我正在創建一個學校項目的骨幹，但我遇到了「無法解析的外部符號」錯誤。根據此網站上提到的以前的問題，我認爲必須手動將我的項目鏈接到.lib文件。問題是，我不知道我需要鏈接到哪個.lib。有人能像我十二歲那樣解釋嗎？另一個LNK2019：無法解析的外部符號

我們應該怎樣知道哪個'.lib'文件？哪一個包含'Birthday :: getDay'和'Birthday :: getMonth'函數的定義？那些不是我知道的任何標準庫的一部分，所以你必須自己寫下它們。 – 2012-02-03 05:05:12
哦，你幫我找出正確的答案。看看我的.cpp文件，我意識到我簡單地將getDay和getMonth函數稱爲「int getDay（）'，而不是'int Birthday :: getDay（）const'。 謝謝！ – derp 2012-02-03 05:21:53
