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
Mouse (XBIOS, GEM, Ikbd, /dev/mouse (non working atm, disabled))
59
Video (XBIOS (Fullscreen), GEM (Windowed and Fullscreen))
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)
68
69
70
- Dependent driver combinations:
Video Kbd Mouse Timer Joysticks
xbios ikbd ikbd vbl(2) ikbd
71
72
73
xbios gemdos xbios vbl(2) xbios
xbios bios xbios vbl(2) xbios
gem gem gem(1) vbl(2) xbios
74
75
76
77
Audio O/S Misc
dma8 All Uses MFP Timer A interrupt
xbios TOS Uses MFP Timer A interrupt
78
xbios MiNT Uses MFP Timer A interrupt
79
80
81
82
83
84
85
86
87
xbios Magic Disabled
stfa All Uses MFP interrupt
mcsn TOS Uses MFP Timer A interrupt
mcsn MiNT Uses MiNT thread
mcsn Magic Disabled
gsxb All Uses GSXB callback
Joypad driver always uses hardware access.
OpenGL driver always uses OSMesa.
89
(1) GEM does not report relative mouse motion, so xbios mouse driver is used
90
to report this type event.
91
92
A preliminary driver for /dev/mouse device driver is present, but is disabled
till it can be used with other applications simultaneously.
94
95
96
(2) If you build SDL with threads using the GNU pth library, timers are
supported via the pth library.

==============================================================================
V. Environment variables:
100
101
102
103
SDL_VIDEODRIVER:
Set to 'xbios' to force xbios video driver
Set to 'gem' to force gem video driver
104
105
106
SDL_VIDEO_GL_DRIVER:
Set to filename to load as OpenGL library, if you use SDL_GL_LoadLibrary()
108
109
110
111
112
Set to 'mint_gsxb' to force Atari GSXB audio driver
Set to 'mint_mcsn' to force Atari MCSN audio driver
Set to 'mint_stfa' to force Atari STFA audio driver
Set to 'mint_xbios' to force Atari Xbios audio driver
Set to 'mint_dma8' to force Atari 8 bits DMA audio driver
113
114
115
Set to 'audio' to force Sun /dev/audio audio driver
Set to 'disk' to force disk-writing audio driver
116
117
118
119
120
SDL_ATARI_EVENTSDRIVER
Set to 'ikbd' to force IKBD 6301 keyboard driver
Set to 'gemdos' to force gemdos keyboard driver
Set to 'bios' to force bios keyboard driver
121
122
123
124
SDL_JOYSTICK_ATARI:
Use any of these strings in the environment variable to enable or
disable a joystick:
125
126
'ikbd-joy1-[on|off]' for IKBD joystick on port 1 (hardware access)
'xbios-joy1-[on|off]' for IKBD joystick on port 1 (xbios access)
127
'porta-pad-[on|off]' for joypad and/or teamtap on port A
128
129
130
131
'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
132
'portb-pad-[on|off]' for joypad and/or teamtap on port B
133
134
135
136
137
138
'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)
139
'xbios-joy1-on' (if gemdos/bios/gem events driver enabled)
140
141
142
143
144
145
146
147
'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.
148
149
Another problem with the IKBD: mouse buttons and joystick fire buttons
are wired together at the hardware level, it means:
150
151
152
port 0 port 0 port 1
mouse left button = joystick fire 0 = joystick fire 1
mouse right button = joystick fire 1 = joystick fire 0
154
155
156
157
158
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
175
176
osmesa.ldg, you can retrieve a glOrtho() with double parameters, by
searching for the function "glOrtho6d".
