Build a QT/11 application for beagleboard black by cross compiling from ubuntu

Hi everyone,

I’m a little confused about how proceed to create QT/X11 applications for beaglebone black.
First of all i have succesfully developed, deployed and executed a first simple GUI QT/embedded application
following this tutorials http://www.cloud-rocket.com/2013/07/building-qt-for-beaglebone/
and now i’d like to build a similar application for X11.

Particularly, i don’t understand how to perform configure to build right libraries to copy to BBB.
Please help me, unfortunately i spent days in useless attemps to build QT/X11 for BBB that didn’t work.

Thanks a lot.

I don’t understand when you talk about “deployed” did you mean “on the BBB” ?
FYI I’ve also tried from the same blog you linked and have been tried it during days
with Angstrom and never succeeded .
Even if I’ve read many post about it here Qt on the BBB seems to be a hard path.
Or maybe we both missed a tutorial that should be officially posted somewhere…

Yes i meant on the BBB copying the executable file.
That tutorial worked well for me, consider that to run tha executable
you need to exit form X-environemt and launch the program with -qws
parameter.

Whati kind of problems did you have ?

I used the instructions and got a working BBB with a CAP LCD7. However I needed to cut the eMMC lines to the LCD CAP (BeagleToys one), it is a A3 Ref but still did not work, but the site say is 100% BBB compatible… ha ha . The only thing that does not work is the mouse when used with the LCD CAP, but that is not a problem to me as I used the touch screen. I made a document up with the instructions as I had to change some things to get the GUI , GDD and LCD cap working.

I also think QT creator has a bug , one has to delete the xx.user file and then setup the kit, else you cannot change the kit, it still uses the original kit. So just be sure to select the correct kit when started after the .user file was was deleted.

It works great !!

Building and setting up QT environment for BeagleBone

There are too few information available on how to easily setup QT environment for building Beaglebone applications (command line or GUI). In this tutorial we will compile QT and setup the environment from scratch.

1. My environment-

  • Target: BeagleBone Black running Angstrom

  • QT: 4.8.5

2. Setup Angstrom cross-compile toolchain for Linux

Download :

Run

$> tar -C / -xjf angstrom-2011.03-i686-linux-armv7a-linux-gnueabi-toolchain-qte-4.6.3.tar.bz2

3. Download and un-tar QT

wget http://download.qt-project.org/official_releases/qt/4.8/4.8.5/qt-everywhere-opensource-src-4.8.5.tar.gz

tar -xzf qt-everywhere-opensource-src-4.8.5.tar.gz

mv qt-everywhere-opensource-src-4.8.5 qt-4.8.5-beagle

4. Create qmake.conf

cd qt-4.8.5-beagle

mkdir ./mkspecs/qws/linux-am335x-g++

cp ./mkspecs/qws/linux-arm-g++/qplatformdefs.h ./mkspecs/qws/linux-am335x-g++

touch ./mkspecs/qws/linux-am335x-g++/qmake.conf

Add the following to qmake.conf with your favorite editor:

Hello List;

I got as far as Step 5 when I got this error.

I am using exactly the same host config as the author:

Ciao Mirko,

I’ve writen an answer but it seems to be in another thread or lost.
What I’ve said was that I tried and got (from mu comment on the blog ):

(…) even if I’ve follow all the steps the file on the target seems to miss libs : “-bash: ./TestQtapp: No such file or directory”
ldd gives “not a dynamic executable” while prints :
“ELF 32-bit LSB executable, ARM, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.16, not stripped”
Even I’ve installed Qt 5.1 I’ve checked that the app was created with the compiled 4.8.5 as said here.

So now my purpose is to be able to cross compile but now without Angstrom (using Debian currently).
I’ve seen in a comment that someone successfully compiled with Linaro Toolchain instead.
Please advise.

David

I performed only an additional step before to start that tutorial : i’ve installed GNU c++
compiler and everything worked.

8

i’ve neved had this kind of problem, just to clarify when do you get this ?
after you’ve copied executable on the BBB? or when you launch it with QT creator ?

9

I experienced a simpler way to work with qt embedded for BBB following Derek Tutorial
http://www.youtube.com/watch?v=kP7uvOu9hoQ where you don’t need to cross compile
QT:

  • install toolchain on your host
  • install qt4-embedded on BBB (opkg install qt4-embedded - fors-depends
  • create on your host a QT creator version from (/usr/local/angstrom/… qmake2)
  • create your kit to deploy app in BBB

The only problem i had is that installing qt4-embedded i had no linuxinput driver support for keyboard (because it’not in the default QT i guess)
so i had to cross-compile qt as shown in Meir tutorial(http://www.cloud-rocket.com/2013/07/building-qt-for-beaglebone/) with configure:

