Hello Everyone,
I am doing some changes in d8.cc as needed by my project. For this I need
to add and register a C++ function which will be called in Javascript
source. This C++ function must return an integer. Here is my function (in
v8 namespace)
Local<Value> test (const FunctionCallbackInfo<Value>& args)
{
return args[0];
}
And Here is how I am registering it in CreateGlobalTemplate function of
Shell.
Local<ObjectTemplate> Shell::CreateGlobalTemplate(Isolate* isolate) {
Local<ObjectTemplate> global_template = ObjectTemplate::New(isolate);
global_template->Set(String::NewFromUtf8 (isolate, "test", NewStringType::
kNormal).ToLocalChecked(),
FunctionTemplate::New (isolate, test));
When I am making d8 I get the following errors
CXX(target) /home/abhi/ssl/v/v8/out/ia32.release/obj.target/d8/src/d8.o
../src/d8.cc: In static member function ‘static v8::Local<v8::ObjectTemplate

Can anyone please tell me what should be the function declaration if I need
to return a value. Any help will be highly appreciated.
Thank You,
Abhinav
