Hey all, pretty new to go and having a problem with go get on MacOS 12.2/Go 1.17.6 on M1.

Here is what I am facing:

face-detector % go get github.com/Kagami/go-face 
# github.com/Kagami/go-face
clang: error: the clang compiler does not support '-march=native'

I am not sure if I am missing some flag that would allow this to build. Here is my go env:

face-detector % go env

Any recommendations? I am not seeing where -march=native is set. There was a stack overflow thread that suggested using -mcpu=apple-m1 however I am not seeing where to put that.

modify face.go at this project

package face

// #cgo CXXFLAGS: -std=c++1z -Wall -O3 -DNDEBUG -mcpu=apple-m1

another solutions is update clang with brew

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

1° - Install llvm con brew
brew install llvm
2° - Check clang version

cd /opt/homebrew/opt/llvm
.clang --version

Result:

Homebrew clang version 15.0.6
Target: arm64-apple-darwin22.2.0
Thread model: posix
InstalledDir: /opt/homebrew/opt/llvm/bin

3° - modify path with the new version, for example add to .zshrc
export PATH="/opt/homebrew/opt/llvm/bin:$PATH"

I tried the solution above, and now it gets an error

classify.cc:2:10: fatal error: 'dlib/graph_utils.h' file not found

try

Same error here, even with setting LIBRARY_PATH (for me, CPLUS_INCLUDE_PATH and LD_LIBRARY_PATH were already setup correctly).
Any hints @chaosue @Kagami @gougo @Exegetech @nodoyuna @dtaivpp ?

adrien3d commented

Fixed by copying dlib in $GOPATH/pkg/path/to/go-faceand changing import in classify.cc
