error C2248: 'CvSVM::CvSVM' : cannot access private member declared in class 'CvSVM' [closed]

edit

I am trying to use bag of features model and train and SVM. I am using this tutorial and this sample code. I am using Windows 8 and OpenCV 2.4.10. I am running this on Visual Studio 2012. But i am continuously getting this error 'CvSVM::CvSVM' : cannot access private member declared in class 'CvSVM' I tried using OpenCV 2.4.9 but same error is still there.

I searched a lot for this and still could not find a proper solution for this. Please help me on this. Thanks in advance. Below is the code. I am using this Dirent API for Microsoft Visual Studio as well.

EDIT: Lines 146 gives the error. classes_classifiers[class_].train(samples_32f,labels);

This is complete output from visual studio when compiling the main.cpp.
