      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...

            What problem do you get building from the command line ?

              @SGaist I have added INCLUDEPATH +="../../include"
              INCLUDEPATH +="../../include/QtCore"
              in the corelib.pro because I had errors on include paths but I have still errors on other include paths:
              In file included from C:\qtsrc\qtbase\src\corelib\animation\qabstractanimation.cpp:143:0:

                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

                      @stephane78 Your assumption is wrong: you don't have to build with QtCreator to be able to debug in QtCreator. You just need to build a debug version.

                          @stephane78 To debug QtBase you need a project which is linked against it - you cannot execute a library, so you need an executable. Create a project write some code which uses QtBase, put a break point and start debugging. You then can step into QtBase code.

                                OK I have found a solution for windows to this bug (see :https://bugreports.qt.io/browse/QTBUG-59616). I have uploaded here the two files qfilesystemwatcher_win_p.h and qfilesystemwtacher_win.cpp that correct it.
                                I will search a solution for linux and for macos if there is the problem on mac os too....