./configure -v -opensource -confirm-license -prefix /opt/qt -embedded arm -platform qws/linux-x86-g++ -xplatform qws/linux-am335x-g++ -depths 16,24,32 -no-mmx -no-3dnow -no-sse -no-sse2 -no-glib -no-cups -no-largefile -no-accessibility -no-openssl -no-gtkstyle -qt-mouse-pc -qt-mouse-linuxtp -qt-mouse-linuxinput -plugin-mouse-linuxtp -plugin-mouse-pc -fast -little-endian -host-big-endian -no-pch -no-sql-ibase -no-sql-mysql -no-sql-odbc -no-sql-psql -no-sql-sqlite -no-sql-sqlite2 -no-webkit -no-qt3support -nomake examples -nomake demos -nomake docs -nomake translations -qt-kbd-linuxinput

then to make mouse and keyboard work you have copy plugins dir in /opt/qt from your host to Beaglebone black and export like this before run your app:

QWS_MOUSE_PROTO = “LinuxInput:/dev/input/touchscreen0 MouseMan:/dev/input/mouse1” Touchscreen and mouse

QWS_KEYBOARD = “LinuxInput:/dev/input/event2 LinuxInput:/dev/input/event3:keymap=…/it.qmap” LDC keys and my usb keyboard mapped to italian layout

QT_PLUGIN_PATH = “/opt/qt/plugins” needed for keyboard and MouseMan drivers

It was very but at the end everything works fine !

Mirko :
Thanks for your answer.
Actually, I left Angstrom for a while ( independantly that it’s going to be replaced by Debian) so intend to use Debian instead. Nevertheless, I suppose that it’s not far from what you have done with Angstrom anyway.

11

As far as I know, the Angstrom toolchain comes with qmake for qt-embedded, the Linaro toolchain does not, hence the reason for cross compiling Qt.

When you cross compile Qt, you end up with an installation folder (like /opt/qt or /usr/local/qt). This folder is where you point Qt Creator (Tools → Options → Build & Run → Qt Versions). Qt Creator can then use the qmake executable, under the bin folder, to create your application to run on the BBB.

In fact, you shouldn’t need to compile the whole Qt project, just enough of the qmake tools to build apps to match the Qt version already installed on the BBB.

Running ‘ldd <app_name>’ on your host will result in “not a dynamic executable”, because it is an ARM binary. But if you transfer the binary file to the BBB and run ldd again it will show you the proper output.

I am working on this problem too.

I managed to “./configure” Ok.

Qt is now configured for building. Just run ‘make’.

Once everything is built, you must run ‘make install’.

Qt will be installed into /opt/qt

To reconfigure, run ‘make confclean’ and ‘configure’.

Hi William,

If you run the following command, what do you get:

/usr/local/angstrom/arm/arm-angstrom-linux-gnueabi/bin/g++ —version

From the above error, g++ is missing.

Regards,

John

Hi John:

When I cut and paste you command into the terminal I get:

beaglebone@ubuntu:~$ /usr/local/angstrom/arm/arm-angstrom-linux-gnueabi/bin/g++ —version

bash: /usr/local/angstrom/arm/arm-angstrom-linux-gnueabi/bin/g++: No such file or directory

If I simply enter:

beaglebone@ubuntu:~$ g++ -version

I get:

g++: error: unrecognized command line option ‘-version’

g++: fatal error: no input files

compilation terminated.

However, when I got to: /usr/local/angstrom/arm/arm-angstrom-linux-gnueabi/bin

Should there be two ³ - - ³ dashes ? Or did something go wrong with
./configure ?

Yeah, there are two dashes before version. The g++ in that folder is just a
symbolic link to another file which is two directories down in the bin
folder. Does this file exist relative to the original folder:
../../bin/arm-angstrom-linux-gnueabi-g++
Which I believe is this file:
/usr/local/angstrom/arm/bin/arm-angstrom-linux-gnueabi-g++
Does this file exist? My guess is it doesn¹t exist.

Clearly you do have a g++ on your system, but that would be the native x86
g++, and not the cross compile g++.

Try typing arm- and then hit the tab twice (autocomplete) to see if you have
any arm cross compiler installed on your system.

Regards,
John

Thanks John, I’ll try that.

In the mean time, the instructions I was following were: http://www.cloud-rocket.com/2013/07/building-qt-for-beaglebone/

If that helps any ?

Also I used “apt-get install g++” to install g++ on my desktop (development) system.

That was probably a mistake L

Actually if you talk about the qmake.conf : this is not a problem as it’s easy to change the paths to a different toolchain in there ( to point to -gcc -ld, etc) . I’d rather prefer to use the power of my PC to compile all and send binaries to the BBB . the ldd I have done was to show what were missing but at the end it was an arm format.

Hi John;

When I type arm-[tab][tab] it doesn’t autocomplete.

However, here is the contents of the directory you mentioned.

In the browser it shows as an executable, however when I try to “execute” it I get a “no such program” error message L

Could there be a conflict somewhere in the path or permissions ?

Did you install the right toolchain for your host, 32 bit or 64 bit. If 64 bit you need to include the ia32-libs (apt-get install).

I would also add /usr/local/angstrom/arm/ to your path:
export PATH=$PATH:/usr/local/angstrom/arm

Then try the arm-[tab][tab] again.
