Xcode 4.2 + C ++ 0x/libc ++找不到iostream [英] Xcode 4.2 + c++0x/libc++ cannot find iostream

问题描述

我正在使用Macbook 1g，雪豹.

I'm using Macbook 1g, Snow Leopard.

几天前，我安装了xcode 4.2，并为c ++ 0x创建了一个测试项目.

Few days ago i installed xcode 4.2 and made a test project for c++0x.

我将LLVM 3.0设置为c ++编译器，将C ++语言方言设置为C ++ 0x，将C ++标准库设置为libc ++.

I set LLVM 3.0 as c++ compiler, C++ Language Dialect as C++0x and C++ Standard Library as libc++.

但是在构建时，发生了错误.

but when building, error occured.

"iostream" file not found

我觉得这很令人困惑.我该如何解决这个问题?

I find it most bewildering. How can I solve this problem?

推荐答案

我将libc ++更改为libstdc ++".如何?这个设置在哪里? Apple文档说:仅将构建设置中的"C ++标准库类型"设置为...".构建设置很长，我看不到要设置的地方.谢谢.

"I changed libc++ to libstdc++". How? Where is this setting? Apple documentation says "simply set "C++ Standard Library Type" in the build settings to ... " Build settings is long and I don't see the place to set. Thanks.

编辑-没有什么比小睡可以清醒头脑的了........................................................................

Edit - Nothing like a nap to clear the head.

请确保将实现文件的文件名后缀设为".mm".

Be sure to make the file name suffix of the implementation file to be ".mm".

项目->构建设置-> Apple LLVM编译器3.1-语言->然后: C ++语言方言-> C ++ 11(或其他选项) C ++标准库-> libstdc ++

Project->Build Settings->Apple LLVM compiler 3.1-Language-> Then: C++ Language Dialect->C++11 (or whatever option) C++ Standard Library->libstdc++

别忘了这最后一个！ 将源代码编译为-> Objective-C ++

And don't forget this last one! Compile Sources as->Objective-C++
