The app was written in Qt5, but on the MacBook I only have macosx11.3 SDK, so had to try buidling using Qt 6.4.2.

The issue I am having is the error

Unknown module(s) in QT: script

I note that QScript is removed from Qt6.

QScript is used in only a few places in the code. I was wondering how the following would be replaced (not full code, but hope someone can give me pointers here).

FunctionPlotGraphicsView *view;
FunctionPlotData plot;
QScriptValue func;
QScriptEngine engine;
QScriptValueList args;
.
.

args << qreal_value;
qreal y = plot->func.call(QscritValue(), args).toNumber();

QScriptValue global = _view->engine.globalObject();
