Mingw 64 bits + Qt 5.2



    1. I have seen this download : Qt 5.2.0 for Windows 64-bit (VS 2012, OpenGL, 589 MB) (Info)

    but I 'd like to use Qt 5.2 with mingw on my Windows 64 bits.

    Will it be online an installer with mingw64bits ?

    1. I have installed 32 bit version of mingw but I have an error with a platform "window" plugin.

    I copy/paste the file to the directory as I read but nothing works.

    Hi, and welcome to the Qt Dev Net!

    [quote author="fulgor2" date="1387090467"]Will it be online an installer with mingw64bits ?[/quote]No, the Qt Project will not be providing a 64-bit MinGW package. Each package takes lots of time to test, and there isn't enough resources to support so many packages (there are already 6 for Windows).

    You don't really need a 64-bit application unless you want to do lots of number crunching or memory-intensive tasks. Otherwise, 32-bit applications run just as well on 64-bit Windows.

    But if you really want 64-bit MinGW, one of the maintainers of the MinGW-w64 project has been providing unofficial 64-bit MinGW packages of Qt: http://sourceforge.net/projects/mingwbuilds/files/external-binary-packages/Qt-Builds/ Keep an eye on this site; he might provide one for Qt 5.2.0 soon.

    See http://qt-project.org/doc/qt-5/windows-deployment.html#shared-libraries for more deployment info.
