フレームワークの構築に苦労しています。
ここから OpenCV のコピーを複製しました: https://github.com/Itseez/opencv
次に、最新のcmake 2.8.10.2があることを確認しました
次に、iOS フォルダーで build_framework.py を実行します。
例えば
./opencv/ios/build_framework.py opencv-ios-build
これからの出力は次のとおりです。

ただし、Xcode プロジェクトをビルドします。
プロセスは引き続きコンパイルを実行しますが、これは opencv コアの rand.cpp で失敗します
