I am not sure about this but I think I read somewhere that QT 5.3.x does
not support the "qws" anymore. I run QT 5.3.1 with -platform linuxfb
only and it works. I did compile with eglfs but have not been able to
get that to work either.
Have you finally solved this problem? If so, could you please give some
advice how to fix this problem?
I am stuck in the same place right now. Trying to run an example after
cross compiling qt for BBB.

Theb second:

Is there something more I should specify?

i haven’t done this in ages, but try to run your QT app with the
"-platform eglfs” option. I’m assuming you built QT with EGL.

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 .
Next step is that I need to check either it is possible to run qt
app on bbb without gui with qws parameter. Because at the moment
when i run it with qws i get QXcbconnection: Could not connect to
display. I need to do it like this because thw gui is really
really slow.

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.

Anyway, the main problem with the rPI 2 is that it has no "fast"
non destructive storage. But the Omilex . . let me look it up.

Has SATA and GbE both. Dual cores too I think. However, you'd
have to ask someone who has one how well they think it would
work as a build board. RObert might know, as his Debian build
guide also includes this board too I believe.

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.

Not necessarily, but consider this. How much does an
embedded systems specialist in your area get paid per hour
? In my area, about 15-20 years ago. The cost of a board
like the X15 would have been absorbed in roughly half a
day. That is to say, an embedded systems specialist could
buy a board for $239 after working roughly half a day.
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 . . .

So if I understand correctly, I should have a second

the code for beagle?

I cant change the board right now, it has to be
BeagleBone Black. Thats why I need to build on my host.
Did you succed on installing QT5.1 and deploying it to
BeagleBone Black? Maybe I should use it instead of
4.8.6 if its easier?
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.
You don't think Robert spends days, or weeks compiling
packages do you ? But why don't we ask Robert. Robert,
hey what percentage of the packages you build are
compiled native to ARM, from some sort of beefy ARM
board? I'm guessing nearly 100% if not 100% but . . .

first I will try to open the app on the BeagleBone

out how to remote debug while building on beagle
instead of cross compile on host.
Could you please onl
