| 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 | |
| 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. | |

| 115 TODO | |
| 116 ---- | |
| 117 | |
| 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. | |
| 124 | |
