‘createStereoBM’ was not declared in this scope

Question

I install ubuntu 14.04.3 and opencv3 on my macbook, but when i compile the below code :

#include <opencv2/opencv.hpp>
#include <iostream>
#include <stdio.h>
using namespace std;
using namespace cv;

int main(){
    Ptr<StereoBM> sbm = createStereoBM(16,2);
    return 0;
}

I get error:

stereo.cpp: In function ‘int main()’:
stereo.cpp:8:44: error: ‘createStereoBM’ was not declared in this scope
     Ptr<StereoBM> sbm = createStereoBM(16,2);
                                        ^

I can't find createStereoBM library. I would appreciate any hint. Thanks.

There may possibly be an issue with the 3.0 beta documentation; it appears to reference a cuda function.

The correct function appears to be:

 cv::StereoBM::create

As @berak points out using the current opencv documentation.
