An error occurred while I was running 2D demo about cartographer_ros HOT 13 CLOSED

You need to run the source install_isolated/setup.bash command in every terminal that you want to use cartographer in. This could be documented better.

Sounds like you didn't build everything first?

I am completely in accordance with the latest version of the tutorial.

Thank you,it was my mistake，i have run the
echo "source ~/install_isolated/setup.bash" >> ~/.bashrc
source ~/.bashrc

But,when i was running 2d demo bag, I get another erro：
[cartographer-3] process has died [pid 4946, exit code -6, cmd /home/robot/catkin_ws/install_isolated/lib/cartographer_ros/cartographer_node -configuration_directory /home/robot/catkin_ws/install_isolated/share/cartographer_ros/configuration_files -configuration_basename backpack_2d.lua echoes:=horizontal_laser_2d __name:=cartographer __log:=/home/robot/.ros/log/002a0b9e-718c-11e6-a06c-000c29e30f9c/cartographer-3.log].

@rohbotics ，hi，I get another erro：

Sounds like an alignment issue. Are you running on a 32-bit system? I'm asking because it should not be an issue on 64-bit systems. If you're not: processor? OS? compiler?

from cartographer_ros.

@carl1218 I'm closing this issue now since it seems clear that this is an alignment issue from running on 32-bit. This incompatibility is now documented in our system requirements.

from cartographer_ros.

I was running 2D demo bag and got this issue:

• ERROR: cannot launch node of type [robot_state_publisher/robot_state_publisher]: robot_state_publisher
  ROS path [0]=/opt/ros/indigo/share/ros

from cartographer_ros.

This doesn't seem Cartographer related: See http://answers.ros.org/questions/
That said: Did you follow our installation instructions? Is ros-indigo-robot-state-publisher installed on your system? Did you source /opt/ros/indigo/setup.bash?

from cartographer_ros.

hello, when I run 2d-demo on my computer,found following errors. Can you me tell me why? thanks.

@herogan2017 Have you solved the problem? I just got the same problem, but I have already sourced the setup.bash.

from cartographer_ros.

I had the same error message as @herogan2017, and this thread was the top hit on Google. In my case, I had built only the cartographer_ros package, neglecting to build the cartographer_rviz package. After building cartographer_rviz and sourcing the proper setup.bash, it worked fine.

from cartographer_ros.

@herogan2017 I met this question just now. It needs run command "sudo apt-get install ros-kinetic-cartographer_rviz" to use rviz in this process. and now it works fine. By the way, the cartographer package can be install directly now.
