So after using 

pkg-config --cflags --libs opencv4

I get 

-I/usr/local/Cellar/opencv/4.2.0_1/include/opencv4/opencv -I/usr/local/Cellar/opencv/4.2.0_1/include/opencv4 -L/usr/local/Cellar/opencv/4.2.0_1/lib -lopencv_gapi -lopencv_stitching -lopencv_aruco -lopencv_bgsegm -lopencv_bioinspired -lopencv_ccalib -lopencv_dnn_objdetect -lopencv_dnn_superres -lopencv_dpm -lopencv_highgui -lopencv_face -lopencv_freetype -lopencv_fuzzy -lopencv_hfs -lopencv_img_hash -lopencv_line_descriptor -lopencv_quality -lopencv_reg -lopencv_rgbd -lopencv_saliency -lopencv_sfm -lopencv_stereo -lopencv_structured_light -lopencv_phase_unwrapping -lopencv_superres -lopencv_optflow -lopencv_surface_matching -lopencv_tracking -lopencv_datasets -lopencv_text -lopencv_dnn -lopencv_plot -lopencv_videostab -lopencv_videoio -lopencv_xfeatures2d -lopencv_shape -lopencv_ml -lopencv_ximgproc -lopencv_video -lopencv_xobjdetect -lopencv_objdetect -lopencv_calib3d -lopencv_imgcodecs -lopencv_features2d -lopencv_flann -lopencv_xphoto -lopencv_photo -lopencv_imgproc -lopencv_core

Header search path 

/usr/local/Cellar/opencv/4.2.0_1/include/opencv4

Library search paths

/usr/local/Cellar/opencv/4.2.0_1/lib

Other linker flags 

-lopencv_gapi -lopencv_stitching -lopencv_aruco -lopencv_bgsegm -lopencv_bioinspired -lopencv_ccalib -lopencv_dnn_objdetect -lopencv_dnn_superres -lopencv_dpm -lopencv_highgui -lopencv_face -lopencv_freetype -lopencv_fuzzy -lopencv_hfs -lopencv_img_hash -lopencv_line_descriptor -lopencv_quality -lopencv_reg -lopencv_rgbd -lopencv_saliency -lopencv_sfm -lopencv_stereo -lopencv_structured_light -lopencv_phase_unwrapping -lopencv_superres -lopencv_optflow -lopencv_surface_matching -lopencv_tracking -lopencv_datasets -lopencv_text -lopencv_dnn -lopencv_plot -lopencv_videostab -lopencv_videoio -lopencv_xfeatures2d -lopencv_shape -lopencv_ml -lopencv_ximgproc -lopencv_video -lopencv_xobjdetect -lopencv_objdetect -lopencv_calib3d -lopencv_imgcodecs -lopencv_features2d -lopencv_flann -lopencv_xphoto -lopencv_photo -lopencv_imgproc -lopencv_core

But even after adding them to my header search paths, library search paths and other linker flags I still get this error

  • Tried them but the error still exist –  Feb 13 '20 at 07:26
  • Try searching for it in Terminal `find /usr -name opencv.hpp` – Mark Setchell Feb 13 '20 at 08:26
  • Maybe it's `opencv2/core.hpp` now – Mark Setchell Feb 13 '20 at 08:29
  • Are you sure you installed OpenCV correctly? Please try ```pkg-config --modversion opencv``` and be sure it exist firstly. – Yunus Temurlenk Feb 13 '20 at 08:36

  • @YunusTemurlenk `(base) Yudhieshs-MacBook-Pro:C:C++ yudhiesh$ pkg-config --modversion opencv Package file '/usr/local/lib/pkgconfig/opencv.pc' appears to be empty Package 'opencv' has no Name: field` What should I do here ? –  Feb 13 '20 at 10:12
  • Please show the actual full command you are using to compile/link - by editing your question - not in the comments area. – Mark Setchell Feb 13 '20 at 10:13
  • @yuRa Then your installation wrong. OpenCV doesnt exist. – Yunus Temurlenk Feb 13 '20 at 10:17
  • When you installed OpenCV first check its existance – Yunus Temurlenk Feb 13 '20 at 10:18
  • @YunusTemurlenk ok do you know any tutorials to install it then? –  Feb 13 '20 at 10:37
  • I can suggest [this](https://www.learnopencv.com/install-opencv3-on-macos/) – Yunus Temurlenk Feb 13 '20 at 10:43
  • @YunusTemurlenk I completed it but still getting the same error –  Feb 13 '20 at 14:06
