    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

                @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.

                          @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....

                              I have corrected this bug and the other under linux too, my correction is not very clean,but it corrects the bugs.I must look under mac os too
