1 Using SDL 1.3 under Windows with the OpenWatcom compiler
2
3 ====================================================
4
5 Prerequisites
6 -------------
7
8 I have done the port under Windows XP Professional with SP2 installed.
9 Windows 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 1.8. 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:\dev\ow18
21 set INCLUDE=%WATCOM%\h;%WATCOM%\h\nt
22 set PATH=%PATH%;%WATCOM%\binnt;%WATCOM%\binw
23 - A recent DirectX SDK. The library needs D3d9.h so at leat the
24 directx 9 sdk is to be used. I used DirectX 10 SDK from August 2009
25 taken directly from the microsoft site.
26 - The SDL 1.3 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 the August 2009
37 DirectX SDK from Microsoft
38 You can also edit the makefile directly and hard code your path to
39 the SDK on your system.
40 I have this in my setup:
41 set DXDIR=..\dx10
42 3) Enter the watcom directory and run
43 wmake sdl
44 4) All tests from the test directory are working and can be built by
45 running
46 wmake tests
47
48 Notes:
49
50 The makefile offers some options to tweak the way the library is built.
51 You have at your disposal the option to build a static (default)
52 library, or a DLL (with tgt=dll). You can also choose whether to build
53 a Release (default) or a Debug version (with build=debug) of the tests
54 and library. Please consult the usage comment at the top of the
55 makefile for usage instructions.
56
57 If you specify a test target (i.e. 'wmake tests' for all tests, or
58 selected targets like 'wmake testgl testvidinfo testoverlay2'), the
59 tests are always freshly compiled and linked. This is done to
60 minimise hassle when switching between library versions (static vs.
61 DLL), because they require subtly different options.
62 Also, the test executables are put directly into the test directory,
63 so they can find their data files. The clean target of the makefile
64 removes the test executables and the SDL.dll file from the test
65 directory.
66
67 To use the library in your own projects with Open Watcom, you can use
68 the way the tests are built as base of your own build environment.
69
70 The library can also be built with the stack calling convention of the
71 compiler (-6s instead of -6r).
72
73 Test applications
74 -----------------
75 $FixME: which test works ? which one compiles ?
76
77 I've tried to make all tests work. The following table gives an overview
78 of the current status.
79
80 Testname Status
81 ~~~~~~~~~~~~~~~ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
82 checkkeys +
83 graywin +
84 loopwave +
85 testalpha +
86 testbitmap +
87 testdyngl +
88 testerror +
89 testfile +
90 testgamma +
91 testgl +
92 testhread +
93 testiconv - (all failed)
94 testkeys +
95 testlock +
96 testoverlay + (needs 'set SDL_VIDEODRIVER=directx')
97 testoverlay2 + (needs 'set SDL_VIDEODRIVER=directx')
98 testpalette +
99 testplatform +
100 testsem +
101 testsprite +
102 testtimer +
103 testver +
104 testvidinfo +
105 testwin ? (fading doesn't seem right)
106 testwm +
107 torturethread +
108 testcdrom +
109 testjoystick not tested
110 threadwin +
111 testcursor +
112

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