【问题描述】:
我正在尝试在 MS Visual Studio C++ 2012 中编译解决方案。
我的代码使用 marshallsoft AES 库。
我为库添加了这些并包含路径:
-
C:\aes4c\APPS到Configuration properties->VC++ Directories->Include Directories -
C:\aes4c\DLLS到Configuration properties->VC++ Directories->Library Directories
当我编译单个 .cpp 文件时,它编译没有问题,但是当我构建解决方案时,我得到:
------ Build started: Project: cryptest2, Configuration: Debug Win32 ------
cryptest2.obj : error LNK2019: unresolved external symbol __imp__aesAttach@8 referenced in function "int __cdecl EncryptFileW(char *,char *)" (?EncryptFileW@@YAHPAD0@Z)
cryptest2.obj : error LNK2019: unresolved external symbol __imp__aesEncryptFile@12 referenced in function "int __cdecl EncryptFileW(char *,char *)" (?EncryptFileW@@YAHPAD0@Z)
cryptest2.obj : error LNK2019: unresolved external symbol __imp__aesInitAES@20 referenced in function "int __cdecl EncryptFileW(char *,char *)" (?EncryptFileW@@YAHPAD0@Z)
C:\Users\ariyan\documents\visual studio 2012\Projects\cryptest2\Debug\cryptest2.exe : fatal error LNK1120: 3 unresolved externals
========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========
有什么问题?
我该如何解决?
我的代码是:
#include "stdafx.h"
#include <windows.h>
#include <stdio.h>
#include "aes.h"
int EncryptFile(char *KeyBuffer, char *FileName);
int _tmain(int argc, _TCHAR* argv[])
{
EncryptFile("1234567890abcdef","c:\test.txt");
return 0;
}
int EncryptFile(char *KeyBuffer, char *FileName)
{int Code;
// attach DLL
Code = aesAttach(0, 0);
if(Code<0)
{printf("ERROR %d: Cannot attach\n", Code);
return FALSE;
}
printf("Will encrypt file in CBC mode\n");
Code = aesInitAES((char *)KeyBuffer, NULL, AES_ECB_MODE, AES_ENCRYPT, NULL);
if(Code<0)
{printf("aesInitAES fails\n");
return FALSE;
}
printf("Encrypt file...\n");
Code = aesEncryptFile(NULL, KeyBuffer, FileName);
if(Code<0)
{printf("aesEncryptFile fails\n");
return FALSE;
}
printf("%d bytes encrypted\n", Code);
return Code;
}
