I'm not sure whether it's stupid to ask this question here. Maybe it's too easy a question to answer, maybe you think that I am too lazy to post a question before do a good search on google, or read the document offered.
But English is not my first language, and it is a ton of words to read in order to just compile some pieces of code. And I got no one to ask, and there are no place where I can ask for help except here. If it's too much to type, just give me some hints to google. Help me, please.
