【问题描述】:
系统信息: Ubuntu 11.10(64 位)和 OpenCV 2.3(今天安装)
我正在尝试在 OpenCV 2.3 中编译一些非常简单的代码,但我遇到了一个奇怪的错误。
#include <opencv2/core/core.hpp>
#include <opencv2/highgui/highgui.hpp>
int main(){
cv::Mat image=cv::imread("img.jpg");
cv::namedWindow("My Image");
cv::imshow("My Image",image);
cv::waitKey(0);
return 1;
}
但是,我收到了这些错误消息...
