    I have a complex Qt program with many subclasses referenced as class variables in the qMainWindow. It started with early versions of Qt 5.

    Unfortunately, after about Qt 5.5 or 5.6, qOverload gets involved and I have to up the compiler to c++14. (That may not be a real issue, but it is an annoyance when I am trying to build for previous platforms, and yet work on current platforms.)

    During this process, I found that you cannot include class headers in your mainwindow.h file, as that causes a "redefinition of 'struct QMetaTypeId2<int>" in qobject.h, qmetatype.h. Apparently, the Qt fencing is not operating well with the later compiler versions. I suspect compiler fencing is mostly broken. Even #pragma once seems to fail.

    A solution that worked until moc_mainwindow.cpp is compiled is to not include any header files in mainwindow.h, but only in the CPP files. I can live with that, but it is messy.

    The issue I am having now is that the automatically generated moc_mainwindow.cpp includes mainwindow.h header file first. The moc...cpp compile fails. So, if I start including headers using my own fencing inside the mainwinow.h, the rest of the system still compiles, but the moc_mainwindow.cpp file fails to compile due to the redefinition.

    I was hoping to eventually spawn other "mainwindows" which is why I want class variables that are classes (and not pointers to classes).

    Is there any solution other than a pointer to a class in the mainwindow.h with a forward class definition?

    I can make that work, but it will require a lot of rewriting, which I am not really happy to do with a system that easily compiled under previous versions of Qt.

    Any suggestions are welcome!

    for TLDR; 1) 0 is no longer honored by compilers to follow K&R white book rules, and 2) c++11 has problems with qObject, after Qt 5.12 (or maybe 5.5.1). However, c++14 fixes that error.

    OK. Thanks to your request, I narrowed it down. 0 is forbidden in modern c compilers as a universally cast item, even though it breaks K&R's statement that 0 is automatically cast to anything. The white book should be canceled now.

    #ifndef nullptr
#define nullptr 0
#endif

    Defining this before

    #include <QMainWindow>

    in a blank Qt project breaks the entire project with the error (apparently ignoring fences):

    /usr/include/x86_64-linux-gnu/qt5/QtCore/qmetatype.h:2277:1: error redefinition of ‘struct QMetaTypeId2<int>’
 QT_FOR_EACH_STATIC_TYPE(Q_DECLARE_BUILTIN_METATYPE)

    Removing that define fixes that compiler error, introducing another error.

    So, commenting out that define causes the following problem, but only for c++11:

    /mnt/hgfs/Dropbox/bible/CWP-Desktop-QT/src/CWP/ui_dialogaddtopic.h:55:82: error: ‘qOverload’ was not declared in this scope
         QObject::connect(buttonBox, &QDialogButtonBox::accepted, DialogAddTopic, qOverload<>(&QDialog::accept));
                                                                                  ^~~~~~~~~
/mnt/hgfs/Dropbox/bible/CWP-Desktop-QT/src/CWP/ui_dialogaddtopic.h:55:82: note: suggested alternative: ‘QOverload’

    changing the compiler to c++14 fixes that problem.

    So, either there is a cascade for c++11 compiler tech (your comment notwithstanding) that causes everything to break in Qt 5.12, or the compiler writers have to be notified.

    I was stupid in that I tried to fix a (complained about in previous forums) header file problem in a previous version Qt for (now) unsupported versions of Qt, using a nullptr define. The resulting compile was a cascading "something" that using a 0 caused. It acts like fencing broke, but I don't see why. However, it did lead me far away from the original source of the error, because it was working in earlier versions of Qt.

    The END RESULT is I have learned to NEVER do Qt includes in my Qt header files. Only do simple includes which never reference any Qt headers. Qt is extremely sensitive to compiler versioning, and that changes between minor dot releases.
    Also K&R white book appears to be only a suggestion to compiler writers.

    My true idiocy was believing K&R still held. Everything is changing too fast for me to keep up. I'm too old and too stupid.

    oh, well. problem solved for now.

    Thanks! Your insistence helped!

    I don't have such problems with including Qt headers somewhere - please provide a minimal, compilable example of your issue.

    hmm. That may be a problem. It is a large system and only started having issues when later versions of Qt required more that c++11. Here is a dump of the compile message output, followed by mainwindow.h and moc_mainwindow.cpp, Multi-core multi-thread compile under Lubuntu.

    This is not a simple, compilable example... please strip it down to a bare minimum and also format your code with the code - tag.

    @wsma said in redefinition of 'struct QMetaTypeId2<int> in moc_mainwindow.cpp:

    Unfortunately, after about Qt 5.5 or 5.6, qOverload gets involved and I have to up the compiler to c++14.

    You didn't have to. You can use QOverload<T...>::of() with C++11.

    Here is a dump of the compile message output, followed by mainwindow.h and moc_mainwindow.cpp

    That doesn't help us to reproduce the problem, unfortunately.

