golang怎么编译调用dll文件

　　编译
　　exportgo.gopackage main  import ＂C＂  /*    export PrintBye 的意思是将PrintBye方法通过PrintBye名暴露出去 */ //export PrintBye func PrintBye() {    /*       这里是只能用println       不能用：log.Println()和fmt.Println()    */    println(＂From DLL: Bye!＂) }  //export Sum func Sum(a C.int, b C.int) C.int {    return a + b }  //export Sub func Sub(a C.int, b C.int) C.int {    return a - b }  //export Hello func Hello(a C.int, b C.int) C.int {    return a * b }  func main() {    // Need a main function to make CGO compile package as C shared library }
　　编译>go build -buildmode=c-shared -o exportgo.dll exportgo.go
　　编译完成后，生成exportgo.dll和exportgo.h调用
　　Called.gopackage main  import ＂C＂ import ( 	＂log＂ 	＂syscall＂ )  func main() { 	log.SetFlags(log.LstdFlags | log.Lshortfile) 	F4(50,30) 	F5(50,30) 	F6() } func F4(int1, int2 int) { 	log.Println(int1, int2) 	//引入dll文件方法1 	dll := syscall.MustLoadDLL(＂exportgo.dll＂) 	//使用完后要释放 	defer dll.Release() 	//调用dll的方法Sum 	proc := dll.MustFindProc(＂Sum＂) 	//使用sum函数，传递参数int1和int2 	call, u, err := proc.Call(uintptr(int1), uintptr(int2)) 	//输出结果call 	log.Println(call) 	log.Println(u) 	log.Println(err) } func F5(int1, int2 int) { 	//引入dll文件方法2 	dll := syscall.NewLazyDLL(＂exportgo.dll＂) 	//调用dll的方法Sub 	proc := dll.NewProc(＂Sub＂) 	//使用Sub函数，传递参数int1和int2 	r, err, msg := proc.Call(uintptr(int1), uintptr(int2)) 	//输出结果r 	log.Println(r) 	log.Println(err) 	log.Println(msg) } func F6() { 	//引入dll文件 	dll := syscall.NewLazyDLL(＂exportgo.dll＂) 	//调用dll的方法PrintBye 	proc := dll.NewProc(＂PrintBye＂) 	//调用dll的方法,不传递任何值 	r, err, msg := proc.Call() 	//输出结果r 	log.Println(r) 	log.Println(err) 	log.Println(msg) } 执行结果2022/03/26 14:48:00 Called.go:16: 50 30 2022/03/26 14:48:00 Called.go:26: 80 2022/03/26 14:48:00 Called.go:27: 8791506616320 2022/03/26 14:48:00 Called.go:28: The operation completed successfully. 2022/03/26 14:48:00 Called.go:38: 20 2022/03/26 14:48:00 Called.go:39: 8791503994880 2022/03/26 14:48:00 Called.go:40: The operation completed successfully.
