I wrote go code on macos(m2) using aws-sdk-cpp and libtorch(cpp) through cgo but got an errormessage: [ld: symbol(s) not found for architecture arm64]

Question

my cgo args:

/*
#cgo LDFLAGS: -L/usr/local/libtorch/lib -ltorch -lc10 -lkineto -ltorch_cpu -laws-cpp-sdk-s3 -laws-cpp-sdk-sts -laws-cpp-sdk-iam -laws-cpp-sdk-core
#cgo CXXFLAGS: -std=c++14 -I/usr/local/libtorch/include -v // I added -arch arm64 but not working
#include "NDInferenceModel_capi.h"
*/
import "C"

This is my zsh output.

The full output is here.

zsh and output:

I added -arch arm64 to #cgo CXXFLAGS but not working.

I added -arch arm64 to #cgo CXXFLAGS but not working. I hope I can use go run main.go to compile code normally.
