Q:

Can't emit signal in Android

I have this signal in my project;
void sendImage(cv::Mat &imgMat, QImage &imgQImage);

Project compiles on both Mingw and Visual Studio but when i try to build for Android, i get "error: no matching function for call to imageReader::sendImage(cv::Mat&, QImage)" error.
I tested my pro file on different project, try clean/run qmake/clean/rebuild, remove cv::Mat from signal but nothing worked.
What can be the problem?
Edit;
#ifndef READERMANAGERQMLINTERFACE_H
#define READERMANAGERQMLINTERFACE_H

#include <QObject>
#include <QDebug>

#include "readermanager.h"
class ReaderManagerQMLInterface : public QObject
{
    Q_OBJECT
public:
    explicit ReaderManagerQMLInterface(QObject *parent = 0);
    ~ReaderManagerQMLInterface();

    readerManager rManager;

private:

signals:
    void reqIm();

public slots:
    void sendImage(QImage &imgQImage);
};

#endif // READERMANAGERQMLINTERFACE_H

imageReader;
#ifndef IMAGEREADER_H
#define IMAGEREADER_H

#include <QObject>
#include <QImage>
#include <QDebug>
#include <QThread>
#include <QDir>
#include <QFile>

#include <opencv/cv.h>
class imageReader : public QObject
    {
        Q_OBJECT
    public:
        explicit imageReader(QObject *parent = 0);
        ~imageReader();
        imgHelpers imHelpers;

    signals:
        void sendImage(QImage &imgQImage);
    public slots:
        void requestImage();
        void setFrame(int frameID);
        void loadImage(QString fileName);
    }

I'm emitting signal like this;(in case my mat2Image function causes the problem, i tried both)
void imageReader::requestImage()
{
    images.at(currentImageID).copyTo(this->currentImage);
    processImage(currentImage);
    emit sendImage(imHelpers.mat2Image(this->currentImage) );
  //emit sendImage(QImage("d:/test.bmp"));
}

A:

I opened an issue in bugreports.qt.io and looks like problem is related to Visual Studio. You can find details in here.
Edit: When i say "problem is related visual studio" i mean "Visual Studio lead me in the wrong direction", my emit line should give compile error in the first place like gcc.
