libv8 3.11.8.3をインストールする際のエラー

Question

OSX 10.9 MavericksとXCode 5.0.1の新規インストールを実行しています。私のプロジェクトでバンドルインストールを実行しようとすると、libv8 gemのインストールに失敗します。出力は次のとおりです。私は

Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1 
Apple LLVM version 5.0 (clang-500.2.79) (based on LLVM 3.3svn) 
Target: x86_64-apple-darwin13.0.0 
Thread model: posix 

を取得しています

gcc -v 

を行うとき

はまた、私は自作経由でGCCをインストールしようとしたが、これは役立ちません。他に可能な解決策は何ですか？

Answer 1

Ok、古いバージョンのXcode（4.6.3）をインストールし、コマンドラインツールのバージョンをXcodeの環境設定で古いものに変更することで問題が解決されました。

Answer 2

アプリケーションフォルダにはXCode 4.6.3をインストールし、あなたはあなたがの古いバージョンに

sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer 

Answer 3

スイッチの操作を実行して戻すことができlibv8インストール完了したら

sudo xcode-select --switch /Applications/Xcode4.6.3.app/Contents/Developer 

を実行しますXcodeは私のためには機能しませんでした。代わりに、githubのlibv8修正を最後に使用しました。https://github.com/cowboyd/libv8/issues/107

これは完全に機能します。
