New to QT

[intek]

I'm just trying to run the program, but I get this errror with respect to the class:

:-1: error: collect2: ld returned 1 exit status

I only get this error when I do T : public QObject
(Adding QObject)

Help would be appreciated! Thanks

#ifndef T_H
#define T_H
 
#include <QString>
#include <QObject>
 
class T : public QObject
{
    public:
    T() {}
};
 
#endif // T_H

#ifndef T_H
#define T_H

#include <QString>
#include <QObject>

class T : public QObject
{
    public:
    T() {}
};

#endif // T_H
