c++ - Windows 上的 Qt5 项目与 MinGW

Question

我一直在为 Qt/C++ 项目使用 Visual Studio 2012。

我正在尝试迁移到 MinGW，这样我就可以完全使用 C++11 而不是 MSFT 编译器提供的部分支持。使用 CMake 生成项目并进行得非常顺利，编译了所有子项目和主项目本身。

但是，链接给了我一些错误，我不确定如何解决它们:

该项目使用 Visual Studio(和 Xcode、FWIW)编译和链接得很好，所以我不确定链接器缺少什么。

有人可以提供任何建议吗？

您需要为 MinGW 下载 Qt(或者您自己构建它，如果您使用的 MinGW 版本与构建 Qt 版本的版本不同。)Qt 的 VS 版本不能与 MinGW 一起使用。
