go开发中引用静态库.a文件的方法

package demo

import (
	"fmt"
)

func Demo() {
	fmt.Printf("hello world")
}

package main

import "demo"

func main() {
	demo.Demo()
}

//go:binary-only-package

package demo

import (
	_ "fmt"
)

func Demo() {
}

//	//go:binary-only-package
//
//	package mypkg
//
// The source code may include additional Go code. That code is never compiled
// but will be processed by tools like godoc and might be useful as end-user
// documentation.
