Can't build on M1 Mac

[RyannDaGreat]

Hi,
When I run the command

build make -j4

I get the error

clang: error: the clang compiler does not support '-march=native'

Here's the full output:

➜ build make -j4

I'm on a M1 Mac Max 16 inch.

I tried this with two versions of clang; the first one being the one that is installed with xcode:

➜ macx-stable-diffusion > clang -v
Apple clang version 13.1.6 (clang-1316.0.21.2.5)
Target: arm64-apple-darwin21.5.0
Thread model: posix
InstalledDir: /Library/Developer/CommandLineTools/usr/bin

and then one installed with brew via brew install llvm:

➜ build clang -v
Homebrew clang version 15.0.0
Target: arm64-apple-darwin21.5.0
Thread model: posix
InstalledDir: /opt/homebrew/opt/llvm/bin

I was able to get this library to work on my Intel 2013 macbook, but not the 2021 16 inch Mac Max.

What am I doing wrong?

Update: This was solved by removing -march=native from line 11 of CMakeLists.txt. Should I make a pull request?
