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.

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.

I tried the first hint:

Theb second:

QXcbConnection: Could not connect to display :0

Is there something more I should specify?

Try it this thus way:

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.

Okay, thank :P. I am quite sure raspberry pi is not hard float.

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.

I have just flashed my BeagleBone Black emmc with lxqt image
linked by Robert. I cant seem to find qmake anywhere. I thought there would
be qt installed and all. Am I missing something again?

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 board that is
more powerfull than beagle just to compile 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 . . .

Okay guys, atm I am donwloading the lxqt image. AT first I will
try to open the app on the BeagleBone Black itself. But after that works I
need to figure out how to remote debug while building on beagle instead of
cross compile on host.
Could you please onl
