Adjusted default choice of audio driver.
If a driver can definitely see available devices, it is chosen. Otherwise,
we'll take the first driver that initializes but saw no devices...this might
be because it can't enumerate them, or there really aren't any available.
This prevents the dsp driver from hogging control when there are no /dev/dsp*
nodes (for example, on a Linux box with ALSA and no OSS emulation).

| 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 | |
