Can not use visp properly

[zychaoqun]

Hello,

I want to use the instrument visp to track the object,however,I encountered some problems which make me crazy. 1) I just download the by Source: git https://github.com/lagadic/vision_visp.git (branch: hydro) in opt/ros/hydro/share. Then I try to launch the file in visp_tracker/tutorial.launch, however,there are always some problems like: ERROR: cannot launch node of type [visp_tracker/tracker]: can't locate node [tracker] in package [visp_tracker] ERROR: cannot launch node of type [visp_tracker/visp_tracker_client]: can't locate node [visp_tracker_client] in package [visp_tracker] ERROR: cannot launch node of type [visp_tracker/visp_tracker_viewer]: can't locate node [visp_tracker_viewer] in package [visp_tracker]

Even I uninstall the linux and Ros ,it is all the same. 2.I try to install the visp from source, when I try to catkin_make the visp_auto_tracker in my catkin_ws,there is also problems like: In file included from /home/chaoqun/catkin_ws/src/vision_visp/visp_auto_tracker/flashcode_mbt/detectors/qrcode/detector.cpp:1:0: /home/chaoqun/catkin_ws/src/vision_visp/visp_auto_tracker/flashcode_mbt/detectors/qrcode/detector.h:9:18: fatal error: zbar.h: No such file or directory compilation terminated. make[2]: * [vision_visp/visp_auto_tracker/CMakeFiles/visp_auto_tracker_qrcode_detector.dir/flashcode_mbt/detectors/qrcode/detector.cpp.o] Error 1 make[2]: * Waiting for unfinished jobs.... make[1]: * [vision_visp/visp_auto_tracker/CMakeFiles/visp_auto_tracker_datamatrix_detector.dir/all] Error 2 make[1]: * Waiting for unfinished jobs.... make[1]: * [vision_visp/visp_auto_tracker/CMakeFiles/visp_auto_tracker_qrcode_detector.dir/all] Error 2 Linking CXX shared library /home/chaoqun/catkin_ws/devel/lib/libvisp_auto_tracker_cmd_line.so [ 90%] Built target visp_auto_tracker_cmd_line make: * [all] Error 2 Invoking "make" failed

I just do not know why,I really want to use this instrument,can you give me some hint?Thank you in advance!
