帮助？

Answer 1

Xcode 5.1 的一个主要变化是它包含的 clang 版本不再接受未知/无效参数。您正在尝试构建使用参数 -fsingle-precision-constant 和 -fvariable-expansion-in-unroller 的东西，这些不再合法。

您必须与负责您尝试构建的任何东西的人一起处理这个问题（在这种情况下，显然是称为“nds4ios”的东西）。他们需要创建新的源代码，其构建命令不包含错误参数。

或者，暂时恢复到 Xcode 5.0.2 中的 clang。为此，请安装 Xcode 5.0.2，然后在 Xcode 5.1 中打开 Preferences，切换到 Locations pref 窗格，然后将 Command Line Tools 弹出菜单切换到 Xcode 5.0.2。
