我無法在os上構建couchbase ruby​​ gem x 10.6.8

Question

我的目標是通過構建本機擴展來安裝couchbase ruby​​ gem，但我看起來像是gem和libcouchbase C之間的架構不匹配圖書館。下面是一些背景：

• 我正在從源代碼構建OS X 10.6.8，使用RVM和Ruby 1.9.2-P320
• 我運行OS X 10.6.7和Xcode的3.2.5了直到昨天，但我無法建立libcouchbase本地
• 我那麼這被稱爲安裝釀造，以幫助緩解libcouchbase安裝和釀造告訴我，我需要至少升級到3.2.6的Xcode
• 我下載的是難以捉摸的Xcode 4.2 for Snow Leopard，因爲它超過了2個小於 Xcode 3.2.6的演出，我想我會得到最新版本。
• Xcode不會安裝，因爲我發現的證書錯誤是系統安裝程序中的錯誤的結果，並且修復程序是升級到OS X 10.6.8，然後應用系統更新
• 幾個小時稍後重新啓動，我正在運行OS X 10.6.8並安裝了XCode 4.2，libcouchbase通過brew進行編譯，沒有任何打嗝
• 我現在嘗試安裝couchbase gem，但構建本機擴展失敗。它說，它無法找到libcouchbase即使明確地傳遞庫
• 檢查mkmf.log的位置顯示以下（大膽加着重號，但我可能是錯的問題！

所以，在我看來，問題是，海合會正在尋找/usr/local/lib/libcouchbase.dylib的i386的構建和檢查礦山顯示

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

所以，現在我的問題。這是問題還是紅鯡魚？我是否需要將libcouchbase構建爲i386或通用，或者是寶石方面的問題？我一直在這個系統上構建本地gem擴展多年，沒有問題，包括有時令人討厭的mysql gem，但是現在我已經有了新版本的GCC/Xcode。 rvm發佈說明說，Xcode 4.2只適用於Ruby 1.9.3並打破了很多原生擴展，所以我完全卸載它，然後安裝GCC-10.6.pkg從https://github.com/kennethreitz/osx-gcc-installer/這rvm建議作爲一個工作，但我仍然有相同的問題。這裏是我的BREW --env轉儲：

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

無論是現在，當我已經安裝的Xcode 4.2，我-march設置爲酷睿2。應該是原生而不是？在安裝我最新的osx-gcc工具鏈之後，我通過rvm/JewelryBox從源代碼重建了ruby 1.9.2-p320，以確保它使用相同的標誌。它內置的普及，達爾文和似乎是正確的：

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]" 

我知道這是一個大量的信息，但我只是想徹底與細節，並表明我已經試過幾乎一切。我還應該提到，我已經嘗試了開發人員預覽了gem並結合libcouchbase的開發人員預覽，並且錯誤也是一樣的。我沒有試過的兩件事：

1. 安裝XCode 4.1 for Snow Leopard - 即使理論上支持，Apple不再允許下載此文件。
2. 雪豹安裝的Xcode 3.2.6 - 我試圖避免4GB的下載，但我剛開始它現在可以嘗試今晚稍後

任何幫助是極大的讚賞，特別是如果你已經建立之前的OS X上的couchbase寶石。

Answer 1

我認爲這是一個很好的問題，因爲我記得經歷了一些類似的嘗試嘗試構建寶石的痛苦。不過那是一段時間以前，我沒有文件等方便記住我做了什麼，或者如果我的錯誤看起來像你的。

我知道它不如直接回答，但我認爲你應該能夠在這裏與寶石作者聯繫：https://groups.google.com/forum/#!forum/couchbase或通過Twitter上的@avsej。
