Problem Installing realsense_samples_ros

[mirirjakys]

Hi,

I am the happy owner of two Intel Robotic Development Kits, using the R200 with the Up board and running Ubuntu 16.04.03.

In one of the UP boards, I have been able to successfully install the realsense_samples_ros packages following the instructions on the README, but in the other UP board, I struggle to make catkin_make compile, and I don't know why as it seems to be exactly the same platform, same OS and same packages.

This is the error that catkin_make outputs:

[ 92%] Linking CXX executable /home/salup/catkin_ws/devel/lib/realsense_ros_person/realsense_ros_person_sample [ 98%] Built target realsense_ros_person CMakeFiles/realsense_ros_person_sample.dir/src/sample/TrackingRenderer/Viewer.cpp.o: In function Viewer::Viewer(bool)': Viewer.cpp:(.text+0x97): undefined reference tocv::namedWindow(cv::String const&, int)' Viewer.cpp:(.text+0xc9): undefined reference to cv::setMouseCallback(cv::String const&, void (*)(int, int, int, int, void*), void*)' Viewer.cpp:(.text+0xda): undefined reference tocv::startWindowThread()' Viewer.cpp:(.text+0x106): undefined reference to cv::namedWindow(cv::String const&, int)' Viewer.cpp:(.text+0x117): undefined reference tocv::startWindowThread()' CMakeFiles/realsense_ros_person_sample.dir/src/sample/TrackingRenderer/Viewer.cpp.o: In function Viewer::ShowImage(cv::Mat)': Viewer.cpp:(.text+0x1dd): undefined reference tocv::imshow(cv::String const&, cv::_InputArray const&)' Viewer.cpp:(.text+0x1ff): undefined reference to cv::waitKey(int)' CMakeFiles/realsense_ros_person_sample.dir/src/sample/TrackingRenderer/Viewer.cpp.o: In functionViewer::ShowDepth(cv::Mat)': Viewer.cpp:(.text+0x29f): undefined reference to `cv::imshow(cv::String const&, cv::_InputArray const&)' collect2: error: ld returned 1 exit status realsense_samples_ros/realsense_ros_person/CMakeFiles/realsense_ros_person_sample.dir/build.make:209: recipe for target '/home/salup/catkin_ws/devel/lib/realsense_ros_person/realsense_ros_person_sample' failed make[2]: [/home/salup/catkin_ws/devel/lib/realsense_ros_person/realsense_ros_person_sample] Error 1 CMakeFiles/Makefile2:399: recipe for target 'realsense_samples_ros/realsense_ros_person/CMakeFiles/realsense_ros_person_sample.dir/all' failed make[1]: [realsense_samples_ros/realsense_ros_person/CMakeFiles/realsense_ros_person_sample.dir/all] Error 2 Makefile:138: recipe for target 'all' failed make: *** [all] Error 2 Invoking "make -j4 -l4" failed

Could anybody give me a hand with it?

Thanks in advance, Marcos

I think it lose a package in realsense_ros_person/CMakeLists.txt, add to “find_package(OpenCV REQUIRED)“ ,it will be passed。
