Not Able to run Qt Application in BeagleBone Black with Qt 5.7

[Milav]

@Andrey-Shmelew

you may be use wrong complier for the beagle bone black...

The host and Target specification are different from your specification.

I have 64 BIT bit Ubuntu on VMware and qt 5.7.0 is installed on that pc.
and i have Beagle Bone Black with debian 7.11 on it.

But i think cross-compiler toolchain is same for both of us...
so you can try with gcc-linaro-arm-linux-gnueabihf-4.8-2014.04_linux.tar.xz version.

and please check that you installed the sources at the time of installation.

Let me know if any progress occur..

Please open a new thread.

@Milav What system is running on your device? I never used BeagleBone Black, so I don't know what it uses.

Thanks for answer!
i have no idea how to install cross compiler gcc-linaro-arm-linux-gnueabihf-4.8 and how to use it.
I suppose it should be installed on my Ubuntu on virtual box?
it should be installed by "sudo apt-get install gcc-linaro-arm-linux-gnueabihf " or something like this?

to jslim: on BBB i have Debian 8 Image 2016-05-13

I am very appreciate for help because have a very tight time period for complete deploy my QT project on BBB.

@jsulm

on target device it installed Debian 7.11 Version.

[jsulm]

@Milav How is it configured? Do you have graphics there? Did you test any GUI applications?

[Milav]

@jsulm

yes , tried gui application on BBB. it running fine....

this Version is by default arrive when i purchase BBB.

@Andrey-Shmelew

you can download this version tool chain from linaro site.
just download that tool chain and extract it in known path.(like...in /opt/...) folder.

this is used when you set the complier path at time of qt creator configure..

[jsulm]

@Milav What does

ps ax | grep Xorg

print out on your device?

[Milav]

@jsulm said in Not Able to run Qt Application in BeagleBone Black with Qt 5.7:

ps ax | grep Xorg

the output is....
17946 pts/1 S+ 0:00 grep Xorg

[jsulm]

@Milav Looks like there is no X server. You should check the documentation to find out what is used: wayland, frame buffer, ...?

[Andrey Shmelew]

@Milav
sorry but i can not find gcc-linaro-arm-linux-gnueabihf-4.8-2014.04_linux.tar.xz, could you please give me a download link.

[Milav]

@Andrey-Shmelew

to solve below error :
QFontDatabase: Cannot find font directory /usr/local/qt5pi/lib/fonts.
Note that Qt no longer ships fonts. Deploy some (from http://dejavu-fonts.org for example) or switch to fontconfig.

just find fonts directory on your target and copy them without subdirectory in this /usr/local/qt5pi/lib/fonts for example i copied dejavu fonts file in this directory
