I am trying to build lsd_slam for ros kinetic in ubuntu 16.04, when i get the following error, home/dyana/catkin_make/devel/lib/liblsdslam.so: undefined reference to cv::_OutputArray::_OutputArray(cv::Mat&)' /home/dyana/catkin_make/devel/lib/liblsdslam.so: undefined reference tocv::line(cv::Mat&, cv::Point, cv::Point, cv::Scalar_ const&, int, int, int)' /home/dyana/catkin_make/devel/lib/liblsdslam.so: undefined reference to cv::_InputArray::_InputArray(cv::Mat const&)' /home/dyana/catkin_make/devel/lib/liblsdslam.so: undefined reference tocv::getOptimalNewCameraMatrix(cv::_InputArray const&, cv::InputArray const&, cv::Size, double, cv::Size, cv::Rect, bool)' /home/dyana/catkin_make/devel/lib/liblsdslam.so: undefined reference to cv::waitKey(int)' /home/dyana/catkin_make/devel/lib/liblsdslam.so: undefined reference tocv::namedWindow(cv::String const&, int)' /home/dyana/catkin_make/devel/lib/liblsdslam.so: undefined reference to cv::destroyAllWindows()' /home/dyana/catkin_make/devel/lib/liblsdslam.so: undefined reference tocv::resizeWindow(cv::String const&, int, int)' /home/dyana/catkin_make/devel/lib/liblsdslam.so: undefined reference to cv::imshow(cv::String const&, cv::_InputArray const&)' /home/dyana/catkin_make/devel/lib/liblsdslam.so: undefined reference tocv::putText(cv::Mat&, std::__cxx11::basic_string<char, std::chartraits, std::allocator > const&, cv::Point, int, double, cv::Scalar_, int, int, bool)' /home/dyana/catkin_make/devel/lib/liblsdslam.so: undefined reference to cv::_OutputArray::_OutputArray(cv::Mat&)' /home/dyana/catkin_make/devel/lib/liblsdslam.so: undefined reference tocv::line(cv::Mat&, cv::Point, cv::Point, cv::Scalar_ const&, int, int, int)' /home/dyana/catkin_make/devel/lib/liblsdslam.so: undefined reference to cv::_InputArray::_InputArray(cv::Mat const&)' /home/dyana/catkin_make/devel/lib/liblsdslam.so: undefined reference tocv::getOptimalNewCameraMatrix(cv::_InputArray const&, cv::InputArray const&, cv::Size, double, cv::Size, cv::Rect, bool)' /home/dyana/catkin_make/devel/lib/liblsdslam.so: undefined reference to cv::waitKey(int)' /home/dyana/catkin_make/devel/lib/liblsdslam.so: undefined reference tocv::namedWindow(cv::String const&, int)' /home/dyana/catkin_make/devel/lib/liblsdslam.so: undefined reference to cv::destroyAllWindows()' /home/dyana/catkin_make/devel/lib/liblsdslam.so: undefined reference tocv::resizeWindow(cv::String const&, int, int)' /home/dyana/catkin_make/devel/lib/liblsdslam.so: undefined reference to cv::imshow(cv::String const&, cv::_InputArray const&)' /home/dyana/catkin_make/devel/lib/liblsdslam.so: undefined reference tocv::putText(cv::Mat&, std::__cxx11::basic_string<char, std::chartraits, std::allocator > const&, cv::Point, int, double, cv::Scalar_, int, int, bool)'

How to resolve this issue?

@boonflies could you please check if you can use Kevin George's fork of LSD-SLAM for Ubuntu 16? From my knowledge, it's the best fork of LSD-SLAM specifically for use on Ubuntu 16 + ROS Kinetic. It saves a ton of time debugging!

I hope this helps! :)

@bespoke-code LSD-SLAM Kevin George's fork of LSD-SLAM for Ubuntu 16 works like a charm. Thanks
