There can be linking problems, they're not fundamental
incompatibilities - you just have to link to the right runtime, like
with any other libraries

ov_open doesn't take filenames. So I'm not sure what you were trying
to say. Try doing a debug build, so you can get some information about
where things went wrong.

I said (and demonstrated) that I pass the filename to fopen.  When fopen 
returns a null pointer, ov_open does not complain; when it returns a valid 
pointer, ov_open produces an exception.  I'm sure this is due to my own 
(painful) misunderstanding of how to get these ogg vorbis files correctly 
related to my project.  And that is probably why I can't get any debug info.
