我正在尝试用我的Mac Lion上的sqlcipher替换POCO的sqlite。关于构建过程和替换,没有太多信息,但我想我应该试一试。
我有sqlcipher合并,然后我用sqlcipher的那些替换了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中并尝试过建立这整件事。
但是我收到以下错误:

以前有人试过这个吗?有人知道这方面的潜在解决方案吗?谢谢!
答案 0 :(得分:4)
这些是OpenSSL符号,因此您可能没有链接到libcrypto。将-lcrypto
添加到链接器标志。
