📺 OpenCV C++ Mac M1 Installation Tutorial Video
We need homebrew installed in our system
brew install cmake
mkdir Open_CV && cd Open_CV
git clone https://github.com/opencv/opencv.git
mkdir build && cd build
cmake ../opencv/ .
arch -arm64 cmake ../opencv/ -DWITH_QT=OFF -DWITH_OPENGL=OFF -DFORCE_VTK=OFF -DWITH_TBB=OFF -DWITH_GDAL=OFF -DWITH_XINE=OFF -DBUILD_EXAMPLES=OFF -DBUILD_ZLIB=OFF -DBUILD_TESTS=OFF .
arch -arm64 sudo make -j 4
arch -arm64 sudo make install
Hi @nucliweb
Sorry for bothering. I went into the video tutorial and I managed to understand how compilation is done (using CMakeLists and makefiles). I had just compiled using the g++ command and therefore the libraries had not been included properly.
Thank you.
Great! 🚀
Great! thank you!
@henrydrp10 may you please share a link to the video tutorial? I faced the same issue
I ran the command: arch -arm64 sudo make -j$(nproc) and got the following output:

Anyone has idea about how to fix this?

Thank you for the reply! Yes I am using the latest macOS (Sonoma 14.5 arm64) with a clean install from 2 weeks ago. So as for as I know from partial discussion in opencv/opencv#25625 and opencv/opencv#25625, an update is needed for the opencv repo, and it's not an issue of my environment, isn't it? Anyway, thank you for remaindering me here. I could offer any help if action is needed.
p.s. I used
brew install opencvto solve this days ago
yes a pull was made a few days ago that fixes your error.
I don't know how brew works and how often they update the code.
What you should do is download and install OpenCV by hand.
To do that it seems to me that the script here (and the small changes suggested) should be fine.

Hello, I dont know if you have already solve this problem or not, but the way I solve is by reinstall homebrew and make sure you are installing the arm version instead of X86

Hello, I solved it by building the source code instead of using brew at that time. Thank you for your reminder, which I believe will help others.

Hi @henrydrp10
Can you share the system and hardware that you are using?
