Spawning Error
Closed this issue · 5 comments
Hello,
I keep getting an error whenever I try to run that launch command right after I install the package:
roslaunch bebop_simulator bebop_without_controller.launch
What I get:
[rospack] Warning: error while crawling /home/ami/catkin_ws/src/BebopS: boost::filesystem::status: Too many levels of symbolic links: "/home/ami/catkin_ws/src/BebopS/BebopS"

I'm relatively new to ROS but I wanted to use this package to implement my control system on a drone for a school project. Any help would be greatly appreciated.
Thanks in advance.
Did you follow the instructions in the README file? There seems to be some problem with the bashrc file.
First of all, thanks for your reply. To answer your question, yes I have followed all of the steps. What would you recommend to do in order to fix the problem with the bashrc file?
Update: I have removed then re-installed Ubuntu 16.04 on a virtual machine. Then I re-installed ROS and Gazebo 7, followed all the steps again, and was able to launch the simulation without any errors this time. I can work on designing/implementing my controller now. Thank you so much for providing such a beneficial package for simulation and testing purposes.
Hello, just wanted to inform that I also had a problem identical to this one, and was able to solve it by removing the link Bebop inside this repository (catkin_ws/src/BebopS/BebopS).
Haven't tested with with all the launch files, but bebop_without_controller.launch and multiple_bebop_without_controller.launch, seem to work, while previously the UAVs did not spawn.
