Few days ago i installed xcode 4.2 and made a test project for c++0x.
几天前我安装了 xcode 4.2 并为 c++0x 做了一个测试项目。
I set LLVM 3.0 as c++ compiler, C++ Language Dialect as C++0x and C++ Standard Library as libc++.
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++。
but when building, error occured.
但是在构建时，发生了错误。
"iostream" file not found
I find it most bewildering. How can I solve this problem?
我觉得它最令人困惑。我怎么解决这个问题？

"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.
“我将 libc++ 更改为 libstdc++”。如何？这个设置在哪里？Apple 文档说“只需在构建设置中将“C++ 标准库类型”设置为...“构建设置很长，我看不到设置的位置。谢谢。
Edit - Nothing like a nap to clear the head.

Be sure to make the file name suffix of the implementation file to be ".mm".
务必使实现文件的文件名后缀为“.mm”。
Project->Build Settings->Apple LLVM compiler 3.1-Language-> Then: C++ Language Dialect->C++11 (or whatever option) C++ Standard Library->libstdc++
Project->Build Settings->Apple LLVM compiler 3.1-Language-> Then: C++ Language Dialect->C++11 (or any option) C++ Standard Library->libstdc++
And don't forget this last one! Compile Sources as->Objective-C++
别忘了最后一个！将源编译为->Objective-C++

来自评论：
Oh, i found it. libc++ as standard library requires OS X Lion! (...) I changed libc++ to libstdc++ and it compiled successfully.
哦，我找到了。libc++ 作为标准库需要 OS X Lion！(...) 我将 libc++ 更改为 libstdc++ 并成功编译。
