#make install
On Simputer:
./app -qws

How many colours does your screen/frame buffer support?

The following is the configuration supported by my screen/frame buffer

240x320, 16bpp

I am not able to compile my qtopia app to this configuration.

I have also tested by using a short program that opens the frame buffer (/dev/fb0) and draws a gradient-filled red square.

It has executed successfully.

What may be the problem while using qtopia,Iam not able to understand.

please help me .
Thanks in advance.

I have the same problem.
I am sure that my fb is 16bpp and I have compiled qtopia core 4.3.3 choosing 16bpp.
Noone example works, it displays the same message above.

I'm using the same system with qt3.3.4 and it works with 16bpp without problems.

Any idea?

I sorted out the problem.
I configured qtopia by passing -depths 16 as argument as below

./configure -embedded arm -depths 16

Then downloaded libQtGui.so.4,libQtCore.so.4,libQtNetwork.so.4 to the arm.
Now Iam able to run applications but the display is not clear and the resolution is very bad.

Please try configuring as above.

Can any body send a sample code which works fine on arm for 16bpp screen depth and atleast specify url.

Thanks in advance.

take a look at ./configure --help
For example in my board i had to configure:
./configure ...... -qt-mouse-linuxtp
And export some vars like QWS_MOUSE_PROTO.

It works.

./configure -embedded arm -depths 16 -xplatform qws/linux-arm-g++ -qt-gfx-transformed -no-cups -qt-mouse-linuxtp

Now I have to make my ads7846 working.
What I'd like is to use good animations on my pxa255 400mhz.
For example something like animated gifs.
