If you want to build SDL from sources to create SDL programs on Atari:
see sections I - II.
If you want to create SDL programs on Atari using SDL binary build,
download it from my web site (URL at end of this file).
If you want to configure a program using SDL on Atari,
see sections IV - VI.

==============================================================================
I. Building the Simple DirectMedia Layer libraries:
(This step isn't necessary if you have the SDL binary distribution)
Do the classic configure, with --disable-shared --enable-static and:
Tos version (should run everywhere):
23
24
--disable-threads
Tos does not support threads.

MiNT version (maybe Magic, only for multitasking OS):
--disable-pthreads --enable-pth
Mint and Magic may supports threads, so audio can be used with current
devices, like Sun audio, or disk-writing support. Like Tos, interrupt
audio without threads is more suited for Atari machines.
Then you can make ; make install it.
==============================================================================
II. Building the Simple DirectMedia Layer test programs:
Do the classic configure, then make.
Run them !

III. Enjoy! :)
If you have a project you'd like me to know about, or want to ask questions,
go ahead and join the SDL developer's mailing list by sending e-mail to:
sdl-request@libsdl.org
and put "subscribe" into the subject of the message. Or alternatively you
can use the web interface:
http://www.libsdl.org/mailman/listinfo/sdl
==============================================================================
IV. What is supported:
57
Keyboard (GEMDOS, BIOS, GEM, Ikbd)
58
59
Mouse (XBIOS, GEM, Ikbd)
Video (XBIOS (Fullscreen), GEM (Windowed and Fullscreen))
60
Timer (VBL vector, GNU pth library)
61
Joysticks and joypads (Ikbd, Hardware)
62
63
64
65
Audio (Hardware, XBIOS, GSXB, MCSN, STFA, /dev/audio if threads enabled)
Threads (Multitasking OS only via GNU pth library)
Shared object loader (using LDG library from http://ldg.atari.org/)
Audio CD (MetaDOS)
66
OpenGL (using Mesa offscreen rendering driver)
67
68
- Driver combinations:
69
70
71
72
Video Kbd Mouse Timer Joysticks Joypads OpenGL
xbios ikbd ikbd vbl(2) ikbd hardware OSMesa
xbios gemdos xbios vbl(2) xbios hardware OSMesa
xbios bios xbios vbl(2) xbios hardware OSMesa
73
gem gem gem(1) vbl(2) xbios hardware OSMesa
74
75
(1) GEM does not report relative mouse motion, so xbios mouse driver is used
76
to report this type event.
77
78
79
80
(2) If you build SDL with threads using the GNU pth library, timers are
supported via the pth library.

Set to 'gemdos' to force gemdos keyboard driver
Set to 'bios' to force bios keyboard driver
105
106
107
108
SDL_JOYSTICK_ATARI:
Use any of these strings in the environment variable to enable or
disable a joystick:
109
110
'ikbd-joy1-[on|off]' for IKBD joystick on port 1 (hardware access)
'xbios-joy1-[on|off]' for IKBD joystick on port 1 (xbios access)
111
112
113
114
115
116
117
118
119
120
121
122
'porta-pad-[on|off]' for joypad on port A
'porta-joy0-[on|off]' for joystick 0 on port A
'porta-joy1-[on|off]' for joystick 1 on port A
'porta-lp-[on|off]' for lightpen on port A
'porta-anpad-[on|off]' for analog paddle on port A
'portb-pad-[on|off]' for joypad on port B
'portb-joy0-[on|off]' for joystick 0 on port B
'portb-joy1-[on|off]' for joystick 1 on port B
'portb-anpad-[on|off]' for analog paddle on port B
Default configuration is:
'ikbd-joy1-on' (if IKBD events driver enabled)
123
'xbios-joy1-on' (if gemdos/bios/gem events driver enabled)
124
125
126
127
128
129
130
131
'porta-pad-on portb-pad-on' (if available on the machine)
port[a|b]-[pad|joy?|lp|anpad]-* strings are mutually exclusives.
On such a port, you can only use a joypad OR 1 or 2 joysticks OR
a lightpen OR an analog paddle. You must disable joypad before
setting another controller.
The second joystick port on IKBD is used by the mouse, so not usable.
132
133
134
135
136
Another problem with the IKBD: mouse buttons and joystick fire buttons
are wired together at the hardware level, it means:
port 0 port 0 port 1
mouse left button = joystick fire 0 = joystick fire 1
mouse right button = joystick fire 1 = joystick fire 0
137
138
139
140
141
142
Descriptions of joysticks/joypads:
- Joypads: 1 hat, 17 buttons (Atari Jaguar console-like).
- Joysticks: 1 hat, 1 button.
- Lightpen, analog paddles: 2 axis, 2 buttons. The 2 buttons are those
affected to 1 button joysticks on the same port.

OpenGL:
The default is to use the Mesa offscreen driver (osmesa.ldg). If you want
to use an older OpenGL implementation, like mesa_gl.ldg or tiny_gl.ldg,
your program must use SDL_GL_LoadLibrary() to do so, and retrieve the
needed function pointers with SDL_LoadFunction(). In all cases, the OpenGL
context is taken care of by SDL itself, you just have to use gl* functions.
However, there is one OpenGL call that has a different prototype in the old
implementations: glOrtho(). In the old implementations, it has 6 float as
parameters, in the standard one, it has 6 double parameters. If you want
to compile testdyngl, or any other SDL program that loads its OpenGL
library, you must change the glOrtho() prototype used in this program. In
159
160
osmesa.ldg, you can retrieve a glOrtho() with double parameters, by
searching for the function "glOrtho6d".

of testing SDL.
