Where are the OpenGL header files located on MacOSX?
提问by anon
In /usr/include ,
在 /usr/include 中，
I tried grepping for GL gl and OpenGL .. .but can't find it.

They are located at /System/Library/Frameworks/OpenGL.framework/Headers. To include them, just use:
它们位于 /System/Library/Frameworks/OpenGL.framework/Headers。要包含它们，只需使用：
#include <OpenGL/gl.h>
#include <OpenGL/glu.h>
#include <OpenGL/glext.h>
#include <GLUT/glut.h>
etc. Make sure to link against the appropriate frameworks, eg)
等。确保链接到适当的框架，例如）
cc <your_file.c> -framework GLUT -framework OpenGL
for OpenGL and GLUT
对于 OpenGL 和 GLUT

This is a good old thread to revive, because the correct answer changed. The accepted answer of /System/Library/Frameworks/OpenGL.framework/Headerswas totally correct when it was written. But with Xcode 5 (I believe it changed with Xcode 4 already), this is not the case anymore.
这是一个很好的旧线程，因为正确答案已更改。被接受的答案/System/Library/Frameworks/OpenGL.framework/Headers在写的时候是完全正确的。但是对于 Xcode 5（我相信它已经随着 Xcode 4 改变了），情况不再如此。
All SDK files are now installed into /Applications/Xcode.app. The exact location of the headers depends on the platform the application is built against. As an example, the OpenGL headers for OS X 10.9 are in:
所有 SDK 文件现在都安装到/Applications/Xcode.app. 标头的确切位置取决于构建应用程序的平台。例如，OS X 10.9 的 OpenGL 头文件在：
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk/System/Library/Frameworks/OpenGL.framework/Headers
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk/System/Library/Frameworks/OpenGL.framework/Headers

It's worth noting that one also needs to have XCode itself set up (not just installed), as well as the XCode Command-Line Tools, even if one is not building the application in XCode.
值得注意的是，即使不是在 XCode 中构建应用程序，也需要设置 XCode 本身（不仅仅是安装）以及 XCode 命令行工具。

XCode automatically exposes all header files from a framework added to a project via the framework's name.
So, "cocoa.h"is part of "cocoa.framework"- hence #include <cocoa/cocoa.h>
XCode 会自动公开框架中通过框架名称添加到项目中的所有头文件。所以，"cocoa.h"是"cocoa.framework"- 因此的一部分#include <cocoa/cocoa.h>
OpenGl is included <OpenGL/gl.h>rather than the more expected <GL/gl.h>on other platforms.
包含 OpenGl<OpenGL/gl.h>而不是<GL/gl.h>其他平台上更多的预期。

In MacOS 10.12.6, they're under /opt/X11/include, e.g. /opt/X11/include/GL/gl.h.
在MacOS上10.12.6，他们是下/opt/X11/include，例如/opt/X11/include/GL/gl.h。
