    I want to use qt quick in our own device which run embedded linux on a powerpc cpu, but the device doesn't support openGL. So, I cross-compiled qt with opengl support and qt quick 2d render. Everything seems ok. Then, I cross-compiled a HelloWorld qt quick project, and deploy it to our device, run it, no error messages, but the LCD doesn't say "Hello World" as I expected.
    Ps: Our embedded device can support linuxfb, and widget poject is ok.

    Can anyone give me some suggestion? Thank you.

      Hi and welcome to devnet,

      Maybe a silly question but did you call export QMLSCENE_DEVICE=softwarecontext before starting your application ?

      If this is not enough, Qt Quick 2D renderer is a licensed feature, you should contact the Qt Company in the help center on your Qt Account page
