【问题描述】：
我在 OS X 10.7 上使用 TextEdit 和 gcc 来制作小型终端程序。我正在尝试学习如何编写 OpenSSL，但我正在编译戏剧（由于已弃用的问题 - 更多信息见下文）。我已经在 SO 上进行了谷歌搜索和搜索，但我阅读的所有内容要么是 2011 年之前（问题似乎出现时），特定于 iOS（我正在为 OS X 编程，但试图独立于平台）或谈论使用 XCode（我不喜欢 - 我更喜欢 TextEdit）。
谁能指出如何使用 gcc 在 OS X 上安装 OpenSSL 程序的简单分步过程的正确方向？
为了记录，这是我采取的确切步骤：
通过 macports 安装 OpenSSL
“openssl 版本”返回“OpenSSL 1.0.1e 2013 年 2 月 11 日”
我正在尝试编译这个文件：http://saju.net.in/code/misc/openssl_aes.c.txt
我已重命名为“aes.c”，并且正在使用“gcc -o aes aes.c”
我尝试了以下标志（没有结果）：-lcrypto、lssl、-Wno-error=deprecated-declarations
我从 gcc 得到的具体输出如下：
Brads-MacBook-Air:Desktop brad$ gcc -o aes aes.c -lssl -lcrypto -Wno-error=deprecated-declarations

通常，您避免使用 Apple 的 0.9.8 版本的 OpenSSL。它缺少 TLS 1.1 和 1.2，缺少对 EC 等的完全支持。要在 OS X 上构建 OpenSSL，请参阅 OpenSSL wiki 上的 Compilation and Installation。我编写了 OS X 说明，所以我知道它们可以工作。
