Issue with QObject::connect

[fish_sticks]

Sorry.Here's my test.h file

#ifndef WIDGET_H
#define WIDGET_H
#include <QWidget>
 
using namespace std;
namespace Ui {
			class calc;
		}
 
class calc : public QWidget {
		Q_OBJECT
	public:
		calc(QWidget *parent = 0);
		~calc();
 
 
	protected:
 
	private:
		Ui::calc *ui;
 
	private slots:
 
	public slots:
		int appendone();
	};
#endif // WIDGET_H

#ifndef WIDGET_H
#define WIDGET_H
#include <QWidget>

using namespace std;
namespace Ui {
			class calc;
		}

class calc : public QWidget {
		Q_OBJECT
	public:
		calc(QWidget *parent = 0);
		~calc();
		

	protected:

	private:
		Ui::calc *ui;

	private slots:
		
	public slots:
		int appendone();
	};
#endif // WIDGET_H

To copy to clipboard, switch view to plain text mode 

I created an object for calc in my C++ file

calc c;

calc c;

To copy to clipboard, switch view to plain text mode 

Now I'm getting the following error

/home/anil/Tests/Qt/test/test.cpp:10: undefined reference to `calc::calc(QWidget*)'
/home/anil/Tests/Qt/test/test.cpp:10: undefined reference to `calc::~calc()'

make: *** [test] Error 1

You're missing a body for your constructor and your destructor. Did you implement them?
