    Might be worth you looking directly at the source code, see if you can get it sorted yourself, and submit a patch.

    Did you try if other environments are affected too? Any linux distribution for example?

    @VRonin what are the other errors of FindNextChangeNotification?didn't find them in the win32 msdn documentation.
    And I don't really know how to do debug of Qt ? because it is in QtCore,so I suppose I must take the project and source of QtCore, but my test project use not only QtCore but QtGui and QtWidget too....

      I'll take a quick look and see if I can spot something in the source, no promises though

        @VRonin Thank you vronin, do you know how I can debug QtCore (or corelib or io) with my test project synchro as executable with QtCreator and mingw-w64(the compiler of qt.io).I suppose I must take the source (single,the .zip) but don't really know how to do that.my project synchro uses core,gui and widget but I suppose I must open corelib or io as project in QtCreator

          @VRonin do you know how to get the version 5.6.2 of qtbase from code.qt.io with git? (to build it in debug and try to debug corelib)

            Just clone the repository and check out the 5.6 branch

                @VRonin it is done.but to debug qfilesystemwatcher should I open corelib.pro in QtCreator (QtCore) and build it debug and put breakpoints and attach to my app synchro ?

                    @VRonin there is "attach to unstarted application" and "debug an external application" in Qtcreator\debug. is it possible to use one this option to debug QtCore (corelib) with my app synchro.exe ?

                      @VRonin when building corelib I have this error ..\corelib\global\qt_pch.h:50:21: fatal error: qglobal.h: No such file or directory
                      #include <qglobal.h>
                      qglobal.h is in the directory but I think I lacks an environment variable ?

                        @VRonin OK I think I have found : I have copied the directory include of the source single (.zip) of 5.6.2 in the direcorty qtbase and I have put in my environment variable INCLUDE the path of directory include and reboot my windows...I think it will be ok

                            It think I will build the whole Qtbase as usually and then open the corelib.pro and put the directory of lib QtCored.dll as build directory and try to debug with my exe (synchro.exe)

                              You have to, qtbase, unlike the other modules, requires that you run configure before building it.

                                @SGaist even after done configure,if I want to debug qtcore (corelib) in Qtcreator,it needs to be build with Qtcreator and I can't build it with Qtcreator (mingw).so I can't debug corelib (qtcore) and I don't know how to do.I have built qtbase with command line but it is unuseful...

                                      You have to build qtbase from the command line. There's a lot of stuff happening during the build phase of qtbase like header generation. Therefore, build it once and then start hacking on it.

                                        @SGaist these problems are only for building with QTCreator.I have no problem to build with command line.but to debug QTCore in QTcreator I must build with QTcreator

                                          @SGaist I have built QTbase with command line without problem.But to debug QtCore with QtCreator I must build it with QtCreator.
