4. Qt 5.1 MINGW

Qt 5.1 MINGW


  • Hi,

    I've installed Qt5.1 MinGW versione on both my PC (1 on Win7 with Intel Graphics Card, 1 on Win8 with NVidia Graphics Card).

    I built 1 example of QtControls on both machine and on Win7 it doesn't start. (I think is a problem related to OpenGL).

    Any kind of help?

    P.S. I've noticed in Qt-5.0.2 the D3D_Compiler.dll (it's the ANGLE dll); can I add ANGLE support in my Qt 5.1 installation without re-compile all?

    [/quote]No, unfortunately. Qt needs to be built with ANGLE support. The packages that you downloaded are for OpenGL only.

    I read on Qt docs I need OpenGL 2.1 support and my Graphics Card doesn't support it.

    At the moment I installed Qt 5.0.2; when I'll have time i recompile Qt 5.1

    Check Intel's website to see if there is an update available for your graphics card :) Their support for OpenGL has improved over the past year.
