2017-03-27 10:07:06 -0500 asked a question 'Tracker': undeclared identifier in (OpenCV with Extra Modules)

I got opencv 3.2 (with extra modules) built successfully in Visual Studio (2015). I am trying to build a code that uses the tracking module and especially the TrackerKCF. However, the compiler cannot recognize this library as appears in errors.

I have added the following dependencies in Linker>Input>Additional Dependencies:

opencv_aruco320d.lib opencv_bgsegm320d.lib opencv_bioinspired320d.lib opencv_calib3d320d.lib opencv_ccalib320d.lib opencv_core320d.lib opencv_datasets320d.lib opencv_dnn320d.lib opencv_dpm320d.lib opencv_face320d.lib opencv_features2d320d.lib opencv_flann320d.lib opencv_fuzzy320d.lib opencv_hdf320d.lib opencv_highgui320d.lib opencv_imgcodecs320d.lib opencv_imgproc320d.lib opencv_line_descriptor320d.lib opencv_ml320d.lib opencv_objdetect320d.lib opencv_optflow320d.lib opencv_phase_unwrapping320d.lib opencv_photo320d.lib opencv_plot320d.lib opencv_reg320d.lib opencv_rgbd320d.lib opencv_saliency320d.lib opencv_shape320d.lib opencv_stereo320d.lib opencv_stitching320d.lib opencv_structured_light320d.lib opencv_superres320d.lib opencv_surface_matching320d.lib opencv_text320d.lib opencv_tracking320d.lib opencv_video320d.lib opencv_videoio320d.lib opencv_videostab320d.lib opencv_xfeatures2d320d.lib opencv_ximgproc320d.lib opencv_xobjdetect320d.lib opencv_xphoto320d.lib

Part of Code:

        delay_toDeleteinFrame.insert(delay_toDeleteinFrame.end(), 0);
        Rect a;
        a.x = a.y = a.height = a.width = 0;
        group_whenOcclusion.insert(group_whenOcclusion.end(), a);
        TrackerKCF::Params param;
        param.desc_pca = TrackerKCF::MODE::CN | TrackerKCF::MODE::GRAY;
        Ptr<TrackerKCF> tracker = TrackerKCF::createTracker(param);

        //Ptr<Tracker> tracker = Tracker::create("KCF");
        tracker_vector.insert(tracker_vector.end(), tracker);

Errors:

Error   C2653   'TrackerKCF': is not a class or namespace name
Error   C2065   'Tracker': undeclared identifier
Error   C2923   'cv::Ptr': 'TrackerKCF' is not a valid template type argument for parameter 'T'

What could I be missing here?

Thanks in advance

Thanks @LBerger , disabling hdf and python has solved the problem

I have configured and generated opencv 3.2 with extra modules on CMAKE successfully using a 32-bit compiler of Visual Studio 2015 (vs14). However, when building this project in Visual Studio I get several errors. Below, you could find: small sample of the errors, the CMake ouput , the set of all errors,

Dear @Tetragramm , Following are lines of the code around the error:

        Rect a;
        a.x = a.y = a.height = a.width = 0;
        group_whenOcclusion.insert(group_whenOcclusion.end(), a);
        TrackerKCF::Params param;
        param.desc_pca = TrackerKCF::MODE::CN | TrackerKCF::MODE::GRAY;
        Ptr<TrackerKCF> tracker = TrackerKCF::createTracker(param);

        //Ptr<Tracker> tracker = Tracker::create("KCF");
        tracker_vector.insert(tracker_vector.end(), tracker);

        vector<Rect> rect_save;

Thanks much

I managed to fix the libopencv_tracking.so error from this link: http://stackoverflow.com/questions/19164343/opencv-libopencv-core-so-2-4-cannot-open-shared-object-file-no-such-file-or (http://stackoverflow.com/questions/19...)

However, now kcf.cpp compiles and I have replaced the file with the file I want to run as you have suggested, but I still get the original error here:

error: ‘cv::TrackerKCF::MODE’ is not a class or namespace param.desc_pca = TrackerKCF::MODE::CN | TrackerKCF::MODE::GRAY;

========================================== Thanks much for help so far

@LBerger, sorry I think I did not give the right answer. When I run opencv_contrib/modules/tracking/samples/kcf.cpp in this directory I get the following error: "error while loading shared libraries: libopencv_tracking.so.3.2: cannot open shared object file: No such file or directory " And I actually have more than one opencv version, but I'm only interested in the latest 3.2

2017-02-12 14:11:10 -0500 commented question Error in Using TrackerKCF in Ubuntu /Linux

Yes I can. I expect something like a syntax difference when using TrackerKCF::Mode, or in including the required libraries for it in Ubuntu?

2017-02-12 13:48:17 -0500 commented question Error in Using TrackerKCF in Ubuntu /Linux

Yes they all exist actually

2017-02-12 13:07:17 -0500 commented question Error in Using TrackerKCF in Ubuntu /Linux

Thanks. How could I determine or check that?

2017-02-12 12:35:14 -0500 asked a question Error in Using TrackerKCF in Ubuntu /Linux

I have built successfully OpenCV 3.2 with the extra modules contribution successfully on Ubuntu. However, I'm having an error when building a code that uses (TrackerKCF::MODE), although this code was compiled successfully on Windows. Is there some syntax or includes I need to change or add?
