您好我在尝试编译MySQL连接代码时遇到这些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)

提前谢谢

您没有链接MySQL库。

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的库来告诉它。

有一个section in the online docs详细说明了你需要做什么，基本上是添加libmysql（假设动态链接，请参阅静态情况的链接，而不是你希望的那个）图书馆到项目。
