| commented question | Enabling OpenMP while building OpenCV libraries Yes you are correct, but previously i did not know that they are related questions. |

| commented answer | Choosing between "Concurrency" and "TBB" while building OpenCV 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". |

| asked a question | Choosing between "Concurrency" and "TBB" while building OpenCV 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. |

| asked a question | Enabling OpenMP while building OpenCV libraries 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

#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;
