Adjusted default choice of audio driver. If a driver can definitely see available devices, it is chosen. Otherwise, we'll take the first driver that initializes but saw no devices...this might be because it can't enumerate them, or there really aren't any available. This prevents the dsp driver from hogging control when there are no /dev/dsp* nodes (for example, on a Linux box with ALSA and no OSS emulation).

173c063d4f55 OS/2 port! Ryan C. Gordon <icculus@icculus.org> parents: diff changeset	9 1. How to compile?
173c063d4f55 OS/2 port! Ryan C. Gordon <icculus@icculus.org> parents: diff changeset	10 ------------------
173c063d4f55 OS/2 port! Ryan C. Gordon <icculus@icculus.org> parents: diff changeset	11
173c063d4f55 OS/2 port! Ryan C. Gordon <icculus@icculus.org> parents: diff changeset	12 To compile this, you'll need the followings installed:
173c063d4f55 OS/2 port! Ryan C. Gordon <icculus@icculus.org> parents: diff changeset	13 - The OS/2 Developer's Toolkit
173c063d4f55 OS/2 port! Ryan C. Gordon <icculus@icculus.org> parents: diff changeset	14 - The OpenWatcom compiler
173c063d4f55 OS/2 port! Ryan C. Gordon <icculus@icculus.org> parents: diff changeset	15 (http://www.openwatcom.org)

1758 45138f6a2fb5 Updated OS/2 project files Sam Lantinga <slouken@libsdl.org> parents: 1442 diff changeset	19 First of all, you have to unzip the Watcom-OS2.zip file. This will result in a
45138f6a2fb5 Updated OS/2 project files Sam Lantinga <slouken@libsdl.org> parents: 1442 diff changeset	20 file called "makefile" and a file called "setvars.cmd" in this folder (and some
45138f6a2fb5 Updated OS/2 project files Sam Lantinga <slouken@libsdl.org> parents: 1442 diff changeset	21 more files...).
1442 e3242177fe4a Updated OS/2 build, yay! Sam Lantinga <slouken@libsdl.org> parents: 1190 diff changeset	22
1190 173c063d4f55 OS/2 port! Ryan C. Gordon <icculus@icculus.org> parents: diff changeset	23 Please edit the second, fourth and fifth lines of setvars.cmd file
173c063d4f55 OS/2 port! Ryan C. Gordon <icculus@icculus.org> parents: diff changeset	24 to set the folders where the toolkit, the OW compiler and the FSLib are.
173c063d4f55 OS/2 port! Ryan C. Gordon <icculus@icculus.org> parents: diff changeset	25 You won't need NASM yet (The Netwide Assembler), you can leave that line.
173c063d4f55 OS/2 port! Ryan C. Gordon <icculus@icculus.org> parents: diff changeset	26 Run setvars.cmd, and you should get a shell in which you can
173c063d4f55 OS/2 port! Ryan C. Gordon <icculus@icculus.org> parents: diff changeset	27 compile SDL.
173c063d4f55 OS/2 port! Ryan C. Gordon <icculus@icculus.org> parents: diff changeset	28
1758 45138f6a2fb5 Updated OS/2 project files Sam Lantinga <slouken@libsdl.org> parents: 1442 diff changeset	29 Check the "makefile" file. There is a line in there which determines if the
45138f6a2fb5 Updated OS/2 project files Sam Lantinga <slouken@libsdl.org> parents: 1442 diff changeset	30 resulting SDL.DLL will be a 'debug' or a 'release' build. The 'debug' version
45138f6a2fb5 Updated OS/2 project files Sam Lantinga <slouken@libsdl.org> parents: 1442 diff changeset	31 is full of printf()'s, so if something goes wrong, its output can help a lot
45138f6a2fb5 Updated OS/2 project files Sam Lantinga <slouken@libsdl.org> parents: 1442 diff changeset	32 for debugging.
1190 173c063d4f55 OS/2 port! Ryan C. Gordon <icculus@icculus.org> parents: diff changeset	33
1758 45138f6a2fb5 Updated OS/2 project files Sam Lantinga <slouken@libsdl.org> parents: 1442 diff changeset	34 Then run "wmake".
