Hello anandkushwaha,
welcome to LQ!
Please do not get into the habit of creating threads with uninformative titles such as "Help Me" -- many folks will either ignore your thread, or get bent out of shape over such titles
Please rename your thread (click EDIT + ADVANCED) to something that gives the reader some idea what the thread is about (maybe
"How to install GCC + deps on RedHat?"). Also, you may find the articles and information at the following link(s) to be helpful, as a new member of LQ:
http://www.linuxquestions.org/linux/...xQuestions_org
Kind regards,
Sasha
