我是 Qt 新手，我有一个需要在 Qt 中配置 OpenCV 的项目，我尝试在 Qt 中运行一个简单的代码，但出现此错误“未定义的引用”cv::imread(std::string const&, int)”
这是我的代码...
#include "opencv2/imgproc/imgproc.hpp"
#include "opencv2/highgui/highgui.hpp"
using namespace cv;
int main(){
Mat src,gray;
src=imread("C:/Users/user/Desktop/wood-pattern.png",1);
imshow("gg",src);
cvWaitKey(0);
return 0;
}
我的 source.pro 是

我看到了所有的答案，但它们不起作用。
我的 Qt 是 32 位，我的 Windows 是 64 位。
我认为我的配置是错误的。我遵循了很多教程，但它们不适用于 OpenCV 2.4.9，所以请帮助我......
查看输出pkg-config opencv --libs找出您缺少的库，然后将它们添加到您的配置中。
对我来说，图书馆的完整列表是
