  • I work with cross-compiled application in ubuntu 16.04 for a freescale imx6, in the moment of run the application show me this error:

    There's something fishy, you have -d not found error, where does it come from ?
    The other error seems to be that the system tries to execute main window.ui rather than run uic on it.

  • @SGaist , The error can't be programming, because only use a button, but in my main.cpp in the #include <QAplication> show me the QApplication no such file or directory and tha tab General Message display following text Failed to set up kit for Qbs: Could not determine whether Qt is a static build..

    My cross-compile application is based in this link:

  • Lifetime Qt Champion

    What project manager are you using for your project ?

    If qmake, then you are likely missing QT += widgets in your .pro file hence your error about QApplication.

    Your link is only available to registered users.

  • Already add Qt += widgets and reboot Qtcreator in my .pro, but display the same error, the access is XXX and XXX.

    [edit: removed credentials SGaist]

  • Lifetime Qt Champion

    The name of the variable is QT.

    Did you re-run qmake before re-building ?

  • @SGaist , Is correct the variable, sorry, i have tried before create a qmake, but i had a problem with that and have the files, you think you should delete the files??

  • Lifetime Qt Champion

    @Alexander-9 What files do you mean? After changing pro file you need to run qmake again and then rebuild.
    Can you show the content of your pro file?

  • @jsulm I have been working with cross-compile application this way:

    ./configure -opengl es2 -prefix /usr/local/qt5 -extprefix opt/qt5 -device linux-imx6-g++ -device-option CROSS_COMPILE=/opt/poky/2.0/sysroots/x86_64-pokysdk-linux/usr/bin/arm-poky-linux-gnueabi/arm-poky-linux-gnueabi- -sysroot /opt/poky/2.0/sysroots/armv7a-vfp-neon-poky-linux-gnueabi -nomake examples -nomake tests -v

    But it shows me this error, do you know solve this, thanks: Screenshot

    Looks like your sysroot doesn't contain the needed OpenGL development stuff.

    On a side note: don't build/develop as root you can brick your system without knowing.

  • @SGaist , @jsulm This are steps to get the toolchain:

    • Inside of poky: source oe-init-build-env build.
    • Configure local.conf for the type of machine, in this case is imx6solosabreauto.
    • After of download the toolchain, run ./
    • Later the url when is the toolchain is the following: /opt/poky/2.0.3/sysroots/x86_64-pokysdk-linux/usr/bin/qmake2.

    I need do other steps more, hope you help me, thanks.
