I've built a game for linux, and now I want to build a RPM package. I've read the HOW-TOs and my rpm works.
Now, I just have a question about 'Requires' in spec file:

How do I know what do I need for this project?
I mean, I know that I use SDL and SDL_ttf, but how do I know which version of these packages do I need? (You know, so I can write i.e. SDL>=1.2.3)

+
I wrote this in C++, and using SDL and SDL_ttf.
Do I need any C++ stuff? Probably not for the normal 'Requires' section, but for 'BuildRequires'?
Do I need a library for <iostream.h>, <stdio.h>, <stdlib.h> ? Which library is it?

Thanks
