red hat 9 下 C 图形程序编译问题.

#include "graphics.h"
int main()
{
     int gdriver, gmode;
     gdriver=VGA;
     gmode=VGAHI;
     initgraph(&gdriver, &gmode, "c:\\tc");
     bar3d(100, 100, 300, 250, 50, 1);       /*画一长方体*/
     getch();
     closegraph();
     return 0;
}
在WIN XP下用TC2.0编译成功.为什么在RED HAT 9 下编译时提示找不到graphics.h.将该文件CP到源程序目录下后出现错误提示:

(bbs限止删了很多行错误提示.)
好多warning好恐怖.这些警告信息我看不懂.请指教.谢谢!

linux 好象没有这个头文件　"graphics.h"
linux 下用ncures库
