Can't compile Qt 4.8.7



  • Hi

    I need to compile Qt 4.8.7 on my Linux Stretch 64bit.
    I have configure option:

    OPENSSL_LIBS='-L/usr/local/lib -lssl -lcrypto' ./configure -I/usr/local/include -platform linux-g++-64 -fast -opensource -confirm-license -prefix /home/franki/Qt/4.8/  -openssl-linked -no-webkit -no-qt3support -no-script -no-scripttools -nomake demos -nomake examples
    

    but it ends up with error for which I don't know what to do:

    Does anybody know how to make it work?

  • The problem is:

    itemviews.cpp: In member function ‘virtual bool QAccessibleTable2::unselectColumn(int)’:
    itemviews.cpp:396:105: error: conversion from ‘int’ to ‘QItemSelectionModel::SelectionFlags {aka QFlags<QItemSelectionModel::SelectionFlag>}’ is ambiguous
         view()->selectionModel()->select(index, QItemSelectionModel::Columns & QItemSelectionModel::Deselect);
    

    The problem here is, the code is trying to convert int into a Qt type, which is ambiguous, even if this type inherits int. (IDK).

    Try 4.8.6, which is the latest official 4.8 version I am able to find.



  • exactly the same error in qt 4.8.6
    Is it something with gcc? some flag?

    Hi,

    What exact version of GCC are you using ?

    @nestorac Qt 4.8.7 is the latest and last official version released of the Qt 4 series.



  • gcc -v

  • Hi,

    Any hints about why I can't compile 4.8 Qt on Linux x64 ?
    This must be something with gcc version or some kind of flag ???

    Best Regards
    Marek


  • Lifetime Qt Champion

    This version of GCC doesn't allow the conversion from QFlags to int, so just add a static cast and you'll be good to go.



  • Thanks for that hint.

    If anybody needs alternative I put this

    lessThan(QT_MAJOR_VERSION, 5): DEFINES +="_qt4_=1"
    

    inside .pro file and some more

    #ifdef _qt4_
    

    inside .h and .cpp files and my console app compiles with qt4 and qt5

    Best Regards
    Marek


  • Lifetime Qt Champion

    Why re-invent the wheel ? There is already everything you need provided by Qt for such version check.



  • @SGaist could you please elaborate about the cast? I tried (int) and still get an error of "invalid conversion from ‘int’ to ‘QItemSelectionModel::SelectionFlag’ [-fpermissive]"

    If I add -fpermissive to the Makefile's CXXFLAGS, I get an error that the conversion is ambiguous.

    Thank you.



  • Is this the cast you mean? (QItemSelectionModel::SelectionFlag)


  • Lifetime Qt Champion

    No, it's static_cast.



  • in itemviews.cpp, I edited from:

    view()->selectionModel()->select(index, QItemSelectionModel::Columns & QItemSelectionModel::Deselect);
    

    to:

    view()->selectionModel()->select(index, static_cast<QItemSelectionModel::SelectionFlags>(QItemSelectionModel::Columns & QItemSelectionModel::Deselect));
    

    and at least it compile. Using gcc version 7.2.0 (Ubuntu 7.2.0-8ubuntu3)
