I have compiler options to check the folder "SDL/include" for the include files and "SDL/lib" for the lib files. then i explicitly include the library in the code by doing #pragma comment(lib, "sdl.lib"), but when i run the program it's saying that it's missing "sdl.dll", how do i link that or however i need to add that?

sdl.dll needs to be in same place as your .exe or in windows\system32.

The lib files only exists to tell the app how should it use the DLL files.

The license won't let you have the complete SDL embedded in your app.

ah.. ok, i had to put it in the same folder. thanks, but now i'm getting an error with the Uint8 type... i guess it's not seeing it or something. is ther something wrong with it? ic an't just declare a variable with type "Uint8"?

I'd check all the spelling/caps on "Uint8", since it sucks to miss really stupid errors - but I never had a problem with that when I set up. Maybe it's a linker thing?

You will need to include "SDL.h" in that file that it's not found in. As the other AP above posted, Uint8's are just typedefs and right now, that definition is missing.

Although, if he was missing that wouldn't he get undefined's for everything with 'SDL_'?

He would, except in the most common case that this is happening in another file, perhaps a header file, that does not yet use any SDL code. For example:

KeyBoardInput.h

#ifndef KB_H_#define KB_H_class KB_Input{   private:      vector <Uint8*> bufferedKeyArray;   public:      KB_Input();      ... member functions ...}#endif

KeyBoardInput.cpp

#include "KeyBoardInput.h"#include "SDL.h"KB_Input::KB_Input(){}... rest of member implementations ...

Off topic, but why did you use a vector, if SDL_GetKeyState(...) returns a snapshot of the program?

I'm assuming he'd be using a polling system for the input so that he can buffer the input in order to be able to get more then just three key presses at a time.
