2 Using SDL under Windows with the OpenWatcom compiler
3 ====================================================
4
5 Prerequisites
6 -------------
7
8 I have done the port under Windows XP Home with SP2 installed. Windows
9 2000 should also be working. I'm not so sure about ancient Windows NT,
10 since only DirectX 3 is available there. Building should be possible,
11 but running the compiled applications will probalbly fail with
12 SDL_VIDEODRIVER=directx. The windib driver should work, though.
13
14 To compile and use the SDL with Open Watcom you will need the following:
15 - Open Watcom compiler. I used version 1.5. The environment variables
16 PATH, WATCOM and INCLUDE need to be set appropriately - please consult
17 the OpenWatcom documentation and instructions given during the
18 installation of the compiler.
19 My setup looks like this in owvars.bat:
20 set WATCOM=C:\watcom
21 set INCLUDE=%WATCOM%\h;%WATCOM%\h\nt
22 set PATH=%PATH%;%WATCOM%\binnt;%WATCOM%\binw
23 - A fairly recent DirectX SDK. The original unmodified DX8 SDK works, as
24 well as the minimal DirectX 7 SDK from the Allegro download site
25 (<http://alleg.sourceforge.net/files/dx70_min.zip>).
26 - The SDL sources from Subversion
27 - The file Watcom-Win32.zip (now available in Subversion)
28

30 Building the Library
31 --------------------
32
33 1) In the SDL base directory extract the archive Watcom-Win32.zip. This
34 creates a subdirectory named 'watcom'.
35 2) The makefile expects the environment variable DXDIR to be set to the
36 base directory of a DirectX SDK. I have tried a stock DX8 SDK from
37 Microsoft as well as the minimal DirectX 7 SDK from the Allegro
38 download site.
39 You can also edit the makefile directly and hard code your path to
40 the SDK on your system.
41 I have this in my setup:
42 set DXDIR=D:\devel\DX8_SDK
43 3) Enter the watcom directory and run
44 wmake sdl
45 4) All tests from the test directory are working and can be built by
46 running
47 wmake tests
48
49 Notes:
50
51 The makefile offers some options to tweak the way the library is built.
52 You have at your disposal the option to build a static (default)
53 library, or a DLL (with tgt=dll). You can also choose whether to build
54 a Release (default) or a Debug version (with build=debug) of the tests
55 and library. Please consult the usage comment at the top of the
56 makefile for usage instructions.
57
58 If you specify a test target (i.e. 'wmake tests' for all tests, or
59 selected targets like 'wmake testgl testvidinfo testoverlay2'), the
60 tests are always freshly compiled and linked. This is done to
61 minimise hassle when switching between library versions (static vs.
62 DLL), because they require subtly different options.
63 Also, the test executables are put directly into the test directory,
64 so they can find their data files. The clean target of the makefile
65 removes the test executables and the SDL.dll file from the test
66 directory.
67
68 To use the library in your own projects with Open Watcom, you can use
69 the way the tests are built as base of your own build environment.

72 Test applications
73 -----------------
74
75 I've tried to make all tests work. The following table gives an overview
76 of the current status.

79 ~~~~~~~~~~~~~~~ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
80 checkkeys +
81 graywin +

91 testiconv - (all failed)

107 testjoystick not tested

111 TODO
112 ----
113
114 There is room for further improvement:
115 - Test joystick functionality.
116 - Investigate fading issue in 'testwin' test.
117 - Fix the UTF-8 support.
118 - Adapt the makefile/object file list to support more target systems
119 - Use "#pragma aux" syntax for the CPU info functions.
