Question

我已将graphics.h和winbgim.h库以及libbgi.a添加到MinGW。他们都可以找到here。存档具有文件夹，指示应将其放置在/MinGW下的目录。我还将-lbgi -lgdi32 -lcomdlg32 -luuid -loleaut32 -lole32添加到了额外的链接选项，如以下链接中所指定：http://www.infobits.ro/medii-mingw-developer-studio3.php。（对不起，这是罗马尼亚语，但图片很容易理解）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;
}

我收到错误日志，其中包含“未定义的引用错误”。错误日志是：

有什么想法吗？
