Issue with New Signal/Slot mechanism In mingw (Qt5.2)



  • I have downloaded Qt5.2 mingw32 with opengl support. When i compile my project with this new version i get following error:
    @
    error: no matching function for call to
    mainwindow::connect(dialog*&, void (Dialog::*)(bool),dialog::on_btnExport_clicked()::__lambda0)
    });
    ^
    @
    Here is where i have defined my signal/slot connection:
    @
    connect(dialog, &Dialog::progressChanged,
    [=](bool started)
    {
    if (started)
    {
    // do something
    }
    else
    {
    // do something else!
    }
    });
    @
    This code was working fine with "Qt5.1 msvc 2010 opengl".
    How can i solve this issue?

    What is the signal signature?
    Have you enabled c++11 support in your project (CONFIG += c++11)? MSVC doesn't support language version selection but MinGW does and is set to C++03 by default.
