    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:
      C:\qtsrc\qtbase\src\corelib\animation\qabstractanimation_p.h:52:31: fatal error: private/qobject_p.h: No such file or directory
      #include <private/qobject_p.h>
      ^

        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

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

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