我无法在os上构建couchbase ruby​​ gem x 10.6.8

Question

我的目标是通过构建本机扩展来安装couchbase ruby​​ gem，但我看起来像是gem和libcouchbase C之间的架构不匹配图书馆。下面是一些背景：

• 我正在从源代码构建OS X 10.6.8，使用RVM和Ruby 1.9.2-P320
• 我运行OS X 10.6.7和Xcode的3.2.5了直到昨天，但我无法建立libcouchbase本地
• 我那么这被称为安装酿造，以帮助缓解libcouchbase安装和酿造告诉我，我需要至少升级到3.2.6的Xcode
• 我下载的是难以捉摸的Xcode 4.2 for Snow Leopard，因为它超过了2个小于 Xcode 3.2.6的演出，我想我会得到最新版本。
• Xcode不会安装，因为我发现的证书错误是系统安装程序中的错误的结果，并且修复程序是升级到OS X 10.6.8，然后应用系统更新
• 几个小时稍后重新启动，我正在运行OS X 10.6.8并安装了XCode 4.2，libcouchbase通过brew进行编译，没有任何打嗝
• 我现在尝试安装couchbase gem，但构建本机扩展失败。它说，它无法找到libcouchbase即使明确地传递库
• 检查mkmf.log的位置显示以下（大胆加着重号，但我可能是错的问题！

所以，在我看来，问题是，海合会正在寻找/usr/local/lib/libcouchbase.dylib的i386的构建和检查矿山显示

/usr/local/lib/libcouchbase.dylib: Mach-O 64-bit dynamically linked shared library x86_64

所以，现在我的问题。这是问题还是红鲱鱼？我是否需要将libcouchbase构建为i386或通用，或者是宝石方面的问题？我一直在这个系统上构建本地gem扩展多年，没有问题，包括有时令人讨厌的mysql gem，但是现在我已经有了新版本的GCC/Xcode。 rvm发布说明说，Xcode 4.2只适用于Ruby 1.9.3并打破了很多原生扩展，所以我完全卸载它，然后安装GCC-10.6.pkg从https://github.com/kennethreitz/osx-gcc-installer/这rvm建议作为一个工作，但我仍然有相同的问题。这里是我的BREW --env转储：

CC: /usr/bin/llvm-gcc => /usr/llvm-gcc-4.2/bin/llvm-gcc-4.2

CXX: /usr/bin/llvm-g++ => /usr/llvm-gcc-4.2/bin/llvm-g++-4.2

LD: /usr/bin/llvm-gcc => /usr/llvm-gcc-4.2/bin/llvm-gcc-4.2

CFLAGS: -Os -w -pipe -march=core2 -msse4.1 -mmacosx-version-min=10.6

CXXFLAGS: -Os -w -pipe -march=core2 -msse4.1 -mmacosx-version-min=10.6

CPPFLAGS: -isystem /usr/local/include

LDFLAGS: -L/usr/local/lib

MACOSX_DEPLOYMENT_TARGET: 10.6

MAKEFLAGS: -j2

无论是现在，当我已经安装的Xcode 4.2，我-march设置为酷睿2。应该是原生而不是？在安装我最新的osx-gcc工具链之后，我通过rvm/JewelryBox从源代码重建了ruby 1.9.2-p320，以确保它使用相同的标志。它内置的普及，达尔文和似乎是正确的：

interpreter: "ruby" 
version:  "1.9.2p320" 
date:   "2012-04-20" 
platform:  "universal.x86_64-darwin10.8.0" 
patchlevel: "2012-04-20 revision 35421" 
full_version: "ruby 1.9.2p320 (2012-04-20 revision 35421) [universal.x86_64-darwin10.8.0]" 

我知道这是一个大量的信息，但我只是想彻底与细节，并表明我已经试过几乎一切。我还应该提到，我已经尝试了开发人员预览了gem并结合libcouchbase的开发人员预览，并且错误也是一样的。我没有试过的两件事：

1. 安装XCode 4.1 for Snow Leopard - 即使理论上支持，Apple不再允许下载此文件。
2. 雪豹安装的Xcode 3.2.6 - 我试图避免4GB的下载，但我刚开始它现在可以尝试今晚稍后

任何帮助是极大的赞赏，特别是如果你已经建立之前的OS X上的couchbase宝石。

Answer 1

我认为这是一个很好的问题，因为我记得经历了一些类似的尝试尝试构建宝石的痛苦。不过那是一段时间以前，我没有文件等方便记住我做了什么，或者如果我的错误看起来像你的。

我知道它不如直接回答，但我认为你应该能够在这里与宝石作者联系：https://groups.google.com/forum/#!forum/couchbase或通过Twitter上的@avsej。
