Vorbis - Mar 2001 - Followup to compiling Ogg on NetBSD-1.5/i386

Hi Jeremy,

I went through the list archives, and have been trying to follow and
implement things as I understand:

1. libao needs <sys/soundcard.h> and <machine/soundcard.h>, and so I
linked /usr/include/soundcard.h there.  

2. Since `soundcard.h' doesn't have SNDCTL_DSP_GETODELAY, I uncommented
that particular line in `src/plugins/oss/ao_oss.c'.  These steps made sure
that I had liboss files created in /usr/pkg/lib/ao/.

3. After that, I went to vorbis-tools. (**I had compiled libogg and
libvorbis earlier -- do I need to compile them again now that I have
made changes in libao ?**  I think not, but I still ask).

3. The rest of the stuff in your notes didn't make any sense to me (I'm
only a beginner user), but I gathered that we need to do something with
the -lossaudio option.  And I gathered that it has to be put in
ogg123/Makefile (ie, LIBS = -lossaudio *and* LDFLAGS = -lossaudio).  
Well, I ran `configure' first, then made the above changes, and `make
&&
make install' ...

... but still ogg123 reports "No such device oss". :-(

Now I'm back to a dead-end with no clue whatsoever.  Where have I gone
wrong/screwed up ... ?

Regards.

I've been looking for a way to id my ogg files as I encode them without
having to type everything in myself, and I came up with this solution:

cdex (it's for windows) will output wav files with id3 tags.

If oggdrop and/or oggenc could read the id3 tags off of the source wav file
and automatically put them in the ogg info, that would be very handy.

What do you think?

No you shouldn't have to.

My notes are not too good :)

I think I fixed this by using DL_LAZY instead of RTLD_NOW. This is in
libao-0.6.0-modified/src/audio_out.c.

Then if the libossaudio was missing, you'd get an error like:
"/usr/local/lib/ao/liboss.so: Undefined PLT symbol "_oss_ioctl"
(reloc
type = 7, symnum = 13)"

(I hope I remembered this correctly.)
