actually it is available on ubuntu's live cd too
sudo apt-cdrom add
(now insert cd in cd rom and fireup command given below)
sudo apt-get install build-essential
(after downloading all the essential package test whether gcc is working properly or not by creating simple "Hello world" program u can compile any c program using this command "gcc -o fileName filename.c" without "" or by using make)
