Re: [beagleboard] Re: Finally : did someone succeeded to have a Qt GUI app ?

[David Lewin]

Thanks for your answer Hal.
I succeeded to build apps on my PC but the failing part is when
cross-compiling from PC and executing it to BBB.
Does this mean that a Qt application can only be developped from the board
, instead of QtCreator on PC as usual ?

Debian is using the "armhf" abi, so make sure your cross compiler is
of the "gnueabihf" variety..

Re: [beagleboard] Re: Finally : did someone succeeded to have a Qt GUI app ?

[David Lewin]

Indeed, as I've already got the case now I pay attention to that point: the
gnueabihf from Linaro were used as in the Louis good tutorial  :
http://armsdr.blogspot.fr/2014/01/bare-metal-qt-52-on-beaglebone-black_16.html
Anyway, whereas the cross-compilation was ok-the app execute fine- the
display can't show GUI correctly (no btn, no label, ...) it seems that
everybody has that issue. I've looked in the forums (official Qt about BBB
included) for an alternative of linufb (xcb as instance) without better
results.
Therefore, I wonder if Qt is able to be cross-compiled for BBB.

Re: [beagleboard] Re: Finally : did someone succeeded to have a Qt GUI app ?

[Hussam Hertani]

David, yes absolutely You can build applications natively on the BBB using
a native compiler (ygcc compiler on the BBB not a cross compiler...) and a
native set of the QT4 libraries. Expect slightly slower build times though.
Also running QtCreator natively on the BBB might be a bit laggybut
usable. I typically build the applications from the command line. This
approach uses a pre-built armhf version of QT4 from the debian repos. It is
not as flexible as a custom QT library build and requires Xorg/server but
it works.

Re: [beagleboard] Re: Finally : did someone succeeded to have a Qt GUI app ?

[Hussam Hertani]

David you can definitely cross-compile QT apps for the BBB as wellI
just found the process
 to be somewhat unwieldy. Getting native compilation to work is much easier
and achieves more or less the same thing most of the time

Hussam,
export DISPLAY in the profile didn't changed the behaviour.I've tried with
and without lxds started

What I wonder the most is that the Qt app shouldn't need the X when
starting with "-qws" option, or "-plaform linuxfb".

Re: [beagleboard] Re: Finally : did someone succeeded to have a Qt GUI app ?

[Hussam Hertani]

David I'm currently running a headless setup on my BBB...I have xorg and
libqt4-dev packages installed (qt-sdk package encompasses libqt4-dev,
qtcreator and some additional packages)

   - I SSHed into the BBB with X11 Forwarding: ssh -X debian@192.168.0.102
   - Made a directory containing a sample application
   - built it using "qmake -project", "qmake" & "make"
   - and ran the binary successfully!

This seems to work with SSH+X11 forwardingI will try it with the latest
Debian image +LXDE+Nodejs from http://beagleboard.org/latest-images here
and report back.

I'm attaching a compressed folder containing the example code and a pic of
the GUI UI as displayed over SSH+X11. I'm running Debian Jessie on my PC
and the latest Debian demo-image (headless)
http://elinux.org/BeagleBoardDebian on my BBB.

That a good example.
I've tried with the provided executable and build it myself also from the
board :
both gave the same results, even with ssh+X
BUT, what I see is that you use a different image as me: I ve used the git
repo and did a:

beagleboard.org_image.sh http://beagleboard.org/source


to use the setup_sdcard.sh as explained.

Maybe this is the problem root cause

Re: [beagleboard] Re: Finally : did someone succeeded to have a Qt GUI app ?

[Hussam Hertani]

David,
If you are running an image with a Debian root filesystem this should work
no problems. I don't think that the QT4 built  in the Debian apt-get  armhf
repos was built with the -qws and -linuxfb options. As such it should only
work with X11. But I could be wrong as I can't quite confirm it.

I use the demo image available here..http://elinux.org/BeagleBoardDebian. I
always used it...never really bothered with angstrom even with the older
Beaglebone white. This image is headless and somewhat barebones. I also
really like the new official Debian release
http://beagleboard.org/latest-images. It comes with LXDE which is a very
good desktop environment for the BBB. andNodeJs..yuck!

 Hi,

 Is there finally someone who succeeded to have a GUI compiled with Qt
 (from Debian for example ) ?

 I've tested many things, and they either rely on Angstrom (which I'd
 like to avoid) or don't work at all (Timesys included)

 So I'm looking for a successful try ...

[Cody Lacey]

If you are using debian
SSH to your BBB but instead of loging in as root log in as
username: debian (or whatever local username you use)
password: temppwd (or local password)

export DISPLAY=":0"
xhost +

Then try running your application

 Make sure that you use a 4GB+ microsd. After burning the image onto
 the microsd, make sure you expand the root filesystemyou will need
 the space.

[Micka]
