    Hi,

    Did you do anything as root before trying to build your application with Qt Creator ?



  • No sir,

    I have just developed SDK in yocto and tried to configured.

    while configuring i was getting " Failed to set up kit for Qbs: Could not determine whether Qt is a static build. " this error but configuration was done ,

    If i try to compile sample app, am getting above mentioned error in qt creator.

    HOST machine is 64 bit ubuntu 14.04:
    Target : ARM Cortex a8 - TI chip
    Qt Version is : 4.8.7
    Qt Creator is : 4.0

    i used below steps to develop sdk:

    $ source source_poky_jethro/oe-init-build-env build_jethro/
    $ bitbake -k core-image-sato
    $ bitbake -k meta-toolchain-qt

    In same SDK if i try to build my qt project in console, i can compile my sample project. i can get binary.
    In Qt Creator only am getting error.

    Help me ,

    Thank you

    Looks like there's something funky with your kit. It's in fact trying to execute the file.



  • i have compiled qt 4.8.7 manually , now its working .

    Thank you
