Segfault in PCL conversion (ROS Noetic) #16

Open mangtronix opened 3 years ago

mangtronix commented 3 years ago

When I run the publisher it segfaults. Sometimes I get a frame of data that shows in rviz. GDB output is below.

I'm using ROS Noetic, Ubuntu 20.04.2, libpcl-dev 1.10.0

What version of ROS does the example work with? It looks like there was a change in the Point Cloud Library for ROS Noetic.

https://varhowto.com/ros-noetic/ The point cloud library is PCL 1.10 in Noetic, compared to 1.8 in Melodic.

Hello magtronix. Sorry for the late reply. We are testing on Noetic. Please wait a little more. Thank you.
