[solved] Poor rendering on Windows machine



  • Hi I'm using Qt5.2.0
    I wrote and run good on Ubuntu machine. But when I recompile and run it on Windows7 machine , which has Qt5.2.0 mingw, the result is very poor, not as good as it on Ubuntu. And the following messages output.


    getProcAddress: Unable to resolve ‘glBindFramebuffer’
    getProcAddress: Unable to resolve ‘glBindFramebufferOES’
    getProcAddress: Unable to resolve ‘glBindFramebufferARB’
    getProcAddress: Unable to resolve ‘glGenFramebuffers’
    getProcAddress: Unable to resolve ‘glGenFramebuffersOES’
    getProcAddress: Unable to resolve ‘glGenFramebuffersARB’
    getProcAddress: Unable to resolve ‘glFramebufferTexture2D’
    getProcAddress: Unable to resolve ‘glFramebufferTexture2DOES’

    getProcAddress: Unable to resolve ‘glFramebufferRenderbuffer’
    getProcAddress: Unable to resolve ‘glFramebufferRenderbufferOES’
    getProcAddress: Unable to resolve ‘glFramebufferRenderbufferARB’

    The video card on the Windows machiner is Mobile Intel® 4 Series Express Chipset Family.

    Hi and welcome to devnet,

    There are two solutions proposed:

    change your Qt package by installing the ANGLE version.

    ensure that you have the latest OpenGL driver installed

    Hope it helps



  • Hi, many thanks for your advice.
    Could you please share the info where I can get the installer of ANGLE version for windows machine? I will try it.
    Thanks and kind regards.

    You can find them on the download page, it's those without OpenGL in their name



  • Yes, It works!
    Many thanks!
