  Problem cross compiling (QT5) Qt3D to raspberry Pi

  QGLview is now a subclass of Qwindow not Qwidget.

  Just change the constructor argument to:
  @TeapotView(QWindow *parent = 0)@

  And you should be good to go.

  The documentation for QT3D is atrocious now'a'days.

  But you can checkout updated examples directly from the git repos.

  Updated the swap file to 8GB, and it's seems OK for now, but the build is very very slow.

  I managed to fix this by choosing a correct sysroot. The one it was pointing at had a broken symlink, which caused the library to fail

  I managed to install qt50-snapshot when I used "deb http://archive.qmh-project.org/rpi-wheezy/debian unstable main" line in /etc/apt/sources.list. I didn't get my cross-compile environment to work though. My Qt creator doesn't found target device after I installed qt50-snapshot.

  Thank you for the hint. I have unmounted the raspbian image before I tried to configure the Qt Verions. Remounting the image solves the problem and now it works as expected.

  Hello, I don't know whether this thread is active or not so simply try. I have used the bakeqtpi.bash script from http://qt-project.org/wiki/RaspberryPi_Beginners_guide. At the end I got the following messages:

  Compiled qtimageformats
  Compiled qtsvg
  Compiled qtjsbackend
  Compiled qtscript
  Compiled qtxmlpatterns
  Compiled qtdeclarative
  Failed qtsensors
  Failed qt3d
  Compiled qtgraphicaleffects
  Failed qtjsondb
  Failed qtlocation
  Compiled qtquick1
  Failed qtsystems
  Compiled qtmultimedia

  What exactly does this mean to me? Will QT5 run properly on my PI?

  thanks for your feedback

  Thanks for your help. I was able to solve this "myself" though, but had not yet posted the answer here.

  The problem was not with the libraries for the target, but for the host. I had it installed on a 64-bit machine, and the libraries had to be 32 bit. It compiled fine after I installed the i686 versions of libz-devel and libmpc-devel.

  There was something funny with the libz though. The compiler gave me errors, saying that it could not get the version information for zlib, unable to find the absolute file location. I was able to ls -l it though. It showed a symlink pointing from libz.so.1 to libz.so.1.x.x (I don't remember the exact version). I deleted and recreated this symlink, and it was fixed.

  Now I just have to get qt working on the pi...

  @jcverdie

  I followed the beginners guide like yourself also and ran into the same problem.

  Apps deployed and executed from within QtCreator ran correctly on the device but if I went to the command line on the RPi itself, I couldn't execute them (libQtQuick.. not found)

  Running: export LD_LIBRARY_PATH=/usr/local/qt5pi/lib/

  Fixes this problem but only when logged in as root!

  If I export LD_LIBRARY_PATH as user 'pi' I still cannot execute the binary (same error as before).

  Stranger still, QtCreator which can deploy and run the binary correctly, is logging in via ssh with user 'pi' !

  Any ideas why this is happening?

  Update your distribution. Glibc is the basis for almost every application in your distribution, so the only reliable way to update it is to update the distribution where everything is then tested with the new glibc.

  If you do not want to update your linux: Rebuild Qt Creator, Qt, etc. using your old distribution. That way you get binaries that are compatible with your system.

  You did not ask for an opinion, you asked for resources. They can be found using Google, as was rightly pointed out to you.

  With exporting QT_DEBUG_PLUGIN=1, you can see if the plugin is found.
  if the "Key" word matches with what every you have passed for -plugin, then it should be initialized. If further to that if its not working, then probably you are not getting mouse events.

  As I wrote, I used the linuxfb plugin for QPA. But I have to mention this was on 4.8, which claimed to support QPA, but I didn't have the feeling this is really true in terms of usability. So, if there is no working linuxfb in Qt5 now, I sadly have no chance to try Qt5 on our platform.

  I guess at some point I will have to fix linuxfb by myself. ;-)

  Done. You're so impatient! ;)[/quote]

  Alexandra, could you please check the requests for adding a wiki and a forum to the QtonPi group?

  Sorry for being impatient again but a lot of people have already joined the group and there are topics to discuss :)
