I missed this answer, sry ; yes : this happend after built Qt app on host and tried to run it on BBB.
I guess I wasn’t clear, you need to type ‘arm-angstrom-linux-gnueabi-g++ --version’. Just typing g++ will use your regular host compiler (not toolchain cross compiler)
If that gives a valid response, you then need to modify your qmake.conf files or configure command line options (depending on Qt version and how you configured it) to point to the full binary name, not just g++.
From the error message, I doubt the error is in qabstractanimation.cpp, but you can look around for a local qmake.conf file, for that module, that may be pointing to the wrong g++.

Thanks for all the help Louis. I really appreciate it!
As you have probably guessed I am new to cross-compiling J

You’re welcome. Sometimes things sound so clear when I write them, but the next day…not so much 
I’ve created a howto on my blog, for building Qt 5.2 targeted at a BBB running Ubuntu. It is similar to the cloud-rocket site, but using the Linaro toolchain, and I start from the very beginning: Ubuntu virtual machine creation. I tried to be verbose, so maybe you can use it to double check your host configuration. Search for “Bare Metal Qt5.2 Beaglebone” if you are interested.
Qt 5.2 is very different from 4.x (QPA vs QWS), so I am not recommending that you change, especially if you have a working 4.x application. I am still trying to work out the GUI bugs and figure out exactly what modules I need to compile into Qt (the configure options have significantly changed from 4.x to 5.2)

Been there myself J

I’ll give it a look.

I think I’ll let YOU squash the bugs J In the mean time, I think I will start over from scratch with the cloud-rocket version.
This time I am going to make sure the compiler works before I continue with the rest of the steps!

Ok;
We have something weird going on here (?)
I started with a fresh VM and just installed the tool chain, from the file I had previously downloaded.
I then gave myself root access and went to the “/usr/local/angstrom/bin” directory.
Here’s what happened:
root@ubuntu:/usr/local/angstrom/arm/bin# arm-angstrom-linux-gnueabi-g++
arm-angstrom-linux-gnueabi-g++: command not found
root@ubuntu:/usr/local/angstrom/arm/bin# arm-angstrom-linux-gnueabi-g++ --version
arm-angstrom-linux-gnueabi-g++: command not found
root@ubuntu:/usr/local/angstrom/arm/bin# ./arm-angstrom-linux-gnueabi-g++ --version
bash: ./arm-angstrom-linux-gnueabi-g++: No such file or directory
When I type “ls –l” I get:

Looks to me like the program is executable. Could it be damaged or am I doing something wrong ?
Bill
Louis,
Could you please remind me the pointer to this how to?
I’m sure this could be ok for me on Debian.
David
@Bill
Can you run ‘uname -a’ from a terminal and post the results here?
What is the file name (or download link) of the angstrom toolchain that you downloaded?
@David
Sure. I have tried it with the Debian beta and it seems to be working.

Louis
Or just install ArchLinux and do pacman -S qt and be done with having to deal with compiling qt5 yourself. You can even install qt3 qt4 and qt5 all on the same box with this simple command pacman -S qt qt4 qt3
@Don & Louis
I feel really dumb L
I discovered my problem when I compared the post on this list to the Cloud-Rocket site.
The post on this list said the desktop environment was: Ubuntu 13.10 64bit (VB).
While the ones on the Cloud-Rocket site said: Ubuntu 12.10 32bit (VMplayer)
The reason I was having so much trouble is I was trying to run a 32 bit app in a 64 bit OS L
I built Ubuntu 12.10 32bit, and now things are rolling right along.
I have yet to compile the hello world program, but I’m getting there ……

Thanks Louis.
When you say “Debian Beta” I assume that it the official one, not the BBB (from Robert C Nelson) right ?
Well I have to try it myself btw.
For the record, Robert Nelsons Debian image is custom kernel only, with a “stock” file image. Also, as far as I know “Roberts Debian” is the only “official” Debian for the Beagelbone black.
Well i was refering to official Debian image as another possibility
How can i install the Robert’s Debian on my BBB?
I tested it on Robert Nelson’s Debian beta found at a link from this forum post:
https://groups.google.com/forum/m/#!category-topic/beagleboard/9EG0SbhwTx0
fine. This worth another test then, thanks Louis
Hi Louis,
I’m totally lost with cross compile with QT … I’ve the ubuntu distribution image from Robert Nelson.
Beagle :

And I’m trying to compile an hello world in my ubuntu VM VirtualBox ( 32bit ) .
l
I’ve downloaded angstrom-2011.03-i686-linux-armv7a-linux-gnueabi-toolchain-qte-4.6.3.tar.bz2
then tar -C / -xjf angstrom-2011.03-i686-linux-armv7a-linux-gnueabi-toolchain-qte-4.6.3.tar.bz2
and . /usr/local/angstrom/arm/environment-setup

the gcc that i’m using is here :

the QT version :

After, I put the file beagleTest in my beagle directory .
Beagle:
sudo chmod +x beagleTest
ubuntu@arm:~$ ./beagleTest -qws
-bash: ./beagleTest: No such file or directory
Why ?
ubuntu@arm:~$ readelf -h beagleTest

Your using ubuntu “armhf” yet building the appplication with a “gnueabi” based compiler…
“armhf” uses this linker:
/lib/ld-linux-armhf.so.3
“armel/gnueabi” uses this linker:
/lib/ld-linux.so.3
Use the correct “gnueabihf” toolchain…
