Использование криптостатической библиотеки Poco C++ приводит к ошибкам при сборке XCode

Question

Когда я пытаюсь скомпилировать простой тестовый проект с использованием статических библиотек, которые я использовал ранее, то есть Foundation,Net и т. Д. Все работает хорошо, но когда я включаю библиотеку Crypto, я получаю массу ошибок, может ли это быть вызвано зависимостью openssl? Я добавил папку openssl и Poco Foundation,Net, Crypto, а также файлы.a для Foundation,Net, Crypto в настройки сборки в XCode

Код:

//ViewController.h
 #include <Poco/Crypto/CipherFactory.h>
 #include <Poco/Crypto/Cipher.h>
 #include <Poco/Crypto/CipherKey.h>

В моем ViewDidLoad:

//ViewController.mm
std::string headKey = "TESTSTRING";

// encode the string
CipherFactory& factory = CipherFactory::defaultFactory();
// Creates a 256-bit AES cipher
Cipher* pCipher = factory.createCipher(CipherKey("aes-256"));
std::string encrypted = pCipher->encryptString(headKey, Cipher::ENC_BASE64);
std::string decrypted = pCipher->decryptString(encrypted, Cipher::ENC_BASE64);
NSLog([NSString stringWithUTF8String:encrypted.c_str()]);

Answer 1

Проблема не в вашем коде на самом деле. Вам нужно использовать libcrypto.a или же libssl.a который построен на той же платформе. Особенно, если вы используете для симулятора iOS, что это будет для i386 или же arm6 or arm7 в случае устройства. Итак, должна быть библиотека для конкретной платформы. Вы можете получить эту библиотеку кодов с веб-сайтов и скомпилировать с той же архитектурой или создать полную библиотеку, которая будет подходить для нескольких платформ.
