[Solved]No such file or directory error

[graham1941]

Sirs
I have recently upgraded my OS from Ubuntu 10.04 to Mint 15 and attempting to recompile my existing code.
I have a program that compiled before and now fails with a No such file or directory error.
My pro file looks like this:
@
TARGET = inputDialogue
TEMPLATE = lib
QT += widgets
DEFINES += INPUTDIALOGUE_LIBRARY

SOURCES += inputdialogue.cpp

HEADERS += inputdialogue.h
inputDialogue_global.h
@

inputdialog.h looks like this:
@
#ifndef INPUTDIALOGUE_H
#define INPUTDIALOGUE_H

#include "inputDialogue_global.h"
#include <QApplication>
#include <QtWidgets>
#include </usr/include/qt4/QtGui/QtGui>
#include </usr/include/qt4/QtGui/QMessageBox>
#include </usr/include/qt4/QtGui/QInputDialog>
//
enum SEVERITY { QUESTION, INFORMATION, WARNING, CRITICAL};

class INPUTDIALOGUESHARED_EXPORT InputDialogue {
public:
InputDialogue();

QString getError(void) { return errorMsg; }
void setError(QString txt) { errorMsg = txt; }

QString getLabelText(void) { return Label; }
void setLabelText(QString txt) { Label = txt; }

int getResponse(void) { return response; }
void setResponse(int res) { response = res; }

void test(int);

private:
QString Label;
QString errorMsg;
int response;
};

#endif // INPUTDIALOGUE_H
@

inputDialogue_global.h like this:

@
#ifndef INPUTDIALOGUE_GLOBAL_H
#define INPUTDIALOGUE_GLOBAL_H

#include <QtCore/qglobal.h>

#if defined(INPUTDIALOGUE_LIBRARY)

define INPUTDIALOGUESHARED_EXPORT Q_DECL_EXPORT

#else

define INPUTDIALOGUESHARED_EXPORT Q_DECL_IMPORT

#endif

#endif // INPUTDIALOGUE_GLOBAL_

@

inputdialogue.cpp like this:

@
#include "inputdialogue.h"

InputDialogue::InputDialogue()
{
}

//InputDialogue INPUTDIALOGUESHARED_EXPORT inputdialog;

void InputDialogue::test(int mode)
{
QString title;
QMessageBox msgBox;
int ret;

title = getLabelText();
errorMsg = getError();

setResponse(NULL);
msgBox.setText(title);
msgBox.setInformativeText(errorMsg);
switch (mode)
{
//case information:
case INFORMATION:
msgBox.setIcon(QMessageBox::Information);
msgBox.setStandardButtons(QMessageBox::Ok );
msgBox.setDefaultButton(QMessageBox::Ok);
ret = msgBox.exec();
setResponse(0);
break;

//case warning:
case WARNING:
msgBox.setIcon(QMessageBox::Warning);
msgBox.setStandardButtons(QMessageBox::Ok | QMessageBox::Cancel);
msgBox.setDefaultButton(QMessageBox::Ok);
switch (msgBox.exec())
{
case QMessageBox::Ok:
setResponse(0);
break;
case QMessageBox::Cancel:
setResponse(2);
break;
}
break;

//case critical:
case CRITICAL:
msgBox.setIcon(QMessageBox::Critical);
msgBox.setStandardButtons(QMessageBox::Ok );
msgBox.setDefaultButton(QMessageBox::Ok);
ret = msgBox.exec();
setResponse(0);
break;

//case question:
case QUESTION:
msgBox.setIcon(QMessageBox::Question);
msgBox.setStandardButtons(QMessageBox::Yes | QMessageBox::No | QMessageBox::Cancel);
msgBox.setDefaultButton(QMessageBox::Ok);
switch (msgBox.exec())
{
case QMessageBox::Ok:
setResponse(0);
break;
case QMessageBox::No:
setResponse(1);
break;
case QMessageBox::Cancel:
setResponse(2);
break;
}
break;
}
}

Any information would be greatfully received.
Thank you in anticipation.

Hi and welcome to devnet,

You have to give more information about your error. "No such file or directory" alone doesn't really help, what can't it find ? Which version of Qt are you using ?

[graham1941]

Hi SGaist
Thank you for your response.
On compiling I get the following error message:
@
/usr/include/qt4/QtGui/qinputcontext.h:64: error: QtGui/qaction.h: No such file or directory
@
Both these header files do exist in the includes directory.
I am using Qt4.
I note from other answers to this question that QT += widget should be included in the pro file, which I have done.
I originally created this program in February on ubuntu 10.04 without a problem.
Is there something I'm missing here?

[SGaist]

It should be included for Qt 5 project and should give you an error currently if you are using Qt 4.

So are you sure you are using the correct qmake ?

[graham1941]

It would appear that I am using qt5.
I have decided to start from scratch with an empty project and copy/paste chunks of code and recompile. Probably the easest way.
Thank you for all your help.

You're welcome,

If you have it working now, please update the thread title prepending [solved] so other forum users may know a solution has been found :)

@Mijaz it's written right here:
