在easyx.h中将void *__imp___iob_func=0注释掉报错EasyX.GraphWnd.cpp:(.text+0x198c): undefined reference to `__imp___iob_func'

#pragma once

//void *__imp___iob_func=0; //练习添加的 

ifndef WINVER
#define WINVER 0x0400           // Specifies that the minimum required platform is Windows 95 and Windows NT 4.0.
#endif

而不将其注释掉编译时报错
