is there something wrong with the local environment?

code:

    if (retval) return -1;

    Mat pano;
    Stitcher stitcher = Stitcher::createDefault(TRUE);
    Stitcher::Status status = stitcher.stitch(imgs, pano);

    if (status != Stitcher::OK)
    {
        cout << "Can't stitch images, error code = " << status << endl;
        return -1;
    }

    imwrite(result_name, pano);
    return 0;
