Problem with qmap.h from QT5.6.3 for MSVC2013 (64bit)

[Domenico]

My app builds fine with QT5.6.3 using msvc2013 (64bit).

Get this error:

PLEASE HELP ME!!! Do you know what the problem is? can I solve?

[Domenico]

I solved!

the problem was of the macro:

#ifdef _DEBUG
#define new DEBUG_NEW
#endif

this macro only works if compiled under the Visual Studio development environment in DEBUG mode.
just change the macro in:

#ifdef QT_DEBUG
#endif

and add in .pro file:

CONFIG(debug, release|debug):DEFINES += QT_DEBUG

and Hola works with this macro under the Qt Creator development environment in DEBUG mode

[SGaist]

Hi and welcome to devnet,

How are you using QMap ?

[Domenico]

@SGaist Trank you,
excuse my ignorance in what sense how am I using QMap?

if I understand correctly I'm using it in various ways in various sources:

1. QMap<int,QString> ....
2. QMap<int,int> ....
3. QMap<int,RoleData> ....

RoleData is a class where they contain a series of parameters to be assigned one of the complex one there is also the parameter of type QVector<QString>

if that was what he wanted to know how I'm using QMap, then what problem can it be?

[Christian Ehrlicher]

I would try to create a simple main which just instantiates a QMap instance to see if this works. I'm not really sure if Qt5 64bit with msvc2013 ever worked but it's rather old so I might be wrong.

[Domenico]

@Christian-Ehrlicher

I tried with various versions of Qt, the problem persists !! I do not understand what you're from ... do you think it's badly instanced?

does anyone know the solution to this problem?

[SGaist]

Do you mean that you have the same problem with something like:

#include <QMap>
#include <QString>
#include <QtDebug>

int main(int /*argc*/, char **/*argv*/)
{
    QMap<int, QString> map;
    map[1] = QStringLiteral("test");
    qDebug() << map;
    return 0;
}

[edit: Fixed includes SGaist]

[kshegunov]

Did you include QString and the QVariant headers? Please provide the snippet which induces this error.

[Domenico]

@SGaist

Sorry for the delay.

I tried with codes from as you indicated below QT5.6 with MSVC2013 64bit and it works.

the error that brings me back to my code gives it to me when I compile in Debug mode while in Release mode it works, only I need it in Debug mode to do analysis in Debbugers.

I do not understand why it gives me error in Debug mode and not in Release mode. in your opinion what can be wrong with Debug about QMap ??

[aha_1980]

@Domenico Check the includes @kshegunov mentioned. Most likely that's the problem.

[Domenico]

@kshegunov @aha_1980

Thank you so much for the solution !!

I tried as you said, including QString and QVariant in headers where it is using QMap .. the error persists .. :(

[J.Hilk]

@Domenico can you post the files /classes where you use QMap and the error occurs?

[Domenico]

I try to publish the sources, as it is too long. public part .h e .cpp where and how is using QMap, I hope it is understandable. if it is not, please let me know that I will try to publish more.

in the class .h

#ifndef ROLEADMINISTRATIONMODEL_H
#define ROLEADMINISTRATIONMODEL_H

#include <QMap>
#include <QString>
#include <QVariant>
#include <QList>

#include "ErrorTypeDefinition.h"
#include "RoleData.h"
#include "DBManager.h"

class RoleAdministrationModel
{
private:
RoleData m_currentRoleSelected;
QMap<int,RoleData> m_roleList;

RoleAdminErrorType deleteRole(RoleData roleData);
RoleAdminErrorType modifyRole(RoleData roleData);
RoleAdminErrorType newRole(RoleData roleData);

public:
RoleAdministrationModel();
QList<QString> getFuncList();
QList<RoleData> getRoleData();

void roleSelected(RoleData rolSel);
RoleAdminErrorType saveRole(RoleData role);

};

#endif // ROLEADMINISTRATIONMODEL_H

in the class .cpp

#include "RoleAdministrationModel.h"

RoleAdministrationModel::RoleAdministrationModel()
{
m_roleList.clear();
}

QList<QString> RoleAdministrationModel::getFuncList()
{
return DBManager::getInstance()->getFuncList();
}

QList<RoleData> RoleAdministrationModel::getRoleData()
{
QList<RoleData> roleList;
QList<RoleData>::iterator it;

m_roleList.clear();

roleList = DBManager::getInstance()->getRoleData();

for(it = roleList.begin(); it != roleList.end(); it++)
{
    m_roleList.insert((*it).getRoleId(),*it);
}

return roleList;

}

void RoleAdministrationModel::roleSelected(RoleData rolSel)
{
m_currentRoleSelected = rolSel;
}

RoleAdminErrorType RoleAdministrationModel::deleteRole(RoleData roleData)
{
...not use QMap...
}

RoleAdminErrorType RoleAdministrationModel::modifyRole(RoleData roleData)
{
...not use QMap...
}

RoleAdminErrorType RoleAdministrationModel::newRole(RoleData roleData)
{
...not use QMap...
}

