Gzserver: symbol lookup error After Launching bebop_without_controller.launch #39
Comments
Thanks for opening your first issue here! Make sure that no other issues on the same topic have already been opened! |
I deleted my catkin and made all steps again with no sucess. Do I need to install ros-melodic-rotors-gazebo and ros-melodic-rotors-gazebo-plugins like you stated on CrazyS installation ? |
Are you able to run the standard setup? If so, you do not need to install other packages. |
What do you mean by standard setup ? I just followed the steps on readme.txt and couldn't launch bebop_without_controller.launch. |
Okay, this means that something went wrong with it. Please, follow the instructions once more. |
I tried again and got the same error. |
This seems to be an old error. Please, see the issues mentioned above. |
I tried everything and it didn't work... |
Let use a systematic approach to solve the problem. Describe me every single step precisely. |
I solved my problem. I had to use catkin_make instead of catkin build. For this, I had to make some adjustments on package.xml and cmakelists.txt from rotors_simulator and then after building I was able to launch bebop_controller.launch with no errors. Thanks for your attention ! |
