Error installing Qt3D with QtCreator and qt5

Question

I tried installing Qt3D using QtCreator 5.1.1 on Windows 8, and I can't figure out how to succeed.

First, I followed the steps given in the documentation:

• get the sources on git://gitorious.org/qt/qt3d
• open the .pro in QtCreator
• add the "install" and "-j 3" arguments to the make command

When I build the project, I get the following error:

    In file included from D:\qt3D\project\qt-qt3d\src\threed\global\qglnamespace.cpp:42:0:
    D:\qt3D\project\qt-qt3d\src\threed\global\qglnamespace.h:45:29: fatal error: Qt3D/qt3dglobal.h: No such file or directory
     #include <Qt3D/qt3dglobal.h>
                                 ^
    compilation terminated.
    Makefile.Debug:2547: recipe for target '.obj/debug_shared/qglnamespace.o' failed

    Erreur lors de la compilation/déploiement du projet qt3d (kit : Desktop Qt 5.1.1 MinGW 32bit)
    Lors de l'exécution de l'étape "Make"

So I created the following folders into the folder "C:\Qt\Qt5.1.1\5.1.1\mingw48_32\include":

• Qt3D: I copied there all .h files located into subfolders of the src/threed folder of the qt3d sources
• Qt3DQuick: I copied there all .h files located into the src/quick3d folder of the qt3d sources

I re-run the compilation, and then I got the following errors:

    D:\qt3D\project\qt-qt3d\src\quick3d\qquickeffect.cpp:44:24: fatal error: qglpainter.h: No such file or directory

So, I tried to copy all needed .h file into sources folders where they are needed, but I didn't work. Moreover, I think there must be another way to get what I want, but I can't see how.

I someone could help me, I would be glad.

Answer 1

I got a way to succeed:

• first I downloaded the latest version of Qt, Qt 5.2.1
• I downloaded the sources of Qt3D from "git://gitorious.org/qt/qt3d" with a git client into the folder “C:\qt3d”

• with the terminal “Qt 5.2.1 for Desktop (MinGW 4.8 32 bit)”

  cd C:\qt3D
  qmake
  mingw32-make.exe install
  

the “install” is important so that all files are copied into Qt configuration folder.

Then, in the .pro file, add

QT += 3d

And in main.qml file:

import QtQuick 2.0
import Qt3D 2.0
import Qt3D.Shapes 2.0