RoleAdminErrorType RoleAdministrationModel::saveRole(RoleData role)
{
...not use QMap...
}

this is class of Roledata.h

#ifndef ROLEDATA_H
#define ROLEDATA_H

#include <QString>
#include <QVector>

#include "EnumTypeDefinition.h"

class RoleData
{
public:

bool isValid();
bool isFuncIsAssociatedToRole(QString funcName);

private:
int m_RoleId;
QString m_RoleName;
QVector<QString> m_FunctionalityNameList;
RoleOperationType m_Operation;
};

Roledata.cpp

#include "RoleData.h"

RoleData::RoleData()
{
m_RoleName = "";
m_Operation = R_INVALID_OPERATION;
m_FunctionalityNameList.clear();
m_RoleId = -1;
}

RoleData::RoleData(int roleId, QString roleName, RoleOperationType op)
{
m_RoleName = roleName;
m_Operation = op;
m_RoleId = roleId;
}

RoleData::RoleData(QString roleName)
{
m_RoleName = roleName;
m_Operation = R_INVALID_OPERATION;
m_RoleId = -1;
}

RoleData::RoleData(int roleId, QString roleName)
{
m_RoleId = roleId;
m_RoleName = roleName;
}

QString RoleData::getRoleName()
{
return m_RoleName;
}

RoleOperationType RoleData::getOperationType()
{
return m_Operation;
}

int RoleData::getRoleId()
{
return m_RoleId;
}

void RoleData::addFuncionality(QString name)
{
m_FunctionalityNameList.append(name);
}

QVector<QString> RoleData::getFuncionalityList()
{
return m_FunctionalityNameList;
}

bool RoleData::isValid()
{
return !(m_RoleName.isEmpty());
}

bool RoleData::isFuncIsAssociatedToRole(QString funcName)
{
bool result = false;

result = m_FunctionalityNameList.contains(funcName);

return result;

}

the error that brings me back into Debug mode:

while the other QMap I'm using (QMap <int, String> and QMap <int, int>) I do not publish it because it's too long, but I think the error comes more from code as indicated above, according to you if something wrong with code above? if everything is perfect I try to publish the codes that are using QMap <int, QString> and QMap <int, int>.

thank you very much for those who give me a solution !!!

[aha_1980]

@Domenico And what is in EnumTypeDefinition.h ?

[Domenico]

@aha_1980

you're right, sorry, the class of EnumTypeDefinition.h is

#ifndef ENUMTYPEDEFINITION_H
#define ENUMTYPEDEFINITION_H

typedef enum _UserAccountOperationType
{
UAC_NEW_USER = 0,
UAC_MODIFY_USER,
UAC_DELETE_USER,
UAC_INVALID_OPERATION

}UserAccountOperationType;

typedef enum _RoleOperationType
{
R_NEW_ROLE = 0,
R_MODIFY_ROLE,
R_DELETE_ROLE,
R_INVALID_OPERATION

}RoleOperationType;

typedef enum _ObjectSensitivity
{
OS_UNSENSIBLE,
OS_SENSIBLE

}ObjectSensitivity;

typedef enum _ObjectActDeact
{
OAD_ACTIVE,
OAD_DEACTIVE

}ObjectActDeact;

typedef enum _SystemStatus
{
SS_UNKNOWN,
SS_READY,
SS_DEFAULT,
SS_OFFLINE,
SS_ACTIVE,
SS_CONFIG,
SS_FAILURE,
SS_DEGRADED

}SystemStatus;

#endif // ENUMTYPEDEFINITION_H

what do you think of the codes above?

[J.Hilk]

The only place where you actually use QMap is here

QList<RoleData> RoleAdministrationModel::getRoleData()
{
QList<RoleData> roleList;
QList<RoleData>::iterator it;

m_roleList.clear();

roleList = DBManager::getInstance()->getRoleData();

for(it = roleList.begin(); it != roleList.end(); it++)
{
    m_roleList.insert((*it).getRoleId(),*it);
}

return roleList;
}

which doesn't seem quite right, I'm unsure.

Can you try it with a more simplified version?

QList<RoleData> RoleAdministrationModel::getRoleData()
{
QList<RoleData> roleList = DBManager::getInstance()->getRoleData();

m_roleList.clear();

for(const RoleData &data : roleList)
{
    m_roleList.insert(data.getRoleId(), data);
}

return roleList;
}

[Domenico]

I have done a deep study the problem of the error does not concern in the codes .. but the error comes from the macro of the _DEBUG in fact compile in RELEASE mode works while compiling in DEBUG mode gives me error as indicated above, then going to look at the macro:

#ifdef _DEBUG
#define new DEBUG_NEW
#endif

this macro of _DEBUG does not convince me the error I think it is connected to this macro .. someone can define a macro that can fill in the right way under Qt5.6 with MSVC2013 64bit without giving errors on qmap.h and qlist.h ??

Thanks again

[Domenico]

I solved!

the problem was of the macro:

#ifdef _DEBUG
#define new DEBUG_NEW
#endif

this macro only works if compiled under the Visual Studio development environment in DEBUG mode.
just change the macro in:

#ifdef QT_DEBUG
#endif

and add in .pro file:

CONFIG(debug, release|debug):DEFINES += QT_DEBUG

and Hola works with this macro under the Qt Creator development environment in DEBUG mode
