Download the binaries from http://qt.nokia.com/. As of this writing, the latest version is 4.6 which comes with a lot of new features especially the multi-touch aware which is pretty much what is expected from latest generation of smartphone applications.
Change to the directory where the file was downloaded, like:
$: cd /home/username/$: chmod u+x qt-sdk-linux-x86-opensource-2009.05.bin
What we just did was to make the file executable. Finally, install the application by running the following command:
$: ./qt-sdk-linux-x86-opensource-2009.05.bin
See below for screen capture while installing Qt.
