Need help making plugin

I'm trying to build a plugin, but make produces an error which I don't know what to do...

Following the directions from the book "C++ GUI Programming with Qt4"
I have 2 parallel directories: clientNotebook which has the .ui part (compiled without errors) and clientNotebookPlugin dir.

Problem is when I try to make the plugin, i get the following error:

clientNotebookPlugin.cpp: In member function ‘virtual QWidget* ClientNotebookPlugin::createWidget(QWidget*)â€⠄¢:
clientNotebookPlugin.cpp:48: error: expected type-specifier before ‘ClientNotebook’
clientNotebookPlugin.cpp:48: error: cannot convert ‘int*’ to ‘QWidget*’ in return
clientNotebookPlugin.cpp:48: error: expected ‘;’ before ‘ClientNotebook’
clientNotebookPlugin.cpp:48: error: ‘ClientNotebook’ was not declared in this scope
make: *** [clientNotebookPlugin.o] Error 1

This is (I think is relevant) source code in the plugin directory...

// The plugin .pro file:

TEMPLATE = lib
CONFIG += designer plugin release

HEADERS += ../clientNotebook/clientNotebook.h\
clientNotebookPlugin.h
SOURCES += ../clientNotebook/clientNotebook.cpp\
clientNotebookPlugin.cpp

DESTDIR = /usr/local/Qt4.3/plugins/designer
// eof

// The plugin cpp file:

#include <QtPlugin>

#include "./clientNotebookPlugin.h"

ClientNotebookPlugin::ClientNotebookPlugin(QObject *parent)
: QObject (parent)
{
}

.... name() includeFile() group() etc...

// This is the problem function...

QWidget *ClientNotebookPlugin::createWidget(QWidget *parent)
{
return new ClientNotebook(parent);
}

Q_EXPORT_PLUGIN2(clientNotebookPlugin, ClientNotebookPlugin)

// eof

// plugin.h file:
#ifndef CLIENTNOTEBOOKPLUGIN_H
#define CLIENTNOTEBOOKPLUGIN_H

#include <QDesignerCustomWidgetInterface>


class ClientNotebookPlugin : public QObject, public QDesignerCustomWidgetInterface
{
Q_OBJECT
Q_INTERFACES(QDesignerCustomWidgetInterface)

public:
ClientNotebookPlugin(QObject *parent = 0);
QString name() const;
QString includeFile() const;
QString group() const;
QIcon icon() const;
QString toolTip() const;
QString whatsThis() const;
bool isContainer() const;
QWidget *createWidget(QWidget *parent);
};

#endif

Try including "clientNotebook.h" in clientNotebookPlugin.cpp.

Now that I've inserted the plugin into a form, it doesn't compile:

In file included from mainmenu.h:19,
from main.cpp:16:
ui_mainmenu.h:36:34: error: clientNotebookPlugin.h: No such file or directory
In file included from mainmenu.h:20,
from main.cpp:16:
clientNotebookPlugin/clientNotebookPlugin.h:4:42: error: QDesignerCustomWidgetInterface: No such file or directory

Why is ui_mainmenu.h not resolving ?
Doesn't Qt look in the plugin dir for it ?
Do I need to set something in .pro file ?

Does ClientNotebookPlugin::includeFile() return "clientNotebookPlugin.h"? If so, make it return "clientNotebook.h" (or whatever is the correct file name).

Try adding "CONFIG += designer" to the .pro file (and re-generating the vs project).

YES ! ok, fixed, rebuilt plugin, cleaned project, rebuilt...but now:

In file included from mainmenu.h:19,
from main.cpp:8:
ui_mainmenu.h:36:28: error: clientNotebook.h: No such file or directory

No difference.

The plugin is just for using clientNotebook in designer. You still need to include clientNotebook to you project.

Thanks again, that should have been obvious to me.
Now I'm receiving yet ANOTHER undefined reference...

mainmenu.o: In function `Ui_MainMenu::setupUi(QMainWindow*)':
mainmenu.cpp:(.text._ZN11Ui_MainMenu7setupUiEP11QM ainWindow[Ui_MainMenu::setupUi(QMainWindow*)]+0x2094): undefined reference to `ClientNotebook::ClientNotebook(QWidget*)'
mainmenu.cpp:(.text._ZN11Ui_MainMenu7setupUiEP11QM ainWindow[Ui_MainMenu::setupUi(QMainWindow*)]+0x296d): undefined reference to `ClientNotebook::ClientNotebook(QWidget*)'
collect2: ld returned 1 exit status

Sorry, I've spent hours over this but I can't work out why. I wish I had more knowledge :-(

I tried placing the cpp and .o files in the same directory but it didn''t help.

Did you add clientNotebook.h and clientNotebook.cpp to the application's .pro file?

ok, added them, new error message:

clientNotebook.o: In function `ClientNotebook::ClientNotebook(QWidget*)':
clientNotebook.cpp:(.text+0x31): undefined reference to `vtable for ClientNotebook'
clientNotebook.cpp:(.text+0x38): undefined reference to `vtable for ClientNotebook'
clientNotebook.o: In function `ClientNotebook::ClientNotebook(QWidget*)':
clientNotebook.cpp:(.text+0xb1): undefined reference to `vtable for ClientNotebook'
clientNotebook.cpp:(.text+0xb8): undefined reference to `vtable for ClientNotebook'

Am using 2
clientNotebook widgets in mainMenu, hence error message twice.

Did you remember to re-run qmake or did you just add the file through an IDE or so?

That was it !!
I mistakenly put the header file listed in SOURCES instead of HEADERS...

SOURCES = main.cpp \
mainmenu.cpp \
clientNotebook/clientNotebook.cpp \
clientNotebook/clientNotebook.h

Thank you very much. :-)
