Fixed bug #84

Subject: [SDL] no software surfaces with svgalib driver?
Hi,
I noticed that the SDL (1.2.9) svgalib driver only makes use of linear
addressable (framebuffer) video modes. On older systems (like one of
mine), linear addressable modes are often not available.
Especially for cards with VESA VBE < 2.0 the svgalib vesa driver is
unusable, since VESA only supports framebuffering for VBE 2.0 and later.
The changes necessary to add support for software surfaces seem to be
relatively small. I only had to hack src/video/svga/SDL_svgavideo.c (see
attached patch). The code worked fine for me, but it is no more than a
proof of concept and should be reviewed (probably has a memory leak when
switching modes). It also uses the vgagl library (included in the
svgalib package) and needs to be linked against it.

| 3 Using the Simple DirectMedia Layer with MacOS 7,8,9 on PPC | |
| 4 ============================================================================== | |
| 5 | |
| 6 These instructions are for people using the Apple MPW environment: | |
| 7 http://developer.apple.com/tools/mpw-tools/ | |
| 8 | |
| 9 CodeWarrior projects are available in the CWprojects directory. | |
| 10 | |
| 11 ============================================================================== | |
| 12 I. Building the Simple DirectMedia Layer libraries: | |
| 13 (This step isn't necessary if you have the SDL binary distribution) | |
| 14 | |
| 15 First, unpack the MPWmake.sea.hqx archive and move SDL.make into the | |
| 16 SDL directory. | |
| 17 | |
| 18 Start MPW | |
| 19 | |
| 20 Set the current directory within MPW to the SDL toplevel directory. | |
| 21 | |
| 22 Build "SDL" (Type Command-B and enter "SDL" in the dialog) | |
| 23 | |
| 24 If everything compiles successfully, you now have the PPC libraries | |
| 25 "SDL" and "SDLmain.o" in the 'lib' subdirectory. | |
| 26 | |
| 27 ============================================================================== | |
| 28 II. Building the Simple DirectMedia Layer test programs: | |
| 29 | |
| 30 First, unpack the MPWmake.sea.hqx archive, move the new rsrc directory to | |
| 31 the main SDL directory, and move the makefiles in the new test subdirectory | |
| 32 to the SDL 'test' subdirectory. | |
| 33 | |
| 34 Start MPW | |
| 35 | |
| 36 Set the current directory within MPW to the SDL 'test' subdirectory. | |
| 37 | |
| 38 Build the programs that have an associated MPW makefile (file ending | |
| 39 with .make), including "testwin", "testalpha", and "graywin". | |
| 40 | |
| 41 Copy the SDL library file into the test directory, and run! | |
| 42 | |
| 43 ============================================================================== | |
| 44 III. Building the Simple DirectMedia Layer demo programs: | |
| 45 | |
| 46 Copy one of the test program Makefiles to the demo directory | |
| 47 and modify it to match the sources in the demo. | |
| 48 | |
| 49 ============================================================================== | |
| 50 IV. Enjoy! :) | |
