when i go to build hello world in sega genesis compiler in code blocks it exit that error in this picture:

I don't believe the genesis SDK was ever publicly released.

Assuming you are using a homebrew library you're going to need to ask the source you got it from.

I Don't Won't Your Idea's I Want A Help.

This is a volunteer forum, demanding we help you is inappropriate and rude.

For help, I strongly suggest you begin by learning how to program on a current system as they are easier to deal with. Once you learn what you are doing the error message you showed in the first screen will become painfully obvious.
