【问题描述】：

我在 Mavericks 上安装 gem motion-cocoapods 时遇到问题。我正在使用 ruby 1.9.3-p484、OS X Mavericks、Xcode 5.1。

我找到了很多解决方案，但没有一个有效。

这是我尝试安装时的错误日志

checking for -std=c99 option to compiler... yes
checking for CoreFoundation... no
checking for main() in -lCoreFoundation... no
CoreFoundation is needed to build the Xcodeproj C extension.
*** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers.  Check the mkmf.log file for more
details.  You may need configuration options.

--------------------

这是我尝试过的一些解决方案

重新安装 Xcode 并指向它

xcode-select -p
/Applications/Xcode.app/Contents/Developer

运行以下命令 (command line tools for new 10.9 OSX for ruby gems?)

sudo ln -s /usr/bin/gcc /usr/bin/gcc-4.2

运行此命令 (https://github.com/CocoaPods/CocoaPods/issues/192)

CFLAGS="-F /System/Library/Frameworks" gem install motion-cocoapods -- --with-ldflags="-F/System/Library/Frameworks"

【问题讨论】：

把mkmf.log文件的相关内容贴出来怎么样？
你试过xcode-select --install 吗？
我已经尝试过了，但我收到了以下错误can't install the software because it is not currently available from the software update server.。我找到了解决这个问题的方法，并从苹果开发者网站developer.apple.com/downloads/index.action?name=for%20Xcode%20- 单独下载了 xcode 命令行工具。我仍然遇到同样的错误
我认为以下错误：cc1: error: argument to '-O' should be a non-negative integer 指的是-ObjC 标志。我不是 gcc 极客，所以我无法做出任何详细的推测。但是，我确实相信（直觉）这是命令行工具在某种程度上是错误的。抱歉，我不能更具体。

【解决方案1】：

我在 Mac OS 10.9、rvm 1.25.22、ruby-1.9.3-p484 上遇到了相同的症状，同时尝试运行 gem install cocoapods；问题是我同时安装了 gcc-4.6 和 gcc-4.2。

RVM 显然决定在我安装 ruby 时自动为我运行 brew install gcc46：

$ rvm install 1.9.3-p484
Checking requirements for osx.
Error: No available formula for gcc46 
Installing requirements for osx.
Updating system....
Installing required custom packages: homebrew/versions.
Installing required packages: gcc46...

我的 mkmf.log（和你的一样）显示编译使用 gcc-4.6 并且失败。我的解决方法是 brew uninstall gcc46、rvm uninstall 1.9.3-p484，然后是 brew install apple-gcc42 和 rvm install 1.9.3-p484。

使用从 apple-gcc42 构建的新 ruby，并且在我的系统上没有留下任何 gcc46 痕迹，gem install cocoapods 工作。无需其他卸载或重新安装。
