sqlite - SQLCipher + POCO C++

Question

我正在尝试用 sqlcipher 替换 POCO 的 sqlite|在我的 Mac Lion 上。关于构建过程和替换的信息不多，但我想我应该试一试。

我有 sqlcipher 合并，然后我用 sqlcipher 替换了 Data/Sqlite/src Poco 目录中的 sqlite3.c 和 sqlite3.h，将 SQLITE_HAS_CODEC 和 SQLITE_TEMP_STORE=2 参数添加到 Makefile 并尝试构建这一切。

但是我收到以下错误:

有没有人试过这个？有人知道这个的潜在解决方法吗？谢谢!

那些是 OpenSSL 符号，因此您可能没有链接到 libcrypto。将 -lcrypto 添加到链接器标志。
