!!! WARNING !!! =============== This is not the code you're looking for! The qt/quick3d repository has been deprecated. We have moved to a new repository in qt/qt3d. If you're working with Qt5 then to move from the (old) qml2 branch, use qt/qt3d and it will be built as part of the qt5 build (you'll be on branch: master). If you're working with Qt4.x you will now be working out of the qt4 branch of the qt/qt3d repository. So: For Qt5 - # get the sources - qt3d will be cloned as a sub-project cd ~/depot git clone ssh://codereview.qt-project.org:29418/qt/qt5.git cd qt5 ./init-repository # build - qt3d will be built as part of Qt5 cd ~/build mkdir qt5; cd qt5 ~/depot/qt5/configure make For Qt4 - # get the sources cd ~/depot/qt git clone ssh://codereview.qt-project.org:29418/qt/qt3d.git cd qt3d git checkout qt4 # build - using your Qt 4.8 cd ~/build/qt/qt3d ~/build/qt/48/bin/qmake quick3d.pro make
