Did you add SDL's headers to your compiler's include path?

 

When you do #include "another file", your compiler looks for 'another file' in a series of locations, and if it can't find the file in any of those locations, it gives an error.

The locations depend on what compiler you are using, but mine goes something like this:

  1. Checks in the same directory as the file doing the include
  2. Checks in the root of the project being compiled
  3. Checks any other user-defined include directories that the compiler was told to search
  4. Checks the compiler's include directory (actually, there are several include directories the compiler has built-in, and it searches them in order)

I might have the order wrong, but it checks all those locations in some order or another, until it finds the file it is looking for.

 

If using '<' and '>' brackets, like #include <file>, the compiler I use checks the compiler's include directory first (usually the standard library headers).

 

So, if you are wanting to use SDL, you'll need to:

A) Link to SDL, using the linker file (the exact details depend on your IDE)

B) Make sure the DLL files are either in your operating system's %PATH% environmental variable, or else alongside your executable.

C) Add SDL's include files either in the compiler's include directory, or else add a user-defined include directory.

 

I suggest starting with Lazy Foo's SDL tutorials - they'll walk you through how to get SDL up and running with a custom tutorial for whatever IDE you use. The entire tutorial is an excellent introduction to SDL, in my opinion.

In addition to all of the above points, the standard and most "cross-platform" way to include SDL is:

 

#include "SDL.h"

 

Rather than:

 

#include <SDL/SDL.h>
