I'm facing the same situation with the KdTreeANN error. I could get rid off the problem by modifying the pertaining lines to use KdTreeFLANN, and that solves that part. However, I still get errors related to vslam/frame_common/include/frame_common/frame_extended.h:194: error: ‘getPointsInBox’ was not declared in this scope I guess I'm going to just try the stable ros-cturtle-vslam from the repository for now.
