Solved Deploy on BBB: cannot execute binary file: Exec format error
i suppose i need to change qt profile from x86 to arm, but i can not find qmake file for arm
@Andrey-Shmelew How did you call configure?
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
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.

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?
@Andrey-Shmelew As far as I know QtQuick requires OpenGL?
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?
@Andrey-Shmelew Probably software rendering. But I don't know how to activate it. Maybe anybody else knows?
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 :
but i have no idea what does this string mean.
@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.
mark as solved, please
@Andrey-Shmelew Sorry, it's your thread you should mark it as solved.
An another issue,
i want to use Charts in my application.
When i compile app for Windows,its okay, but when i compile it for Linux, it can not find charts module (Unknown module(s) in QT: charts), even if there is 'QT += charts' inside myproject.pro file. As i understand, i need to rebuild qt creator for linux with charts module, right?