1895 c121d94672cb SDL 1.2 is moving to a branch, and SDL 1.3 is becoming the head. Sam Lantinga <slouken@libsdl.org> parents: 1850 diff changeset	35 This should create the SDL.DLL and the corresponding SDL.LIB file here.
1190 173c063d4f55 OS/2 port! Ryan C. Gordon <icculus@icculus.org> parents: diff changeset	36
173c063d4f55 OS/2 port! Ryan C. Gordon <icculus@icculus.org> parents: diff changeset	37 To test applications, it's a good idea to use the 'debug' build of SDL, and
173c063d4f55 OS/2 port! Ryan C. Gordon <icculus@icculus.org> parents: diff changeset	38 redirect the standard output and standard error output to files, to see what
173c063d4f55 OS/2 port! Ryan C. Gordon <icculus@icculus.org> parents: diff changeset	39 happens internally in SDL.
173c063d4f55 OS/2 port! Ryan C. Gordon <icculus@icculus.org> parents: diff changeset	40 (like: testsprite >stdout.txt 2>stderr.txt)
173c063d4f55 OS/2 port! Ryan C. Gordon <icculus@icculus.org> parents: diff changeset	41
1758 45138f6a2fb5 Updated OS/2 project files Sam Lantinga <slouken@libsdl.org> parents: 1442 diff changeset	42 To rebuild SDL, use the following commands in this folder:
45138f6a2fb5 Updated OS/2 project files Sam Lantinga <slouken@libsdl.org> parents: 1442 diff changeset	43 wmake clean
45138f6a2fb5 Updated OS/2 project files Sam Lantinga <slouken@libsdl.org> parents: 1442 diff changeset	44 wmake
1190 173c063d4f55 OS/2 port! Ryan C. Gordon <icculus@icculus.org> parents: diff changeset	45

173c063d4f55 OS/2 port! Ryan C. Gordon <icculus@icculus.org> parents: diff changeset	47
173c063d4f55 OS/2 port! Ryan C. Gordon <icculus@icculus.org> parents: diff changeset	48 2. How to compile the testapps?
173c063d4f55 OS/2 port! Ryan C. Gordon <icculus@icculus.org> parents: diff changeset	49 -------------------------------
173c063d4f55 OS/2 port! Ryan C. Gordon <icculus@icculus.org> parents: diff changeset	50
1895 c121d94672cb SDL 1.2 is moving to a branch, and SDL 1.3 is becoming the head. Sam Lantinga <slouken@libsdl.org> parents: 1850 diff changeset	51 Once you have SDL.DLL compiled, navigate into the 'test' folder, copy in there
c121d94672cb SDL 1.2 is moving to a branch, and SDL 1.3 is becoming the head. Sam Lantinga <slouken@libsdl.org> parents: 1850 diff changeset	52 the newly built SDL.DLL, and copy in there FSLib.DLL.

1758 45138f6a2fb5 Updated OS/2 project files Sam Lantinga <slouken@libsdl.org> parents: 1442 diff changeset	54 Then run "wmake" in there to compile some of the testapps.

173c063d4f55 OS/2 port! Ryan C. Gordon <icculus@icculus.org> parents: diff changeset	56
173c063d4f55 OS/2 port! Ryan C. Gordon <icculus@icculus.org> parents: diff changeset	57
173c063d4f55 OS/2 port! Ryan C. Gordon <icculus@icculus.org> parents: diff changeset	58 3. What is missing?
173c063d4f55 OS/2 port! Ryan C. Gordon <icculus@icculus.org> parents: diff changeset	59 -------------------
173c063d4f55 OS/2 port! Ryan C. Gordon <icculus@icculus.org> parents: diff changeset	60
173c063d4f55 OS/2 port! Ryan C. Gordon <icculus@icculus.org> parents: diff changeset	61 The following things are missing from this SDL implementation:
173c063d4f55 OS/2 port! Ryan C. Gordon <icculus@icculus.org> parents: diff changeset	62 - MMX, SSE and 3DNOW! optimized video blitters?
173c063d4f55 OS/2 port! Ryan C. Gordon <icculus@icculus.org> parents: diff changeset	63 - HW Video surfaces
173c063d4f55 OS/2 port! Ryan C. Gordon <icculus@icculus.org> parents: diff changeset	64 - OpenGL support
173c063d4f55 OS/2 port! Ryan C. Gordon <icculus@icculus.org> parents: diff changeset	65
173c063d4f55 OS/2 port! Ryan C. Gordon <icculus@icculus.org> parents: diff changeset	66
173c063d4f55 OS/2 port! Ryan C. Gordon <icculus@icculus.org> parents: diff changeset	67
173c063d4f55 OS/2 port! Ryan C. Gordon <icculus@icculus.org> parents: diff changeset	68 4. Special Keys / Full-Screen support
173c063d4f55 OS/2 port! Ryan C. Gordon <icculus@icculus.org> parents: diff changeset	69 -------------------------------------
173c063d4f55 OS/2 port! Ryan C. Gordon <icculus@icculus.org> parents: diff changeset	70
173c063d4f55 OS/2 port! Ryan C. Gordon <icculus@icculus.org> parents: diff changeset	71 There are two special hot-keys implemented:
173c063d4f55 OS/2 port! Ryan C. Gordon <icculus@icculus.org> parents: diff changeset	72 - Alt+Home switches between fullscreen and windowed mode
173c063d4f55 OS/2 port! Ryan C. Gordon <icculus@icculus.org> parents: diff changeset	73 - Alt+End simulates closing the window (can be used as a Panic key)
173c063d4f55 OS/2 port! Ryan C. Gordon <icculus@icculus.org> parents: diff changeset	74 Only the LEFT Alt key will work.
173c063d4f55 OS/2 port! Ryan C. Gordon <icculus@icculus.org> parents: diff changeset	75
173c063d4f55 OS/2 port! Ryan C. Gordon <icculus@icculus.org> parents: diff changeset	76
173c063d4f55 OS/2 port! Ryan C. Gordon <icculus@icculus.org> parents: diff changeset	77
173c063d4f55 OS/2 port! Ryan C. Gordon <icculus@icculus.org> parents: diff changeset	78 5. Joysticks on SDL/2
173c063d4f55 OS/2 port! Ryan C. Gordon <icculus@icculus.org> parents: diff changeset	79 ---------------------
173c063d4f55 OS/2 port! Ryan C. Gordon <icculus@icculus.org> parents: diff changeset	80
173c063d4f55 OS/2 port! Ryan C. Gordon <icculus@icculus.org> parents: diff changeset	81 The Joystick detection only works for standard joysticks (2 buttons, 2 axes
173c063d4f55 OS/2 port! Ryan C. Gordon <icculus@icculus.org> parents: diff changeset	82 and the like). Therefore, if you use a non-standard joystick, you should
173c063d4f55 OS/2 port! Ryan C. Gordon <icculus@icculus.org> parents: diff changeset	83 specify its features in the SDL_OS2_JOYSTICK environment variable in a batch
173c063d4f55 OS/2 port! Ryan C. Gordon <icculus@icculus.org> parents: diff changeset	84 file or CONFIG.SYS, so SDL applications can provide full capability to your
173c063d4f55 OS/2 port! Ryan C. Gordon <icculus@icculus.org> parents: diff changeset	85 device. The syntax is:
173c063d4f55 OS/2 port! Ryan C. Gordon <icculus@icculus.org> parents: diff changeset	86
173c063d4f55 OS/2 port! Ryan C. Gordon <icculus@icculus.org> parents: diff changeset	87 SET SDL_OS2_JOYSTICK=[JOYSTICK_NAME] [AXES] [BUTTONS] [HATS] [BALLS]
173c063d4f55 OS/2 port! Ryan C. Gordon <icculus@icculus.org> parents: diff changeset	88
173c063d4f55 OS/2 port! Ryan C. Gordon <icculus@icculus.org> parents: diff changeset	89 So, it you have a Gravis GamePad with 4 axes, 2 buttons, 2 hats and 0 balls,
173c063d4f55 OS/2 port! Ryan C. Gordon <icculus@icculus.org> parents: diff changeset	90 the line should be:
