Xcode 5.1で動作するようにSDL 2.0.2をインストールするために、次の2つのチュートリアル（またはバージョンの違いにより該当する部分）を試してみました。

SDL 2フレームワークがリンクされたプログラムを実行すると、Xcodeがクラッシュし、次の問題の詳細が表示されます。

ディスクユーティリティを使用して権限を修復しようとしましたが、Xcodeのソース管理も無効にしています。 SDLへの参照を削除するだけで問題は解決します。たとえば、次のプログラムは最初は機能しますが、プロジェクトをSDLにリンクするとクラッシュします。

// #include <SDL2/SDL.h> #include <iostream> int main() { std::cout << "Hello World!" << std::endl; return 0; }

ここで何か悪いことをしていますか？

SDL2が適切に署名されていないことが問題のようです。 https://bugzilla.libsdl.org/show_bug.cgi?id=2058 に問題を修正するためのチケットがあります。

Lldbを使用してXcode 5からアプリケーションを起動すると、Xcodeは、アプリケーションがロードするモジュールを検査するプラグインをロードします。これは、おそらくプログラムの洞察を得るためです。 Xcodeは、無効な署名に裏打ちされたページから読み取るとクラッシュするように設定されています。 SDL2は適切に署名されていないため、Xcode 5がSDL2ライブラリを調べようとすると、無効なページから読み取られてクラッシュします。上記のクラッシュレポートの次の行によって、これが起こっているという手がかりが得られます。

Exception Type: EXC_BAD_ACCESS (Code Signature Invalid)

SDLが適切に署名されていないことを確認するには、SDL2が存在するフォルダーから次のコマンドを実行します。

$ codesign -vvvv SDL2 SDL2: invalid signature (code or signature have been modified) In architecture: x86_64

独自のバージョンのSDL2（上記のソリューション）を構築したくない場合は、署名を更新して正しいものにすることができます。

$ codesign -f -s - SDL2 SDL2: replacing existing signature

そして、新しい署名が正しいことを確認するには：

$ codesign -vvvv SDL2 SDL2: valid on disk SDL2: satisfies its Designated Requirement

署名が無効である理由がわからないため、これを回避策として実行することはセキュリティの観点から危険であることに注意してください。

2.0.2（安定版）を使用しても同じ問題が発生しました。私は最新のコード（3/13現在）をダウンロードして、手動でフレームワークをコンパイルし、それが機能しました。
