Problem build: "This file was generated using the moc from 4.7.4. It"



  • Hi, I´m studying Qt, specifically I´m trying to connect Arduino with Qt to create a GUI for configure a Arduino board.

    I´m using Firmata library for Arduino and Firmatator library (available in this link: https://github.com/dh1tw/firmatator).

    Well, my problem is in firmatator library. When I build “firmatator_examples.pro”, I get this error:
    …\include\firmatator\moc_fdevice.cpp:14: error: C1189: #error : "This file was generated using the moc from 4.7.4. It"

    I think that the problem is due to in this project there is a copy of “QtSerialPort” pre-built and more old (year 2013) than my installed version of “QtSerialPort”. I suppose that I have to do changes in the file .pro but I don´t know…

    I add code of firmatator_examples.pro:

    QT += core

    QT -= gui

    TARGET = firmatator_examples
    CONFIG += console
    CONFIG -= app_bundle

    TEMPLATE = app

    SOURCES += main.cpp
    include/firmatator/moc_serialport.cpp
    ftest.cpp

    #win32:CONFIG(release, debug|release): LIBS += -L$$PWD/include/firmatator/release/ -lfirmatator
    #else:win32:CONFIG(debug, debug|release): LIBS += -L$$PWD/include/firmatator/debug/ -lfirmatator
    #else:symbian: LIBS += -lfirmatator
    #else:unix: LIBS += -L$$PWD/include/firmatator/ -lfirmatator

    #INCLUDEPATH += $$PWD/include/firmatator
    #DEPENDPATH += $$PWD/include/firmatator

    HEADERS +=
    include/firmatator/firmatator.h
    include/firmatator/fdevice.h
    ftest.h

    win32:CONFIG(release, debug|release): LIBS += -L$$PWD/include/firmatator/release/ -lfirmatator
    else:win32:CONFIG(debug, debug|release): LIBS += -L$$PWD/include/firmatator/debug/ -lfirmatator
    else:symbian: LIBS += -lfirmatator
    else:unix: LIBS += -L$$PWD/include/firmatator/ -lfirmatator

    INCLUDEPATH += $$PWD/include/firmatator
    DEPENDPATH += $$PWD/include/firmatator

    win32:CONFIG(release, debug|release): LIBS += -L$$PWD/include/QSerialDevice/release/ -lSerialPort
    else:win32:CONFIG(debug, debug|release): LIBS += -L$$PWD/include/QSerialDevice/debug/ -lSerialPort
    else:symbian: LIBS += -lSerialPort
    else:unix: LIBS += -L$$PWD/include/QSerialDevice/ -lSerialPort

    INCLUDEPATH += $$PWD/include/QSerialDevice
    DEPENDPATH += $$PWD/include/QSerialDevice

    PD: I have QT 5.4.1 (MSVC 2013 32 bit) with Qt Creator 3.3.1.
    Sorry for my English and I wait replies :-)

    Thanks in advance.

    moc_*.cpp files are usually created during compilation of a Qt project.
    I don't know why they are included in firmatator_build/
    Delete the firmatator_build/ directory and try again.



  • @jsulm Thanks for reply.
    I have tried it and it appears the same error..

    hi
    just to confirm:
    you deleted the old included build folder ?
    https://github.com/dh1tw/firmatator/tree/master/firmatator_build

    moc_fdevice.cpp First upload 3 years ago
    moc_fdevice.o First upload 3 years ago
    moc_serialport.cpp First upload 3 years ago
    moc_serialport.o First upload 3 years ago



  • Yes, exactly. I have done that. Also I tried to delete all files moc*.cpp/o of folder "firmatator_examples_build" and nothing... I do not know what else to do...

    Thanks for reply.

    @BlackSP said:

    generated using the moc from 4.7.4

    It still say that even you are 100% sure you deleted it. ?
    That is very strange.

    To be be sure.
    besides QT 5.4.1, u dont have any 4.X installed?

    Did u also clean your real build folder?
    ( maybe project points to the one we call "old")
    Please check in Project Tab/button.
