Hi, guys!
Maybe I have met the same issue when I tried to compile ROS nodes file ./build_ros.sh in /isee-camvox folder. I have got PCL-1.8 version, but it was permanently working with other Livox repositories needed PCL-1.7. Anyway I installed PCL-1.7 and boost-1.58, but the problem haven't been solved.

This is an error message:

Feeling so sorry for the slow rely. I think Compilation errors occur, most of which are caused by PCL library problems ,we have update the PCL library install method and supply the installation package link, you can try it.