173c063d4f55 OS/2 port! Ryan C. Gordon <icculus@icculus.org> parents: diff changeset	91
173c063d4f55 OS/2 port! Ryan C. Gordon <icculus@icculus.org> parents: diff changeset	92 SET SDL_OS2_JOYSTICK=Gravis_GamePad 4 2 2 0
173c063d4f55 OS/2 port! Ryan C. Gordon <icculus@icculus.org> parents: diff changeset	93
173c063d4f55 OS/2 port! Ryan C. Gordon <icculus@icculus.org> parents: diff changeset	94 If you want to add spaces in your joystick name, just surround it with
173c063d4f55 OS/2 port! Ryan C. Gordon <icculus@icculus.org> parents: diff changeset	95 quotes or double-quotes:
173c063d4f55 OS/2 port! Ryan C. Gordon <icculus@icculus.org> parents: diff changeset	96
173c063d4f55 OS/2 port! Ryan C. Gordon <icculus@icculus.org> parents: diff changeset	97 SET SDL_OS2_JOYSTICK='Gravis GamePad' 4 2 2 0
173c063d4f55 OS/2 port! Ryan C. Gordon <icculus@icculus.org> parents: diff changeset	98
173c063d4f55 OS/2 port! Ryan C. Gordon <icculus@icculus.org> parents: diff changeset	99 or
173c063d4f55 OS/2 port! Ryan C. Gordon <icculus@icculus.org> parents: diff changeset	100
173c063d4f55 OS/2 port! Ryan C. Gordon <icculus@icculus.org> parents: diff changeset	101 SET SDL_OS2_JOYSTICK="Gravis GamePad" 4 2 2 0
173c063d4f55 OS/2 port! Ryan C. Gordon <icculus@icculus.org> parents: diff changeset	102
173c063d4f55 OS/2 port! Ryan C. Gordon <icculus@icculus.org> parents: diff changeset	103 Notive However that Balls and Hats are not supported under OS/2, and the
173c063d4f55 OS/2 port! Ryan C. Gordon <icculus@icculus.org> parents: diff changeset	104 value will be ignored... but it is wise to define these correctly because
173c063d4f55 OS/2 port! Ryan C. Gordon <icculus@icculus.org> parents: diff changeset	105 in the future those can be supported.
173c063d4f55 OS/2 port! Ryan C. Gordon <icculus@icculus.org> parents: diff changeset	106 Also the number of buttons is limited to 2 when using two joysticks,
173c063d4f55 OS/2 port! Ryan C. Gordon <icculus@icculus.org> parents: diff changeset	107 4 when using one joystick with 4 axes, 6 when using a joystick with 3 axes
173c063d4f55 OS/2 port! Ryan C. Gordon <icculus@icculus.org> parents: diff changeset	108 and 8 when using a joystick with 2 axes. Notice however these are limitations
173c063d4f55 OS/2 port! Ryan C. Gordon <icculus@icculus.org> parents: diff changeset	109 of the Joystick Port hardware, not OS/2.
173c063d4f55 OS/2 port! Ryan C. Gordon <icculus@icculus.org> parents: diff changeset	110
173c063d4f55 OS/2 port! Ryan C. Gordon <icculus@icculus.org> parents: diff changeset	111
173c063d4f55 OS/2 port! Ryan C. Gordon <icculus@icculus.org> parents: diff changeset	112
1442 e3242177fe4a Updated OS/2 build, yay! Sam Lantinga <slouken@libsdl.org> parents: 1190 diff changeset	113 6. Proportional windows
e3242177fe4a Updated OS/2 build, yay! Sam Lantinga <slouken@libsdl.org> parents: 1190 diff changeset	114 -----------------------
e3242177fe4a Updated OS/2 build, yay! Sam Lantinga <slouken@libsdl.org> parents: 1190 diff changeset	115
e3242177fe4a Updated OS/2 build, yay! Sam Lantinga <slouken@libsdl.org> parents: 1190 diff changeset	116 For some SDL applications it can be handy to have proportional windows, so
e3242177fe4a Updated OS/2 build, yay! Sam Lantinga <slouken@libsdl.org> parents: 1190 diff changeset	117 the windows will keep their aspect ratio when resized.
e3242177fe4a Updated OS/2 build, yay! Sam Lantinga <slouken@libsdl.org> parents: 1190 diff changeset	118 This can be achieved in two ways:
e3242177fe4a Updated OS/2 build, yay! Sam Lantinga <slouken@libsdl.org> parents: 1190 diff changeset	119
e3242177fe4a Updated OS/2 build, yay! Sam Lantinga <slouken@libsdl.org> parents: 1190 diff changeset	120 - Before starting the given SDL application, set the
e3242177fe4a Updated OS/2 build, yay! Sam Lantinga <slouken@libsdl.org> parents: 1190 diff changeset	121 SDL_USE_PROPORTIONAL_WINDOW environment variable to something, e.g.:
e3242177fe4a Updated OS/2 build, yay! Sam Lantinga <slouken@libsdl.org> parents: 1190 diff changeset	122
e3242177fe4a Updated OS/2 build, yay! Sam Lantinga <slouken@libsdl.org> parents: 1190 diff changeset	123 SET SDL_USE_PROPORTIONAL_WINDOW=1
e3242177fe4a Updated OS/2 build, yay! Sam Lantinga <slouken@libsdl.org> parents: 1190 diff changeset	124 dosbox.exe
e3242177fe4a Updated OS/2 build, yay! Sam Lantinga <slouken@libsdl.org> parents: 1190 diff changeset	125
e3242177fe4a Updated OS/2 build, yay! Sam Lantinga <slouken@libsdl.org> parents: 1190 diff changeset	126 - If you have a HOME environment variable set, then SDL will look for a file
e3242177fe4a Updated OS/2 build, yay! Sam Lantinga <slouken@libsdl.org> parents: 1190 diff changeset	127 in there called ".sdl.proportionals". If that file contains the name of the
e3242177fe4a Updated OS/2 build, yay! Sam Lantinga <slouken@libsdl.org> parents: 1190 diff changeset	128 currently running SDL executable, then that process will have proportional
e3242177fe4a Updated OS/2 build, yay! Sam Lantinga <slouken@libsdl.org> parents: 1190 diff changeset	129 windows automatically.
e3242177fe4a Updated OS/2 build, yay! Sam Lantinga <slouken@libsdl.org> parents: 1190 diff changeset	130
e3242177fe4a Updated OS/2 build, yay! Sam Lantinga <slouken@libsdl.org> parents: 1190 diff changeset	131 Please note that this file is created automatically with default values
e3242177fe4a Updated OS/2 build, yay! Sam Lantinga <slouken@libsdl.org> parents: 1190 diff changeset	132 at the first run.

e3242177fe4a Updated OS/2 build, yay! Sam Lantinga <slouken@libsdl.org> parents: 1190 diff changeset	137 ----------------------------
e3242177fe4a Updated OS/2 build, yay! Sam Lantinga <slouken@libsdl.org> parents: 1190 diff changeset	138
e3242177fe4a Updated OS/2 build, yay! Sam Lantinga <slouken@libsdl.org> parents: 1190 diff changeset	139 Audio effects are one of the most important features in games. Creating audio
e3242177fe4a Updated OS/2 build, yay! Sam Lantinga <slouken@libsdl.org> parents: 1190 diff changeset	140 effects in sync with the game and without hickups and pauses in the audio are
e3242177fe4a Updated OS/2 build, yay! Sam Lantinga <slouken@libsdl.org> parents: 1190 diff changeset	141 very important things.
e3242177fe4a Updated OS/2 build, yay! Sam Lantinga <slouken@libsdl.org> parents: 1190 diff changeset	142
e3242177fe4a Updated OS/2 build, yay! Sam Lantinga <slouken@libsdl.org> parents: 1190 diff changeset	143 However there are multithreaded SDL applications that have tight loops as their
e3242177fe4a Updated OS/2 build, yay! Sam Lantinga <slouken@libsdl.org> parents: 1190 diff changeset	144 main logic loop. This kills performance in OS/2, and takes too much CPU from
e3242177fe4a Updated OS/2 build, yay! Sam Lantinga <slouken@libsdl.org> parents: 1190 diff changeset	145 other threads in the same process, for example from the thread to create the
e3242177fe4a Updated OS/2 build, yay! Sam Lantinga <slouken@libsdl.org> parents: 1190 diff changeset	146 sound effects.
e3242177fe4a Updated OS/2 build, yay! Sam Lantinga <slouken@libsdl.org> parents: 1190 diff changeset	147
e3242177fe4a Updated OS/2 build, yay! Sam Lantinga <slouken@libsdl.org> parents: 1190 diff changeset	148 For this reason, the OS/2 port of SDL can be instructed to run the audio thread
