Just a short notice that we have now closed the Lighthouse repository. Lighthouse was the research project aiming to make it easier to port Qt to different windowing systems and devices. It is now integrated into Qt 4.8, and it will be the foundation for Qt 5.
Lighthouse development now happens in the regular Qt repositories, and the Lighthouse master branch will no longer be updated. To avoid people accidentally being stuck on a dead branch, we have pushed one last commit to lighthouse/master, adding an #error to qglobal.h, which will cause a compile error for anyone who tries to use it.
