Basic MainWindowTutorial Compilation Errors!

General JUCE discussion

Hey, I am trying to do the basic MainWindow tutorial which is apparently on the website. and following the instructions, I have the following error code.

1>------ Build started: Project: MainWindowTutorial_App, Configuration: Debug x64 ------

Replacing the ScopedPointer with std::unique_ptr can solve the problem but can someone explain why is that? and why if that’s the solution, it’s not updated in the tutorial page. Also I am getting unreferenced formal parameter in the commandLine .

Code:

    }

    void anotherInstanceStarted (const String& commandLine) override
    {
        // When another instance of the app is launched while this one is running,

Those are warnings, not errors. But yes I’ll get those ScopedPointer instances cleaned up, we deprecated that class a while ago in favour of std::unique_ptr and I thought we’d got rid of them all!
