I want to run sample code from PCL site to simple read cloud from file. I installed libraries, and prepared build script:

g++ -std=c++11 main.cpp -lboost_system `pkg-config --libs --cflags opencv4` -g -o main

but compiller throws many errors like:

/usr/include/pcl/io/pcd_io.h:56: undefined reference to `vtable for pcl::PCDReader'

I know that I need to linking libpcl_io.so like I linked boost library by adding -lboost_system , but my question is - how? I tried add to script something like -lpcl, -libpcl, -lpcl_io, but it doesn't works

So, what is keyword to linking PCL Libraries?

Are you making use of CMake and Make? – Eric Bringley Aug 19 '19 at 09:30
No, just save this script as .sh, make it executable and run, when I want to build my program. I always did it this way – Fidor Aug 19 '19 at 09:57

Do you have any good reason not to use CMake? Exactly because of this reason, CMake is being used, so you don't have to worry about all of the `g++` shenanigans. – serkan.tuerker Aug 19 '19 at 18:28
How did you install PCL? – Florian Weimer Sep 01 '19 at 18:15
