Default to build SDL without MSVCRT
     1 ==============================================================================
     2 Using the Simple DirectMedia Layer on Atari
     3 ==============================================================================

     5 
     6     If you want to build SDL from sources to create SDL programs on Atari:
     7         see sections I - II.
     8 	
     9     If you want to create SDL programs on Atari using SDL binary build,
    10         download it from my web site (URL at end of this file).
    11 
    12     If you want to configure a program using SDL on Atari,
    13 	    see sections IV - VI.
    14 
    15 
    16 ==============================================================================
    17 I.  Building the Simple DirectMedia Layer libraries:
    18     (This step isn't necessary if you have the SDL binary distribution)
    19 
    20   Do the classic configure, with --disable-shared --enable-static and:
    21 
    22     Tos version (should run everywhere):
    23       --disable-threads
    24     Tos does not support threads.
    25 
    26     MiNT version (maybe Magic, only for multitasking OS):
    27       --disable-pthreads --enable-pth
    28     Mint and Magic may supports threads, so audio can be used with current
    29     devices, like Sun audio, or disk-writing support. Like Tos, interrupt
    30     audio without threads is more suited for Atari machines.
    31 
    32   Then you can make ; make install it.
    33 
    34 ==============================================================================
    35 II. Building the Simple DirectMedia Layer test programs:
    36 
    37   Do the classic configure, then make.
    38 
    39   Run them !
    40 
    41 ==============================================================================
    42 III.  Enjoy! :)
    43 
    44   If you have a project you'd like me to know about, or want to ask questions,
    45   go ahead and join the SDL developer's mailing list by sending e-mail to:
    46 
    47 	sdl-request@libsdl.org
    48 
    49   and put "subscribe" into the subject of the message. Or alternatively you
    50   can use the web interface:
    51 
    52 	http://www.libsdl.org/mailman/listinfo/sdl
    53   
    54 ==============================================================================
    55 IV.  What is supported:
    56 
    57 Keyboard (GEMDOS, BIOS, GEM, Ikbd)
    58 Mouse (XBIOS, GEM, Ikbd)
    59 Video (XBIOS (Fullscreen), GEM (Windowed and Fullscreen))
    60 Timer (VBL vector, GNU pth library)
    61 Joysticks and joypads (Ikbd, Hardware)
    62 Audio (Hardware, XBIOS, GSXB, MCSN, STFA, /dev/audio if threads enabled)
    63 Threads (Multitasking OS only via GNU pth library)
    64 Shared object loader (using LDG library from http://ldg.atari.org/)
    65 Audio CD (MetaDOS)
    66 OpenGL (using Mesa offscreen rendering driver)
    67 
    68 - Dependent driver combinations:
    69 Video   Kbd     Mouse   Timer   Joysticks
    70 xbios   ikbd    ikbd    vbl(2)  ikbd
    71 xbios   gemdos  xbios   vbl(2)  xbios(3)
    72 xbios   bios    xbios   vbl(2)  xbios(3)
    73 gem     gem     gem(1)  vbl(2)  xbios(3)
    74 
    75 Audio   O/S     Misc
    76 dma8    All     Uses MFP Timer A interrupt
    77 xbios	TOS     Uses MFP Timer A interrupt
    78 xbios   MiNT    Uses MiNT thread
    79 xbios   Magic   Disabled
    80 stfa    All     Uses MFP interrupt
    81 mcsn	TOS     Uses MFP Timer A interrupt
    82 mcsn    MiNT    Uses MiNT thread
    83 mcsn    Magic   Disabled
    84 gsxb    All     Uses GSXB callback
    85 
    86 Joypad driver always uses hardware access.
    87 OpenGL driver always uses OSMesa.
    88 
    89 (1) GEM does not report relative mouse motion, so xbios mouse driver is used
    90 to report this type event. Under MiNT, using XBIOS mouse driver is not possible.
    91 
    92 (2) If you build SDL with threads using the GNU pth library, timers are
    93 supported via the pth library.
    94 
    95 (3) Redirecting XBIOS vectors does not work under MiNT, so it is disabled in
    96 this case.
    97 
    98 ==============================================================================
    99 V.  Environment variables:
   100 
   101 SDL_VIDEODRIVER:
   102 	Set to 'xbios' to force xbios video driver
   103 	Set to 'gem' to force gem video driver
   104 
   105 SDL_VIDEO_GL_DRIVER:
   106 	Set to filename to load as OpenGL library, if you use SDL_GL_LoadLibrary()
   107 
   108 SDL_AUDIODRIVER:
   109 	Set to 'mint_gsxb' to force Atari GSXB audio driver
   110 	Set to 'mint_mcsn' to force Atari MCSN audio driver
   111 	Set to 'mint_stfa' to force Atari STFA audio driver
   112 	Set to 'mint_xbios' to force Atari Xbios audio driver
   113 	Set to 'mint_dma8' to force Atari 8 bits DMA audio driver
   114 	Set to 'audio' to force Sun /dev/audio audio driver
   115 	Set to 'disk' to force disk-writing audio driver
   116 
   117 SDL_ATARI_EVENTSDRIVER
   118 	Set to 'ikbd' to force IKBD 6301 keyboard driver
   119 	Set to 'gemdos' to force gemdos keyboard driver
   120 	Set to 'bios' to force bios keyboard driver
   121 
   122 SDL_JOYSTICK_ATARI:
   123 	Use any of these strings in the environment variable to enable or
   124 	disable a joystick:
   125 
   126 	'ikbd-joy1-[on|off]' for IKBD joystick on port 1 (hardware access)
   127 	'xbios-joy1-[on|off]' for IKBD joystick on port 1 (xbios access)
   128 	'porta-pad-[on|off]' for joypad on port A
   129 	'porta-joy0-[on|off]' for joystick 0 on port A
   130 	'porta-joy1-[on|off]' for joystick 1 on port A
   131 	'porta-lp-[on|off]' for lightpen on port A
   132 	'porta-anpad-[on|off]' for analog paddle on port A
   133 	'portb-pad-[on|off]' for joypad on port B
   134 	'portb-joy0-[on|off]' for joystick 0 on port B
   135 	'portb-joy1-[on|off]' for joystick 1 on port B
   136 	'portb-anpad-[on|off]' for analog paddle on port B
   137 
   138 	Default configuration is:
   139 		'ikbd-joy1-on' (if IKBD events driver enabled)
   140 		'xbios-joy1-on' (if gemdos/bios/gem events driver enabled)
   141 		'porta-pad-on portb-pad-on' (if available on the machine)
   142 
   143 	port[a|b]-[pad|joy?|lp|anpad]-* strings are mutually exclusives.
   144 	On such a port, you can only use a joypad OR 1 or 2 joysticks OR
   145 	a lightpen OR an analog paddle. You must disable joypad before
   146 	setting another controller.
   147 
   148 	The second joystick port on IKBD is used by the mouse, so not usable.
   149 	Another problem with the IKBD: mouse buttons and joystick fire buttons
   150 	are wired together at the hardware level, it means:
   151 		port 0                port 0           port 1
   152 		mouse left button  = joystick fire 0 = joystick fire 1
   153 		mouse right button = joystick fire 1 = joystick fire 0
   154 
   155 	Descriptions of joysticks/joypads:
   156 	- Joypads: 1 hat, 17 buttons (Atari Jaguar console-like).
   157 	- Joysticks: 1 hat, 1 button.
   158 	- Lightpen, analog paddles: 2 axis, 2 buttons. The 2 buttons are those
   159 	  affected to 1 button joysticks on the same port.
   160 
   161 ==============================================================================
   162 VI.  More informations about drivers:
   163 
   164 OpenGL:
   165 	The default is to use the Mesa offscreen driver (osmesa.ldg). If you want
   166 	to use an older OpenGL implementation, like mesa_gl.ldg or tiny_gl.ldg,
   167 	your program must use SDL_GL_LoadLibrary() to do so, and retrieve the
   168 	needed function pointers with SDL_LoadFunction(). In all cases, the OpenGL
   169 	context is taken care of by SDL itself, you just have to use gl* functions.
   170 
   171 	However, there is one OpenGL call that has a different prototype in the old
   172 	implementations: glOrtho(). In the old implementations, it has 6 float as
   173 	parameters, in the standard one, it has 6 double parameters. If you want
   174 	to compile testdyngl, or any other SDL program that loads its OpenGL
   175 	library, you must change the glOrtho() prototype used in this program. In
   176 	osmesa.ldg, you can retrieve a glOrtho() with double parameters, by
   177 	searching for the function "glOrtho6d".
   178 
   179 Xbios video:
   180 	Video chip is detected using the _VDO cookie.
   181 	Screen enhancers are not supported, but could be if you know how to
   182 	use them.
   183 
   184 	ST, STE, Mega ST, Mega STE:
   185 		320x200x4 bits, shades of grey, available only for the purpose
   186 		of testing SDL.
   187 	TT:
   188 		320x480x8 and 320x240x8 (software double-lined mode).
   189 	Falcon:
   190 		All modes supported by the current monitor (RVB or VGA).
   191 		BlowUp and Centscreen extended modes, ScreenBlaster 3 current mode.
   192 	Clones and any machine with monochrome monitor:
   193 		Not supported.
   194 
   195 Gem video:
   196 	Automatically used if xbios not available.
   197 
   198 	All machines:
   199 		Only the current resolution, if 8 bits or higher depth.
   200 
   201 IKBD keyboard, mouse and joystick driver:
   202 	Available if _MCH cookie is ST, Mega ST, STE, Mega STE, TT or Falcon.
   203 
   204 	Hades has an IKBD, but xbios is not available for video, so IKBD
   205 	driver is disabled.
   206 
   207 Gemdos and bios keyboard driver:
   208 	Available on all machines.
   209 
   210 Mouse and joystick xbios driver:
   211 	Available on all machines (I think).
   212 
   213 Joypad driver:
   214 	Available if _MCH cookie is STE or Falcon.
   215 
   216 PTH timer driver:
   217 	Available with multitasking OS.
   218 
   219 VBL timer driver:
   220 	Available on all machines (I think).
   221 
   222 Audio drivers:
   223 	Cookies _SND, MCSN, STFA and GSXB used to detect supported audio
   224 	capabilities.
   225 
   226 	STE, Mega STE, TT:
   227 		8 bits DMA (hardware access)
   228 		STFA, MCSN or GSXB driver if installed
   229 	Falcon:
   230 		8 bits DMA (hardware access)
   231 		Xbios functions
   232 		STFA, MCSN or GSXB driver if installed
   233 	Other machines:
