    Hello to all!

    Host machine: VirtualBox Ubuntu 14.04 32 bit with Qt 5.5.1 installed on it
    Device: BeagleBone Black with debian 8.4 on it.

    I try to deploy any of example project on my BeagleBone Black board.

    So when i compile my Application for Desktop QT 5.5.1, on ubuntu, it goes good,
    but when i tried to upload my application on the Board, following https://www.youtube.com/watch?v=kP7uvOu9hoQ&t=525s, QT says:
    stdin: is not a tty
    bash: /home/root/coding: cannot execute binary file: Exec format error
    Application ended with error code 126 (Приложение завершилось с кодом 126).
    i used for this gcc (x86 32bit) compiler. i know that it's wrong compiler.

    alternate text

    When i choose right (in my mind) compiler arm-linux-gnueabi-gcc, an error "ompiler cannot produce code"

    alternate text

    Please see screenshots (sorry for cyrillic)
    i googled tons of pages, and still cannot deploy nothing on the board,
    spend weeks trying to crosscompile my app for beaglebone black , please help me

          Hi,

          Something's not clear from your description, did you cross-compile Qt for your BBB ?

          From what you wrote it looks like you first tried to run the x86 version of your application on your BBB and then you tried to compile your application with an ARM toolchain but still using your desktop version of Qt.

            Hi,

            Yes, i tried to crosscompile QT for my BBB,

            First I tried to run the x86 version of my application on my BBB and then i tried to compile application with an ARM toolchain but still using my desktop version of Qt, and it naturally did not work. So i tried to configure my QT opensource 5.5.1 on host ubuntu for BBB, and when i selected arm-linux-gnueabi-gcc, an error appeared: "Compiler "Compiler BBB" (arm-linux-generic-elf-32bit) cannot produce code for profile QT "QT 5.5.1 GCC 32bit" (x86-linux-generic-elf-32bit)". By the way, BBB Device responded normally, i can see list of processes.

            P.S. There is qt creator 4 installed on BBB, but i want develop project only on PC

                  @jsulm

                  after qt 5 install :
                  1 - added new kit
                  2 - added device type (generic Linux Device)
                  3 - added a device (linux device), ip address 192.168.7.2, port 22
                  4 - added GCC compiler, armv8l-linux-gnueabi-g

                  this step i can not do because can't find qmake file:
                  5 - added QT version with qmake file for arm

                    @Andrey-Shmelew said in Deploy on BBB: cannot execute binary file: Exec format error:

                    added QT version with qmake file for arm

                    Well, you need Qt built for ARM. That means you need to download Qt source code, call configure with correct parameters and then make;make install. qmake will be built during compilation. When you have Qt build for ARM then you can build your app for ARM.

                      but i have never compiled QT From source code, so will you provide me a good tutorial?
                      by the way, on this video https://youtu.be/eLr35wUrz6Q?t=248 the author just points qmake file

                        @Andrey-Shmelew Apparently the author already has an ARM build.
                        Cross compilation is not an easy task. I don't have any tutorial.
                        But you can search on internet, here is one for RaspberryPi: https://wiki.qt.io/RaspberryPi_Beginners_Guide

                            i have built qt for BBB as described in the link i posted in previous post and it finally works! I can deploy my QT project now. WOW!!! But not all projects. (sad)
                            Because of some reason apps that are built with qtquick does not start!
                            But there are a lot of videos with QtQuick running on BBB (for ex. https://www.youtube.com/watch?v=eDrBCzNSWaQ)
                            i think it happens because of absent of necessary drivers.
                            how can i start qtquick app on BBB,
                            could anybody help me with this problem?

                                Right! And as far as i know BBB does not have GPU.
                                But if you look at the video u can see working qtquick. (who knows maybe it is a cheating).
                                is it possible to make QtQuick without openGL using?
                                Thanks!

                                    there is a Qt Quick 2D Renderer, that works instead OpnGL ES 2 on boards without GPU like BBB, seems to be good for me.
                                    As described, i should use :
                                    export QMLSCENE_DEVICE=softwarecontext
                                    but i have no idea what does this string mean.
                                    Any thoughts?

                                      @Andrey-Shmelew It defines environment variable QMLSCENE_DEVICE and assigns it "softwarecontext" as value. I guess QtQuick checks that variable and activates software rendering if it is set to "softwarecontext".
                                      So, you first set this variable and then (in the same console) you start your application.
