我该怎么编译呢？ 有办法找到ubuntu的二进制和-dev版本吗？
也许是64位架构？
答案 0 :(得分：0)
我建议使用stable public branch而不是旧实验室分支。该实验室分支尚未维持一段时间。在你做任何其他事情之前，去获取最新的稳定来源。
上面说过上面的问题看起来像是Qt 4的一些问题。通常我会建议使用最新的Qt SDK - 内置Qt 4.7。但它下载量很大。
如果您使用的是Linux，特别是如果它的最新版本如Ubuntu Lucid可以获得Qt 4.7 - 那么请尝试：
apt-get build-dep qt4-qmake
例如，Ubuntu Lucid应该获得所有依赖项，包括Qt 4.7开发库，这将为您节省构建Qt。然后只需qmake quick3d.pro使用已安装的系统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下载页面中的源代码，或者从功能上获取它们。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位上定期测试，因此不应该是一个问题。

我遇到了同样的问题。您需要拥有Qt的4.8版本。 Ubuntu存储库中当前版本的Qt是4.7.4。我通过添加KDE backports（PPA）解决了这个问题，其中包括libqt4-dev:4.8.1你应该做的事情：
sudo add-apt-repository ppa:kubuntu-ppa/backports
sudo apt-get update
sudo apt-get install libqt4-dev
我目前在oneiric上编译它;）
请注意，准确的穿山甲，后天会上升。她的知识库中有Qt 4.8.1。
