我试图在Mac Lion上用sqlcipher替换POCO的sqlite。关于构建过程和替换的信息不多，但是我认为应该尝试一下。
我已经将sqlcipher合并，然后用sqlcipher的目录替换了Data / Sqlite / src Poco目录中的sqlite3.c和sqlite3.h，并在Makefile中添加了SQLITE_HAS_CODEC和SQLITE_TEMP_STORE = 2参数，并尝试构建它整件事情。
但是我收到以下错误：

有人尝试过吗？有人知道对此有潜在的解决方法吗？谢谢！
最佳答案
这些是OpenSSL符号，因此您可能未针对libcrypto进行链接。将-lcrypto添加到链接器标志。
