You don't. Different systems (and languages) have different conventions, but nowadays they're mostly all relative. It's part of the job of what you're writing to conform to any external requirements and make your own determinations where there aren't any to conform to. You have a fair bit of reading ahead of you. Mere compilation is only a part of the job, albeit not a trivial part.
