错误:未定义对`cv :: imread(std :: string const& int)的引用' [英] error: undefined reference to `cv::imread(std::string const&, int)'
问题描述
我是Qt的新手，我有一个项目需要在Qt中配置OpenCV，我试图在Qt中运行一个简单的代码，但出现此错误未定义对cv::imread(std::string const&, int)的引用"
这是我的代码...
I'm new to Qt and I have a project that needs to configure OpenCV in Qt , I tried to run a simple code in Qt but I got this error "undefined reference to cv::imread(std::string const&, int)"
and here is my code...
#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;
}
而我的source.pro是

我看到了所有答案，但是它们没有用. 我的Qt是32位，我的Windows是64位. 我认为我的配置有误.我遵循了许多教程，但是它们不是针对OpenCV 2.4.9的，所以请帮助我...
I saw all the answers about but they didn't work. my Qt is 32bit and my Windows is 64bit. I think my configuration is wrong. I followed many tutorial but they weren't for OpenCV 2.4.9 so please help me ...
推荐答案
查看pkg-config opencv --libs的输出以找出缺少的库，然后将它们添加到配置中.
See output of pkg-config opencv --libs to find out what libraries you're missing, then add them to your config.
对我来说，完整的图书馆清单是
For me, the full list of libraries is
