我有添加graphics.h和winbgim.h库，还有libbgi.aMinGW。它们都可以在这里找到。存档有文件夹，这些文件夹指示它们应该放在的目录/MinGW。我还添加-lbgi -lgdi32 -lcomdlg32 -luuid -loleaut32 -lole32了额外的链接选项，如以下链接中所述：http: //www.infobits.ro/medii-mingw-developer-studio3.php。（对不起，它是罗马尼亚语，但图像很容易理解）。
当我尝试运行以下代码时： 

#include <graphics.h>
#include <iostream>

using namespace std;

int main() {
    int gdriver = DETECT, gmode;
    initgraph(&gdriver, &gmode, "");
    if (graphresult()) {
        cout<<"Tentativa nereusita ...";
    }
    else {
        cout<<"Everything is working!";
        setcolor(RED);
        moveto(0,0);
        lineto(getmaxx(),getmaxy());
    }
    cout<<endl<<"Press anything to close";
    getch();
    return 0;
}

我收到带有“未定义参考错误”的错误日志。错误日志是：

任何想法？
