    That's rather odd, because <code>_MCW_EM</code> should "only be used if it is defined":http://qt.gitorious.org/qt/qtbase/blobs/master/src/corelib/tools/qlocale_tools.cpp#line2236 (and it actually is for MinGW-w64 in <code>float.h</code>) - and I can't reproduce it.

    In a first step I would check the environment, especially if there aren't any fragments of a different toolchain including the Windows 8 SDK, which could cause wrong headers to be included. INCLUDE, LIB and LIBPATH should be empty, PATH should contain MinGW.

    If this doesn't help you may file a "bug report":https://bugreports.qt-project.org/ or simply stop by at #qt@freenode or #qt-labs@freenode, probably this is an already known problem.

      Just to make clear the Environment Variables PATH should be clean except MinGW/bin? Not even Perl and Python should be inside it (as the guide say)?

        No, PATH should of course contain all the neccessary tools, but it should not contain other versions of MinGW or the Windows SDK.

          "I've just seen":http://qt-project.org/forums/viewthread/21862/ that you are using a rubenvb build. I've had problems with it in the past and I recommend using a mingw-builds build instead (which will also become the official MinGW build for Qt).

            That what I have in my path now:
            @C:\Python33;C:\Perl64\site\bin;C:\Perl64\bin;C:\MinGW\bin;C:\Program Files (x86)\Programming\Git\cmd;C:\Program Files (x86)\Programming\Git\bin;@

            this is my original path:
            @C:\Python33;C:\Perl64\site\bin;C:\Perl64\bin;C:\Program Files (x86)\AMD APP\bin\x86_64;C:\Program Files (x86)\AMD APP\bin\x86;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0;C:\Program Files (x86)\SystemTools\ATI Technologies\ATI.ACE\Core-Static; C:\Program Files (x86)\Programming\Java\jre7\bin;C:\Program Files (x86)\Programming\Windows Kits\8.0\Windows Performance Toolkit;C:\cygwin\bin;C:\MinGW\bin;C:\Program Files\Microsoft\Web Platform Installer;C:\Program Files (x86)\Microsoft ASP.NET\ASP.NET Web Pages\v1.0;C:\Program Files\Microsoft SQL Server\110\Tools\Binn;C:\Program Files\Programming\doxygen\bin;C:\Program Files (x86)\Programming\Git\cmd;C:\Program Files (x86)\Programming\Git\bin@

            I use this "mingw-builds":http://code.google.com/p/mingw-builds/downloads/list (the first one)

            now I can't even run configure:

              The latest can be found "here":http://sourceforge.net/projects/mingwbuilds/, the project at Goole Code is outdated.

                  A quick search revealed that both, MinGW and GCC, come with a <code>float.h</code>. One having those definitions (which should be picked), one not.

                  So this might be an GCC / MinGW issue, and not directly related to Qt.

                    "Yes I found this as well":https://bugreports.qt-project.org/browse/QTBUG-7576

                    but it's seems to be old and not working...
                    How can I use only MinGW? maybe it other Gcc conflicting!

                      If I change this line

                      _control87(oldbits, _MCW_EM|_MCW_DN|_MCW_RC);

                      in qlocale_tools.cpp to

                      _control87(oldbits, MCW_EM);

                      it's run until I get this error:

                        I used VS2012 command prompt to build "Qt5Sdk":http://qt.gitorious.org/qtsdk and it's work, but it's not recognize #include <QtGui/QApplication>, #include <QFileDialog> and more...it's does recognize #include <QGui>.

                        maybe VS2012 build didn't goes well?
                        I added to PATH “C:\qt5\2012.11\qtbase\bin and C:\qt5\2012.11\qtbase\lib".

                        • BTW in Windows7 where's are the INCLUDE, LIB and LIBPATH, becaise I can see I can set them from Qt, but when entered windows 7 environment variables there is only PATH?

                            Some update:
                            I couldn't able to build qt5 with mingw, but I did succeed doing this with vs2012 command prompt, but since they changed the include trees in qt5, I needed to do a lots of include changes in my project, so I decided not to use qt5. Nevertheless since I wanted good support with c++11, I built qt4.8.x which did succeed with mingw, but c++11 functions like for example stod didn't recognize with it, I was very disappointed, so now I will try build it with vs2012...lets see if this will sort this out!

                              The fixqt4headers.pl script found in qtbase/bin will do that for you.

                                The problem it's not only includes, some objects like QMessageBox, after fixing the includes are still not recognized as well.
