1. Install OVI Suite on your PC
2. Connect and setup your 5800 to work with it
3. Go to Start -> All Programs -> Nokia Qt SDK -> Symbian
4. Click “Install Qt to Symbian device”

Next time, read this page: http://doc.qt.nokia.com/nokia-qtsdk-1.0/creator-developing-symbian.html [doc.qt.nokia.com] :)

but this not good, when for work application size 100kb must install QT pack 10mb,

The N8 comes with Qt already installed, but other existing phones needs to get Qt installed somehow.

More info here [wiki.forum.nokia.com].

This 10MB pack needs to be installed only once. New Qt applications won’t install it again.

but when we load another applications, they not want another pack, or not?

i think need compile application with library, and program will have needed libs =)

Mimik: New devices will at some point come with Qt pre-installed.

Up till then (or when targetting older devices) you need to make sure the libraries are available on the device. Using the smart installer is the best way to do that: At least the user will not end up having to download the libraries over and over again and it will further detect pre-installed Qt versions on new devices.

Statically linked Qt for Symbian is really not supported. Try the Smart Installer before you go there :)
