Hello,

i try to start the erlecopter example in Gazebo from Erle Robotics for Q-Learning. But i faced some Problems and tried to spawn the Copter in the right Environment, first i start my conda Environment and after that i start roscore, then i open a new Terminal with the same conda Environment and source my catkin workspace, after that i put in the command:

roslaunch ardupilot_sitl_gazebo_plugin erlecopter_spawn.launch

Gazebo started correctly with the Quadcopter in it but the Terminal put out an Error:

[libprotobuf FATAL google/protobuf/stubs/common.cc:67] This program requires version 3.5.0 of the Protocol Buffer runtime library, but the installed version is 3.0.0.  Please update your library.

log file: /home/stephan/.ros/log/2845833a-69a3-11e9-9559-50e54953a336/gazebo-3*.log

Because the error message says "core dumped" and in the empty.world file the physics is set with ode, i suspect that something is wrong with my graphic-driver... again.

I'm also not sure why i got this libprotobuf FATAL message, i already updates it to 3.6.1 and can see this version with the command: conda list

I have to say that this example from Erle Robotics is out of date, its for Ubuntu 14.04 with ROS Indigo and i changed a few things to compile it, cause i work with Ubuntu 18.04 and ROS Melodic.

I dont want to spam this Thread unnecessary long, if u want more Informations or Logs please tell me.

I'm grateful for every tip.

Do you have a self compiled version of Gazebo or protobuf? I had this problems before because I ended up to have two versions of protobuf on my machine and gazebo was linking to the wrong one.

I guess i have the same issue, because my pip show output is:

it seems that i have 3.7.1 and 3.0.0 in different locations. I have to use conda for different Python environments and used this command as i firstly got the Error from the first post:

conda install -c anaconda libprotobuf

How did you fix the issue with the wrong direction, LD_LIBRARY_PATH?

Thank you!

I had this problem before and it was because I had two protobuf installation on my machine and Gazebo was being complied with the oldest.

In order to solve that, I installed Gazebo from source. Note that ign-msgs and ign-transport also requires protobuf and need to install them from source as well.

Changing LD_LIBRARY_PATH will most likely make the cmake to find the correct protobuf version.

And if i change something in my catkin workspace folder (especially in the CMakeLists.txt where protobuf directory is mentioned) i have to rebuild it with catkin_make Thats it, right?
