Simple DirectMedia Layer (SDL) is a cross-platform, free and open source multimedia library. Should not be confused with Security Development Lifecycle.

Simple DirectMedia Layer (SDL) is a cross-platform, free and open source multimedia library written in C that presents a simple interface to various platforms' graphics, sound, and input devices.

From SDL's home page:

Simple DirectMedia Layer is a cross-platform development library designed to provide low level access to audio, keyboard, mouse, joystick, and graphics hardware via OpenGL and Direct3D. It is used by video playback software, emulators, and popular games including Valve's award winning catalog and many Humble Bundle games.

SDL officially supports Windows, Mac OS X, Linux, iOS, and Android. Support for other platforms may be found in the source code.

SDL is written in C, works natively with C++, and there are bindings available for several other languages, including C# and Python.

SDL 2.0 is distributed under the zlib license. This license allows you to use SDL freely in any software.

How do I draw text using OpenGL, SDL and C++?

I heard about SDL_TFF which I read about here but I don't understand how am I supposed to connect the TrueType2 library. Maybe there is something better out there?

The following fluid simulation is a translation of a paper by Stam. Something truly terrible has happened. Each time the program is run with a low DIFF=0.01, the values start off small and then rapidly expand, or "blow up". I have checked the math…

Sleep(1) and SDL_Delay(1) takes 15 ms

I am writing a C++/SDL/OpenGL application, and I have had the most peculiar bug. The game seemed to be working fine with a simple variable timestep. But then the FPS started behaving strangely. I figured out that both Sleep(1) and SDL_Delay(1) take…

What are the benefits of using OpenGL in SDL 2?

I assume that SDL 2 uses OpenGL rendering in the background (or perhaps DirectX if on Windows) and this decision is made by SDl itself. I have seen tutorials which show the use of OpenGL directly in SDL and wondered what benefit, if any would you…

GLUT Alternatives for Haskell?

I don't want to use GLUT, because it does not have a Haskell-like feeling on it. It basically forces you to use IORef and such, because of the callbacks. I've considered GLFW, which seems simple and lets me do the game loop in a monad. But it seems…
