strange error in compilation

[danadam]

but it is still giving same output.

Really? Is "qmenubar.h:29: error: expected initializer before 'QtGuiModule'" still there? Well, in that case I have no more ideas what the solution could be.

As far as the second error is concerned:

va.cpp: In member function 'virtual void vA1::initGui()':
va.cpp:98: error: no matching function for call to 'QAction::QAction(QIcon, const char [4], vA1* const)'
/usr/local/Trolltech/Qt-4.1.2//include/QtGui/qaction.h:173: note: candidates are: QAction::QAction(const QAction&)
...

...

It seems that in line 98 of va.cpp you are calling QAction constructor, but with wrong parameters. There is no QAction(QIcon, const char [4], vA1* const) constructor (at least according to compiler ) and it gives you a list of similar ones, which exist.

about QAction constructor error i had checked arguments do match and constructor also exists but it is giving me this error.
Here is snap of that code

void vA1::initGui()
{
 
  // Create the action for tool
  mQActionPointer = new QAction(QIcon(":/va/va.png"),"vA1", this);
  // Set the what's this text

void vA1::initGui()
{

  // Create the action for tool
  mQActionPointer = new QAction(QIcon(":/va/va.png"),"vA1", this);
  // Set the what's this text

At http://doc.trolltech.com/4.1/qaction.html i found this

Public Functions
 
      QAction ( QObject * parent )
 
      QAction ( const QString & text, QObject * parent )
 
      [COLOR="Blue"]QAction ( const QIcon & icon, const QString & text, QObject * parent )
    [/COLOR]
      ~QAction ()

    [/COLOR]
      ~QAction ()

About my other issue i request experienced users to guide me in this.

i found that i hadn't included QObject class which i did so up mentioned error went away.

About second issue of

usr/local/Trolltech/Qt-4.1.2//include/QtGui/qmenubar.h:29: error: expected initializer before 'QtGuiModule'

usr/local/Trolltech/Qt-4.1.2//include/QtGui/qmenubar.h:29: error: expected initializer before 'QtGuiModule'

i changed my header file as

#define vA_H
 
//QT4 includes
#include <QObject>
 
//QGIS includes
#include <qgisapp.h>
#include <qgsmaptool.h>

#include<qgspoint.h>
#include "../qgisplugin.h"
 
#include "vARubberBand.h"
;
//forward declarations
 
class QToolBar;// LINE NO 54
 
/**

i think you will be noticing the semicolon after line

#include "vARubberBand.h"

#include "vARubberBand.h"

, this is what i did a sort of hit and trial to compile it. It did. If i didn't put this semicolon it give the message

va.cpp line 54: multiple types in one declaration

va.cpp line 54: multiple types in one declaration

i donot have reasoning for such behaviour. Kindly anyone put some light on this issue. All comments, suggestion and other solutions are welcome

Just add the missing semicolon after your class definition.

thanks jacek!. I couldn't even imagine that this isssue was there.
