Gui application failed to start

ferran.ripoll

I have compiled the qt 4.7.1 libaries for linux ARM, and all its dependencies (tslib, freetype, etc).

I have checked with qws/framebuffer application, the frambuffer is working properly.

I can calibrate the touch screen with the tslib tools.

Now I'm trying to execute a simple gui app, but I only can see an splash with the cursor, and the application finishes, without any error.

I have tried with different examples, getting the same result.

How can I see which is the problem?

Maybe you already tested it, but does this gui app work on emulator ?
Also can you post some code

seems like your gui applications are crashing on ARN device.

what is the configuration of your ARM board ? is simple "Hello World" label also fails to show up on that device ?

Have u checked if all dependent plugin component are already installed in that device ?

I didn't test the app on emulator.

But I'm testing the addressbook tutorial and the calculator example, and the result is the same.

Now I'm testing a simple application with an empty window, and the app crashes at window.show(), without any error.

ok what about console application ? does it work ?

could u please post environment detail on ARM board as well hardware detail of your board

ferran.ripoll

Yes, a console application works.

I'm using a development board from Hitegh with samsung s3c2440 processor, 7" tft screen (800x480 16bpp), and touch screen.

Linux kernel is 2.32.2, and gcc 4.4.3

Finally I have found the problem. The solution was:

I have compiled the Qt embedded without freetype2, and everything is working!!!
