c++ - 找不到 -lbgi 和 ld 返回 1 退出状态错误

问题描述

我正在尝试使用 dev c++ 在 c++ 图形中绘制线条，这是代码

// C++ Implementation for drawing line 
#include <graphics.h> 

// driver code 
int main() 
{ 
    // gm is Graphics mode which is a computer display 
    // mode that generates image using pixels. 
    // DETECT is a macro defined in "graphics.h" header file 
    int gd = DETECT, gm; 

    // initgraph initializes the graphics system 
    // by loading a graphics driver from disk 
    initgraph(&gd, &gm, ""); 

    // line for x1, y1, x2, y2 
    line(150, 150, 450, 150); 

    // line for x1, y1, x2, y2 
    line(150, 200, 450, 200); 

    // line for x1, y1, x2, y2 
    line(150, 250, 450, 250); 

    getch(); 

    // closegraph function closes the graphics 
    // mode and deallocates all memory allocated 
    // by graphics system . 
    closegraph(); 
}

但是在编译中一次又一次地显示以下错误，我不知道如何解决这些错误。

错误截图

我尝试将这些包含在项目参数链接器选项卡中

另外，我在 devc++ 文件夹中有 graphics.h 库。但不知道为什么这个错误不断弹出。请有人指出我的错误。
