我如何在glu.h中摆脱这些编译器错误？

trying to use this tutorial on 64-bit windows 8 with netbeans and cygwin 4.8.1.

尝试在64位Windows 8上使用netbeans和cygwin 4.8.1使用本教程。

i get many errors like this: /usr/include/w32api/GL/glu.h:68:79: error: expected ‘)’ before ‘*’ token.

我得到很多这样的错误：/usr/include/w32api/GL/glu.h:68:79：错误：预期'）'在'*'标记之前。

on statements like this: void APIENTRY gluQuadricCallback(GLUquadric *qobj,GLenum which,void (CALLBACK *fn)());

像这样的语句：void APIENTRY gluQuadricCallback（GLUquadric * qobj，GLenum which，void（CALLBACK * fn）（））;

the pointer on error message points to the * before the fn().

错误消息上的指针指向fn（）之前的*。

edit: including windef.h gets rid of the compiler error messages.

编辑：包括windef.h摆脱编译器错误消息。

i am left with a bunch of undefined references like: glfwInit

我留下了一堆未定义的引用，如：glfwInit

edit2: using André Fischer's ideas, i can get a clean compile (you need to add the directory and a -l option for the linker).

edit2：使用AndréFischer的想法，我可以得到一个干净的编译（你需要为链接器添加目录和-l选项）。

i now have a: skipping incompatible ../../../../../Windows/SysWOW64/opengl32.dll when searching for -lopengl32 and: undefined reference to `_imp_vsnprintf'. so it looks like i have a 32/64 bit problems and an undefined external.

我现在有一个：跳过不兼容的../../../../../Windows/SysWOW64/opengl32.dll，当搜索-lopengl32和：未定义的引用`_imp_vsnprintf'。所以看起来我有一个32/64位问题和一个未定义的外部。

there must be a saner way to get opengl working on windows.

必须有一个更健全的方式让opengl在Windows上工作。

I assume you mean Tutorial 1: Opening a Window and are using Netbeans' builtin build system instead of CMake.

我假设你的意思是教程1：打开一个窗口，并使用Netbeans的内置构建系统而不是CMake。

The order in which you include the header files is important (source). Try it like this:

包含头文件的顺序很重要（源）。试试这样：

#include <windef.h> // According to comments above
#include <GL/glew.h> // Before any gl headers
#include <GL/gl.h>

//#include <GL/glext.h> // Linux headers
//#include <GL/wglext.h> // Windows headers - Not sure which ones cygwin needs. Just try it

#include <GL/glu.h> // Always after gl.h
#include <GL/glfw.h> // When all gl-headers have been included

Create a directory named "include" in your project directory with a subfolder "GL".

使用子文件夹“GL”在项目目录中创建名为“include”的目录。

Grab the binaries (32 bit, MinGW) from the GLFW Download Site and put the .dll/.so into your build-folder (Or extract them somewhere and add them to the search directories) and the header files into "include/GL".

从GLFW下载站点获取二进制文件（32位，MinGW）并将.dll / .so放入您的构建文件夹（或者将它们解压缩并添加到搜索目录中）并将头文件添加到“include / GL”中。

Also the glfw code in the tutorial is slightly outdated; It does not work with glfw3 anymore. You'll have to update it using GLFW's conversion guide/try this version (which I haven't been able to test, since I'm currently not at home) or use glfw2.

此外，教程中的glfw代码稍微过时了;它不再适用于glfw3。您必须使用GLFW的转换指南更新它/尝试此版本（我无法测试，因为我目前不在家）或使用glfw2。

Finally download the GLEW sources and build it by following the instructions in the README.txt. Put the .dll/.so into your build-folder (or add to search directories) and the header files into "include/GL".

最后，按照README.txt中的说明下载GLEW源并构建它。将.dll / .so放入构建文件夹（或添加到搜索目录），将头文件放入“include / GL”。

Add following to your Compiler-Flags:

将以下内容添加到Compiler-Flags：

-Iinclude/

Finally add following arguments to your Linker:

最后将以下参数添加到链接器：

-L/lib -lglu32 -lopengl32 -lGL -lGLU -lglfw -lglew

You should be able to compile the tutorial now.

您应该能够立即编译教程。

Edit: Added instructions for building GLEW, GLFW and completed my answer to include building everything from scratch.
Edit2: Linked glfw3-version of the tutorial-code.
Edit3: Added missing linker options.

编辑：添加了构建GLEW，GLFW的说明，并完成了我的答案，包括从头开始构建所有内容。 Edit2：链接的glfw3-版本的教程代码。 Edit3：添加了缺少的链接器选项。
