Plugin verification data mismatch error on my plugin load

Abin

yes, it has

QT += widgets
QT += network
QT += sql

But when I run from the Qt Creator it should be fine right? My plugin .pro file is

@TEMPLATE = lib
CONFIG += plugin
QT += widgets
QT += network
QT += sql
INCLUDEPATH += ../..
HEADERS = serverplugin.h
server.h
serverdbmanager.h
serverfunctionthread.h
commondefenitions.h
SOURCES = serverplugin.cpp
server.cpp
serverdbmanager.cpp
serverfunctionthread.cpp
TARGET = $$qtLibraryTarget(serverplugin)
DESTDIR = ../plugins

OTHER_FILES +=
serverplugin.json

Did you check that you have all the needed Qt libraries deployed on your target ?

Abin

I did not get it... It would be helpful if you could explain a bit more... When I run it from Qt Creator do I have to worry about it? I should check it only while creating my executable package.. correct?

SGaist

If I understood you correctly, it only fails on android, right ?

Abin

No, when the below lines are executed the cases in windows and android ill explain

@bool pluginLoaded = pluginLoader.isLoaded();
QObject *plugin = pluginLoader.instance();
if (plugin)
{
m_pServerInterface = qobject_cast<ServerInterface *>(plugin);
if (NULL != m_pServerInterface)
{
qDebug() << Q_FUNC_INFO << "plugin loaded successfully";
}
else
{
qDebug() << Q_FUNC_INFO <<
"plugin object casted to "
"ServerInterface is Null";
}
}@

win:
pluginLoaded is false
*QObject plugin is not null and @qDebug() << Q_FUNC_INFO << "plugin loaded successfully";@ is executed
so able to call plugin functions

Android:
pluginLoaded is false
*QObject plugin is null
so not able to call plugin functions

SGaist

Can you post the plugin header file ?

@#ifndef SERVERPLUGIN_H
#define SERVERPLUGIN_H

#include <QObject>
#include <QtPlugin>
#include "acepos/aceclient/serverinterface.h"

public:

private slots:

Hi
Can you tell us how you solved this problem?

Abin

@LeaA
I didn't solve it.

@Abin

I solved it..
check the Q_OBJECT macro and the inheritance from QObject.
