您好，当我尝试编译我的 MySQL 连接代码时，我收到了这些 LNK 错误

1>main.obj : error LNK2028: unresolved token (0A00027D) "extern "C" struct st_mysql * __stdcall mysql_init(struct st_mysql *)" (?mysql_init@@$$J14YGPAUst_mysql@@PAU1@@Z) referenced in function "int __cdecl main(void)" (?main@@$$HYAHXZ)

您没有与 MySQL 库链接。

仅仅包含头文件是不够的，项目现在必须在哪里找到 MySQL 可执行代码。您可以通过指定要引入哪些库来告诉它。

在线文档中有一个部分详细说明了您需要做什么，这基本上是将libmysql（假设动态链接，请参阅该链接以获取您想要的静态案例的链接）库到项目中。
