Include statement: can't find SDL/SDL.h file
提问by bernie2436
My understanding is that when I build a C++ project in xcode and I have an include line in one of my C files in angle-bracket formthen the C++ compiler that works with xcode looks in /System/Library/Frameworks/to find the file. I think that because of this answer: when I use the line #include <OpenGL/gl.h> in my xcode project, where does it look for the gl.h file?
我的理解是，当我在 xcode 中构建 C++ 项目并且在我的一个 C 文件中以尖括号形式包含一行时，与 xcode 一起使用的 C++ 编译器/System/Library/Frameworks/会查找该文件。我认为因为这个答案：当我在我的 xcode 项目中使用 #include <OpenGL/gl.h> 行时，它在哪里查找 gl.h 文件？
I have an SDL.h file at /System/Library/Frameworks/SDL.framework/headers/SDL.h(I downloaded the folder SDL.framework and copied it to that location with the command sudo cp -r /Volumes/SDL/SDL.framework System/Library/Frameworks)
我有一个 SDL.h 文件/System/Library/Frameworks/SDL.framework/headers/SDL.h（我下载了文件夹 SDL.framework 并使用命令将其复制到该位置sudo cp -r /Volumes/SDL/SDL.framework System/Library/Frameworks）
But my include statement in one of the files in my xcode project still gives this error:
但是我在我的 xcode 项目中的一个文件中的 include 语句仍然给出了这个错误：
#include <SDL/SDL.h> //throws file not found
Did I properly install the SDL framework? Why doesn't xcode see it?
我是否正确安装了 SDL 框架？为什么 xcode 看不到它？

Under your projects Build Settings, do a search for "search". Add a header search path to the SDL directory /System/Library/Frameworks/SDL.framework/headers
在您的项目Build Settings 下，搜索“search”。添加标头搜索路径到 SDL 目录/System/Library/Frameworks/SDL.framework/headers
Should be able to just do this after:
应该能够做到这一点之后：
#include <SDL.h>
Hope that works for you.
希望这对你有用。

It's for Xcode 4, but it looks like all the pieces are there.
它适用于 Xcode 4，但看起来所有的部分都在那里。
