Install Smile on Ubuntu 9.04

Smile is a Slideshow creator for Linux. Previously I used Manslide and made some very nice slideshows with it, like these:

Manslide was a great program, first was hard to use, but gradually improved in stability and effects.
After a time the author decided to drop it and recreated a better program, called SMILE - Slideshow Maker In Linux Environment. Can be downloaded at the kde-apps.org, or at the author's website at http://smile.tuxfamily.org/

I had no chance yet to use it, but here is how to install it under Ubuntu:
1, Download, extract to a directory
2, sudo apt-get install qt4-dev-tools build-essential sox libsox-fmt-all libqt4-dev
3, go to the directory and type: qmake-qt4 && make
4, now create menu links to the smile named executable


If you find it usable, you could support the author, his message is here:
