如果我使用Haskell平台（2013.2.0.0）与GHC（7.6.3）是否可以安装Xcode 5？
[英]If I am using Haskell Platform (2013.2.0.0) with GHC (7.6.3) is it okay to install Xcode 5?
问题描述
I currently have Xcode 4.6.3 installed. 
我目前安装了Xcode 4.6.3。 Today the App Store told me that Xcode 5 is available. 今天App Store告诉我Xcode 5可用。
Should I upgrade, or will the upgrade break GHC 7.6.3? 我应该升级，还是升级会破坏GHC 7.6.3？
I am looking at ghc trac #8197 and ghc trac #8148 , and they seem to suggest that there will be problems. 我在看ghc trac＃8197和ghc trac＃8148 ，他们似乎暗示会有问题。 Is that correct? 那是对的吗？

No it is not. 不它不是。
Upgrading to Xcode 5 will break a whole mess of things. 升级到Xcode 5将打破一堆乱七八糟的东西。 (A common one is Cabal installs) （常见的是Cabal安装）
GHC 7.6.x does not now how to use clang for a preprocessing step and it will break. GHC 7.6.x现在没有如何使用clang进行预处理步骤，它会破坏。
Do not upgrade to Xcode 5 until GHC 7.8 is released. 在GHC 7.8发布之前，请勿升级到Xcode 5。
I did this before I started learning haskell and it was not a fun experience trying to figure out what went wrong when I tried to download cabal packages and ghc generated a 4000 line error code. 在我开始学习haskell之前，我做到了这一点，当我尝试下载cabal包并且ghc生成了4000行错误代码时，试图弄清楚出了什么问题并不是一种有趣的体验。

If anyone who has already downloaded Xcode 5 stumbles upon this after everything breaks, the way to fix your bug is: 如果任何已经下载Xcode 5的人在一切都中断后会发现这一点，那么修复bug的方法是：
- Download the Xcode 4.6.x command line tools from the apple developer website. 从Apple开发人员网站下载Xcode 4.6.x命令行工具。
- Install 安装
- Write some killer Haskell 写一些杀手Haskell
