Dear all,

I'm trying to write a GUI program for Power PC with 300e CPU and PCI graphic card on it.
I wrote it on x86 Linux system and cross-compiled it.
When it running in Linux on Power PC, everything is fine except the colors.
It seems the endian problems because I have done some tests for the framebuffer with different endian.
The x86 system is little-endian and Power PC is just the opposite,
so there might be something wrong when processing the RGB values.

I tried to re-configure the Qtopia with "-big-endian" when cross-compile, but it didn't work.

I wonder if it works or not by modifying "qscreen_qws.h".

Please give me some suggestion to solve this problem, thanks.

Is there anybody tried running Qtopia progams on PPC?
Is there anyway to change the color byte order from argb to gbra for Qtopia GUI programs?
The endian settings for Qtopia seems affecting only data except the GUI image colors.

I use the style sheet to design the looking for the GUI, and it seems useless to change the QRgb definition.
What function will the style sheet call to implement the style sheet syntax?

I wonder that my questions are too easy, and no one would answer, hehe...
Actually I'm newbie for Qt and embedded programming.
Thanks for your help anyway.

Thanks for your reply.

I've tried the ENDIAN flag while configuring, but it seems useless.

I'm contacting the video card menufacturer to discuss about the offset problem.

My Screen is Samsung SyncMaster 750s, CRT.

Is there anything I should pay attention about screen?
