Trying to use face recognition, the facerecognizer

So I copied from http://docs.opencv.org/trunk/modules/contrib/doc/facerec/facerec_api.html

 // Let's say we want to keep 10 Eigenfaces and have a threshold value of 10.0
 int num_components = 10;
 double threshold = 10.0;
 // Then if you want to have a cv::FaceRecognizer with a confidence threshold,
 // create the concrete implementation with the appropiate parameters:
 Ptr<FaceRecognizer> model = createEigenFaceRecognizer(num_components, threshold);

 // The following line reads the threshold from the Eigenfaces model:
 double current_threshold = model->getDouble("threshold");
 // And this line sets the threshold to 0.0:
 model->set("threshold", 0.0);

 // Create a FaceRecognizer:
 Ptr<FaceRecognizer> model = createEigenFaceRecognizer();
 // And here's how to get its name:
 String name = model->name();

 // holds images and labels
 vector<Mat> images;
 vector<int> labels;
 // images for first person

 // Create a new Fisherfaces model and retain all available Fisherfaces,
 // this is the most common usage of this specific FaceRecognizer:
 //
 Ptr<FaceRecognizer> model =  createFisherFaceRecognizer();

 // This is the common interface to train all of the available cv::FaceRecognizer
 // implementations:
 //
 model->train(images, labels);

 FaceRecognizer::save("/var/www/html/photos/saved.txt");

Tried to compile that expecting to run it and see the contents of "saved.txt" to later store on a mysql database and do a rerun of this again with any new tagged image (using face detection) that ends up corresponding to the stored value on the database.. but this is all in diapers. I got all of the following errors when trying to compile the code above:

Trying to use face recognition, the facerecognizer

So I copied from http://docs.opencv.org/trunk/modules/contrib/doc/facerec/facerec_api.html

 // Let's say we want to keep 10 Eigenfaces and have a threshold value of 10.0
 int num_components = 10;
 double threshold = 10.0;
 // Then if you want to have a cv::FaceRecognizer with a confidence threshold,
 // create the concrete implementation with the appropiate parameters:
 Ptr<FaceRecognizer> model = createEigenFaceRecognizer(num_components, threshold);

 // The following line reads the threshold from the Eigenfaces model:
 double current_threshold = model->getDouble("threshold");
 // And this line sets the threshold to 0.0:
 model->set("threshold", 0.0);

 // Create a FaceRecognizer:
 Ptr<FaceRecognizer> model = createEigenFaceRecognizer();
 // And here's how to get its name:
 String name = model->name();

 // holds images and labels
 vector<Mat> images;
 vector<int> labels;
 // images for first person

 FaceRecognizer::save("/var/www/html/photos/saved.txt");

Tried to compile that expecting to run it and see the contents of "saved.txt" to later store on a mysql database and do a rerun of this again with any new tagged image (using face detection) that ends up corresponding to the stored value on the database.. but this is all in diapers. I got all of the following errors when trying to compile the code above:

Trying to use face recognition, the facerecognizer

So I copied from http://docs.opencv.org/trunk/modules/contrib/doc/facerec/facerec_api.html

 // Let's say we want to keep 10 Eigenfaces and have a threshold value of 10.0
 int num_components = 10;
 double threshold = 10.0;
 // Then if you want to have a cv::FaceRecognizer with a confidence threshold,
 // create the concrete implementation with the appropiate parameters:
 Ptr<FaceRecognizer> model = createEigenFaceRecognizer(num_components, threshold);

 // The following line reads the threshold from the Eigenfaces model:
 double current_threshold = model->getDouble("threshold");
 // And this line sets the threshold to 0.0:
 model->set("threshold", 0.0);

 // Create a FaceRecognizer:
 Ptr<FaceRecognizer> model = createEigenFaceRecognizer();
 // And here's how to get its name:
 String name = model->name();

 // holds images and labels
 vector<Mat> images;
 vector<int> labels;
 // images for first person
 images.push_back(imread("/var/www/html/photos/1.jpg", CV_LOAD_IMAGE_GRAYSCALE)); labels.push_back(0);

Tried to compile that expecting to run it and see the contents of "saved.txt" to later store on a mysql database and do a rerun of this again with any new tagged image (using face detection) that ends up corresponding to the stored value on the database.. but this is all in diapers. I got all of the following errors when trying to compile the code above:
