Trouble with launching driver #188

Open WiPhi7600 opened 5 years ago

WiPhi7600 commented 5 years ago

I know there is a similar post about this made a while ago, but considering there isn't a really detailed answer on how to solve this, I thought I might post this to try and get a more in depth solution.

I tried using the instructions here https://bebop-autonomy.readthedocs.io/en/latest/running.html and the preceding instructions. But I keep getting the following error:

will@will-VirtualBox:~/bebop_ws/devel$ roslaunch bebop_driver bebop_node.launch... logging to /home/will/.ros/log/a5e7ba98-47b0-11e9-a5e9-080027ad78cc/roslaunch-will-VirtualBox-17640.log Checking log directory for disk usage. This may take awhile. Press Ctrl-C to interrupt Done checking log file disk usage. Usage is <1GB.

I tried changing the LD_LIBRARY_PATH but have had no success. If anyone could help, it would be much appreciated thank you!

Are you using a Virtual Box to run the bebop_autonomy package? It may be the issue.

WiPhi7600 commented 5 years ago

I am, I use a Mac and though I've seen tutorials successfully using a VM to run autonomy, I haven't seen them do it for ubuntu 18.04 and melodic

I am getting a similar error:

I am currently running roscore and Bebop 2 on Sphinx in the same PC as well (although the WiFi hotspot doesn't seem to get along with my hw). I am using Xubuntu 18.04 and ROS melodic.

I think this is a duplicate of #170

For fixing your LD_LIBRARY_PATH, you have to check the path of libarcommands.so

$ locate libarcommands.so

In my case, this returns

/opt/ros/melodic/lib/parrot_arsdk/libarcommands.so

And then set LD_LIBRARY_PATH accordindly :

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opt/ros/melodic/lib/parrot_arsdk/

temporarily for testing and then permanently in your bashrc , or zshrc , or etc..
