help me out in QT
 

what do i need to build applications on mobile platform Qt Embedded or Qtopia, i m having Qt designer with Fedora 9, is it sufficient to build gui apps to the mobile platform ,m using intel PXA255 Board(ARM core 10 processor), and how can i cross compile .ui fles to execute them into my board?

Your embedded QT toolkit must have surely provided the needed info and tools. The .ui file is just a config file, so it will be portable, but your request for cross-compilation infos indicates that you want it build it on your Fedora box anyway. I'm pretty sure that you will need some commercial tool from QT for this purpose.

i got the toolchain now , but i dont know how to compile a .pro project file for my arm board, m able to compile for x86 system

Usually you need to:

1. run qmake if you have no Makefile or the default Makefile fails to build.
2. run make.
3. launch ./your-application-name-here

When recreating the Makefile, make sure to have the needed headers and library files added.

I have read that cross-compiling Qt/X11 is not supported, but I can neither confirm nor deny that statement. You must also make sure to setup the cross-compile environment correctly. An error like
"include/qglobal.h:156:4: #error "Qt has not been ported to this OS ..."
actually means that none of the expected macros that describe the OS are defined.

Actually while installing Qt-embedded we have to give the path of the cross compiler so that it will take the gcc, in my case arm-linux-g++ is placed in the bin, so i have given the path and it successfully built for arm architecture it doesn't run in X86 system i checked using the command file binary-name, it gives the out put like the ELf is run on ARm ver 1 ...(etc)(i dont remember it), the thing is i have to place the executable in the target board , but it shows the error whn i tried to execute it , that it requires the dynamic libraries, so i need to install gcc 3.4 which supports Qt-embedded 4 , i will it if i wont get pls help me out
