ActiveQt out-of-process server: signals are not working

Question

I have to use ActiveQt (qt 4.8.6 windows7). I have a problem with out-of-process server (.exe). It's registered successfully, it's responding to container's signals with its slots, but i can't make server emit signals (or to make container accept them).

pro file:

TARGET = object_mkpa
TEMPLATE = app
CONFIG += qt warn_off qaxserver
RC_FILE  = qaxserver.rc
DEF_FILE = qaxserver.def
SOURCES += src/object_mkpa.cpp \
    src/main.cpp
HEADERS += src/object_mkpa.h

header:

#include <QObject>
#include <QAxBindable>

class Object_mkpa : public QObject, public QAxBindable
{
    Q_OBJECT

    Q_CLASSINFO("RegisterObject", "yes")

public:
    Object_mkpa(QObject* parent = 0 );

public slots:
    ...
signals:
    ...
};

source:

#include "object_mkpa.h"
#include <QAxFactory>

Object_mkpa::Object_mkpa(QObject* parent) : QObject(parent) {  }

QAXFACTORY_DEFAULT(Object_mkpa,                              //widget class
                   "{69dfccf5-697f-497f-8aa9-d1ecfb64c1bf}", //class ID
                   "{e276cc69-3bf8-4932-b341-bdcb1045901b}", //interface ID
                   "{60b215f0-7f16-4f79-bac8-6b8d3cb14a00}", //event interface
                   "{110d3945-cfe7-4ae7-872c-02757e8dde91}", //type library ID
                   "{88dec6e0-4a5a-4c0b-bcdd-3f18dea9d86d}") //app ID
    ...

and main, which is actually not essential (does it even executes?..)

#include "object_mkpa.h"
#include <QApplication>

int main(int argc, char* argv[])
{
  QApplication app(argc, argv);
  return app.exec();
}

I've tested in-process server (dll) and signals work there, but it has another problem - it instantiates COM-object for every container that uses dll. I think that's how it's supposed to be (which is the opposite of what i do need), but if you know any hack - please tell me.

the difference with out-of-process is lack of main.cpp and slightly changed .pro file

TARGET = object_mkpa_dll
TEMPLATE = lib
CONFIG += qt warn_off dll qaxserver
RC_FILE  = qaxserver.rc
DEF_FILE = qaxserver.def
LIBS += -lQAxServerd
HEADERS += \
    object_mkpa_dll.h
SOURCES += \
    object_mkpa_dll.cpp

After building using qt creator native build steps i do use dumpcpp on .exe or .dll and copy generated files to client directory.

important part of .pro file:

QT       += core gui
greaterThan(QT_MAJOR_VERSION, 4): QT += widgets
TEMPLATE = app
CONFIG += qaxcontainer

Finally that is how i use it:

object_mkpaLib::Object_mkpa interface; //this is in class declaration

QObject::connect(&interface, SIGNAL(test(int)), SLOT(testTester(int)));
QObject::connect(this, SIGNAL(test(QString)), &interface, SLOT(test2(QString)));
