Hi,
I have some trouble trying to compile the latest svn version of PCL.
I installed ROS latest from SVN in Ubuntu and then I was following the tutorial Downsampling a PointCloud using a VoxelGrid filter. After adding the required lines in the pcl/CMakeLists.txt file in order to compile the example src/examples/filter_voxel_grid.cpp and launching make I obtained the following linking error:
