问题描述

限时删除!!

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++
