FreeImage: why does it not work with cairo?

Here is the code:

    bool bLoaded = false;
    FreeImage_Initialise();
    FIBITMAP* img = FreeImage_Load(FIF_PNG, "imageSave.png", 0);
    FreeImage_Unload(img);
    FreeImage_DeInitialise();


    int  w, h;
    //cr = cairo_create(image);
    cairo_surface_t *image = cairo_image_surface_create_from_png("/root/test1/FreeImage/imageSave.png");
    w = cairo_image_surface_get_width(image);
    h = cairo_image_surface_get_height(image);
    cout << "width " << w << " height " << h;

    cairo_surface_write_to_png(image, "image2.png");
    cairo_surface_destroy(image);

When I use FreeImage, the output of width and heigt is always 0, but when I comment this 4 line, the cairo works

    FreeImage_Initialise();
    FIBITMAP* img = FreeImage_Load(FIF_PNG, "imageSave.png", 0);
    FreeImage_Unload(img);
    FreeImage_DeInitialise();

How can I use this both library? Please help!
