1) When trying to run "image_view" (with all kind of images...tried
different Image topics), I get this:
$ rosrun image_view image_view image:=/camera/rgb/image_color
[rospack] warning: ignoring duplicate "nodelet" tag in export block
opengl support available
(<unknown>:15605): GLib-GObject-WARNING **: invalid uninstantiatable type
`(null)' in cast to `GtkWidget'
(<unknown>:15605): GLib-GObject-WARNING **: instance of invalid
non-instantiatable type `(null)'
(<unknown>:15605): GLib-GObject-CRITICAL **: g_signal_connect_data:
assertion `G_TYPE_CHECK_INSTANCE (instance)' failed
2) With "camera_calibration", I get errors as following:
$ rosrun camera_calibration cameracalibrator.py BLABLABLAH
Traceback (most recent call last):
line 50, in <module>
ImportError: /usr/local/lib/python2.7/dist-packages/cv2.so: undefined
What results did you expect? What did you get?
None of these problems occur when I use (switch back) to diamondback. The
packages work as expected in diamondback. I have tried both binary and
from-source packages with the same results.
I hope this could give you an idea of the problem.
Thanks a lot for looking into it!
