I hope this helps

Nothing suspicious is here.
You did re-generate ui_blackmainwindow.h with Qt5.2.1, right?
Could you show please part of ui_blackmainwindow.h that is related to QUuid.

[apreddy]

yeah i did regenerate the ui_blackmainwindow.h
I cleaned the project and then ran qmake and then built the project
@#ifndef UI_BLACKMAINWINDOW_H
#define UI_BLACKMAINWINDOW_H

#include <QtCore/QVariant>
#include <QtWidgets/QAction>
#include <QtWidgets/QApplication>
#include <QtWidgets/QButtonGroup>
#include <QtWidgets/QDockWidget>
#include <QtWidgets/QFrame>
#include <QtWidgets/QHBoxLayout>
#include <QtWidgets/QHeaderView>
#include <QtWidgets/QMainWindow>
#include <QtWidgets/QMenuBar>
#include <QtWidgets/QPushButton>
#include <QtWidgets/QSpacerItem>
#include <QtWidgets/QStackedWidget>
#include <QtWidgets/QVBoxLayout>
#include <QtWidgets/QWidget>
#include "blackframewidget.h"
#include "blackinfowidget.h"
#include "blacksettingswidget.h"
#include "blackshotsettingswidget.h"
#include "blackshotwidget.h"
#include "blacksourcewidget.h"
#include "blackxmlsettingswidget.h"
#include "blackxmlwidget.h"
@

actually the quuid stuff resides in another source file which is then added to the header here is an instance.
@void blackSettingsWidget::saveSettings()
{
QUuid blackFrameId;
QString blackFrameName = blackFrameProfileNameLineEdit->text();
int blackFrameIndex = blackFrameProfileComboBox->findText(blackFrameName);

if (blackFrameIndex == -1)
{
    blackFrameId = QUuid::createUuid();
    blackFrameProfileComboBox->addItem(blackFrameName, blackFrameId.toString());
}
else
{
    blackFrameId = QUuid(blackFrameProfileComboBox->itemData(blackFrameIndex).toString());
}

//TO DO
verifyBlackFrameSettings();

saveBlackFrameSettings(blackFrameId, blackFrameName);
blackFrameProfileComboBox->setCurrentIndex(blackFrameProfileComboBox->findText(blackFrameName));

setupBlackFrameSettings(blackFrameId);

returnBlackSettingsToNormal();

emit reloadBlackFrameProfilesSignal();

}

void blackSettingsWidget::saveBlackFrameSettings(QUuid id, QString name)
{
blackFrameParameters* parametersB= new blackFrameParameters();
blackFrameSettings* blackFrame = new blackFrameSettings(parametersB);

blackFrame->setId(id);
blackFrame->setName(name);
blackFrame->setDetectBlackOption(automaticallyDetectBlackFramesCheckBox->checkState());
blackFrame->setDetectBlackLevel(detectBlackLevelLineEdit->text().toUInt());
blackFrame->setDetectBlackFrameMinimum(detectBlackMimimumFramesLineEdit->text().toUInt());
blackFrame->setDetectBlackMethod(detectBlackMethodComboBox->currentIndex());

int setB = dataBasePointer->setSettingInDataBase(parametersB, dataBase::BLACKFRAME);
if (setB)
{
    QMessageBox::critical(this, tr("Error"), tr("Data Base Error.\n\n%1").arg(dataBasePointer->warningErrorMessage));

    return;
}

You do not use extern "C" anywhere, right?

I created a small project with QUuid and I was not able to reproduce the problem.
I build it in Qt 4.8.5, 5.2.1, and 5.3.0

I guess you will need to comment out the suspicious lines one by one and try to find what particular line cause this error.

[apreddy]

i tried doing that .. but unfortunately i had like a lot of errors. that too in the in the qt header files ...so i suspect what i am doing is wrong.. another thing to mention here is that all my source files when i individually compile compile well but when i compile the entire project that's when i get into trouble.

[hskoglund]

Hmm just a guess, mabe you quuid stuff needs a qglobal.h, perhaps try
#include <qglobal.h>
just before
#include <ui_blackmainwindow.h>
in your blackmainwindow.h (or the .h file where the quuid stuff goes)

[apreddy]

Hi hskoglund,

I tried including q global but that has not improved the situation.

[apreddy]

Hi There,

Dose anyone have any more suggestions??

[andreyc]

Have you tried to build the project on other OS (Linux, MacOS X) ?

[apreddy]

I tried building it in Mac OS X and it works fine, and i have not tried bulding it in linux yet.

[andreyc]

Do you use correct compiler to build on windows?
Check in the settings what compiler version is selected to Qt 5.

[apreddy]

I a using MinGW4.8 32 bit compile which came along the qt .

[andreyc]

You don't have other versions of Qt and compilers, right?

[apreddy]

nope i uninstalled the previous versons which i had previously installed..

[andreyc]

What if

create a simple Qt project

in the header of MainWindow #include <QUuid>

add QUuid variable to MainWindow

try to compile

Does it generate the error?
