c++ - 由于 undefined reference ,无法链接 Crypto++ Speck 算法

我正在尝试将 Crypto++ 的 Simon 和 Speck 实现用于一个研究项目,但我目前无法编译和链接其 wiki 页面上提供的示例代码。

按照 Crypto++ wiki 的说明,我能够构建库并运行他们的所有测试套件直至完成。我还能够从同一个 wiki 运行示例 AES 代码。仅当我尝试调用 Simon 或 Speck 时才会出现编译错误。

要编译和链接文件,我正在使用 g++ speck_test.cpp -lcryptopp

这是 Crypto++ Speck wiki 上提供的程序。我在我认为必要的地方添加了 include 语句和范围解析。

#include <iostream>
#include <iomanip>

#include "cryptopp/modes.h"
#include "cryptopp/speck.h"
#include "cryptopp/filters.h"

int main(int argc, char* argv[]) {
CryptoPP::SPECK128::Encryption speck;

std::cout << "StaticAlgorithmName: " << speck.StaticAlgorithmName() << std::endl;
std::cout << "AlgorithmName (unkeyed): " << speck.AlgorithmName() << std::endl;

CryptoPP::byte key[CryptoPP::SPECK128::DEFAULT_KEYLENGTH] = {};
speck.SetKey(key, sizeof(key));

std::cout << "AlgorithmName (keyed): " << speck.AlgorithmName() << std::endl;

return 0;
}

根据维基,这个程序的预期输出是

StaticAlgorithmName: SPECK-128
AlgorithmName (unkeyed): SPECK-128
AlgorithmName (keyed): SPECK-128(128)

但是,我从编译器收到以下错误:

如有任何帮助,我们将不胜感激!

最佳答案

正如 dave 所指出的,错误是由于编译器无法找到 CryptoPP 而引起的。

为了解决这个问题,我必须设置 LD_LIBRARY_PATH Ubuntu 上的环境变量以包含库的路径。然后,我不得不更改我的编译器命令以先编译我的文件,然后再链接库,即

g++ -o test.exe speck_test.cpp -L<path-to-cryptopp> -lcryptopp

而不是

g++ -L<path-to-cryptopp> -lcryptopp -o test.exe speck_test.cpp ,这是失败的。
