xcode 5 为 arm64 编译 iPhone 失败

Question

我现在正在用 xcode 为 iPhone 构建一个 C++ 库 5. 当我构建架构 "armv7"、"armv7s" 和 "i386" 时，一切很好。但是当我想为 "arm64" 的架构构建时，我有：

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

好像找不到c++编译器。对了，我现在是用cmake toolchain建库，更详细的报错信息如下：

-- Setting up iPhoneOS toolchain
-- iPhoneOS toolchain loaded
-- The CXX compiler identification is Clang 5.1.0
-- The C compiler identification is Clang 5.1.0

有什么想法吗？谢谢。

Answer 1

您如何设置目标架构？如果您在 CMAKE_CXX_FLAGS 中指定它们，请尝试使用 CMAKE_OSX_ARCHITECTURES。

有什么理由不使用 Xcode 6 和 CMake 3+？
