Hi tysik!
Thanks for your package of obstacle detector.
I've found a problem in file obstacle_extractor.h, line 43 "#include <obstacle_detector/Obstacles.h>". But I can't find this file "Obstacles.h" in corresponding directory. Could you tell me where it is? Thx!

Obstacles.h is automatically generated by catkin from messages description files *.msg. You should not edit these header files on your own. Please try to call catkin_make couple of times or comment out obstacle_extractor and tracker from CMakeList.txt for the first build.

Thx very much! btw, can this package be applied to Lidar on vehicles? Just detect the obstacles on road.

We found that adding set(catkin_EXPORTED_TARGETS ${catkin_EXPORTED_TARGETS} obstacle_detector_generate_messages_cpp) before # Build libs in obstacle_detector/CMakeLists.txt seems to fix this issue. Now our workspace builds with a single catkin_make call.
And it is said here that you need to add an explicit dependency to the generated headers.

Seems to fix issue tysik#10.

Sometimes, when building with `catkin_make`, we used to get this error:
        In file included from /home/src/obstacle_detector/src/displays/circle_visual.cpp:36:0:
        /home/src/obstacle_detector/include/obstacle_detector/displays/circle_visual.h:39:10: fatal error: obstacle_detector/Obstacles.h: No such file or directory
Now our workspace builds with a single catkin_make call.
