What did you do?

1. I have a project with a single go file in it.

package main
import "C"
import (
	"fmt"

	"github.com/99designs/keyring"
)
func Get() {
	ring, _ := keyring.Open(keyring.Config{
		ServiceName: "example",
	})
	_ = ring.Set(keyring.Item{
		Key:  "foo",
		Data: []byte("secret-bar"),
	})
	i, _ := ring.Get("foo")

	fmt.Printf("%s", i.Data)
}
func main() {}

3. This project imports several other dependencies like:
   github.com/99designs/go-keychain v0.0.0-20191008050251-8e49817e8af4 // indirect
   github.com/99designs/keyring v1.2.2
   github.com/danieljoos/wincred v1.1.2 // indirect
   github.com/dvsekhvalnov/jose2go v1.5.0 // indirect
   github.com/godbus/dbus v0.0.0-20190726142602-4481cbc300e2 // indirect
   github.com/gsterjov/go-libsecret v0.0.0-20161001094733-a6f4afe4910c // indirect
   github.com/mtibben/percent v0.2.1 // indirect
   golang.org/x/sys v0.5.0 // indirect
   golang.org/x/term v0.5.0 // indirect
4. If I build with this command go build -trimpath -buildmode=c-shared -ldflags '-w -s -extldflags "-lresolv"' -o keyring.so main.go it builds without error, but it does not generate a C header file and so I cannot use it.
5. However if I switch to a main file that does not have these external dependencies like this simple file, the exact same build command generates both the .so file and a header.

package main
import "C"
import (
	"sort"
	"sync"
)
var count int
var mtx sync.Mutex
//export Add
func Add(a, b int) int {
	return a + b
}
//export Sort
func Sort(vals []int) {
	sort.Ints(vals)
}
func main() {}

What did you expect to see?

I expected item 4 to generate a C header too

What did you see instead?

Only a .so file was generated
