Compiling PCL 1.7 on Ubuntu 16.04 , errors in CMake generated Makefile

Question

I\'m trying to get PCL 1.7 (The point cloud library, not the other pcl) working on Ubuntu 16.04. I eventually hope to use for C++ stuff, but right now I\'m just trying to get th

This bug is still in 16.04, but there is a workaround.

1. sudo apt install libproj-dev

2. add the following line to your CMakeLists.txt file:
   list(REMOVE_ITEM PCL_LIBRARIES "vtkproj4")

The first provides the necessary libproj.so, and the second fixes errors when linking against a nonexistent (and unnecessary) libvtkproj4.

The other errors about referenced files not existing appear to be harmless (or at least my project compiles despite having the same errors).

Answer 3

There seems to be an issue with the installation with vtk6

described here : https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=819741

quick and dirty fix: make a symbolic link libproj.so in the requested directory:

sudo ln -s  /usr/lib/x86_64-linux-gnu/libproj.so.<your-version> /usr/lib/x86_64-linux-gnu/libproj.so
