Impossible de lier le projet C++ avec les bibliothèques statiques openssl

Question

J'ai un projet réalisé en C++ et j'ai besoin de le compiler pour Windows XP et plus tard.

Ceci est le fichier d'en-tête de ma classe RsaEncryptor (je pense qu'il est indifférent de publier des sources ici, parce que je suis sûr à 100% que ça fonctionne bien, mais si nécessaire):

#ifndef RSAENCRYPTOR_H_ 
#define RSAENCRYPTOR_H_ 

#include <stdexcept> 
#include <openssl/rsa.h> 
#include <openssl/engine.h> 
#include <openssl/pem.h> 

// One of this paddings can be used 
//#define PADDING RSA_PKCS1_OAEP_PADDING 
#define PADDING RSA_PKCS1_PADDING 
//#define PADDING RSA_NO_PADDING 

class RsaEncryptor { 

private: 

    RSA* publicKey; 
    RSA* privateKey; 

public: 

    RsaEncryptor() { 
     publicKey = nullptr; 
     privateKey = nullptr; 
    } 

    ~RsaEncryptor() { 
     if (this->publicKey) 
      RSA_free(this->publicKey); 
     if (this->privateKey) 
      RSA_free(this->privateKey); 
    } 

    size_t GetCipherBytesCount() { 
     return 172; //is default for 1024 bit key length 
    } 

    void SetPublicKeyFromString(const std::string& content); 
    void SetPrivateKeyFromString(const std::string& content); 

    std::string Encrypt(const std::string& plainData); 
    std::string Decrypt(const std::string& cipherData); 

}; 


#endif /* RSAENCRYPTOR_H_ */ 

J'utilise toute dernière version de Eclipse Neon pour le développement de C sur la machine Windows 10 x64.

Aussi j'ai lu this:

(...) you will need to configure with no-async when building OpenSSL 1.1.0 and above for Windows XP or Vista

Et je suis guidé par following instructions.

Qu'est-ce que je fais:

1. installer Ubuntu 17.04 x64 dans Virtual Box sous Windows 10 x64.

2. télécharger la dernière version de la bibliothèque OpenSSL Ubuntu

3. installer mxe et toutes les exigences (mais ne peut pas compiler avec elle et je décide d'utiliser mingw32)

4. installer mingw32 via root@user-pc:/home/user# apt-get install gcc-mingw-w64-i686

5. décompresser la bibliothèque OpenSSL dans /home/user/openssl-x32

6. aller à /home/user/openssl-x32

7. run ./Configure mingw --cross-compile-prefix=i686-w64-mingw32 --prefix=/home/user/builds/openssl-x32-static no-shared no-async

8. run make

9. run make install

10. copie libssl.a et libcrypto.a de /home/user/builds/openssl-x32-static/lib à la machine hôte (Windows 10 x64) to folder E:\MyProjects\my-app\libraries\

11. copie include répertoire de Ubuntu pour accueillir la machine dans le dossier E:\MyProjects\my-app\include

12. Ajouter libraries dossier aux configurations de l'éditeur de liens

13. Ajouter include dossier compilateur configurations

14. Ensuite, je construis mon projet mais j'ai la suite answer:

11:58:21 Build Finished (took 11s.567ms)

J'ai juste besoin de lier mon projet C++ terminé avec la bibliothèque OpenSSL correctement compilée (avec le flag no-async) pour le laisser fonctionner sous les anciennes versions de Windows.

Je serai heureux de recevoir de l'aide pour ce problème.

Answer 1

La plupart sinon la totalité des symboles non définis dans votre journal des erreurs proviennent de Winsock. Essayez de créer un lien avec -lws2_32.
