Date: 10 Jun 2003 15:30:59 -0400 From: Mike Shal Subject: [SDL] Bug in SDL_wave.c? Hey everyone, I'm not sure if this is a bug in SDL, or if I just have incorrect WAV files. The problem I'm having is loading multiple concatenated WAVs from SDL_LoadWAV_RW. Some WAV files put comments at the end of the file (which may be bad form), and SDL doesn't skip past them when reading from the RWops. So the next WAV I try to load will start at the comment section of the previous WAV, which obviously doesn't work. If anyone else is having this problem, one quick fix you can do is run sox on the bad WAVs, which strips out all of the comment sections. Eg: $ sox sound.wav tmp.wav $ mv -f tmp.wav sound.wav The other fix is to patch SDL_wave.c, which is included with this email. (Assuming I made the patch correctly :). All it does is calculate how much remaining space there is in the WAV file after the data chunk, and does SDL_RWseek to skip it. I don't think it should interfere with anything else, but if someone could check it that would be nice :). If the bug is really with SDL and not with my WAVs, can someone work this into the next version of SDL? Thanks, -Mike Shal

==============================================================================
Using the Simple DirectMedia Layer with MacOS 7,8,9 on PPC
==============================================================================

These instructions are for people using the Apple MPW environment:
http://developer.apple.com/tools/mpw-tools/

CodeWarrior projects are available in the CWprojects directory.

==============================================================================
I.  Building the Simple DirectMedia Layer libraries:
    (This step isn't necessary if you have the SDL binary distribution)

  First, unpack the MPWmake.sea.hqx archive and move SDL.make into the
  SDL directory.

  Start MPW

  Set the current directory within MPW to the SDL toplevel directory.

  Build "SDL"  (Type Command-B and enter "SDL" in the dialog)

  If everything compiles successfully, you now have the PPC libraries
  "SDL" and "SDLmain.o" in the 'lib' subdirectory.

==============================================================================
II. Building the Simple DirectMedia Layer test programs:

  First, unpack the MPWmake.sea.hqx archive, move the new rsrc directory to
  the main SDL directory, and move the makefiles in the new test subdirectory
  to the SDL 'test' subdirectory.

  Start MPW

  Set the current directory within MPW to the SDL 'test' subdirectory.

  Build the programs that have an associated MPW makefile (file ending
  with .make), including "testwin", "testalpha", and "graywin".

  Copy the SDL library file into the test directory, and run!

==============================================================================
III. Building the Simple DirectMedia Layer demo programs:

  Copy one of the test program Makefiles to the demo directory
  and modify it to match the sources in the demo.

==============================================================================
IV.  Enjoy! :)

  If you have a project you'd like me to know about, or want to ask questions,
  go ahead and join the SDL developer's mailing list by sending e-mail to:

	sdl-request@libsdl.org

  and put "subscribe" into the subject of the message. Or alternatively you
  can use the web interface:
