Hello to everyone,

I have installed the last version of jderobot on Ubuntu 16.04 and I was
doing some test just to check that the installation is correct, but I've
got some errors.

These are the steps:

--1 Open a terminal and execute the following command:

* gazebo simpleCircuit.world  *

    it works fine, I could see the circuit and the racing car

--2  but then , after opening a second terminal  the following error shows

*cd /home/tfm3/TeachingRobotics/src/follow_line*
* python ./follow_line.py followLineF1.cfg*

Traceback (most recent call last):
  File "./follow_line.py", line 24, in <module>
    from gui.GUI import MainWindow
  File "/home/tfm3/TeachingRobotics/src/follow_line/gui/GUI.py", line 10,
in <module>
    from gui.widgets.cameraWidget import CameraWidget
  File "/home/tfm3/TeachingRobotics/src/follow_line/gui/widgets/cameraWidget.py",
line 3, in <module>
    import cv2
ImportError: libopencv_hdf.so.3.1: cannot open shared object file: No such
file or directory

Did I miss some steps during the installation ?  Did it happen to anyone
before ?

Thanks in advance
