Qt Creator with MinGW 'no match for operator' Error

In order to deploy my project in Windows, I have got the Qt project from Linux and paste all the source files one paste on Windows 7 VM VirtualBox and tried to build it there.

Unfortunately, I am having the following error that I can't find a way to fix. The Qt Creator compiles well the example projects that come with it, but with my project, it pops that errors on many Qt files. And sorry, I don't have enough reputation to post images, so I'll let the links
