如何知道为 Ubuntu 12.04 上构建的 OpenCV 2.3.1 设置了哪些标志? [英] How to know which flags have been set for OpenCV 2.3.1 built on Ubuntu 12.04?

问题描述

我需要在一台已经构建了 OpenCV 的计算机上工作，而不是我的.但是，我想知道在构建时设置了哪些标志，例如WITH_TBB= 、 WITH_CUDA= 等.有没有办法从某个文件中获取这些信息?

I need to work on a computer, not mine, where OpenCV is already built. However, I would like to know which flags have been set when it was built, e.g. WITH_TBB= , WITH_CUDA= , and so on. Is there a way to get this information from some file?

推荐答案

只需运行这个:

#include <opencv2/opencv.hpp>
#include <iostream>

int main()
{
    // Get build information
    std::cout << cv::getBuildInformation();
}

它产生如下输出:
