我尝试遵循 http://doc.qt .nokia.com/qt3d-snapshot/qt3d-building.html#installing-plugins

在完成所有编译过程后，它停留在：

我该如何编译它？ 有办法找到 ubuntu 的二进制和 -dev 版本吗？

也许是针对 64 位架构？

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

maybe is for 64 bit architecture?

我建议使用稳定的公共分支而不是旧的实验室分支。该实验室分支已经有一段时间没有维护了。在你做任何其他事情之前，先去获取最新的稳定来源。

话虽如此，上面的问题看起来像是 Qt 4 的问题。通常我会建议使用最新的 Qt SDK - 它内置了 Qt 4.7。但它的下载量很大。

如果您使用的是 Linux，特别是像 Ubuntu Lucid 这样的最新版本，可以获取 Qt 4.7 - 那么请尝试：

apt-get build-dep qt4-qmake

例如，在 Ubuntu Lucid 上应该获取所有依赖项，包括 Qt 4.7 开发库，这将节省您构建 Qt 的时间。然后只需执行qmake fast3d.pro即可使用已安装的系统qt。

如果您确实想构建 Qt（也许您需要能够将 qDebug() 语句放入 Qt 库中），那么您可以使用 Qt 下载页面中的源代码，或者从 gitorious 获取它们。然后按照构建线进行操作（如构建文档中所述）：

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

Qt3D 会定期在 64 位上进行测试，因此这应该不是问题。

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.

我也有同样的问题。您需要有 4.8 版本的 Qt。 Ubuntu 存储库中 Qt 的当前版本是 4.7.4。我通过添加 KDE 向后移植（PPA）解决了这个问题，其中包括 libqt4-dev:4.8.1 你应该这样做：

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

我目前正在 oneiric 上编译它；）

请注意，精确的穿山甲，将会上升后天。她的存储库中有 Qt 4.8.1。

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.
