SQLite 3.7.13的加密解密（二）—— 开放宏定义

首先要在sqlite3.c中最前面，添加代码（网上有说在sqlite3.h中添加也可，实际测试在sqlite3.h中打开该宏是无效的）：

#ifndef SQLITE_HAS_CODEC

#define SQLITE_HAS_CODEC

#endif

这个宏是用来确定是否支持加密的。添加上述代码后编译，会出现如下错误：

D:\Research\MySQLite\Debug/../src/sqlite3.c:80963: undefined reference to `sqlite3CodecAttach'

D:\Research\MySQLite\Debug/../src/sqlite3.c:80968: undefined reference to `sqlite3CodecGetKey'
