C++ Octave in QtCreator (windows) - c++

Question

I am trying to use Octave with Qt creator on Windows but I don't no why i can't succeed to link this library on this OS. I already tried on Ubuntu and everything works so i am a little bit lost...
I have octave3.6.4 (gcc 4.6.2) and i use the compiler gcc4.6.2 with Qt Creator.
my .pro file:
#-------------------------------------------------

# Project created by QtCreator 2015-01-26T11:35:00
#
#-------------------------------------------------
QT += core gui
greaterThan(QT_MAJOR_VERSION, 4): QT += widgets
TARGET = untitled
TEMPLATE = app
SOURCES += main.cpp\
mainwindow.cpp
HEADERS += mainwindow.h
FORMS += mainwindow.ui
LIBS += -L$$PWD/../../../../Octave/Octave3.6.4_gcc4.6.2/lib/octave/3.6.4/ -loctave -loctinterp -lcruft
INCLUDEPATH += $$PWD/../../../../Octave/Octave3.6.4_gcc4.6.2/include

PRE_TARGETDEPS += $$PWD/../../../../Octave/Octave3.6.4_gcc4.6.2/lib/octave/3.6.4/liboctinterp.dll.a
my .h file:
#ifndef MAINWINDOW_H
#define MAINWINDOW_H
#include <QMainWindow>
#include <octave-3.6.4/octave/oct.h>
#include <octave-3.6.4/octave/octave.h>
#include <octave-3.6.4/octave/parse.h>
#include <octave-3.6.4/octave/toplev.h>
namespace Ui {
class MainWindow;
}
class MainWindow : public QMainWindow
{
Q_OBJECT
public:
explicit MainWindow(QWidget *parent = 0);
~MainWindow();
private:
Ui::MainWindow *ui;
};
#endif // MAINWINDOW_H
And i have many link errors such as C2144 syntax error ...
