`#include< iostream>`with`-std = c ++ 0x`断开 [英] `#include <iostream>` with `-std=c++0x` is broken

问题描述

如果我指定 -std = c ++ 0x 到g ++，那么我不能 #include< iostream> 。我收到以下错误消息（在mingw下的g ++ 4.4.0）：

If I specify -std=c++0x to g++, then I can't #include <iostream>. I get the following error messages (g++ 4.4.0 under mingw):

In file included from c:\qt\2010.05\mingw\bin\../lib/gcc/mingw32/4.4.0/include/c++/bits/postypes.h:42,

任何想法为什么？这是否已经修复在最新的g ++？ （如果是，是否有人知道如何将最新的g ++整合到Qt中）

Any ideas why? Has this been fixed in the latest g++? (And if so, does anybody know how to incorporate the latest g++ into Qt?)

推荐答案

它似乎是一个错误。有一个主题有一个简单的补丁（在最后）。

It seems to be a bug. There is a thread with a simple patch (in the very end).
