I recently commented on how Symbian libraries are starting to appear. SDL is a new Symbian multimedia library that provides low level access to audio, keyboard, 3D hardware via OpenGL and a 2D frame buffer.
SDL is particularly useful for cross platform development…
"SDL supports Linux, Windows, Windows CE, BeOS, MacOS, Mac OS X, FreeBSD, NetBSD, OpenBSD, BSD/OS, Solaris, IRIX, and QNX. "
SDL is great for writing platform independent games. In fact, Doom for S60 uses this library.
