With Unbuntu 14.04 and Indigo, I cloned the pointgreycameradriver to catkinws/src and did catkin_make install. When I:

roslaunch pointgrey_camera_driver camera.launch

if I

rostopic echo /camera/image_color

the cameranodeletmanager process dies. I don't know where the problem might be. This did work at one time. Also FlyCapture works.
