Unfortunately bug #631714 proposed a fix which broke compilation with opencv-3.1.0-r8. emerge -1O media-libs/mlt-6.4.1-r4 fails with: ... filter_opencv_tracker.cpp: In function ‘void analyze(mlt_filter, cv::Mat, private_data*, int, int, int, int)’: filter_opencv_tracker.cpp:114:43: error: no matching function for call to ‘cv::TrackerKCF::create()’ data->tracker = cv::TrackerKCF::create(); ^ In file included from /usr/include/opencv2/tracking.hpp:309:0, from filter_opencv_tracker.cpp:21: /usr/include/opencv2/tracking/tracker.hpp:563:31: note: candidate: static cv::Ptr<cv::Tracker> cv::Tracker::create(const cv::String&) CV_WRAP static Ptr<Tracker> create( const String& trackerType ); ^ /usr/include/opencv2/tracking/tracker.hpp:563:31: note: candidate expects 1 argument, 0 provided filter_opencv_tracker.cpp:118:43: error: no matching function for call to ‘cv::TrackerMIL::create()’ data->tracker = cv::TrackerMIL::create(); ^ In file included from /usr/include/opencv2/tracking.hpp:309:0, from filter_opencv_tracker.cpp:21: /usr/include/opencv2/tracking/tracker.hpp:563:31: note: candidate: static cv::Ptr<cv::Tracker> cv::Tracker::create(const cv::String&) CV_WRAP static Ptr<Tracker> create( const String& trackerType ); ^ /usr/include/opencv2/tracking/tracker.hpp:563:31: note: candidate expects 1 argument, 0 provided filter_opencv_tracker.cpp:122:48: error: no matching function for call to ‘cv::TrackerBoosting::create()’ data->tracker = cv::TrackerBoosting::create(); ^ In file included from /usr/include/opencv2/tracking.hpp:309:0, from filter_opencv_tracker.cpp:21: /usr/include/opencv2/tracking/tracker.hpp:563:31: note: candidate: static cv::Ptr<cv::Tracker> cv::Tracker::create(const cv::String&) CV_WRAP static Ptr<Tracker> create( const String& trackerType ); ^ /usr/include/opencv2/tracking/tracker.hpp:563:31: note: candidate expects 1 argument, 0 provided make[2]: *** [<builtin>: filter_opencv_tracker.o] Error 1
The easy way out - make it depend on >=opencv-3.3? Thomas, could you please test using opencv-3.2?
(In reply to Andreas Sturmlechner from comment #1) > The easy way out - make it depend on >=opencv-3.3? would be fine for me. > > Thomas, could you please test using opencv-3.2? compiles fine with opencv-3.2
