函数_OpenSSLDie中引用的未解析的外部符号__imp____iob_func [英] unresolved external symbol __imp____iob_func referenced in function _OpenSSLDie

问题描述

将我的项目从VS2008迁移到VS2015时，我遇到了错误.

I am getting below error while migrating my project from VS2008 to VS2015.

21>TFCLd.lib(cryptlib.obj) : warning LNK4217: locally defined symbol _fprintf imported in function _OpenSSLDie
21>TFCLd.lib(rsa_sign.obj) : warning LNK4049: locally defined symbol _fprintf imported
21>TFCLd.lib(cryptlib.obj) : error LNK2019: unresolved external symbol __imp____iob_func referenced in function _OpenSSLDie
21>TFCLd.lib(rsa_sign.obj) : error LNK2001: unresolved external symbol __imp____iob_func

该项目在VS2008中构建，但在VS2015中存在上述错误.我可以知道我在想什么吗?

The project builds in VS2008 but with above error in VS2015. May I know what am I missing.

推荐答案

将此内容放在类头文件的开头或stdafx.h

Put this in the begin of your class header file or in stdafx.h

FILE _iob[] = { *stdin, *stdout, *stderr }; 
extern "C" FILE * __cdecl __iob_func(void) { return _iob; }
