Hi Josh,

I was wondering if you could lend a hand. I'm getting the following error when attempting to run any of the examples:

/usr/lib/ruby/1.8/ffi/library.rb:113:in `attach_function': Function 'freenect_sync_get_video' not found in libfreenect.so, libfreenect_sync.so

from record.rb:18

Thanks to Miguel for the heads up!

This is most likely because an older version of the libfreenect library is included with the linux package in use. We have made the 'sync' library bindings conditional upon availability. A warning will be issued if an older version of the library is installed, but the core library bindings should still work.

Fix appears to have solved the issue. Will confirm tonight when I get my hands on my Kinect.

Can you confirm this worked? I'd like to close the issue.

cheers

The guy who reported it said he was still having problems. I'm going to see if I can't troubleshoot this tonight.
