GLEW_APPLE_GLX生成GLEW时导致链接错误 [英] GLEW_APPLE_GLX Causes Linking Error When Building GLEW

问题描述

在尝试解决我的其他问题时，我在GLEW内陷入困境对于Mac，缺少__glewX*符号，并发现它们受到GLEW_APPLE_GLX的保护.

I grepped inside GLEW while trying to solve my other question, concerning missing __glewX* symbols for Mac, and found that they are guarded by GLEW_APPLE_GLX.

当我尝试使用定义了该标志的源代码构建GLEW时，会得到未定义的符号(类似于_glXGetClientString之类的东西).与X11(-lX11)链接无济于事.

When I attempt to build GLEW from source with that flag defined, I get undefined symbols (stuff like _glXGetClientString). Linking against X11 (-lX11) doesn't help.

问题:假设定义GLEW_APPLE_GLX确实有意义，那么我该如何修复构建?

Question: assuming defining GLEW_APPLE_GLX does indeed make sense, how can I fix the build?

推荐答案

在构建使用X Server(XQuartz)而不是CGL的应用程序时，还需要添加-lGL.

When building an application that uses the X Server (XQuartz) instead of using CGL, you also need to add -lGL.

通常，在OS X上构建GL软件时，您使用 OpenGL.framework (-framework OpenGL)，这将为您提供OpenGL和CGL/AGL功能，但省去了GLX.

Ordinarily when building GL software on OS X you use OpenGL.framework (-framework OpenGL) and that gets you OpenGL and CGL/AGL functions but leaves out GLX.

您还应该抛弃任何包含到<OpenGL/gl.h>之类的东西，并改用<GL/gl.h>，因为这将指向/usr/X11R6/include/GL/...而不是OpenGL框架标头.

You should also ditch any includes to things like <OpenGL/gl.h> and use <GL/gl.h> instead, as that will point to /usr/X11R6/include/GL/... instead of the OpenGL framework headers.
