SDL
Introduction
The Haskell packages hsSDL2 and sdl2 are bindings to the C library libSDL
From Wikipedia:
Simple DirectMedia Layer (SDL) is a cross-platform, free and open source software multimedia library written in C, that presents a simple interface to various platforms' graphics, sound, and input devices. Software developers use it to write computer games or other multimedia applications that can run on many operating systems [...] .
The SDL introduction page lists the operating systems:
- Windows
- Mac OS X
- Linux
- iOS
- Android
Installation
For installation of hsSDL2 on Windows, see SDL/Windows.

Problems
Haskell-SDL with Mac OS X
There are some issues with the Haskell SDL bindings and Mac OS X, notably linking problems that result in an error such as:
Linking test ...
Undefined symbols:
"_SDL_main", referenced from:
-[SDLMain applicationDidFinishLaunching:] in libSDLmain.a(SDLMain.o)
ld: symbol(s) not found
collect2: ld returned 1 exit status
In the SDL bindings' MACOSX file, there is some mention of a code example that shows how to solve this. Unfortunately, the Darcs repository where this code resides is down. After asking Nick Alexander, who was mentioned in the MACOSX file, he referred to the following work by Audrey Tang, where the Main-file trick for making this compile can still be found: [1]
