SETTING UP OPENCV FOR MAC INSTALL
Firstly we need to download and install Xcode. "cv::imshow(std::string const&, cv::_InputArray const&)", referenced from: Steps for downloading and Installation of OpenCV in C++ on MacOS: Step 1: To start any kind of C/C++ development work on a MacOS.
"cv::imread(std::string const&, int)", referenced from:
"cv::Mat::deallocate()", referenced from: "cv::namedWindow(std::string const&, int)", referenced from: "cv::_InputArray::_InputArray(cv::Mat const&)", referenced from: Download the appropriate wheel (.whl) file, and install using pip. brew search opencv homebrew/science/opencv brew install homebrew/. python-OpenCV - There are alternative methods, but this is the easiest. Share answered at 21:15 oblitum 10.7k 5 51 119 The line 'brew install opencv' says permission denied'. Download latest source to /opt and: cd /opt tar -xzf OpenCV-2.2.0.tar.bz2 cd OpenCV-2.2. Undefined symbols for architecture x86_64: I struggled for a while with Python on Mac. 1 brew tap homebrew/science brew info opencv brew install opencv The info command was added as a suggestion so that you review the options you have when installing OpenCV.

I've tried various ways of specifying the lib path & libs in the project profile.
You’ll need to wait patiently as this figure indicates: Figure 1: Xcode is a dependency for Homebrew and therefore OpenCV 4 on macOS.
SETTING UP OPENCV FOR MAC PRO
Yes, you guessed it right - as of January 01, 2021, there’s no pre-compiled OpenCV binary compatible with this MacBook Pro variant. To install Xcode, fire up the Apple App Store, find the Xcode app, and install.
SETTING UP OPENCV FOR MAC HOW TO
I've written an extensive post about "what I have tried so far over at stackOverflow": Rather than repost all that here, the gist is that I don't seem to be linking to the OpenCV libs correctly. Note: If you dont feel like wasting time building stuff or dislike the terminal, you can most likely install OpenCV from the Synaptic package manager GUI. This post shows how to build and install OpenCV 4.5.0 on a MacBook Pro that comes with an M1 chip. Or, you may download XCode from Apple App Store -> find the XCode app -> install XCode.
SETTING UP OPENCV FOR MAC MAC OS X
Most of the information I've found on this pertains to Windows or Linux so I'm struggling. First, we need to install the latest XCode. Installing OpenCV is easy unless you want Version 3 (currently 3.0.0) with opencvcontribs for Python on Mac OS X (Yosemite). My outputs looks like this: -I/usr/local/Cellar/opencv/4.3.0_5/include/opencv4/opencv -I/usr/local/Cellar/opencv/4.3.0_5/include/opencv4 -L/usr/local/Cellar/opencv/4.3.0_5/lib -lopencv_gapi -lopencv_stitching -lopencv_alphamat -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_intensity_transform -lopencv_line_descriptor -lopencv_quality -lopencv_rapid -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 Create a C++ Project in Xcodeįirst, you should create a Command Line Tool project like this, and click next.I'm new to QT and am having trouble setting up OpenCV for use with QT under OSX.
