where the programs i installed

to install support for restricted formats like mp3 you can follow this guide: https://help.ubuntu.com/community/RestrictedFormats

when you 'install' a program via compiling it (the way you did) you are expected to make the shortcuts yourself, you have to type the name of the program executionable in a terminal to launch it

thanx for your fast replay

but is there is any other method of installing programs rather than compiling ???

it take long time

Many programs are already compiled for you in the Ubuntu repositories. These programs, by and large, will create shortcuts and load dependencies, so it is a good way to install software.

To do it in a graphical environment, go to System->Administration->Synaptic Package Manager. Then you can search for various software packages.

Depending on what you are looking for and how your system is set up, you may want to enable a few extra repositories. One way to do this is in Synaptic is to go to Settings->Repositories, and make sure that everything on the first tab is checked, then click close. You then need to refresh the package list, click the reload button.

Good luck.

Ubuntu does not recommend compiling application from source but hunting for the .deb package of the application.

thanx all for ur replay i will try it and back with the results
