是否可以在 VSCode 中使用 MinGW 编译 cryptopp？

Question

我下载了一个 cryptopp 8.7.0 并尝试在

VSCode

中编译它。

编译参数：

A:\msys64\mingw64\bin\g++.exe -g A:\folder\AES256_GSM_C++\test.cpp -static -static-libgcc -static-libstdc++ -lcrypto++ -o A:\Andrey_dev\AES256_GSM_C++\test.exe

如果我尝试编译我的代码，我会得到以下错误：

a:/msys64/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/12.2.0/../../../../x86_64-w64-mingw32/bin/ld.exe: cannot find -lcrypto++: No such file or directory

（注意：与

-lcryptopp

相同的错误，没有目录）

代码：

#include "cryptopp/cryptlib.h"
#include "cryptopp/rijndael.h"
#include "cryptopp/modes.h"
#include "cryptopp/files.h"
#include "cryptopp/osrng.h"
#include "cryptopp/hex.h"

#include <iostream>
#include <string>
#include <windows.h>

using namespace std;

int main(int argc, char *argv[])
{
    using namespace CryptoPP;

    AutoSeededRandomPool prng;
    HexEncoder encoder(new FileSink(std::cout));

    SecByteBlock key(AES::DEFAULT_KEYLENGTH);
    SecByteBlock iv(AES::BLOCKSIZE);

    prng.GenerateBlock(key, key.size());
    prng.GenerateBlock(iv, iv.size());

    std::string plain = "CBC Mode Test";
    std::string cipher, recovered;

    std::cout << "plain text: " << plain << std::endl;

    /*********************************\

    try
    {
        CBC_Mode<AES>::Encryption e;
        e.SetKeyWithIV(key, key.size(), iv);

        StringSource s(plain, true,
                       new StreamTransformationFilter(e,
                                                      new StringSink(cipher)) // StreamTransformationFilter
        );                                                                    // StringSource
    }
    catch (const Exception &e)
    {
        std::cerr << e.what() << std::endl;
        exit(1);
    }

    /*********************************\

    std::cout << "key: ";
    encoder.Put(key, key.size());
    encoder.MessageEnd();
    std::cout << std::endl;

    std::cout << "iv: ";
    encoder.Put(iv, iv.size());
    encoder.MessageEnd();
    std::cout << std::endl;

    std::cout << "cipher text: ";
    encoder.Put((const BYTE *)&cipher[0], cipher.size());
    encoder.MessageEnd();
    std::cout << std::endl;

    /*********************************\

    try
    {
        CBC_Mode<AES>::Decryption d;
        d.SetKeyWithIV(key, key.size(), iv);

        StringSource s(cipher, true,
                       new StreamTransformationFilter(d,
                                                      new StringSink(recovered)) // StreamTransformationFilter
        );                                                                       // StringSource

        std::cout << "recovered text: " << recovered << std::endl;
    }
    catch (const Exception &e)
    {
        std::cerr << e.what() << std::endl;
        exit(1);
    }

    return 0;
}

此外，我尝试在

-L ${fileDirname}\\cryptopp

中使用 write

tasks.json

，我得到了许多未定义的引用：

我没有显示所有错误，实际上还有更多。

有什么想法吗？

编辑：当我使用

cryptopp

安装

MSYS2

时，大多数问题都消失了，但在

libcryptopp.a

中出现了未定义引用的另一个问题

错误：
