Make sure you have every lib sdl_sound needs compiled and installed as well. In this case it looks like smpeg is missing perhaps.
I never succeeded with SDL_sound on Windows (but that was four years ago) while it isn't that hard on OS X...

SDL_Sound needs a ton of external codecs you need to compile, so select what you want and discard what you don't, you need to satisfy dependencies or turn decoders off. I only use ogg and all three libraries (not incluiding SDL itself) compile just fine under Windows.

Could you show me how do I turn decoders off? Just like you, I'd like to have ogg installed as my personal preference
I thought there were #define's to exclude or exclude libs out.
Let me know
Thanks
Jack

If you use mingw you can do stuff like that through configure switches.
In msys cd to the folder with SDL_sound and run
./configure --help
Now you'll see available options. Configure will recognize which libs are installed on its own normally, though.

If you use visual c you will need to find other ways. I never used that

I wonder if you use command-line mode to build dosbox, when you want to step thru the code to
understand how things work,
how do you do that?
Thanks
Jack

Hello,
Although I didn't want to have the rest of the codecs, strange enough, I am able to compile SDL_Sound by luck.
However, when I link it with VS2010,
I got the following error

1Error	3	error LNK1104: cannot open file 'LIBC.lib'	E:\Jacky\Downloads\dosbox\sdl_sound_visualc_srcs\SDL_sound\visualc\LINK	sdl_sound_dll

I found that the project was pointing to the smpeg.h at ..\..\smpeg\smpeg
now I add one line before it, E:\Jacky\Downloads\dosbox\sdl_sound_visualc_srcs\SDL_sound;
Then it is able to be compiled, not linked.
Thanks
Jack

It seems to be errors and looking for the right libvorbis.lib

Thanks
Jack

Those are linker errors, compile your own libvorbis and your own libogg.

I'm starting to wonder if you're just trolling.
