2 Using SDL under Windows with the OpenWatcom compiler
|
|
|
3 ====================================================
|

|
|
|
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
|
|
|
29
|
|
|
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.

75 I've tried to make all tests work. The following table gives an overview

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.
