Description Göran Uddeborg 2002-03-25 20:56:47 UTC 
As documented by the file libSDL_mixer.la, one needs to link with all of
libvorbisfile, libvorbis, and libogg when using libSDL_mixer.  That also mean it
would make sense to let SDL_mixer-devel require libvorbis and libogg, doesn't
it?  (Or am I missing some way the package could be used without these other
libraries also installed?)

Since SDL_mixer itself is linked against libvorbis, libvorbisfile and libogg, 
there's no need to link applications using it against those libraries: That is 
done implicitely. So yes, you can build stuff using SDL_mixer even if you 
don't have the ogg and vorbis development environments installed. 
 
libtool (cause of the *.la files) is designed mostly with crappy systems in 
mind that don't allow shared libraries to depend implicitely on others, that's 
why libtool insists putting in -lvorbis and friends even though it's not 
necessary.
Comment 2 Göran Uddeborg 2002-07-06 19:25:41 UTC 
That's interesting.  You learn all the time.

But then it would instead need libogg and libvorbis, wouldn't it?  If I remove
for example libvorbis.so.0 (from libvorbis, not libvorbis-devel), I don't seem
to be able to link any more.

You could in principle do a separate compilation,
without linking, using only the header file SDL_mixer.h.  So very strictly you
could use the package without the libvorbis package.  But for any meaningful
case it seems at least libvorbis and libogg would be needed.

I lowered the seveity of this bug.  It is fine tuning.  I leave it to you to
decide if it is too much fine tuning to bother with at all, or if it is worth it.
Comment 3 Göran Uddeborg 2004-09-24 06:39:00 UTC 
I took another look at this.  Now SDL_mixer-devel requires (a
particular version of) SDL_mixer, and SDL_mixer requires the libraries
from libvorbis.  So it seems all needed requirements are there today.
 I'll close this.
