編譯qt3d在Ubuntu

我試圖按照http://doc.qt.nokia.com/qt3d-snapshot/qt3d-building.html#installing-plugins 編譯qt3d在Ubuntu

所有的編譯過程中它貼在後：

我怎樣才能編譯它？有辦法找到ubuntu的二進制和-dev版本？

也許是64位體系結構？

你是否按照Qt3D頁面的說明先編譯Qt？ – 2011-04-27 13:54:09

當然我也遵循同樣的目錄結構，使用./configure -opengl – 2011-04-27 14:27:15

編譯的qt你不需要編譯Qt本身。只要確保你安裝的Qt版本是4.8或以上 – 2012-04-24 17:25:28

我建議使用stable public branch而不是老的實驗室分支。該實驗室的分支尚未維持一段時間。在你做任何事之前，去獲取最新的穩定來源。

說了上面的問題看起來像是Qt 4的一些問題。通常我會推薦使用最新的Qt SDK - 內置Qt 4.7。但是它的下載量很大。

如果你是在Linux上，尤其是當它像Ubuntu清醒最近的版本，它可以得到的Qt 4.7 - 然後嘗試：

apt-get build-dep qt4-qmake

在例如Ubuntu的清醒應該讓所有的依賴，包括了Qt 4.7的發展圖書館，這將節省您建立Qt。然後，只需執行qmake quick3d.pro即可使用已安裝的系統qt。

如果你真的想建立QT（也許你有一個需要能夠把qDebug（）中的Qt庫報表），那麼你可以使用源從Qt的下載頁面，或從gitorious得到它們。然後按照構建線（如在構建文檔中描述）：

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

Qt3D得到在64位定期進行測試，以便不應該是一個問題。

我有同樣的問題。你需要有4.8版本的Qt。 Ubuntu版本庫中的Qt的當前版本是4.7.4。我解決了這個問題，通過增加KDE反向移植（PPA），其中包括libqt4-dev:4.8.1你應該做的：

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

我目前正在對其進行編譯precise中;）

請注意，精確的穿山甲，將上升的日子明天之後。她的倉庫裏有Qt 4.8.1。
