The terminal entering the OpenCV source code under the terminal.exist ~/Library/Caches/HomebrewIn the directory, there is a BREW download cache, search opencvYou can find TAR compressed files of OpenCV and OpenCV_Contrib Get the source code: No need to download it from the official website.set up Search PathWhen the directory should be shown below:Įxecute test code, you can figure out.First import dylibWhen the file is file, the directory should be above /libFolder.This is related to Xcode configuration needs to be changed: lib: Configuration Library PathIt is this directory.This not only contains OpenCV's header file, more like videoio, surface_matchingWait for folders and files from the Contrib library include/opencv4/opencv2: C ++ #include It is here a directory.Here only include/opencv4/opencv2and libPart of the content under the folder, we can probably see: HOMEBREW installed package /opt/homebrew/CellarNext, OpenCV is no exception, specifically /opt/homebrew/Cellar/opencv/4.5.1_2The file structure is as follows: 4.5.1_2 On the MacBook Air With M1, the download package file + compile time is about 7 minutes Directory analysis after installationĪt this stage, the installation directory of M1 native homebrew can only be /opt/homebrew. I have stayed in this place for a long time, looking for how to compile, and later I saw this file in the official document, solved my own problems.

So, HomeBrew defaults OpenCV_ContribNo need to consider recompiling OpenCV + OpenCV_Contrib, which is why BREW installation is the easiest way. Chapter 72: Enabled opencv_contribCompilation.Chapter 71: Enabled non-freeCompilation of the algorithm.See here: This is the command executed when using the BREW installation, we can see it downloaded opencvand opencv_contribTwo packages, and view the cmake directive, let's take a few to see: Use HomeBrew installation directly: brew install -s opencv Problems about OpenCV_Contrib Current latest version: OpenCV4.5.1 + OpenCV_Contrib4.5.1 OpenCV4.5.1 installation
