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

[Nicholas Butko]

Strangely, when I ran it just down, I actually got the prompt for a
password.

On a different note, rosdep install seems to be suppressing output from
macports, which is somewhat disconcerting to me. I like to be notified when
things are being installed on my computer, just so I can ctrl+c if I have
any objections =P

{{{
geometry rubinet$ rosdep install camera1394
executing this script:
 set -o errexit
#Packages
sudo port install libdc1394
# No rule for glut

Password:
geometry rubinet$
}}}
