2 Using SDL 1.3 under Windows with the OpenWatcom compiler
4 ====================================================
9 I have done the port under Windows XP Professional with SP2 installed.
10 Windows 2000 should also be working. I'm not so sure about ancient Windows NT,
11 since only DirectX 3 is available there. Building should be possible,
12 but running the compiled applications will probalbly fail with
13 SDL_VIDEODRIVER=directx. The windib driver should work, though.
15 To compile and use the SDL with Open Watcom you will need the following:
16 - Open Watcom compiler. I used version 1.8. The environment variables
17 PATH, WATCOM and INCLUDE need to be set appropriately - please consult
18 the OpenWatcom documentation and instructions given during the
19 installation of the compiler.
20 My setup looks like this in owvars.bat:
21 set WATCOM=C:\dev\ow18
22 set INCLUDE=%WATCOM%\h;%WATCOM%\h\nt
23 set PATH=%PATH%;%WATCOM%\binnt;%WATCOM%\binw
24 - A recent DirectX SDK. The library needs D3d9.h so at leat the
25 directx 9 sdk is to be used. I used DirectX 10 SDK from August 2009
26 taken directly from the microsoft site.
27 - The SDL 1.3 sources from Subversion
28 - The file Watcom-Win32.zip (now available in Subversion)
34 1) In the SDL base directory extract the archive Watcom-Win32.zip. This
35 creates a subdirectory named 'watcom'.
36 2) The makefile expects the environment variable DXDIR to be set to the
37 base directory of a DirectX SDK. I have tried the August 2009
38 DirectX SDK from Microsoft
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:
43 3) Enter the watcom directory and run
45 4) All tests from the test directory are working and can be built by
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.
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
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.
71 The library can also be built with the stack calling convention of the
72 compiler (-6s instead of -6r).
76 $FixME: which test works ? which one compiles ?
78 I've tried to make all tests work. The following table gives an overview
79 of the current status.
82 ~~~~~~~~~~~~~~~ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
94 testiconv - (all failed)
97 testoverlay + (needs 'set SDL_VIDEODRIVER=directx')
98 testoverlay2 + (needs 'set SDL_VIDEODRIVER=directx')
106 testwin ? (fading doesn't seem right)
110 testjoystick not tested
118 There is room for further improvement:
119 - Test joystick functionality.
120 - Investigate fading issue in 'testwin' test.
121 - Fix the UTF-8 support.
122 - Adapt the makefile/object file list to support more target systems
123 - Use "#pragma aux" syntax for the CPU info functions.
