OpenCV 2.4.10 - 升级到Xcode 6后，Lipo无法打开输入文件

Question

我一直使用Universal Frameworks超过一年没有问题。我使用Xcode 6和最新的说明创建了新的通用框架。在我尝试将opencv2.framework添加到Link Binary With Libraries之前，所有似乎都工作正常。我的猜测是我需要使用Xcode 6构建的opencv2.framework的更新版本。但我不确定并希望其他人可能有答案。

这是输出：

我还没弄明白如何将opencv包含到我的项目但中，lipo无法打开输入文件的原因是因为它在构建期间没有生成。

我在使用Xcode6的构建脚本时遇到了很多问题。仍在试图弄清楚脚本，环境变量，配置等是否存在问题。

如果有人正在阅读本文并且他们知道如何在Xcode6中创建通用框架（胖静态库），请参阅this question。

谢谢。
