Question

我正在尝试编译一个简单的opencv程序。我已经设置了环境变量，并且还设置了c ++附加项目的目录dir 额外的链接器目录和输入依赖项（opencv_ts300d.lib和opencv_world300d.lib），但我不断收到此代码的链接器错误：

    #include<iostream>
#include<opencv2\opencv.hpp>
#include<cstdio>
#include <string>
#include <opencv2\core\core.hpp>
#include <opencv2\imgcodecs.hpp>
#include <opencv2\highgui\highgui.hpp>

using namespace std;
using namespace cv;

int main(int argc, char** argv)
{
    cv::Mat a;
    return 0;
}

错误如下：

翻译：

错误1错误LNK2019：未解析的外部符号“void __cdecl＆gt; cv :: fastFree（void *）”（？fastFree @ cv @@ YAXPAX @ Z）在函数“public：＆gt; __ thiscall cv :: Mat中引用：：~Mat（void）“（?? 1Mat @ cv @@ QAE @ XZ）C：\ Users \ Sergio \ documents \ visual studio   2013 \ Projects \ opencvtest \ opencvtest \ Origine.obj opencvtest

Answer 1

当我遇到这种情况时，我正在链接到OpenCV库的x64版本，但是尝试编译成x86（Win32）应用程序。只是改变了32 bit to 64 bit application制作的矿井工作。

Answer 2

尝试

#include <"highgui.hpp">

我不是在我的工作电脑上检查我的来源，但我相信它是这样的。
