Minimal QObject example doesn't compile !

idlefrog

Why does this minimal example not compile?
I get the dreaded 'undefined reference to vtable' error. :(

Header:

class MyObject: public QObject
{
    Q_OBJECT

public:
    MyObject();
    virtual ~MyObject();
};

Definition:

MyObject::MyObject(){}
MyObject::~MyObject(){}

My .pro file is:

QT += testlib
QT += gui widgets

CONFIG += qt console warn_on depend_includepath testcase
CONFIG -= app_bundle

TEMPLATE = app

SOURCES +=  \
    MyObject.cpp \
    tst_obj.cpp

I'm sure you don't need to have a slot/signal if you inherit from QObject. Is something very wrong with the .pro file?!

Although I don't think it's relevant, here's the test file:

#include <QtTest>
#include "MyObject.h"

class TestMyObject : public QObject
{
    Q_OBJECT
public:
    TestMyObject();
    ~TestMyObject();

private slots:
    void test_createMyObject();
};

TestMyObject::TestMyObject(){}
TestMyObject::~TestMyObject(){}

void TestMyObject::test_createMyObject()
{    
    MyObject myObject;
}
QTEST_APPLESS_MAIN(TestMyObject)
#include "tst_obj.moc"

You forgot to add the header to HEADERS

Yes...that's it. And I thought I was doing something wrong in the class somewhere!
Many thanks!!!
