[vorbis-dev] building under NetBSD and using /dev/audio

Thanks for the info. What Makefile? I added -lossaudio to the LDFLAGS and
LIBS lines in the src/plugins/oss/Makefile. 

It does change the make:
 /bin/sh ../../../libtool --mode=link gcc  -O20 -D__NO_MATH_INLINES
 -fsigned-char -DAO_PLUGIN_PATH=\"/usr/local/lib/ao\" -lossaudio -o
 liboss.la -rpath /usr/local/lib/ao -export-dynamic -avoid-version
 ao_oss.lo  -lossaudio

But it doesn't work (after I do a 'make install'):

 rainier:~/src/ogg/libao-0.6.0/src/plugins/oss$ /usr/local/bin/ogg123
 --verbose -d oss -o dsp:/dev/audio ~/audio/tmbg_older.ogg
 dlerror: (null)

 /usr/local/lib/ao/liboss.so: Undefined PLT symbol "_oss_ioctl" (reloc
 type = 7, symnum = 13)

If I try to build manually (no Makefile), I receive the following warning:

rainier:~/src/ogg/libao-0.6.0/src/plugins/oss$ /bin/sh ../../../libtool
--mode=link gcc  -O20 -D__NO_MATH_INLINES -fsigned-char
-DAO_PLUGIN_PATH=\"/usr/local/lib/ao\" -lossaudio -o liboss.la -rpath
/usr/local/lib/ao -export-dynamic -avoid-version ao_oss.lo  -lossaudio
rm -fr .libs/liboss.la .libs/liboss.* .libs/liboss.*

/usr/bin/ld -Bshareable  ao_oss.lo   -o .libs/liboss.so.0.0
(cd .libs && rm -f liboss.so.0 && ln -s liboss.so.0.0 liboss.so.0)
(cd .libs && rm -f liboss.so && ln -s liboss.so.0.0 liboss.so)
(cd .libs && rm -f liboss.so && ln -s liboss.so.0.0 liboss.so)
creating liboss.la
(cd .libs && rm -f liboss.la && ln -s ../liboss.la liboss.la)

I am not sure what this warning means exactly. Hopefully, I can figure out
how to link -lossaudio to the liboss.so.