    As @Christian-Ehrlicher said, a minimal, compilable example is your best bet at getting a solution.

    for TLDR; 1) 0 is no longer honored by compilers to follow K&R white book rules, and 2) c++11 has problems with qObject, after Qt 5.12 (or maybe 5.5.1). However, c++14 fixes that error.

    OK. Thanks to your request, I narrowed it down. 0 is forbidden in modern c compilers as a universally cast item, even though it breaks K&R's statement that 0 is automatically cast to anything. The white book should be canceled now.

    #ifndef nullptr
#define nullptr 0
#endif

    Defining this before

    #include <QMainWindow>

    in a blank Qt project breaks the entire project with the error (apparently ignoring fences):

    /usr/include/x86_64-linux-gnu/qt5/QtCore/qmetatype.h:2277:1: error redefinition of ‘struct QMetaTypeId2<int>’
 QT_FOR_EACH_STATIC_TYPE(Q_DECLARE_BUILTIN_METATYPE)

    Removing that define fixes that compiler error, introducing another error.

    So, commenting out that define causes the following problem, but only for c++11:

    /mnt/hgfs/Dropbox/bible/CWP-Desktop-QT/src/CWP/ui_dialogaddtopic.h:55:82: error: ‘qOverload’ was not declared in this scope
         QObject::connect(buttonBox, &QDialogButtonBox::accepted, DialogAddTopic, qOverload<>(&QDialog::accept));
                                                                                  ^~~~~~~~~
/mnt/hgfs/Dropbox/bible/CWP-Desktop-QT/src/CWP/ui_dialogaddtopic.h:55:82: note: suggested alternative: ‘QOverload’

    changing the compiler to c++14 fixes that problem.

    So, either there is a cascade for c++11 compiler tech (your comment notwithstanding) that causes everything to break in Qt 5.12, or the compiler writers have to be notified.

    I was stupid in that I tried to fix a (complained about in previous forums) header file problem in a previous version Qt for (now) unsupported versions of Qt, using a nullptr define. The resulting compile was a cascading "something" that using a 0 caused. It acts like fencing broke, but I don't see why. However, it did lead me far away from the original source of the error, because it was working in earlier versions of Qt.

    The END RESULT is I have learned to NEVER do Qt includes in my Qt header files. Only do simple includes which never reference any Qt headers. Qt is extremely sensitive to compiler versioning, and that changes between minor dot releases.
    Also K&R white book appears to be only a suggestion to compiler writers.

    My true idiocy was believing K&R still held. Everything is changing too fast for me to keep up. I'm too old and too stupid.

    oh, well. problem solved for now.

    Thanks! Your insistence helped!

    I loved "K&R C". But not all of it has held for a long time for C++....

    @JonB I agree. However, 0 as universally cast has held until very recently. This is the first time that 0 has failed me. Also, the "redefinition" error should not have occurred, since it was the exact same file that was flagged as redefining it. It was already fenced. So, either fencing broke, or that is one unusual macro that the compiler just did not handle right.

    For instance, certain versions of the gcc compiler do have a problem with calling const void functions from an array. It appears to be a hard coded patch rather than a specifically crafted warning. To silence it, I had to do the following: (a pragma for silencing that specific warning did not work, nor did a specific -Wno-... work from the command line.)

    //=============================================================
// silence warning about calling const void function.  
// (gcc has a hardcoded patch
// for the const void function that only responds to shutting 
// down all warnings)
  //=============================================================

    #pragma GCC diagnostic push
#pragma GCC diagnostic warning "-w"

    return (PRead[PinID])();

    //============================================================
#pragma GCC diagnostic pop
//============================================================

    
I realize that the function is void.  I realize I am breaking rules (this is embedded)
The warning was for *calling* the const void function.  Not a warning about using a return from it (which in theory does not exist). 
 I was expecting the warning on using a return from a const void function.  

BTW, it does work.  The compiler template calls for the return to be in the 
accumulator, and the accumulator is passed forward.  Bad coding, yes. 
 Compiler warning is interesting, though.

So, compiler writers have hiccuped in the past, and are probably doing it again.....

    @wsma
    Did you at least test compiling (PRead[PinID])() on its own, to be sure? Without removing the return I would expect any compiler to error, including C ones.

    Plus ca change. Takes me back to a bug I remember still from System V.0(!!) C compiler. It had support for void (just, and I don't recall K&R1 even having that), but I had a big array of (void)() functions and it barfed on having an array of them. Sound familiar? ;-) Had to #define voidfunc int and go through all the functions changing them to voidfunc foo() and make them return some int, so they "looked" void to me but had to return int to have the function put into an array!

    Not true. Qt 5.7.0 made C++11 compulsory; Qt 6.0.0 made C++17 compulsory. No C++ version bumps were required for any other Qt version.

    nullptr being undefined means that you have not enabled C++11 in your project/compiler. Therefore, the appropriate fix was to simply enable C++11.

    Please remove all #define's that "clash" with C++11.
