR to my font dir, By setting the QWS_DISPLAY, also I tried to run the application by giving the following command: "./Test -qws -font unicode" but couldn't achieve any success.

Please direct me where I am going wrong.
Waiting for an helpful suggestion.

What output do you get on your console when running your application ?

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
