      @Tanuja Can you clean your build and run qmake?

      For more information please re-read.

      Kind Regards,

          @Tanuja said in Build fails as ui_mainwindow.h not found:

          main window.cpp
          HEADERS += main window.h
          FORMS += main window.ui

          Are those file names correct? You have spaces in them?

              @Tanuja In the .pro file your file names have spaces. Please make sure that they reflect real file names.

                QT. += core GUI
                

                should be

                QT += core gui
                

                And as @artwaw said: rerun qmake and rebuild.

                  Apart from previous posts, looks like you changed the UI file name.
                  FORMS += main window.ui

                  I'm seeing blank space between main and window.ui. Is it mainwindow.ui or window.ui ? If it is window.ui,it must be generating ui_window.h file. Please check that. So you must include the ui_windows.h instead of ui_mainwindow.h

                        This looks ok. Do you have the problem still ? Can you create a new project with all default settings in your QtCreator & check everything works ?

                          Yes I created a new project but the problem is still coming. Also there was Qt5cored.dll file which was missing. I added that also.
                          Is this problem because of that?

                            Ok. I suspect that issue with your installation. One last check b4 u get into further. I'm assuiming that you are working on windows system. Do you see uic.exe executable in bin directory of your installation ?

                                    @Tanuja What is the issue with Qt5core.dll?
                                    You could try to install the latest Qt version (5.9.1).

                                        as @jsulm already suggested, you better install the new version and try. My suspect is that you have installed some other software which has old Qt library in path. This must be causing the issue.

                                          as @jsulm already suggested, you better install the new version and try. My suspect is that you have installed some other software which has old Qt library in path. This must be causing the issue.
