Unsolved Undefined reference to vtable
-
Hello,
I added a form named "Suchen" and declared it in the suchen.h & suchen.cpp files.
During the compiling I have become a failure which I couldnt understand.
I added the "suchen.h" and suchen.cpp files. Do someone have an idea ?Thanks,
the header file :
#ifndef SUCHEN_H #define SUCHEN_H #include <QtSql> #include <QtGui> #include <QDialog> namespace Ui { class Suchen; } class Suchen : public QDialog { Q_OBJECT public: explicit Suchen(QWidget *parent = 0); ~Suchen(); public: //void suchenliste(); bool dbVerbinden(); public: QString sqlAbfrage; QString suchen1; private slots: void on_SucheStart_clicked(); void on_SucheBeenden_clicked(); private: Ui::Suchen *ui; //steht die Verbindung zur Datenbank? bool dbVerbunden; //für die Datenbank QSqlDatabase datenbank; }; #endif // SUCHEN_H
the cpp file :
#include "suchen.h" #include "ui_suchen.h" //#include "suchenliste.h" #include <QtSql> #include <QTableView> #include <QMessageBox> #include <QInputDialog> //der Konstruktor //er verbindet das Formular mit der Oberfläche und stellt die Verbindungen her Suchen::Suchen(QWidget *parent) : QDialog(parent), ui(new Ui::Suchen) { ui->setupUi(this); //dbVerbunden = dbVerbinden(); } Suchen::~Suchen() { delete ui; }

@cprogcoder said in Undefined reference to vtable:
private slots:
void on_SucheStart_clicked();
void on_SucheBeenden_clicked();Hi @cprogcoder
The cause of your problem is that you did not add definition of your slots on your cpp files
private slots: void on_SucheStart_clicked(); void on_SucheBeenden_clicked();
this should solve the problem:
void Suchen::on_SucheStart_clicked() { } void Suchen::on_SucheBeenden_clicked() { }
I hope this can help you !

Hi
Clean the build folder (delete it)
run qmake
and rebuild all and it should work.@mostefa
