Visual Studio Intellisense会找到函数，但编译器不会

Question

我正在与OpenSSL一起尝试使SHA512哈希函数正常工作。当我编写代码时，Visual Studio的intellisense会发现函数<div class="box" data-number="6"> Some text here </div> <div class="box" data-number="7" style="--d:30px"> Another text here </div>以及其中包含的所有参数，但是当我构建项目时，出现错误“未解析的外部符号SHA512在函数main中引用。”到目前为止，这是基于一个小示例here的结果。

stdafx.h

SHA512

test.cpp

// stdafx.h : include file for standard system include files,
// or project specific include files that are used frequently, but
// are changed infrequently
//

#pragma once

#include "targetver.h"

#include <stdio.h>
#include <tchar.h>
#define _ATL_CSTRING_EXPLICIT_CONSTRUCTORS      // some CString constructors will be explicit
#define _AFX_NO_MFC_CONTROLS_IN_DIALOGS         // remove support for MFC controls in dialogs

#ifndef VC_EXTRALEAN
#define VC_EXTRALEAN            // Exclude rarely-used stuff from Windows headers
#endif

#include <afx.h>
#include <afxwin.h>         // MFC core and standard components
#include <afxext.h>         // MFC extensions
#ifndef _AFX_NO_OLE_SUPPORT
#include <afxdtctl.h>           // MFC support for Internet Explorer 4 Common Controls
#endif
#ifndef _AFX_NO_AFXCMN_SUPPORT
#include <afxcmn.h>                     // MFC support for Windows Common Controls
#endif // _AFX_NO_AFXCMN_SUPPORT

#include <iostream>



// TODO: reference additional headers your program requires here
#include <openssl/sha.h>

我什至检查并确认SHA512也位于stdafx.h文件中的sha.h文件中。
