從C++文件gl3w錯誤

我有一個項目，我首先用gcc生成gl3w.c，然後用g ++編譯我自己的OGLGraphics.cpp文件。 GCC編譯成功gl3w.c但是當G ++試圖編譯包括gl3w.h文件我得到這些錯誤：從C++文件gl3w錯誤

我不知道爲什麼它的工作原理與C文件而不是從C++？

您是否按照GL3W自述文件中概述的步驟操作？具體來說，關於包含gl3w.h的部分首先是，之前的任何OpenGL文件。

哦，之前window.h，其中可以包括gl.h。

是的，我在gl3w之前包含了glfw，謝謝！ – grivescorbett 2011-12-22 13:38:21

extern PFNGLDRAWARRAYSPROC gl3wDrawArrays; <—— unknown type name PFNGLDRAWARRAYSPROC

此錯誤是由在代碼中包含的#include <OpenGL/gl.h>如GLTriangleBatch.h引起的。如果你用#include「GL/gl3w.h」代替OpenGL 3/4調用，那麼這將消除錯誤。我認爲在不同版本的OpenGL調用之間存在衝突，並導致未知的類型錯誤當我試圖將SuperBible 5代碼移植到SB6中時，我遇到了同樣的問題。
