I am building a managed assembly in Visual Studio.Net 2003 that can encode and decode ogg vorbis files. I currently have it decoding files fine, however when I link in vorbisenc.lib I get a bunch of errors saying that certain symbols are already defined in vorbis.lib.
How do I link in the libraries

vorbisenc.lib
vorbis.lib
ogg.lib

without the symbols in vorbisenc.lib conflicting with vorbis.lib?

Thanks very much!
