SDL_Mixer and Ogg Vorbis support

SDL Development
1

Okay, I’ve downloaded all the ogg vorbis stuff from the ogg vorbis CVS,
compiled SDL (again) from the August 1st CVS snapshot and then tried to
compile SDL_Mixer with Ogg Vorbis support…

but

The first time I compiled it, it worked in the debug version but not the
release version.

So I nabbed the CVS version and it doesn’t compile in either versions then.

Linking…
Creating library Release/SDL_mixer.lib and object Release/SDL_mixer.exp
music_ogg.obj : error LNK2001: unresolved external symbol _SDL_Error
Release/SDL_mixer.dll : fatal error LNK1120: 1 unresolved externals
Error executing link.exe.

SDL_mixer.dll - 2 error(s), 0 warning(s)

And yes it’s linked against sdl.lib

including SDL_error.h doesn’t help.

in music_ogg.c there are two calls to “SDL_OutOfMemory()”
(line 80 and 136). you need to change these both to
"SDL_SetError(“Out of memory”)". once you do that you’ll
be up and running.

for some reason i thought i submitted this and it was fixed
in the latest SDL_mixer cvs code, but i guess not. Sam?

ah, i remember the problem now (moments after hitting the "send"
in my previous post). the function SDL_Error is not in the list
of exported functions for SDL. it needs to be added to the "SDL.def"
for SDL.

ahyes, i’ve built SDL_mixer with oggvorbis support, but
there is a problem in the source. the solution is pretty
simple…

if you still can’t get it built, the version i have is
available online.

Hello,

I got this same error to before. I think this might be a bug, I am not for
sure.

To fix:
1.Find the file music_ogg.c in SDL_mixer’s library
2.Change the line SDL_OutOfMemory(); to say SDL_SetError(“Out of memory”);
3.Compile and it should work just fine!

I am not sure what the problem is though, It compiles just fine on Linux with
OGG support without changing any files.
