thank you.

Yes you are correct, but previously i did not know that they are related questions.

So this means that i cannot have "TBB" , "OpenMP", "C=" , "GDC" all at the same. It simply means that support has been added for all of them which previously had only support for "TBB".

Hi All

I am building OpenCV from source to get every bit of performance out of it. So in the process of doing that I see that if I choose "TBB" the "Concurrency" gets automatically disabled.

I like to know which is efficient. Obviously I know its "TBB" but what is "Concurrency" mean here.

hi all

I am trying to build libraries for openCV. i see a log in cmake like this

  Other third-party libraries:
    Use IPP:                     NO
    Use Eigen:                   YES (ver 3.2.0)
    Use TBB:                     YES (ver 4.2 interface 7000)
    Use OpenMP:                  NO
    Use GCD                      NO
    Use Concurrency              NO
    Use C=:                      NO
    Use Cuda:                    NO
    Use OpenCL:                  NO

You can see that it has OpenMP switched off. Is there a way to enable it. My platform details are as below :

  Platform:
    Host:                        Windows 6.1 AMD64
    CMake:                       2.8.11.2
    CMake generator:             Visual Studio 11 Win64
    CMake build tool:            C:/Windows/Microsoft.NET/Framework/v4.0.30319/MSBuild.exe
    MSVC:                        1700
2013-08-12 11:33:23 -0600 asked a question image loads well but i see errors in the output window of vs2012

hi i am a beginner. the following code is used for displaying an image. the program does display an image but i see errors in the output window of vs2012. i want to know if i am doing the right thing here. i use C:\opencv\build\x64\vc11 as the path for opencv and used vs2012.

#include "stdafx.h"
#include <opencv2/opencv.hpp>
#include <iostream>
using namespace cv;
using namespace std;
int main( int argc, char** argv )
{
    Mat image;
    image = imread("C:\\jobs.jpg", CV_LOAD_IMAGE_COLOR);   // Read the file
    namedWindow( "Display window", CV_WINDOW_AUTOSIZE );// Create a window for display.
    imshow( "Display window", image );                   // Show our image inside it.
    waitKey(0);                                          // Wait for a keystroke in the window
    return 0;
}

OUTPUT of output window.
