錯誤：'myMD2'沒有命名一個類型

我最近已經對C++和OpenGL編程感興趣，我嘗試了幾種類型的代碼，它們都運行平穩...然後我被要求測試這個代碼，但是由於某種原因，我得到的錯誤所有的時間...現在我失去了我應該做的......錯誤：'myMD2'沒有命名一個類型

myMD2似乎同時用作變量的名稱和類型。這太混亂了，所以考慮改變其中一個**的名字。 – MikeCAT

你介意顯示爲「myMD2.h」的內容嗎？ – MikeCAT

其實它沒有與代碼一起給我...所以我試着在網上找，並發現這在github上#ifndef MY_MD2_H #define MY_MD2_H typedef void * md2_t; md2_t md2_open（const char * filename）; void md2_close（md2_t h）; void md2_desc（md2_t h）; void md2_frame_sample（md2_t _h）; void md2_draw（md2_t h）; #endif – Zhen161

的headerfile myMD2.h沒有定義一個類或稱爲myMD2的結構。從你的其他代碼中，我猜你已經下載了錯誤的頭文件。
