Thanks for the answer Radu. I will modify the wiki pages... I realized later that the tutorials were already included in src/examples :)

Regards

Jordi

Dear Jordi,

Thanks for the heads up. You're right, since the tutorial got created, the structure of the library modified a bit, and pcl_filters is now needed. Can you please modify the tutorial wiki pages to reflect these changes?

PS. The tutorials are already existing in pcl/src/samples in case you don't want to copy & paste the code again ;)

Cheers,
Radu.

In fact there was a mistake in the tutorial. There is actually a missing
dependency:

target_link_libraries (tutorial_filter_voxel_grid pcl_io *pcl_filters*)

   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.
   <http://www.ros.org/wiki/pcl/Tutorials/Downsampling%20a%20PointCloud%20using%20a%20VoxelGrid%20filter>

   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:

   Is there any dependency missing?
