    Hello,

    I'm trying to migrate my project from Qt4 to Qt5. QtConcurrent is no longer shipped in Qt5. Where can I download it, it is compatible ?

    Thanks

      What makes you think it isn't included?

      It's in the Qt 5.0 documentation:
      http://qt-project.org/doc/qt-5.0/qtconcurrent/qtconcurrent.html

      And in the source tree:
      http://qt.gitorious.org/qt/qtbase/trees/stable/src/concurrent

      (Note: It is in the "qtbase" sub-module of Qt 5, because Qt has been modularized)

      My OpenSource software at: http://muldersoft.com/

      Qt v4.8.6 MSVC 2013, static/shared: http://goo.gl/BXqhrS

        You're right. I was not looking in the right folder.
        Thanks

          in Qt5, try the follow way:

          #include <QtConcurrent/QtConcurrentMap>
          #include <QtConcurrent/QtConcurrentRun>

          but if we edit our pro file like this:

          LIBS += -lQt5Concurrent

          may be the best way.

            Hi. I have the same problem too. Keep saying undefined reference to bla bla bla...

            After adding
            @
            LIBS += -lQt5Concurrent
            @

            to my project file and
            @
            #include <QtConcurrent/QtConcurrent>
            @

            to my source file the code build and run as expected. Thanks!

              Also you should add to project file
              @QT += concurrent@

              "See here":http://qt-project.org/doc/qt-5.0/qtconcurrent/map-map-pro.html
