компилирование qt3d в Ubuntu

Question

Я пытался следовать http://doc.qt.nokia.com/qt3d-snapshot/qt3d-building.html#installing-plugins

после всего процесса компиляции он застрял:

как мне его скомпилировать? Есть ли способ найти бинарную версию и версию -dev для Ubuntu?

может быть для 64 битной архитектуры?

Answer 1

У меня была такая же проблема. Вам нужна версия Qt 4.8. Текущая версия Qt в репозиториях Ubuntu - 4.7.4. Я решил проблему, добавив бэкпорт KDE (PPA), включающий libqt4-dev:4.8.1, который вы должны сделать:

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

Я сейчас собираю его на oneiric;)

Обратите внимание, что точный панголин, вырастет послезавтра. Она имеет Qt 4.8.1 в своих хранилищах.

Answer 2

Я предлагаю использовать стабильную публичную ветку вместо старой ветки labs.Эта ветвь лабораторий некоторое время не поддерживалась.Прежде чем делать что-то еще, перейдите к последним стабильным источникам.

Сказав, что описанные выше проблемы выглядят как некоторые проблемы с Qt 4. Обычно я бы порекомендовал использовать последний Qt SDK - который поставляется со встроенным Qt 4.7in. Но это большая загрузка.

Если вы работаете в Linux, особенно если это последняя версия, такая как Ubuntu Lucid, которая может получить Qt 4.7 - тогда попробуйте:

apt-get build-dep qt4-qmake

On, напримерUbuntu Lucid должен получить все зависимости, включая библиотеки разработки Qt 4.7, что избавит вас от сборки Qt.Затем просто выполните qmake quick3d.pro, чтобы использовать установленную систему qt.

Если вы действительно хотите собрать Qt (возможно, вам нужно иметь возможность помещать операторы qDebug () в библиотеки Qt), тогда вы можете использоватьисточники со страницы загрузок Qt или получить их от gitorious.Затем следуйте линии сборки (как описано в документации по сборке):

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

Qt3D регулярно тестируется на 64-битной версии, поэтому проблем не должно быть.
