Cgo link error on macOS

[wewindy]

I add this package to my simple go package:

go get github.com/qmuntal/draco-go

And I use the starter code from README:

package main

import (
	"fmt"
	"os"

	"github.com/qmuntal/draco-go/draco"
)

func main() {
  data, _ := os.ReadFile("./testdata/test_nm.obj.edgebreaker.cl4.2.2.drc")
  m := draco.NewMesh()
  d := draco.NewDecoder()
  d.DecodeMesh(m, data)
  fmt.Println("nº faces:", m.NumFaces())
  fmt.Println("nº points:", m.NumPoints())
  faces := m.Faces(nil)
  for i, f := range faces {
    fmt.Printf("%d: %v\n", i, f)
  }
}

When I run go build, report some warnings and errors:

/usr/local/go/pkg/tool/darwin_arm64/link: running clang failed: exit status 1
ld: library 'draco_c' not found
clang: error: linker command failed with exit code 1 (use -v to see invocation)

My platform:

• macOS 15
• chip: m2 (arm64)
• go version: 1.20
• gcc: Apple clang version 16.0.0 (clang-1600.0.26.3)
