我正在用pjsip开源库开发aes加密。用于aes加密的库不是c编程中提供的内置库。所以，我使用外部库（libmcrypt）进行aes加密。
我通过这个网站把libmcrypt库构建到我的机器（mac osx）中。
https://coolestguidesontheplanet.com/install-mcrypt-php-mac-osx-10-10-yosemite-development-server/
https://gist.github.com/bricef/2436364
在构建这些库时，它在/usr/local/lib/path中创建了一个动态库（libmcrypt.dylib）。当使用lipo-info libmcrypt.dylib命令检查该库的体系结构时，它显示
Non-fat file: libmcrypt.dylib is architecture: x86_64
但我正在使用pjsip为android和ios设备创建这些应用程序。他们的架构是armeabi（android）和armv7（ios）。
在将libmcrypt.dylib（x86_64）链接到pjsip库（armv7）时，显示以下错误。
Undefined symbols for architecture armv7:

我对这些建筑不太了解。是否可以将libmcrypt.dylib（x86_64）转换为libmcrypt.dylib（armv7）。如果是，那么请指导我如何将其转换为ARMV7体系结构，如果不是，那么请为浪费您的时间而道歉。
提前谢谢！

不要用麦克里特。mcrypt库尚未updated since 2007。切换到openssl或另一个维护的加密项目。
PJSIP文档说明了如何在iOS和Android设备上使用OpenSSL：
