Golang 编译成DLL文件的操作_Golang_

 package main import "C" import "fmt" //export PrintBye func PrintBye() { fmt.Println("From DLL: Bye!") } //export Sum func Sum(a int, b int) int { return a + b; } func main() { // Need a main function to make CGO compile package as C shared library } 

 go build -buildmode=c-shared -o exportgo.dll exportgo.go

 package main import ( "net" ) //必须导入 import "C" //编译成动态库也是必须的 func main() {} //export Interfaces func Interfaces(list []string, retlen *int) string { interf, err := net.InterfaceAddrs() if err != nil { return err.Error() } for i, v := range interf { if i >= len(list) { break } list[i] = v.String() } *retlen = len(list) return "" } 

 go build -ldflags "-s -w" -buildmode=c-shared -o net.dll main.go
