SQLCipher + POCO C++

Question

我正在尝试在我的 Mac Lion 上将 POCO 的 sqlite 替换为 sqlcipher。关于构建过程和替换的信息不多，但是我想我应该试一试。

我已经合并了 sqlcipher，然后我将 Data/Sqlite/src Poco 目录中的 sqlite3.c 和 sqlite3.h 替换为 sqlcipher 的那些，将 SQLITE_HAS_CODEC 和 SQLITE_TEMP_STORE=2 参数添加到 Makefile 并尝试构建这整件事。

但是我收到以下错误：

以前有人试过吗？有人知道对此的潜在解决方法吗？谢谢！

那些是 OpenSSL 符号，所以你可能没有链接到 libcrypto。将-lcrypto 添加到链接器标志。
