Adding QMAKE_CXXFLAGS += -std=c++0x to Pro file make c++ - Internal compiler error : segmentation fault

"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).

[GoldenAxe]

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:

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The latest can be found "here":http://sourceforge.net/projects/mingwbuilds/, the project at Goole Code is outdated.

[GoldenAxe]

OK configure work fine with the link you gave me.

but we back to square one:

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.

[GoldenAxe]

"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!

[GoldenAxe]

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:

c:/mingw/bin/../lib/gcc/x86_64-w64-mingw32/4.7.2/../../../../x86_64-w64-mingw32/bin/ld.exe: cannot find -lQt5Cored0
collect2.exe: error: ld returned 1 exit status

[GoldenAxe]

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!

[lgeyer]

[quote author="GoldenAxe" date="1352965521"]... I needed to do a lots of include changes in my project.[/quote]

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

[GoldenAxe]

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