I keep getting an error when using: ui->setupUi(this) error If anyone knows what the error might be, I would be very grateful.

MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::MainWindow)
{
   ui->setupUi(this); // This is where the error occurs 
   scanningNow = false;
   setBackground = false;
   displayRef = false;
   fileName = "NIR Spectra";
   initCalib();
   initSettings();

   initUI();
   USB_Init();

   emit checkUSB();

   #ifdef USB_POLL_ENABLED
      usbPollTimer = new QTimer(this);
      usbPollTimer -> setInterval(5000);
      connect(usbPollTimer, SIGNAL(timeout()), this, SLOT(timerTimeout()));
      usbPollTimer -> start();
   #endif

}

The error is: 'cannot initialize object parameter of type 'Ui_MainWindow' with an expression of type 'Ui::MainWindow'

Did you change manually the ui_mainwindow.h file that is automatically made by by Moc? – Gabriella Giordano Jun 19 '18 at 13:19
@GabriellaGiordano That file is made by `uic`, not moc. – Kuba hasn't forgotten Monica Jun 19 '18 at 17:48
@Kuba Ober correct. My bad :) but still the question remains... – Gabriella Giordano Jun 19 '18 at 17:54
Did you ever find a solution to this? I have the same issue. No qmake or compile errors when I actually build the project but it's very annoying nonetheless. – Layne Bernardo Jan 14 '19 at 02:05
