Example
package main
import "fmt"
var V int
func F() { fmt.Printf("Hello, number %d\n", V) }
This can be built with:
go build -buildmode=plugin
And then loaded and used from your application:
p, err := plugin.Open("plugin_name.so")
if err != nil {
panic(err)
}
v, err := p.Lookup("V")
if err != nil {
panic(err)
}
f, err := p.Lookup("F")
if err != nil {
panic(err)
}
*v.(*int) = 7
f.(func())() // prints "Hello, number 7"
Example from The State of Go 2017.
