    Default Qt creator application not display in Grayhill GHI270

    Im having "Grayhill GHI270" device having arm5vtel processor and trying to run qt creator project in it. For that i cross compiled qt creator (Qt version 5.5.0) using Angstrom cross compiler (http://web.archive.org/web/201308231...rg/toolchains/).

    After cross compilation if i execute the cross compiled Qt creator application , the application is executing fine but Qt creator display pop up not coming. I need your help to resolve this issue.

    I tried export QWS_DISPLAY = "LinuxFb :/ dev/fb0" also. The executable is running fine but only the display issue. Please guide me what are the dependencies / library files neede to display the application.

    QWS_DISPLAY sounds like it is for QWS, an early Qt4 embedded backend.

    Since you say (three times no less) that you are using Qt5, maybe it doesn't change anything because there is no QWS backend in Qt5?

    Also, if you intend to run QtCreator on the target, i.e. develop on that machine, why cross compile?
    You need a development setup on that machine anyway, no?

    Cheers,
