Undefined reference

Hi. I've got a problem. When I tried to compile the program, there appear error:
undefined reference to 'abcziom()' in maker.cpp. Here are those two files:
Maker.cpp

Code:

---

#include <QtGui>
 
 #include "maker.h"
 
 MainWindow::MainWindow(QMainWindow *parent)
     : QMainWindow(parent)
 {
     ui.setupUi(this);
     }
void MainWindow::abcziom()
 
 {
 
 
 }

---

Maker.h

Code:

---

#ifndef MAKER_H
 #define MAKER_H
 
 #include "ui_maker.h"
 
 
 class MainWindow : public QMainWindow, public Ui::MainWindow
 {
     Q_OBJECT
 
 public:
     MainWindow(QMainWindow *parent = 0);
 
 private slots:
 
    void abcziom();
 
 private:
 
     Ui::MainWindow ui;
 };
 
 #endif

---

Main.cpp, and ui_maker.h which I won't post, becauce is not problematic relationship. I really don't know what is this error about. Regards

Are both files (Maker.h and Maker.cpp) listed in .pro?

yes, they are

Add

Code:

---

#endif // MAKER_H

---

at the end of maker.h.

Heh, you're right. I managed to miss it, sorry. :)

Edit: Salazaar, could you show us your .pro file?

Sure.

Code:

It should be:

Code:

---

HEADERS += maker.h
FORMS   += maker.ui about.ui

---

This way qmake will generate ui_*.h file automatically every time you change the .ui file.

This was created by qmake. And I was trying to compile other applications this qmake system and it was ok

You should create project files with qmake before you start compilation, not after that. Then only update the file manually.

Sure I create project file before compiling, that's the procedure.

If you did, you wouldn't end up with ui_*.h files in it as these are created by uic during compilation. Unless of course you added them manually.

I've solved the problem (I don't know exactly how) but I still don't understand what was the problem about. I've got all my files and run qmake-project
