compilation wrong

[pswpswpsw]

I used your cmake file: https://github.com/daviddoria/Examples/blob/master/c%2B%2B/PCL/Descriptors/PrincipalCurvaturesEstimation/CMakeLists.txt

and https://github.com/daviddoria/Examples/blob/master/c%2B%2B/PCL/Descriptors/PrincipalCurvaturesEstimation/PrincipalCurvaturesEstimation.cpp

It seems that I got error

Linking CXX executable PrincipalCurvaturesEstimation
/usr/bin/ld: CMakeFiles/PrincipalCurvaturesEstimation.dir/PrincipalCurvaturesEstimation.cpp.o: undefined reference to symbol '_ZN5boost6system15system_categoryEv'
//usr/lib/x86_64-linux-gnu/libboost_system.so.1.54.0: error adding symbols: DSO missing from command line
collect2: error: ld returned 1 exit status
make[2]: *** [PrincipalCurvaturesEstimation] Error 1
make[1]: *** [CMakeFiles/PrincipalCurvaturesEstimation.dir/all] Error 2

Do you know what is going on?

I figured it out, at least on my computer, CMakeLists.txt need to add two additional library at the end.

target_link_libraries(PrincipalCurvaturesEstimation
pcl_io
pcl_common
pcl_features
pcl_search
pcl_filters
pcl_kdtree
pcl_surface
pcl_keypoints
boost_thread
boost_system
)

Great, I'm glad you got it to work. Would you mind editing the page to reflect the required changes?
