re: bug#563. checking in some commented out trace code and a fix so that the in testalpha.c the background only flashes when alpha == 255. The problem that is being fixed is caused by clearing SDL_COPY_RLE_COLORKEY without setting SDL_COPY_RLE_DESIRED in SDL_UnRELSurface.

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

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.
1190 173c063d4f55 OS/2 port! Ryan C. Gordon <icculus@icculus.org> parents: diff changeset	55
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
e3242177fe4a Updated OS/2 build, yay! Sam Lantinga <slouken@libsdl.org> parents: 1190 diff changeset	149 in high priority, which makes sure that there will be enough time for the
