compiling qt3d on ubuntu

i have tried to follow the http://doc.qt.nokia.com/qt3d-snapshot/qt3d-building.html#installing-plugins

after all the compiling process it stuck on:

how can i compile it? there is way to find binary and -dev version for ubuntu?

maybe is for 64 bit architecture?

---

I suggest using the stable public branch rather than the old labs branch. That labs branch has not been maintained for a while. Before you do anything else, go get the latest stable sources.

Having said that the problems above look like some issue with Qt 4. Normally I would recommend using the latest Qt SDK - which ships with a Qt 4.7 built in. But its a big download.

If you are on linux, especially if its a recent version like Ubuntu Lucid which can get Qt 4.7 - then try:

apt-get build-dep qt4-qmake

On for example Ubuntu Lucid should get all the dependencies including the Qt 4.7 development libraries, which will save you building Qt. Then just do qmake quick3d.pro to use the installed system qt.

If you really want to build Qt (maybe you have a need to be able to put qDebug() statements in the Qt libs) then you can use the sources from the Qt downloads page, or get them from gitorious. Then follow the build line (as described on the build doc):

 /path/to/qt/configure -developer-build -no-qt3support -no-webkit -no-xmlpatterns \
  -no-phonon -opengl -declarative -nomake demos -nomake examples

Qt3D gets regularly tested on 64 bit so that should not be a problem.

I had the same problem. You need to have the 4.8 version of Qt. Current version of Qt in Ubuntu repositories is 4.7.4. I solved the issue by adding KDE backports (PPA) which includes libqt4-dev:4.8.1 you should do:

sudo add-apt-repository ppa:kubuntu-ppa/backports 
sudo apt-get update
sudo apt-get install libqt4-dev

I'm currently compiling it on oneiric ;)

Please note that the precise pangolin, will rise the day after tomorrow. She has Qt 4.8.1 in her repositories.
