使用QtCreator和qt5安装Qt3D时出现错误

Question

我尝试在Windows 8上使用QtCreator 5.1.1安装Qt3D，但是我无法成功。

首先，我按照文档中给出的步骤进行操作：

• 在git://gitorious.org/qt/qt3d获取源代码
• 在QtCreator中打开.pro文件
• 将"install"和"-j 3"参数添加到make命令中

当我构建项目时，我收到以下错误信息：

    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.

    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"

因此，我在文件夹“C：\ Qt \ Qt5.1.1 \ 5.1.1 \ mingw48_32 \ include”中创建了以下文件夹：

• Qt3D：我将qt3d源代码的src / threed文件夹中的所有.h文件复制到此文件夹中
• Qt3DQuick：我将qt3d源代码的src / quick3d文件夹中的所有.h文件复制到此文件夹中

我重新运行编译，然后出现以下错误：

我尝试将所有需要的.h文件复制到它们所需的源文件夹中，但没有效果。此外，我认为必须有另一种方法来获得我想要的，但我看不到如何实现。

如果有人能帮助我，我会很高兴。

我有一种成功的方法：

• 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
  

"安装"非常重要，因为这样可以将所有文件复制到Qt配置文件夹中。

然后，在.pro文件中添加：

QT += 3d

在 main.qml 文件中：

import QtQuick 2.0
import Qt3D 2.0
import Qt3D.Shapes 2.0
