[ros-users] Request for Clue: OSX-specific linker flags, dependency resolution

[Nicholas Butko]

So, the attached patch works for me (no runtime loading errors).

BUT

This is something I have been meaning to ask Jack about, because it has been
interfering with my use of OpenCV. When I try to use libdc1394 as a camera
module, I get errors from my firewire iSight camera. This is the only
firewire camera I currently have access to, so I don't know if it's a
general problem. As a consequence, I have had to specifically compile OpenCV
*without* libdc1394 support.

So, my question for Jack is, do you know what would cause the following
errors (this time from camera1394_node, but the same errors from OpenCV),
and can they be easily fixed?:
