class "cv::Tracker" has no member "create"?

edit

Thanks I change it to Ptr<tracker> tracker = TrackerKCF::create(); but also I got errors even I put libraries in additional dependencies .

Error LNK2019 unresolved external symbol "public: bool __cdecl cv::Tracker::init(class cv::debug_build_guard::_InputArray const &,class cv::Rect_<double> const &)" (?init@Tracker@cv@@QEAA_NAEBV_InputArray@debug_build_guard@2@AEBV?$Rect_@N@2@@Z) referenced in function main

Error LNK1120 3 unresolved externals

you need to link -lopencv_tracking

sorry what is -lopencv_tracking ?

(facepalm) -- you need to link a library for this.

and sorry, i did not see (and you never told us) that you're using VS in windows, so you have to add something like

opencv_tracking34?.lib to your "additional libraries list"

sorry yes I am using VS 2015 in windows 10 I got that The program '[8864] tracking.exe' has exited with code -1073741515 (0xc0000135) 'A dependent dll was not found'
