    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:
        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

                @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.

                        @jsulm yes I have an executable to debug qtcore,but my problem was only because shadow build was checked and it tries to build qtcore.now it is ok

                          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....
