Based on SDL 1.2.14
The sdl-1.2.14-s60-2.4.5_armv5.sisx is compiled using S60 5th edition SDK,
but the binary works in 3.x, 5.x and Symbian^3 devices.
sdl-1.2.14-s60-2.4.5_hwaplugin_armv5.sisx is compiled Symbian^3 SDK Beta and
is optional component that utilizes hardware accelator for final on screen
blitting. That provides some improvemet on performance. That binary is not
compatible with older devices, Symbian^3 SDK code is not downwards compatible!
Download that from libsdl.org and extract on your developement directory.
Extract sdl-1.2.14-s60-2.4.5.zip on your developement directory.
Run install from SDL_Install
SDL-1.2.14/symbian/configure.bat rebuils SDK and creates sisx packages.
Binaries are in SDL-1.2.14/symbian/install folder to copy into your phone.
