Embedding a shared library in a QML File

Reinier R. Gonzalez

I'm trying to use a shared library (created by me) in a QML file. The project its about a game with virtual players. Each 'virtual' player it's just a shared library that exposes a name and a playing function. All seems to be good until the compiling phase when the next error arises:
C:\Qt\Qt5.3.0\5.3\mingw482_32\include\QtCore\qmetatype.h:1297: error: 'QObject' is an inaccessible base of 'Player'
enum { Value = sizeof(checkType(static_cast<T*>(0))) == sizeof(yes_type) };
^

this is the .pro file:
TEMPLATE = app
QT += qml quick widgets
SOURCES += main.cpp
RESOURCES += qml.qrc
resources.qrc
QML_IMPORT_PATH =
include(deployment.pri)
OTHER_FILES +=
unix|win32: LIBS += -L$$PWD/dlls/ -lplayer
INCLUDEPATH += $$PWD/dlls
DEPENDPATH += $$PWD/dlls

the player.h file:
#ifndef PLAYER_H
#define PLAYER_H

#include "player_global.h"
#include <QObject>
#include <QString>

class PLAYERSHARED_EXPORT Player : QObject
{
Q_OBJECT
Q_PROPERTY(QString name READ getName WRITE setName NOTIFY nameChanged)
QString name;
Q_PROPERTY(QString id READ getId WRITE setId NOTIFY idChanged)
QString id;

public:
Player(QString name);
const QString getName();
void setName(const QString name);
const QString getId();
void setId(const QString id);

signals:
void nameChanged();
void idChanged();
};

#endif // PLAYER_H

the player.cpp file:
#include "player.h"

Player::Player(QString name = "")
{
this->name = name;
}

const QString Player::getName()
{
return this->name;
}

void Player::setName(const QString name)
{
this->name = name;
}

const QString Player::getId()
{
return this->id;
}

void Player::setId(const QString id)
{
this->id = id;
}

the main.cpp:
#include <QApplication>
#include <QQmlApplicationEngine>
#include <QtQml>

#include "player.h"

int main(int argc, char *argv[])
{
QApplication app(argc, argv);

qmlRegisterType<Player>("cu.uci.fac5.player", 1, 0, "Player");

QQmlApplicationEngine engine;
engine.load(QUrl(QStringLiteral("qrc:///main.qml")));

return app.exec();

}

Hi @Reinier-R.-Gonzalez,

The class should be declared as:

class PLAYERSHARED_EXPORT Player : public QObject //Note the public keyword
