为什么我把graphics.h复制到devc++的include文件夹下，使用里面的函数时，运行总是说graphics.h出错
#include<graphics.h>
main()
{int gdrive=DETECT,gmode;
registerbgidrive(EGAVGA_drive);
initgraph(&gdrive,&gmode,"c:\\tc");
line(100,100,200,200);
getch();
closegraph();
}
这是我运行的程序；
结果是这样： 展开

将ege ，ege.h ，graphics.h复制到Dev-Cpp\MinGW64\lib\gcc\x86_64-w64-mingw32\4.9.2\include
将压缩包内
lib\mingw64\lib
目录下的
libgraphics64.a
复制，粘贴到
C:\Program Files (x86)\Dev-Cpp\MinGW64\lib\gcc\x86_64-w64-mingw32\4.9.2
目录下
在上方菜单栏选择 工具->编译选项 填入 -lgraphics64 -luuid -lmsimg32 -lgdi32 -limm32 -lole32 -loleaut32
