XCode 4相对#include搜索中的路径？ [英] XCode 4 Relative #include paths in search?

问题描述

我试图移植一个项目，我最初写在Windows到OS X和我有一些困难的标题搜索路径。

I'm trying to port over a project I initially wrote in Windows to OS X and am having some difficulty with the header search paths.

用户搜索路径以包含源文件夹project / src / core /
在核心下，我有例如：
projects / src / core / sys / sys_sdl.h
尝试包括
projects / src / core / render / opengl_render .h
与指令：

I've used user search paths to include by source folder "project/src/core/" Under core, I have, for example: "projects/src/core/sys/sys_sdl.h" which tries to include "projects/src/core/render/opengl_render.h" with the directive:

#include "render/opengl_render.h"

我尝试了大量不同的选项，但我不能得到Xcode找到该文件，除非我将其更改为../ render / opengl_render.h

I've tried tons of different options, but I can't get seem to get Xcode to find the file unless I change it to "../render/opengl_render.h"

推荐答案

您尝试设置了用户标题搜索路径 $ SRCROOT /..？ $ SRCROOT是包含目标的源文件的目录，所以$ SRCROOT / ..应该是上面的目录，我认为是你想要的。

Did you try setting the User Header Search Path to $SRCROOT/..? $SRCROOT is the directory that contains the target's source files, so $SRCROOT/.. should be the directory above that, which I think is what you want.

问题（如何在Xcode项目中打印构建设置列表？）显示了一个有用的命令容易看到所有的构建设置和他们修改的变量：

A related question (How do I print a list of "Build Settings" in Xcode project?) shows a useful command that makes it easy to see all the build settings and the variables they modify:

$ xcodebuild -project myProj.xcodeproj -target "myTarg" -showBuildSettings
