Problems building & running Openni2_camera

edit

Hi All,

I've managed to download and successfully compile OpenNi2 and run the sample apps.

Getting some problems with Openni2_camera however:

Compiling I get the likes of:

/home/mark/catkin_ws/devel/lib/libopenni2_wrapper.so: undefined reference to `oniStreamRegisterNewFrameCallback'
/home/mark/catkin_ws/devel/lib/libopenni2_wrapper.so: undefined reference to `oniStreamGetProperty'
/home/mark/catkin_ws/devel/lib/libopenni2_wrapper.so: undefined reference to `oniDeviceIsCommandSupported'
/home/mark/catkin_ws/devel/lib/libopenni2_wrapper.so: undefined reference to `oniDeviceSetProperty'
/home/mark/catkin_ws/devel/lib/libopenni2_wrapper.so: undefined reference to `oniReleaseDeviceList'
/home/mark/catkin_ws/devel/lib/libopenni2_wrapper.so: undefined reference to `oniStreamDestroy'
/home/mark/catkin_ws/devel/lib/libopenni2_wrapper.so: undefined reference to `oniStreamStart'
/home/mark/catkin_ws/devel/lib/libopenni2_wrapper.so: undefined reference to `oniDeviceCreateStream'

And probably related:

Running (or trying to)

rosrun openni2_camera OpenNI2.cfg

I get

Traceback (most recent call last):
File "/home/mark/catkin_ws/src/openni2_camera/cfg/OpenNI2.cfg", line 7, in <module>
  gen = ParameterGenerator()
 File "/opt/ros/groovy/lib/python2.7/dist-packages/dynamic_reconfigure/parameter_generator_catkin.py", line 234, in     __init__
self.dynconfpath = sys.argv[1]  # FIXME this is awful
IndexError: list index out of range

I'm running this with Groovy on my PC. Was to stick with Groovy ideally as I'm going to migrate it all to my Raspberry Pi

Many Thanks

Mark
