Missing template instantiation

General JUCE discussion

template <typename ValueType>
Point<ValueType> Displays::logicalToPhysical (Point<ValueType> point, const Display* useScaleFactorOfDisplay)  const noexcept
{
    auto& display = useScaleFactorOfDisplay != nullptr ? *useScaleFactorOfDisplay
                                                       : findDisplayForPoint (point.roundToInt(), false);

    auto globalScale = Desktop::getInstance().getGlobalScaleFactor();

    Point<ValueType> logicalTopLeft  (display.totalArea.getX(),       display.totalArea.getY());
    Point<ValueType> physicalTopLeft (display.topLeftPhysical.getX(), display.topLeftPhysical.getY());

    return ((point - (logicalTopLeft * globalScale)) * (display.scale / globalScale)) + physicalTopLeft;
}

as per @Rail_Jon_Rogut this causes a linker error:

Displays::Display mainDisplay = Desktop::getInstance().getDisplays().getMainDisplay();

Point&lt;int&gt; coordinates = { 100, 100 };

coordinates = Desktop::getInstance().getDisplays().logicalToPhysical (coordinates, &amp;mainDisplay);

Looks like you guys forgot to explicitly instantiate the template in the cpp file?

Compiles fine VS 2015 but fails to link in Xcode 8.x

fails to link on Xcode 10.1 too

Thanks, I’ll get that sorted out.
