錯誤LNK2028：無法解析令牌錯誤

Question

你好我得到這些LNK錯誤，當我嘗試編譯我的MySQL連接代碼

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)

你不能與MySQL庫進行鏈接。

僅僅包含頭文件是不夠的，項目現在必須在哪裏找到MySQL可執行代碼。你可以通過指定要引入的庫來告訴它。

有一個section in the online docs它詳細說明你需要做什麼，它基本上是添加libmysql（假設動態鏈接，請參閱關於靜態情況下的鏈接你想要那個）圖書館的項目。
