Hi, I faced the same issue sometimes, and using catkin_make_isolated instead of catkin_make always fixed the issue.

@Piroro-hs It's worked for me too, thx~

Hello, I have a similar bug, here are the steps I ran

sudo apt-get update
sudo apt-get install ros-kinetic-rplidar-ros
roslaunch rplidar_ros rplidar_a3.launch

Here is the results:

I've tried compiling from source, and it works, this indicates that the Debian packages are not updated. My system is Intel NUC running Ubuntu 16.04

Thank you @kintzhao

I'm getting the same crash, both with the apt-installed package, and also with my compiled one in a vendor catkin workspace.

I finally solved it by building using catkin_make_isolated, many thanks @Piroro-hs.

$ apt show ros-kinetic-rplidar-ros
Package: ros-kinetic-rplidar-ros
Version: 1.7.0-0xenial-20180824-112159-0800

and then when running:

$ roslaunch rplidar_ros rplidar_a3.launch

https://github.com/robopeak/rplidar_ros/pull/82 [param]add param angle_compensate_multiple Default angle_compensate_multiple(Running at 10HZ): 16K -- 4 8K -- 2 4K -- 1 angle_compensate_multiple is min(setting value, default value)

[Zacrain]

Thank you @neomanic and @Piroro-hs ! Fixed it for me. Installing the package via apt led to the same problem. Compiling it from source using catkin_make_isolated fixed it.

I'm running ROS Kinetic under Ubuntu 16.04.

#82 [param]add param angle_compensate_multiple Default angle_compensate_multiple(Running at 10HZ): 16K -- 4 8K -- 2 4K -- 1 angle_compensate_multiple is min(setting value, default value)

Thank you very much! Using your patch finally makes it work on Ubuntu 18.04 with kinetic!
