Segmentation fault (core dumped) when running lsdc_slam node #17

Open cassini-fly opened 5 years ago

I followed the instruction for installation and compiling this package on ubuntu 16 and ROS Kinetic, it compiled successfully but upon running the slam node, I get segmentation fault. I am wondering what the problem can be.

Thanks!

I had this issue too. Had to use eigen in a specific way. Try following the instructions in my fork.

@MrMinemeet Thanks. I tried it on Melodic. It works fine. But on Kinetic, I get the following:
