Well, I'm trying to do matrix multiplication with gpu::gemm, but occurs fatal error: The function/feature is not implemented (The library was build without CUBLAS) in unknown function and arithm.cpp:72: error: (-213) The library was build without CUBLAS.

I built the OpenCV 2.4.9 with Cmake 2.8.1 and set ON the tag WITH_CUBLAS, but the fatal error occurs again.

Already I used CUDA 5.0 and CUDA 4.2, but yet not working.

What should I do?

Work well with me.

I'm starting a programming GPU using OpenCL 1.2 through 2.8 on AMD OpenCV 2.4.3. When running the code below in visual studio 2010 professional edition, a compilation error occurs. Debugging, I realized that the error is hurrying when HEAP in function void __ cdecl _free_base (void * pBlock).

CODE:

//C++
#include <iostream>
#include <stdio.h>
//OPENCV 2.4.3 WITH OPENCL AMD
#include "opencv2\core\core.hpp"
#include "opencv2\highgui\highgui.hpp"
#include "opencv2\ocl\ocl.hpp"

using namespace std;
using namespace cv;
using namespace cv::ocl;

int main(void)
{

    cout << "Inicial!" << endl;
    vector<cv::ocl::Info> info;
    int ret = getDevice(info,2);
    cout << "Ret: " << ret <<endl;
    return 0;
}

My video card is AMD Radeon HD 6630M in windows 7-64bit.

Thank you and I await response.
