如何在 Qt Creator 中启用 C++11?

2021-12-09 00:00:00 qt c++ c++11

标题很自我描述.我已经下载了 Qt Creator 2.7.0,我正在尝试编译一些基本的 C++11 代码:

The title is pretty self-descriptive. I've downloaded Qt Creator 2.7.0, and I am trying to compile some basic C++11 code:

int my_array[5] = {1, 2, 3, 4, 5};
for(int &x : my_array)
{
  x *= 2;
}

我收到以下错误:

range based for loops are not allowed in c++ 98 mode

然而,根据这篇文章 此版本的 Qt Creator 支持 C++11.那么如何启用它?

Yet, according to this article this version of Qt Creator supports C++11. So how do I enable it?

推荐答案

根据本站 添加

CONFIG += c++11

到您的 .pro 文件(参见该网页底部).它需要 Qt 5.

to your .pro file (see at the bottom of that web page). It requires Qt 5.

其他答案,建议

QMAKE_CXXFLAGS += -std=c++11(或 QMAKE_CXXFLAGS += -std=c++0x)

也适用于 Qt 4.8 和 gcc/clang.
