i'm so sorry. but i don't come here always. so it's confused to me.
but now i have the answer that i didn't knew.
by default, the mingw have the directx headers files for i use. so i don't need do anything, just learn and use them.
i'm sorry, again, i, more or less, understand what you said(i'm Portuguese). my question was on sub-forum wrong or you only work with IDE options and configurations and nothing more.
i'm sorry and thanks for all. thank you
