How to install Qt4 in Ubuntu 12.10

I tried to use Qt5 but I have some problems while making Debian packaging process with Qt5 so I would like to have Qt4 on Ubuntu 12.10. How can I install Qt4.


Just download Qt-4.8 from here and run the self-installer

http://qt-project.org/downloads

or install it from ubuntu software center (two package)

qt-sdk

qt creator
