So I have spent pretty much all day going through the code trying to
understand whats going on to find the problem.
It seems that on start up the seperate devices should have files created for
them in /tmp/gazebo-USER-0/, but the only one that gets created is
simulation and a few graphics references. I think it is
gazebo/trunk/player/GazeboDriver.cc that creates an instance of each device
based on what is defined in gazebo.cfg. I have tried printing debug
statements to check that the devices are read in, and it seems that they are
and are understood by gazebo. Commenting out the initialisation within the
big switch case statement, causes the start up to fail because the device
cannot be created. So obviously it thinks that it is creating these files
correctly, but I cannot seem to identify why the files are not created.
Can anyone with more knowledge of the code point me towards where in the
code I can check this process?
Thanks
