从C++文件gl3w错误

我有一个项目，我首先用gcc生成gl3w.c，然后用g ++编译我自己的OGLGraphics.cpp文件。 GCC编译成功gl3w.c但是当G ++试图编译包括gl3w.h文件我得到这些错误：从C++文件gl3w错误

我不知道为什么它的工作原理与C文件而不是从C++？

您是否按照GL3W自述文件中概述的步骤操作？具体来说，关于包含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，谢谢！ – grivescorbett 2011-12-22 13:38:21

extern PFNGLDRAWARRAYSPROC gl3wDrawArrays; <—— unknown type name PFNGLDRAWARRAYSPROC

此错误是由在代码中包含的#include <OpenGL/gl.h>如GLTriangleBatch.h引起的。如果你用#include“GL/gl3w.h”代替OpenGL 3/4调用，那么这将消除错误。我认为在不同版本的OpenGL调用之间存在冲突，并导致未知的类型错误当我试图将SuperBible 5代码移植到SB6中时，我遇到了同样的问题。
