AmigaOS: -= NOT YET SUPPORTED =-
The OpenGL support isn't implemented yet.
SDL_WM_GrabInput() is not implemented.
Does anyone know how to do this? SDL_WM_GrabInput() is designed
to prevent the user from switching input and mouse focus away from
the SDL application.
Continuous relative mouse motion is not implemented.
The AmigaOS port was done by Gabriele.Greco@galactica.it

This is the porting of 1.2.0 version of SDL (the latest stable one)
to AmigaOS/68k.
The AmigaOS code has been removed from SDL, since it had been broken for a
long time and had a few bits of fairly invasive code #ifdef'd into the
SDL core.
All the bugs known of the past version have been corrected. And I've
added all the new SDL features.
However, there is an OS4 version of SDL here:
http://www.rcdrummond.net/amiga/index.html
This version of SDL needs Cybergraphx V3 (r69+) or CyberGraphX V4
and AHI v3+. Probably it works also with P96 or CGXAga, but it's
untested.
And a MorphOS version here:
http://www.lehtoranta.net/powersdl/
This version is available as linked library for SAS/C and GCC, only 68k this
time, a powerup (ppcemu compatible) and a morphos version will be ready quite
soon (i hope).
--ryan.
Implemented:
- 8/16/24/32bit video modes, both fullscreen and windowed.
- Hardware surfaces.
- CGX blitting acceleration.
- CGX colorkey blitting acceleration.
- AHI audio (8/16 bit, with any audio format), always uses unit 0 for now.
- Thread support (maybe not 100% compatible with other implementations)
- Semaphores
- Window resizing and backdrop windows (NEW)
- Joystick/Joypad support.
To do:
- CDRom audio playing support
- OpenGL (A guy was working on it but I've lost his tracks :( )
The SAS/C library is distributed with debug info attached, to strip debug info
simply add STRIPDEBUG argument to the linker.
NOTE: SDL includes debug output using kprintf, to disable it add to your
project a function like this:
void kprintf(char *a,...)
{
}
Otherwise you can redirect the debug to a console window with sushi, sashimi or
similar tools (the default output is the internal serial port).
For info, support, bugfix and other feel free to mail me:
Gabriele Greco (gabriele.greco@aruba.it)
