How to convert function from visual studio C++ to QT c++ ?

Hi Experts,

I have this function:
Vector Vector::operator *(Matrix &m)      // return MatrixMulVector(this, m)
{    
    return (m * (*this));
}

where Vector:

        Vector()                        { Set(0, 0, 0); }
      Vector(float _x, float _y, float _z)      { Set(_x, _y, _z); }
        Vector(Vector &v)                  { Set(v.x, v.y, v.z); }

and Matrix:

Matrix()                                                { memset(p,0,sizeof(float)*9); }                              // nullify matrix
      Matrix(      float xx, float xy, float xz,
                  float yx, float yy, float yz,
                  float zx, float zy, float zz)      { Set(xx, xy, xz,  yx, yy, yz,  zx, zy, zz); }            // construct matrix from 9 floats
        Matrix(float ax, float ay, float az)      { SetAng(ax, ay, az); }                                          // construct matrix form 3 angles
      Matrix(Matrix &m)                                    { memcpy(p, m.p, sizeof(float)*9); }

My problem is that I can't compile it in QT 4.7 for Linux. However, it works without any problem in Visual Studio.

In QT I get this error:

no matching function for call to 'Vector::Vector(Vector)'
candidates are: Vector::Vector(Vector&)

Can someone tell me what should I change to create the equivalent of this function in QT ?

Thanks,
Peter

Try to change the vector's copy constructor to

        Vector(const Vector &v)  { Set(v.x, v.y, v.z); }  // notice 'const'
