`的#include <iostream> ```-std = c ++ 0x`被打破了

Question

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

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

c:\qt\2010.05\mingw\bin\../lib/gcc/mingw32/4.4.0/include/c++/cwchar:166: error: '::vswprintf' has not been declared

有什么想法嗎？ 這是在最新的g ++中修復的嗎？ （如果是這樣，有人知道如何將最新的g ++納入Qt嗎？）

Answer 1

這似乎是一個錯誤 。 有一個帶有簡單補丁的線程 （最后）。

Answer 2

if win32{
    QMAKE_CXXFLAGS += -std=gnu++0x
}
else {
    QMAKE_CXXFLAGS += -std=c++0x
}
