如何编程C ++ 11使用Qt5？ [英] How to Program C++11 Using Qt5?
问题描述
我准备好与我的朋友一起编写跨平台项目。我们决定分别使用Qt和gcc作为我们的IDE和工具链。他在Linux上工作，我在Windows上工作。
I'm getting ready to program a cross-platform project with my friend. We decided on using Qt and gcc as our IDE and toolchain respectively. He works on Linux, I work on Windows.
但是，Linux上的gcc不一定是Windows上的gcc。更具体地说，Qt在Windows上安装mingw与gcc 4.4和我的朋友有gcc 4.7。所以我试图得到一个更新的gcc版本的Windows。
However, gcc on Linux isn't necessarily gcc on Windows. More specifically, Qt on Windows installs mingw with gcc 4.4 and my friend has gcc 4.7. So I tried getting a more recent gcc version for windows.
我当前的版本的Qt是5，并使用gcc 4.7从这个网站下载并安装：http://www.equation.com/servlet/equation.cmd?fa=fortran
My current version of Qt is 5 and using gcc 4.7 downloaded and installed from this site: http://www.equation.com/servlet/equation.cmd?fa=fortran
我将它安装在C：\QtSDK\mingw，只需要覆盖从Qt安装存在的所有文件。我想，如果我只是采取短路线，我不会重新配置任何Qt。
I installed it in C:\QtSDK\mingw and simply overrode all the files existing from the Qt installation. I figured that I wouldn't have to reconfigure anything in Qt if I just took the short route.
但是，即使使用编译器标志：
However, even using the compiler flags:
QMAKE_CXXFLAGS += -std=c++0x (Qt 4.7)
和
CONFIG += c++11 (Qt5)
IDE或工具链无法编译一个简单的基于范围的for循环：
the IDE or toolchain fails to compile a simple range-based for loop:
int main(int argc, char *argv[])
{
int my_array[5] = {1, 2, 3, 4, 5};
for (auto x : my_array)
std::cout << x << std::endl;
return 0;
}
或初始化程序列表：
int main(int argc, char *argv[])
{
QVector<int> testsData { 1, 2, 10, 42, 50, 123 };
QStringList options = { QLatin1String("foo"), QLatin1String("bar") };
return 0;
}
然而，查看gcc 4.7的实现细节，和更多 - 应当容易获得。
However, looking at the implementation details of gcc 4.7, both of these features- and more- should be readily available.
有没有人试图在Windows上使用gcc和Qt？如果是，你是如何让它工作？我想要一个解决方案使用gcc 4.6或4.7，但如果不是可能的话，将解决较少。
Has anyone else tried to use gcc and Qt for Windows? If so, how did you get it to work? I would like a solution using gcc 4.6 or 4.7, but will settle for less if it is not at all possible.
或者，有一个开发环境为Linux和Windows使用C ++ 11的功能？如果它只是工作，我还会解决Qt之外的东西...
Alternatively, is there a dev environment for Linux and Windows that makes use of C++11 features? I would also settle for something besides Qt if it just works...

推荐答案
QMAKE_CXXFLAGS += -std=c++0x
导致错误，因为您没有使用MinGW编译器。 D9002：忽略未知选项 -std = c ++ 0x 是MSVC编译器的错误。
Results in an error because you're not using the MinGW compiler. "D9002: Ignoring unknown option -std=c++0x" is an error from the MSVC compiler.
在QtCreator中，转到项目选项卡（左侧），并更改您使用的工具链。如果它没有自动检测MinGW，你将不得不自己添加它通过点击管理按钮。
In QtCreator, go to the projects tab(on the left) and change the toolchain you're using. If it hasn't auto-detected MinGW, you're going to have to add it yourself by clicking on the manage button.
