First - use CODE tags.

Second - your code is a mess.

Third - There's several issues with your code and the error messages tell you everything you need to know.

To make your code compile you need to change line

class modbusarm:public QMainWindow,public Ui_modbusarm::MainWindow

class modbusarm:public QMainWindow,public Ui_modbusarm::MainWindow

To copy to clipboard, switch view to plain text mode 

to

class modbusarm : public QMainWindow, public Ui_modbusarm

class modbusarm : public QMainWindow, public Ui_modbusarm

To copy to clipboard, switch view to plain text mode 

and delete line

~modbusarm();

~modbusarm();

To copy to clipboard, switch view to plain text mode 

But I would question why you are inheriting from Ui_modbusarm?
Wouldn't it be simpler to do it correct way:

class modbusarm:public QMainWindow
{
    Q_OBJECT
 
public:
    modbusarm()
        :
        ui( new Ui::modbusarm )
        {
            ui->setupUi( this );
 
            // more stuff here ...
            // more stuff here ...
            // more stuff here ...
        }
 
private:
    Ui::modbusarm* ui;
};

class modbusarm:public QMainWindow
{
    Q_OBJECT

public:
    modbusarm()
        :
        ui( new Ui::modbusarm )
        {
            ui->setupUi( this );

            // more stuff here ...
            // more stuff here ...
            // more stuff here ...
        }

private:
    Ui::modbusarm* ui;
};
