在XCode中获得较旧的SDKROOT行为

问题描述

我正在尝试建立一个用于模拟器或设备构建的库，我看到的所有地方都说明SDKROOT应该扩展为/Developer/Platform/<>/SDKs/<>/，其中将<>填入根据您的项目设置.

I'm trying to setup a library for simulator or device building and everywhere I see explains that SDKROOT should expand to a /Developer/Platform/<>/SDKs/<>/, where <> is filled in by your project settings.

Internet上的许多链接都说明SDKROOT会扩展到某个路径，但是较新版本的XCode SDKROOT会扩展到"iphoneos2.2.1"-几乎没有帮助(对于此任务).

Many links on the internet explain that SDKROOT will expand to a path, but the newer versions of XCode, SDKROOT expands to "iphoneos2.2.1" - which isn't nearly as helpful (for this task).

很显然，如果您查看苹果的文档，其行为就会发生变化:

Clearly enough if you look at apples documentation, the behavior changed:

http://developer.apple.com/mac/library/DOCUMENTATION/DeveloperTools/Reference/XcodeBuildSettingRef/9-Revision-3.1/history.html

我通过查看Mac上的一些较旧的文档来确认更改.

I confirmed the change by looking at some older documentation on my mac.

是否有关于如何在最新的XCode版本中实现类似功能的想法?我的最终目标是以独立于平台的方式链接到静态库.头文件在每个平台上都不同，因此构建一个静态静态库无法解决问题.

Any thoughts on how to achieve similar functionality in the latest XCode builds? My end goal is to link to a static library in platform independent ways. The header files differ on each platform, so building a fat-static library doesn't solve the problem.

推荐答案

在Xcode 3.2.1中，SDK_DIR看起来包含了以前在SDKROOT中的路径.

In Xcode 3.2.1, it looks like SDK_DIR contains the path that used to be in SDKROOT.
