undefined reference
基本解釋
- 未定義的引用錯誤
- 符號未找到
英漢例句
- Similar to an undefined external error, except that the reference is via metadata.
與未定義的外部錯誤類似，不同的是引用是通過元數(shù)據(jù)。 - They hold only one piece of data: a string, a number, the undefined value, a reference to another variable.
它只保存一段數(shù)據(jù)：一個字符串、一個數(shù)字、未定義的值以及對另一個變… - Note that had we declared the reference i without the const qualifier, the function f() could have modified its argument, thereby causing undefined behavior.
注意我們沒有將i聲明為靜態(tài)類型，但是函數(shù)f仍有可能修改它的這個參數(shù)，這將引起異常。 - Undefined reference, what was the solution last time?
未定義的引用，上次我們是怎么解決的呢？
