OpenGL GLFW/GLEW編程

Question

我想學習使用着色器，因此在Netbeans（ver。8.0.2）上創建了一個新的C++項目。

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

我目前struggeling在正常進口GLEW。當使用#include <GL/glew.h>時，編譯器（我在Windows10x64/Cygwin控制檯上使用GNU g ++）會引發大量錯誤。這似乎是glu.h的問題。爲了測試的目的，我去掉了glew.h中的glu.h。這消除了錯誤，但也阻止了openGL完全加載（以gl開頭的函數「未定義」，如glViewport）。所以這不可能是解決方案。

輸出呼籲正常glew.h編譯時，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

對我來說，（我是用C無親++，因此不會在解釋錯誤消息非常好）好像CALLBACK尚未定義。任何想法如何解決這個問題？

Answer 1

我解決它以某種方式（不漂亮，但至少以某種方式）：

我試圖導入windef.h像link from @Louen說明。 這刪除了CALLBACK-Error，但創建了一個新的（關於APIENTRY的東西）。所以，我搜索了WINDEF.H的錯誤，解決一部分，並發現它：

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

然後我就粘貼這在我的文件（而不是包括全WINDEF.H）。
