Build qt3D with qt4 under Ubuntu 12.10

Hi, all:

I strictly follow http://doc-snapshot.qt-project.org/q...-building.html, but failed to build qt3D successfully.
Weird compilation errors keep bugging me all the time.

at the very beginning, I got

I don't even know what I've done to qt3d, now, it seems the program proceeds to

So, did anybody smoothly build qt3d with qt4 under ubuntu 12.10 ever?
And now, how to solve my problem "fatal error: qarray.h: No such file or directory"?
I can tell this qarray.h has already been installed to /usr/include/qt4/Qt3D

Did you read the bolded note in the manual? Are you building Qt3D against a Qt installation you have write permissions for?

Hi, thank you wysota:

I manually created needed directories. Also, I used
sudo qmake
sudo make


Now, I found a way out , but IMHO, to build current Qt3D is still annoying and problematic.
