使用MinGW的Windows上的Qt5项目

Question

I have been using Visual Studio 2012 for a Qt/C++ project.

I am trying to migrate over to MinGW so that I can use C++11 entirely instead of the partial support that MSFT's compiler offers. Using CMake to generate the project and making was proceeding very well, compiling all the subprojects and the main project itself.

However, the linking is giving me some errors and I'm not sure how to resolve them:

The project compiles and links just fine using Visual Studio (and Xcode, FWIW), so I'm not sure what the linker is missing.

Can anyone offer any suggestions?

你需要为MinGW下载Qt（或者你自己构建它，如果你使用的是不同版本的MinGW而不是Qt版本的版本。）Qt的VS版本不能与MinGW一起使用。
