    Hi,
    i have compiled Qt 5.0.2 with Visual Studio 2012 for x86 and with opengl.
    But there is a problem with the platforms/qwindows.dll. Creating a Qt Application works well,
    but when I start it, it tells me "Failed to load platform plugin 'windows'. Available platforms are:" (there are no platforms listed)
    When I keep the compiled QT version at the place where it was built into (in the visual studio program path), it works, but I think thats not the way it is meant to be.
    When I use the pre-compiled Version from the qt download page everything works well. So is there missing some thing to configure?
    Thanks a lot

      Yesterday, I had the same problem with Visual Studio 2008. The solution was:

      Add the following lines to your application code:
      #include <QtPlugin>
      Q_IMPORT_PLUGIN(QWindowsIntegrationPlugin)

      Link these libs to your application:
      opengl32.lib
      imm32.lib
      winmm.lib
      Ws2_32.lib
      Qt5PlatformSupport.lib
      qwindows.lib

        @danielesd said in Platform "windows" not found...:

        Q_IMPORT_PLUGIN(QWindowsIntegrationPlugin)

        I was trying to follow these steps but, when I build workspace with Q_IMPORT_PLUGIN(QWindowsIntegrationPlugin) it says undefined reference to 'qt_static_plugin_QWindowsIntegrationPlugin()'
