C图形库错误

Question

我有以下代码:

#include<stdio.h>
#include<conio.h>
#include<math.h>
#include<graphics.h>
void main()
{
    int gd=DETECT,gm;
    int dx,dy,p,end;
    float x1,x2,y1,y2,x,y;
    initgraph(&gd,&gm,"");
    printf("\nEnter the value of x1: ");
    scanf("%f",&x1);
    printf("\nEnter the value of y1: ");
    scanf("%f",&y1);
    printf("\nEnter the value of x2: ");
    scanf("%f",&x2);
    printf("\nEnter the value of y2: ");
    scanf("%f",&y2);
    dx=abs(x1-x2);
    dy=abs(y2-y1);
    p=2*dy-dx;

    if(x1>x2)
    {
        x=x2;
        y=y2;
        end=x1;
    }
    else
    {
        x=x1;
        y=y1;
        end=x2;
    }
    putpixel(x,y,10);
    while(x<end)
    {
        x=x+1;
        if(p<0)
        {
            p=p+2*dy;
        }
        else
        {
            y=y+1;
            p=p+2*(dy-dx);
        }
        putpixel(x,y,10);
    }
    getch();
    closegraph();
}

代码主要用于创建一条线.但是当我运行这个程序时,我在控制台中收到错误消息(我使用的是Ubuntu 10.04版本):

test.c:2: fatal error: conio.h: No such file or directory compilation terminated. test.c:2: fatal error: graphics.h: No such file or directory compilation terminated.

这是否意味着我必须在C路径中添加一些lib？

提前致谢.

conio.h并且graphics.h是我认为来自Borland环境的古老的非标准接口.
