Error while building on Mac OS with M1 chipset

[bahadirbk]

Dear @TadasBaltrusaitis,

I need to use openface tool for my project. I have installed and ran it successfully on Ubuntu before but now I need to use it on Mac OS. I did what @ThomasJanssoone suggested here to install in on mac but I' m having an issue while building it. I have M1 Mac so the architecture is arm64 here. I've shared the error below. Please help me. Many thanks in advance!

When I do 'make' in the build folder, I got this error:

objc[52417]: Class AMSupportURLConnectionDelegate is implemented in both /usr/lib/libamsupport.dylib (0x210af7678) and /Library/Apple/System/Library/PrivateFrameworks/MobileDevice.framework/Versions/A/MobileDevice (0x10aee82c8). One of the two will be used. Which one is undefined. objc[52417]: Class AMSupportURLSession is implemented in both /usr/lib/libamsupport.dylib (0x210af76c8) and /Library/Apple/System/Library/PrivateFrameworks/MobileDevice.framework/Versions/A/MobileDevice (0x10aee8318).

hello,

it looks like an openBlas install error. I am not sure but I think it has a different configuration for M1 chip. You can check this thread for more details.

@ThomasJanssoone so the solution is to build openblas for our apple silicon to make it work ?
