Updating to PCL 1.7 in ROS Fuerte

edit

a patch has been pushed in a recent version of ROS pcl 1.7 package. So the above method should work for anyone trying to install pcl 1.7, I have finally been able to get the correspondence tutorial to work! :u)

I try you're version and come back if it works. The other suggestions did not work for me. So compiling from source and installing that one. (The ones mentioned under this post. Also the documentation is a bit less in case an error happens)

I could compile the package but I could not yet link it to another project. Maybe some suggestions? In the cmake file everything works fine.

Linking the libraries: target_link_libraries(minitof_listener pcl17_features pcl17_io pcl17_2d pcl17_people pcl17_kdtree pcl17_registration pcl17_recognition pcl17_tracking pcl17_stereo pcl17_filters pcl17_common pcl17_visualization pcl17_octree pcl17_sample_consensus ... etc. )

@ncr7 run rosmake on pcl17 is taking for ever more than 3000 s is this normal?? how long should it take?

Yes, it takes awhile to build.

It depends on your configuration and your computer. 50 minutes can be ok. A typical mistake is to use too many job if you don't have enough memory and the swap muss be used.

@MichaelKorn@ncr7 After a while it took 4 hr but it got the job done thanks, the thing is that i only did rosmake on pcl17 and not on pcl17_ros, whats the difference between this two? because right now i can use programs from pcl17 with no problems

pcl17 is just the pcl, no ROS code! pcl17_ros contain ros code, based on the pcl.

@MichaelKorn@ncr7 im having a little problem trying to use some code of the pcl17, specifically the detection of people, with ROS. Right now i need to publish the distance i get from getDistance() but im unable to accomplish it. Do you have any idea how to do it or experience working this package with ROS?

I have used pcl17, but haven't tried detection of people yet. Sounds like an interesting thing to get working though, if I get time I'll try testing it. CarolineQ might have some answers though, http://answers.ros.org/question/61607/pcl-people-detector-problem/

@MichaelKorn@ncr7 as i said im working on pcl17 and specifically on main_ground_based_people_detection.cpp , the thing is i dont know how to compile the new code or changes to the code without doing rosmake to everything, is the a way to compile the changes without doing the whole rosmake

the make system should check the timestamp of all involved files, but compile only changed files (recursively).

@MichaelKorn thanks i did it and it did not take as long, but when i change the main_ground_based_people_detection.cpp and run the rosmake the exe is not changed? do you know why?

pcl17 is not foreseen to make changes of the source code. But it should work if you remove the file "installed" before make.

@MichaelKorn thanks it worked, but now as i expected it said there was a failure, but nothing more so i cant see which is the problem in the code , any ideas?

maybe make it directly: roscd pcl17 && cd build/pcl_trunk/build && make

@MichaelKorn@ncr7 ok thanks, the error i get is "undefined reference to `ros::init" even though i included ros/ros.h , any ideas why?

might be a linking issue, try adding these lines to your cmake. include_directories(/usr/include/vtk-5.8) target_link_libraries(<your_executable_node> ${PCL_LIBRARIES} boost_system libvtkCommon.so libvtkFiltering.so libvtkRendering.so) Also, maybe check your depends packages in your manifest.xml.
