CTinyJS not defined?

I have tried to compile TinyJS on my Mac, but got:

Script.cpp:50:5: error: use of undeclared identifier 'CTinyJS'; did you mean 'TinyJS'?
    CTinyJS *js = (CTinyJS*)userdata;
    ^~~~~~~
    TinyJS

namespace TinyJS {
          ^

    CTinyJS *js = (CTinyJS*)userdata;

    js->root->trace(">  ");

Should I use -DCTinyJS=TinyJS, maybe?

Get name of a cloned objects definition

Is there a way to get the name of an object? For e.g if i create an object like this

var myBaseObject = {
    name: "Test",
    value: 3
};

and now i want to get the name of the object myBaseObject. How can i do that? For e.g i want to write a function to tell me the name of the object

var test = myBaseObject.clone();
var theName = test.getObjectName();

Afterwards the variable theName should output myBaseObjetct.

Is that possible?

String.split

auto jsEngine = make_unique<CTinyJS>();
registerFunctions(jsEngine.get());
string js = "String('ape katt').split(' ');";
jsEngine->execute(js);

==> Error Expecting 'String' to be a function

Solution
replace in file Script.cpp line 50
CTinyJS *js = (CTinyJS*)userdata;
with
TinyJS::Interpreter *js = (TinyJS::Interpreter*)userdata;
