Re: [beagleboard] Running Qt gui application on BBB

2016-01-24 Thread Bremenpl

Hi there,
I was not able to solve this. Because of lack of time, I decided to install
qt 5+ on the bbb usong apt manager and build serialport (i needed ot and it
was not included) on the bbb itself. For now i am stuck with building on
bbb without crosscompiling as i wasnt able to set it for qt 5+ as well.

If you would find a solution to this i would be gratefull if you let me
know. I still need the qt on bbb in own frame buffer version.

 No one was saying change boards. Use the same board, but use a
 faster, more powerful ARM board to compile native ARM executable. The
 reasons are simple. No need to mess with cross compiling, which in many
 cases is messy, and sometimes near impossible.

 So just thinking for a minute. A Raspberry PI 2, the new board with quad 
 cores, and 1 GB ram would probably work fairly decent as a build system 
 for the Beaglebones. Granted, something like the X15, of that new nVidia 
 ARM board, or even the Omelex A20 board with SATA would probably be a much 
 better choice if cost is not a problem.
 
 By the way, I have no idea what Robert is talking about. You need to ask 
 him.

Hello there,
I managed to set up qt 5.3.2 on the beaglebone. I have build everything
there and it took ages but it works :).

For purely building armhf code, Odroid XU4 might be a good choice:

http://www.hardkernel.com/main/main.php

This is an Octacore processor with 4 CortexA15 and 4 CortexA7 processors. I
don’t know how good their kernel/debian support is, but I know Robert had
looked at this board or a predecessor in the past, so perhaps he can give
his input here.

Clearly this board doesn’t have the flexibility of the BeagleBoard-x15 with
it’s dual DSP, Dual CortexM4, Quad PRU, SATA interface, PCIe interface, etc.

Regards,
John

Anyway, the main problem with the rPI 2 is that it has no "fast" non

By the way, I have no idea what Robert is talking about. You need to ask him.

Now take into account that figuring out how to cross compile something like
this is a serious headache, and often takes days, if not weeks to get right
. . .
