    If you want to build SDL from sources to create SDL programs on Atari:

    If you want to create SDL programs on Atari using SDL binary build,
patmandin@1083

I.  Building the Simple DirectMedia Layer libraries:
slouken@281
    18
    (This step isn't necessary if you have the SDL binary distribution)
slouken@281
    19
slouken@281
    20
  Do the classic configure, with --disable-shared --enable-static and:
slouken@281
    21
slouken@281
    22
    Tos version (should run everywhere):
slouken@398
    23
      --disable-threads
slouken@398
    24
    Tos does not support threads.
slouken@281
    25
slouken@281
    26
    MiNT version (maybe Magic, only for multitasking OS):
slouken@281
    27
      --disable-pthreads --enable-pth
slouken@281
    28
    Mint and Magic may supports threads, so audio can be used with current
slouken@281
    29
    devices, like Sun audio, or disk-writing support. Like Tos, interrupt
slouken@281
    30
    audio without threads is more suited for Atari machines.
slouken@281
    31
slouken@281
    32
  Then you can make ; make install it.
slouken@281
    33
slouken@281
    34
==============================================================================
slouken@281
    35
II. Building the Simple DirectMedia Layer test programs:
slouken@281
    36
slouken@281
    37
  Do the classic configure, then make.
slouken@281
    38
slouken@281
    39
  Run them !
slouken@281
    40

slouken@281
    45
  go ahead and join the SDL developer's mailing list by sending e-mail to:

IV.  What is supported:
slouken@281
    56
slouken@319
    57
Keyboard (GEMDOS, BIOS, GEM, Ikbd)
slouken@281
    58
Mouse (XBIOS, GEM, Ikbd)
slouken@281
    59
Video (XBIOS (Fullscreen), GEM (Windowed and Fullscreen))
slouken@557
    60
Timer (VBL vector, GNU pth library)
patmandin@963
    61
Joysticks and joypads (Ikbd, Hardware)
patmandin@724
    62
Audio (Hardware, XBIOS, GSXB, MCSN, STFA, /dev/audio if threads enabled)
patmandin@724
    63
Threads (Multitasking OS only via GNU pth library)
patmandin@724
    64
Shared object loader (using LDG library from http://ldg.atari.org/)
patmandin@724
    65
Audio CD (MetaDOS)
patmandin@978
    66
OpenGL (using Mesa offscreen rendering driver)
slouken@281
    67
slouken@281
    68
- Driver combinations:
patmandin@978
    69
Video   Kbd     Mouse   Timer   Joysticks Joypads	OpenGL
patmandin@978
    70
xbios   ikbd    ikbd    vbl(2)  ikbd      hardware	OSMesa
patmandin@978
    71
xbios   gemdos  xbios   vbl(2)  xbios     hardware	OSMesa
patmandin@978
    72
xbios   bios    xbios   vbl(2)  xbios     hardware	OSMesa
patmandin@984
    73
gem     gem     gem(1)  vbl(2)  xbios     hardware	OSMesa
slouken@319
    74
slouken@557
    75
(1) GEM does not report relative mouse motion, so xbios mouse driver is used
slouken@319
    76
to report this type event.
slouken@281
    77
slouken@557
    78
(2) If you build SDL with threads using the GNU pth library, timers are
slouken@557
    79
supported via the pth library.

slouken@281
   104

   105
SDL_JOYSTICK_ATARI:
slouken@302
   106
	Use any of these strings in the environment variable to enable or
slouken@302
   107
	disable a joystick:
slouken@302
   108
slouken@305
   109
	'ikbd-joy1-[on|off]' for IKBD joystick on port 1 (hardware access)
slouken@305
   110
	'xbios-joy1-[on|off]' for IKBD joystick on port 1 (xbios access)
slouken@302
   111
	'porta-pad-[on|off]' for joypad on port A
slouken@302
   112
	'porta-joy0-[on|off]' for joystick 0 on port A
slouken@302
   113
	'porta-joy1-[on|off]' for joystick 1 on port A
slouken@302
   114
	'porta-lp-[on|off]' for lightpen on port A
slouken@302
   115
	'porta-anpad-[on|off]' for analog paddle on port A
slouken@302
   116
	'portb-pad-[on|off]' for joypad on port B
slouken@302
   117
	'portb-joy0-[on|off]' for joystick 0 on port B
slouken@302
   118
	'portb-joy1-[on|off]' for joystick 1 on port B
slouken@302
   119
	'portb-anpad-[on|off]' for analog paddle on port B
slouken@302
   120
slouken@302
   121
	Default configuration is:
slouken@302
   122
		'ikbd-joy1-on' (if IKBD events driver enabled)
slouken@305
   123
		'xbios-joy1-on' (if gemdos/bios/gem events driver enabled)
slouken@302
   124
		'porta-pad-on portb-pad-on' (if available on the machine)
slouken@302
   125
slouken@302
   126
	port[a|b]-[pad|joy?|lp|anpad]-* strings are mutually exclusives.
slouken@302
   127
	On such a port, you can only use a joypad OR 1 or 2 joysticks OR
slouken@302
   128
	a lightpen OR an analog paddle. You must disable joypad before
slouken@302
   129
	setting another controller.
slouken@302
   130
slouken@302
   131
	The second joystick port on IKBD is used by the mouse, so not usable.
patmandin@1087
   132
	Another problem with the IKBD: mouse buttons and joystick fire buttons
patmandin@1087
   133
	are wired together at the hardware level, it means:
patmandin@1087
   134
		port 0					port 0				port 1
patmandin@1087
   135
		mouse left button	=	joystick fire 0	=	joystick fire 1
patmandin@1087
   136
		mouse right button	=	joystick fire 1	=	joystick fire 0
slouken@302
   137
patmandin@963
   138
	Descriptions of joysticks/joypads:
patmandin@963
   139
	- Joypads: 1 hat, 17 buttons (Atari Jaguar console-like).
patmandin@963
   140
	- Joysticks: 1 hat, 1 button.
patmandin@963
   141
	- Lightpen, analog paddles: 2 axis, 2 buttons. The 2 buttons are those
patmandin@963
   142
	  affected to 1 button joysticks on the same port.

VI.  More informations about drivers:
slouken@319
   146
patmandin@1007
   147
OpenGL:
patmandin@1007
   148
	The default is to use the Mesa offscreen driver (osmesa.ldg). If you want
patmandin@1007
   149
	to use an older OpenGL implementation, like mesa_gl.ldg or tiny_gl.ldg,
patmandin@1007
   150
	your program must use SDL_GL_LoadLibrary() to do so, and retrieve the
patmandin@1007
   151
	needed function pointers with SDL_LoadFunction(). In all cases, the OpenGL
patmandin@1007
   152
	context is taken care of by SDL itself, you just have to use gl* functions.
patmandin@1007
   153
patmandin@1007
   154
	However, there is one OpenGL call that has a different prototype in the old
patmandin@1007
   155
	implementations: glOrtho(). In the old implementations, it has 6 float as
patmandin@1007
   156
	parameters, in the standard one, it has 6 double parameters. If you want
patmandin@1007
   157
	to compile testdyngl, or any other SDL program that loads its OpenGL
patmandin@1007
   158
	library, you must change the glOrtho() prototype used in this program. In
patmandin@1064
   159
	osmesa.ldg, you can retrieve a glOrtho() with double parameters, by
patmandin@1064
   160
	searching for the function "glOrtho6d".
patmandin@1007
   161
slouken@319
   162

slouken@319
   163
	Video chip is detected using the _VDO cookie.

slouken@319
   165
	use them.
