install QT 4.6 on mini 2440

i've cross compiled the QT 4.6 for target Arm, on my friendly is istalled
the QT 2.2 have some one a tutorial, wich explain how to put the new QT on
the board?

Have a look at the tutorials from http://www.sereno-labs.com/

i've compiled yet the QT i've to put inside the friendlyarm to open at
startup the new graphic interface.

Hope I'm not telling stupidities, but I'm afraid you're confusing QTopia
with QT library. 

QT2.2 is QTopia (ie including a graphic desktop) and QT4.6 is QT library
only (without a desktop environment). QT lib will allow you to run normal
QT applications by starting them with the -qws option (embedded QT server)
or initializing QT with the embedded server option in your main(). But
there will be no desktop as QTopia's one.

So using QTopia or just QT lib depends on what you want to do.

Once again, I'm not a specialist in QT, and this is just my understanding
of the experiments I've done. So take this for just what it is :)

I the last few days just got my mini2440, so I was also little confused
about QT.
So from what you are saying QT 2.2 ( QTopia ) is the desktop GUI , whereas
QT 4.x are the libraries.
So if I`m making my own program without a GUI, I don`t need QTopia I just
need the libraries and my complied program ? , plus some form of Linux !!!.

hi peter

you can 
1.build your kernel,RFS,u-boot-bin using buildroot/OE(base-image or
Angstorm)
then 
2.x-compile tslib even before compiling QT4.x and install it in --prefix=u
set.
3.x-compile QT4.x with proper configuration switches. 
4. xcompile your application 
5.Copying tslib and QT-4.6 on target and setting the environment variable
which set your development system to work with Qt applications.

there r few blogs to do this ..for your help

Hi.
The board at the first time will have Qt2.2 (as Eric said, it's a graphic
desktop). And Qt4.6, it's just a library which you will cross-compile it
(i.e. compile it in other environments, like Ubuntu) and copy the library
into mini2440 board. Because Qt4.6 contains many advantages and funnies (i
guess ^^), you could upgrade Qt and enjoy the job :)
By the way, you can find the way installing Qt4.6.2 into mini2440 board,
