OpenGL GLFW/GLEW编程

Question

我想学习使用着色器，因此在Netbeans（ver。8.0.2）上创建了一个新的C++项目。

我想包括GLFW和GLEW库就像在本教程中指出：http://www.learnopengl.com/#!Getting-started/Creating-a-window

我目前struggeling在正常进口GLEW。当使用#include <GL/glew.h>时，编译器（我在Windows10x64/Cygwin控制台上使用GNU g ++）会引发大量错误。这似乎是glu.h的问题。为了测试的目的，我去掉了glew.h中的glu.h。这消除了错误，但也阻止了openGL完全加载（以gl开头的函数“未定义”，如glViewport）。所以这不可能是解决方案。

输出呼吁正常glew.h编译时，我得到：

g++ -m64 -c -g -Wall -I/cygdrive/C/Users/Erik/programming/Libraries/glew-1.13.0-win32/glew-1.13.0/include/ -I/cygdrive/C/Users/Erik/programming/Libraries/glfw-3.1.2.bin.WIN32/glfw-3.1.2.bin.WIN32/include/ -std=c++11 -MMD -MP -MF "build/Debug/Cygwin-Windows/startup.o.d" -o build/Debug/Cygwin-Windows/startup.o startup.cc

对我来说，（我是用C无亲++，因此不会在解释错误消息非常好）好像CALLBACK尚未定义。任何想法如何解决这个问题？

Answer 1

我解决它以某种方式（不漂亮，但至少以某种方式）：

我试图导入windef.h像link from @Louen说明。 这删除了CALLBACK-Error，但创建了一个新的（关于APIENTRY的东西）。所以，我搜索了WINDEF.H的错误，解决一部分，并发现它：

#ifndef CALLBACK 
#if defined(_ARM_) 
#define CALLBACK 
#else 
#define CALLBACK __stdcall 
#endif 
#endif 

然后我就粘贴这在我的文件（而不是包括全WINDEF.H）。
