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: [100%] Linking CXX executable ../camvox /usr/bin/ld: warning: libboost_system.so.1.65.1, needed by /opt/ros/melodic/lib/libroscpp.so, may conflict with libboost_system.so.1.58.0 /usr/bin/ld: warning: libboost_filesystem.so.1.65.1, needed by /opt/ros/melodic/lib/libroscpp.so, may conflict with libboost_filesystem.so.1.58.0 /usr/bin/ld: warning: libboost_thread.so.1.58.0, needed by ../../../lib/libCamvox.so, not found (try using -rpath or -rpath-link) /usr/bin/ld: warning: libpcl_common.so.1.7, needed by ../../../lib/libCamvox.so, not found (try using -rpath or -rpath-link) /usr/bin/ld: warning: libpcl_kdtree.so.1.7, needed by ../../../lib/libCamvox.so, not found (try using -rpath or -rpath-link) /usr/bin/ld: warning: libpcl_search.so.1.7, needed by ../../../lib/libCamvox.so, not found (try using -rpath or -rpath-link) /usr/bin/ld: warning: libpcl_filters.so.1.7, needed by ../../../lib/libCamvox.so, not found (try using -rpath or -rpath-link) /usr/bin/ld: warning: libpcl_io.so.1.7, needed by ../../../lib/libCamvox.so, not found (try using -rpath or -rpath-link) /usr/bin/ld: warning: libpcl_visualization.so.1.7, needed by ../../../lib/libCamvox.so, not found (try using -rpath or -rpath-link) /usr/bin/ld: warning: libpcl_segmentation.so.1.7, needed by ../../../lib/libCamvox.so, not found (try using -rpath or -rpath-link) /usr/bin/ld: warning: libvtkRenderingFreeTypeFontConfig-6.2.so.6.2, needed by ../../../lib/libCamvox.so, not found (try using -rpath or -rpath-link) /usr/bin/ld: warning: libvtkRenderingMatplotlib-6.2.so.6.2, needed by ../../../lib/libCamvox.so, not found (try using -rpath or -rpath-link) /usr/bin/ld: warning: libvtkRenderingFreeTypeOpenGL-6.2.so.6.2, needed by ../../../lib/libCamvox.so, not found (try using -rpath or -rpath-link) /usr/bin/ld: warning: libGLEW.so.1.13, needed by ../../../lib/libCamvox.so, not found (try using -rpath or -rpath-link) /usr/bin/ld: warning: libvtkInteractionStyle-6.2.so.6.2, needed by ../../../lib/libCamvox.so, not found (try using -rpath or -rpath-link) /usr/bin/ld: warning: libvtkRenderingFreeType-6.2.so.6.2, needed by ../../../lib/libCamvox.so, not found (try using -rpath or -rpath-link) /usr/bin/ld: warning: libvtkRenderingOpenGL-6.2.so.6.2, needed by ../../../lib/libCamvox.so, not found (try using -rpath or -rpath-link) /usr/bin/ld: warning: libvtkRenderingCore-6.2.so.6.2, needed by ../../../lib/libCamvox.so, not found (try using -rpath or -rpath-link) /usr/bin/ld: warning: libvtkCommonDataModel-6.2.so.6.2, needed by ../../../lib/libCamvox.so, not found (try using -rpath or -rpath-link) /usr/bin/ld: warning: libvtkCommonMath-6.2.so.6.2, needed by ../../../lib/libCamvox.so, not found (try using -rpath or -rpath-link) /usr/bin/ld: warning: libvtkCommonCore-6.2.so.6.2, needed by ../../../lib/libCamvox.so, not found (try using -rpath or -rpath-link) ../../../lib/libCamvox.so: undefined reference to pcl::search::Search<pcl::PointXYZ>::getName() const' ../../../lib/libCamvox.so: undefined reference toboost::this_thread::hiden::sleep_until(timespec const&)' ../../../lib/libCamvox.so: undefined reference to vtkRenderingFreeTypeOpenGL_AutoInit_Destruct()' ../../../lib/libCamvox.so: undefined reference tovtkRenderingFreeTypeOpenGL_AutoInit_Construct()' collect2: error: ld returned 1 exit status CMakeFiles/camvox.dir/build.make:462: recipe for target '../camvox' failed make[2]: [../camvox] Error 1 CMakeFiles/Makefile2:343: recipe for target 'CMakeFiles/camvox.dir/all' failed make[1]: [CMakeFiles/camvox.dir/all] Error 2 Makefile:129: recipe for target 'all' failed make: *** [all] Error 2

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.
