The message
++ WARN: could not open input stream...
may mean that have to run this as root on OSX. If I recall correctly OSX
restricts access to the CD drive for certain kinds of access I think for
security reasons. And only one application can have "exclusive" access. So
if another device as access already to the CD drive then another program
won't be able to get access. So also check that nothing else is accessing
the drive.
The fact that you were able to compile libcdio and run that program means
that certain things do work. To get an idea of what works and what doesn't
work run the tests via "make check".
Finally OSX support on libcdio has been weak for several reasons. First
traditionally has been a kind of secrecy in how you control and get access
to the DVD device. Perhaps that's now fixed. I believe libcdio uses and
older Mach/BSD compatibility calls still.
The second problem at least from my standpoint has been that I don't own a
OSX box and have rarely had access to one for testing libcdio. So I can't
test it. But I think others in the project do and do test this pretty
regularly.
Finally, there is just a lack of people who want to work on those
lower-level aspects that the code needs for running cd-info and cd-drive.
So if you are interested in working on the driver, by all means do. If you
know of a way to give access to OSX boxes to developers for testing, by all
means let us known.
