在ubuntu上编译qt3d
compiling qt3d on ubuntu
我已经尝试遵循http://doc.qt.nokia.com/qt3d-snapshot/qt3d-building.html#installing-plugins
在所有编译过程之后，它卡住了:

如何编译它?有办法找到二进制和-dev版本的ubuntu?
可能是64位架构?
我建议使用稳定的公共分支而不是旧的实验室分支。那个实验室分支已经有一段时间没有维护了。在你做任何事情之前，去获取最新的稳定源代码。
上面的问题看起来像Qt 4的一些问题。通常我建议使用最新的Qt SDK——它内置了Qt 4.7。但是下载量很大。
如果你使用的是linux，特别是Ubuntu Lucid这样的最新版本，它可以支持Qt 4.7，那么试试:
apt-get build-dep qt4-qmake
举个例子，Ubuntu Lucid应该得到所有的依赖，包括Qt 4.7开发库，这将节省你构建Qt，然后只需要执行qmake quick3d.pro来使用安装的系统Qt。
如果你真的想构建Qt(也许你需要能够在Qt库中放置qDebug()语句)，那么你可以使用Qt下载页面的源代码，或者从giitorious获得它们。然后按照构建行(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在64位上进行定期测试，因此应该没有问题。
我也遇到了同样的问题。你需要使用4.8版本的Qt，目前Ubuntu软件库中的Qt版本是4.7.4。我通过添加KDE后台端口(PPA)解决了这个问题，其中包括您应该做的libqt4-dev:4.8.1:
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;)
请注意，精确的穿山甲，将在后天升起。她的软件库中有Qt 4.8.1。
