Exemple not compiling

[Philippe Richard]

Hi  peop, 

When I try to compile this code with node-gyp rebuild, i get the errors : 

'HandleScope' undeclared identifier

'scope': identifier not found

'GetCurrentContext' is not a member of v8 function

v8::Function::Call : take 3 args does not take 3 args

Help please : I'm using node v12.24.1

Thanks

static Persistent<v8::Function> cb; 

void PostMessage(){

 

Isolate* isolate = Isolate::GetCurrent(); v8::Locker locker(isolate); 

 HandleScope scope(isolate);

const unsigned argc = 1; Local<Value> argv[argc] = { 

String::NewFromUtf8(isolate, "test") }; 

 Local<v8::Function> PostMessageCb = Local<v8::Function>::New(isolate, cb);

(PostMessageCb)->Call(isolate->GetCurrentContext()->Global(), argc, argv); } 

//-------------------------------------------------------------------------------------------------------------------//

void SetupCallback(const FunctionCallbackInfo<Value>& args) { 

 Isolate* isolate = Isolate::GetCurrent(); 

 v8::Locker locker(isolate); HandleScope scope(isolate);

 

Local<v8::Function> local_cb = Local<v8::Function>::Cast(args[0]); cb.Reset(isolate, local_cb); } 

Error code :
