SQLCipher + POCO C++

Question

我正试着在我的Mac Lion上用sqlcipher替换POCO的sqlite。关于构建过程和替换，没有太多的信息，但是我想我应该试一试。

我得到了sqlcipher合并，然后我将Data/Sqlite/src Poco目录中的sqlite3.c和sqlite3.h替换为sqlcipher中的sqlite3.c和sqlite3.h，将SQLITE_HAS_CODEC和SQLITE_TEMP_STORE=2参数添加到Makefile中，并尝试构建整个代码。

然而，我得到了以下错误：

以前有人试过这个吗？有没有人知道解决这个问题的潜在方法？谢谢!

这些都是OpenSSL符号，所以您可能没有链接到libcrypto。将-lcrypto添加到链接器标志。
