Can you compile OpenCV Source (in arm64) on Apple M1?

Another Simple Answer: YES!

In my last post, I tried to get OpenCV — x86-64 running on Apple M1.

Can I compile OpenCV source on Apple M1 Chip?

Simple answer: Yes, OpenCV can be compiled in x86-64 with Rosetta.

opencv/opencv

Here I just compile again natively.

git clone https://github.com/opencv/opencv
cd opencv
mkdir build_arm64
cd build_arm64
cmake ../
make -j 9

Again, a little while later. It is compiled successfully.

Ok, basically nothing to see here. It all works as expected. In conclusion, I could switch between two architectures without thinking much about it. If you are linking applications using dynamic linking, then it will be a management nightmare. Good luck here!
