imread return a Mat object with no methods

I'm trying to change some code from openCV to openCV2 in windows using a Cmake/Mingw compiled openCV248 (on Eclipse). My normal openCV code works fine using cvLoadImage and cvShowImage. But when I try to use imread and imshow I get a Mat from the imread that has no methods and an error from eclipse that tells me that imshow has invalid arguments...

Here is an example code:

#include <iostream>
#include "opencv2/core/core.hpp"
#include "opencv2/highgui/highgui.hpp"

using namespace std;
using namespace cv;


int main( int argc, char** argv )
{
    if( argc != 2)
    {
        cout <<" Usage: display_image ImageToLoadAndDisplay" << endl;
        return -1;
    }

    Mat image = imread("pic.jpg",0);   

    namedWindow( "window", CV_WINDOW_AUTOSIZE );

    imshow("window", image);
    waitKey(10);

    resizeWindow("window", 400, 400);

    waitKey(0);                                         
    return 0;
}

Any help ?
