我在C:\ cryptopp中下载并提取了Crypto ++。我使用Visual Studio Express 2012构建了内部的所有项目(如自述文件中所述),并且一切均已成功构建。然后,我在其他文件夹中创建了一个测试项目,并添加了cryptolib作为依赖项。之后,我添加了include路径,以便可以轻松包含所有标头。尝试编译时,出现有关未解析符号的错误。
为了解决这个问题,我添加C:\cryptopp\Win32\Output\Debug\cryptlib.lib
了链接其他依赖项的链接。现在我得到这个错误:

我也得到:

我尝试编译的代码很简单(我是从另一个站点获得的):
#include <iostream>
#include <string>
#include "sha.h"
#include "hex.h"
using namespace std;
string SHA256(string data) {
byte const* pbData = (byte*) data.data();
unsigned int nDataLen = data.size();
byte abDigest[32];
CryptoPP::SHA256().CalculateDigest(abDigest, pbData, nDataLen);
return string((char*)abDigest);
}
int main(void) {
return 0;
}
任何想法如何解决这一问题?我现在真的只需要SHA-256,别无其他。我正在使用Windows 7 64位,并且今天下载了VS C ++,因此它应该是最新版本。
