    Default Qt failing to compile claiming "fatal error: QObject: No such file or directory"

    Hi!

    I have a project developed in Qt 4.8 for Embedded Linux and Linux that compiles fine. Now I'm trying to compile it in Qt 5.5.1 in Windows 7 and I got a problem I'm being unable to solve: each time I try to compile it, I get the error

    Qt Code: 
    1. C:\Qt\Qt5.5\5.5\mingw492_32\bin\uic.exe interface\dialogs\alphanumerickeyboard.ui -o build\uis\ui_alphanumerickeyboard.h
    2. g++ -pipe -fno-keep-inline-dllexport -g -frtti -Wall -Wextra -fexceptions -mthreads -DUNICODE -DV_SERGIPETECH_0=0x100 -DV_SERGIPETECH_1=0x101 -DV_UNILA_0=0x110 -DGENERAL_VERSION_NUMBER=V_UNILA_0 -DAPP_VERSION=\"\" -DMAIN_CLOCK=1000 -DSCREENSAVER_SIMPLE_MODE -DCENTER_CONTROLLER -DPERIODIC_WIDGETS_UPDATE -DSAVE_ENTIRE_PQ -DDEFAULT_THEME_PATH='"D:/Desenvolvimento/RE8000SW/src/trunk/main_projects/interface/re8k_interface/../../..\main_projects\interface\theme"' -DDEFAULT_DATA_PATH='"D:/Desenvolvimento/RE8000SW/src/trunk/main_projects/interface/re8k_interface/../../..\main_projects\interface\data"' -DDEFAULT_TRANSLATION_PATH='"D:/Desenvolvimento/RE8000SW/src/trunk/main_projects/interface/re8k_interface/../../../main_projects/interface/translations"' -DDEFAULT_SCREENSHOT_PATH='"C:\Users\Administrador\Imagens\screenshots"' -DDEFAULT_RECORD_DIR='"C:\Users\Administrador\Documentos\TEMP\LogsRE8000"' -DDEFAULT_PENDRIVE_DIR='"C:\Users\Administrador\Documentos\TEMP\PendriveRE8000"' -DDEFAULT_VERSION_FILE_PATH='"C:\Users\Administrador\Documentos\TEMP\version.info"' -DCALIBRATION_FILE='"C:\Users\Administrador\Documentos\TEMP\caltouchpoints"' -DDEFAULT_ETC_PATH='"C:\Users\Administrador\Documentos\TEMP"' -DDESKTOP -DQT_WIDGETS_LIB -DQT_GUI_LIB -DQT_XML_LIB -DQT_NETWORK_LIB -DQT_CORE_LIB -DQT_NEEDS_QMAIN    qtextension/qcycleimagebutton.cpp   -o qtextension/QCycleImageButton
    3. In file included from qtextension/qcycleimagebutton.cpp:1:0:
    4. qtextension/qcycleimagebutton.hpp:4:19: fatal error: QObject: No such file or directory
    5.  #include <QObject>
    6.                    ^
    7. compilation terminated.
    To copy to clipboard, switch view to plain text mode 

    for the same file, which starts as such:

    Qt Code: 
    1. #ifndef QCYCLEIMAGEBUTTON_H_
    2. #define QCYCLEIMAGEBUTTON_H_
    3.  
    4. #include <QObject>
    5. #include <QAbstractButton>
    6. #ifdef DESKTOP
    7. #include <QtDesigner/QDesignerExportWidget>
    8. #else
    9. #define QDESIGNER_WIDGET_EXPORT
    10. #endif
    11.  
    12. #include "interfaceglobal.hpp"
    13.  
    14. class QLabel;
    15. class QImageButtonIllustration;
    16. class QImageSliderIllustration;
    17.  
    18. typedef qint32 button_id;
    19.  
    20. class QDESIGNER_WIDGET_EXPORT QCycleImageButton : public QAbstractButton
    21. {
    22. 	Q_OBJECT

    I can assure the Qt installation went OK since I created a QWidgets project and it compiled fine. I also checked if there was anything special in the Projects configuration but I couldn't find any problems there.

    I also tried to find solutions to this problem on the web, but nothing helpful was found. Here is my .pro file as for now (minus the .hpp and .cpp includes):

    Qt Code: 
    1. QT      += core gui xml network

    Any help appreciated.
