I am trying to follow the ROS tutorial titled: "How to Calibrate a Monocular Camera", link I am using the gscam driver and have verified that it is publishing correctly. Also steps 1.1-1.3 executed without error, but at step 1.4 when I enter:

rosrun camera_calibration cameracalibrator.py --size 8x6 --square 0.108 image:=/camera/image_raw camera:=/camera

I get:

('Waiting for service', '/camera/set_camera_info', '...')
Service not found

(display:17709): GLib-GObject-WARNING **: cannot register existing fundamental type 'gchar' (as 'gchar')
**
GLib-GObject:ERROR:/build/buildd/glib2.0-2.40.0/./gobject/gvaluetypes.c:455:_g_value_types_init: assertion failed: (type == G_TYPE_CHAR)
Aborted (core dumped)

If I run it with the "--no-service-check" option, I get:

Exception in thread Thread-4:

If it helps below is the output of "rostopic list"

Any help would be appreciated, I'm running this on Indigo, Ubuntu 14.04

Edit: Output from "rosservice list"

This error is due to the fact that ROS cannot find the package. By default ROS will search inside "stack" or "share" depending on the version of ROS, for the package. Once you completed Step 5, the "eddiebot" folder was probably placed in: "/home/christopher/eddiebot"

You need to move it into: "opt/ros/fuerte/share/"

This can be done by the following:

sudo mv -i eddiebot opt/ros/fuerte/share
