You lose a bit of control (as compared to compiling from source), but what you gain is an easier to follow path to installing OpenCV on your Mac system. Well, there’s a little more to it than that… but the process is greatly simplified. So, is it really that easy? Just can a few simple keystrokes and commands can be used to avoid the hassle and install OpenCV 3 without the headaches? It turns out, there is - just use Homebrew, what many consider to be “the missing package manager for Mac”. “Is there an easier way to install OpenCV on macOS? A way that avoids the complicated CMake configuration?” The downside is that determining the correct CMake paths to your Python interpreter, libraries, and include directories can be non-trivial, especially for users who are new to OpenCV/Unix systems. Over the past few weeks I have demonstrated how to compile OpenCV 3 on macOS with Python ( 2.7, 3.5) bindings from source.Ĭompiling OpenCV via source gives you complete and total control over which modules you want to build, how they are built, and where they are installed.Īll this control can come at a price though.

I extracted that, and in the file task_group.Click here to download the source code to this post In that folder is a symlink tbb-2019_U1.tar.gz which pointed to a file located in /Users//Library/Caches/Homebrew/downloads. For me it was: /Users//Library/Caches/Homebrew.
The source code is cached by Homebrew and the path to the location can be found using the command brew -cache. You are responsible for resolving any issues you experience.Īfter some searching I found this thread which made me think I could solve this if I had access to the source.
