适用于arm64 iPhone的Xcode 5编译失败

Question

我现在正在使用xcode 5为iPhone构建一个C ++库。当我构建“ armv7”，“ armv7s”和“ i386”体系结构时，一切都很好。 但是，当我要构建“ arm64”的体系结构时，我有：

 C++ Compiler:                CMAKE_CXX_COMPILER-NOTFOUND  (ver 5.1.0)

似乎找不到c ++编译器。 顺便说一句，我现在正在使用cmake工具链来构建库，并且更详细的错误消息如下：

-- Setting up iPhoneOS toolchain

有任何想法吗？ 谢谢。

Answer 1

您如何设置目标架构？ 如果在CMAKE_CXX_FLAGS中指定它们，请尝试改用CMAKE_OSX_ARCHITECTURES。

有什么理由不使用Xcode 6和CMake 3+？
