OpenCV4를 이용, MacOS app만들기 (catalina)

연구관련 프로젝트로 openCV를 이용할 일이 있어서, openCV를 공부하고

간단한 프로그램을 만들게되었는데,

공식적으로 MacOS app을 만들기 위한 라이브러리가 존재하지 않고

구글링으로 정확하게 방법을 다루는 글이 없어서 정리함

 

1. Homebrew install

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

 

2. Install opencv (aka opencv@4)

brew install opencv 

 

3. XCode 설정

Project -> build settings에서

3.1. Header search path (4.x.x는 알맞은 버젼번호로 바꾸기, recursive로 설정)

/usr/local/Cellar/opencv/4.x.x/include

3.2. Library search path (4.x.x는 알맞은 버젼번호로 바꾸기, recursive로 설정)

usr/local/Cellar/opencv/4.x.x/lib

3.3. Other Linker Flags

Terminal에서 

pkg-config --cflags --libs opencv4

했을때 나오는 flag들을 모두 Other Linker Flags에 입력함. (아래는 예시)

-I/usr/local/Cellar/opencv/4.1.2/include/opencv4/opencv -I/usr/local/Cellar/opencv/4.1.2/include/opencv4 -L/usr/local/Cellar/opencv/4.1.2/lib -lopencv_gapi -lopencv_stitching -lopencv_aruco -lopencv_bgsegm -lopencv_bioinspired -lopencv_ccalib -lopencv_dnn_objdetect -lopencv_dpm -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_highgui -lopencv_dnn -lopencv_plot -lopencv_videostab -lopencv_video -lopencv_videoio -lopencv_xfeatures2d -lopencv_shape -lopencv_ml -lopencv_ximgproc -lopencv_xobjdetect -lopencv_objdetect -lopencv_calib3d -lopencv_imgcodecs -lopencv_features2d -lopencv_flann -lopencv_xphoto -lopencv_photo -lopencv_imgproc -lopencv_core
