Hi all.
Im developing a qt app to use on a wince device.
I have compiled the OpenSource version of Qt for winCE, and it is working.
My program compiles fine. However, if i have any slots defined in the header file, it throws the following linker error:
moc_updatedialog.obj : error LNK2019: unresolved external symbol "private: void __cdecl UpdateDialog::On_btnSubmitNE_pressed(void)" (?On_btnSubmitNE_pressed@UpdateDialog@@AAAXXZ) referenced in function "public: virtual int __cdecl UpdateDialog::qt_metacall(enum QMetaObject::Call,int,void * *)" (?qt_metacall@UpdateDialog@@UAAHW4Call@QMetaObject@@HPAPAX@Z)
this is the header file which compiles:
#ifndef UPDATEDIALOG_H
#define UPDATEDIALOG_H
#include <QDialog>
#include <QObject>
#include "ui_updatedialog.h"
class UpdateDialog : public QDialog
{
Q_OBJECT
public:
UpdateDialog(QWidget *parent = 0);
~UpdateDialog();
private:
Ui::UpdateDialogClass ui;
private slots:
//void On_tbxBatchIDUP_returnPressed();
//void On_tbxLocationNE_returnPressed();
//void On_tbxQtyPotsNE_returnPressed();
//void On_btnSubmitNE_pressed();
};
#endif // UPDATEDIALOG_Hhowever, this does nothing. i have linked to all qt libraries that i am using, and the QtDesigner/QtDesignerComponents, as i made the .ui files in QtDesigner.
here is the code that throws the errors:
#ifndef UPDATEDIALOG_H
#define UPDATEDIALOG_H
#include <QDialog>
#include <QObject>
#include "ui_updatedialog.h"
class UpdateDialog : public QDialog
{
Q_OBJECT
public:
UpdateDialog(QWidget *parent = 0);
~UpdateDialog();
private:
Ui::UpdateDialogClass ui;
private slots:
void On_tbxBatchIDUP_returnPressed();
void On_tbxLocationNE_returnPressed();
void On_tbxQtyPotsNE_returnPressed();
void On_btnSubmitNE_pressed();
};
#endif // UPDATEDIALOG_Hi assume the problem has something to do with the moc'ing process.
the qt version is 4.5.3
here is the VS build log:
