我尝试了从 GIT 构建最新 QT5-Alpha（http://qt-project.org/wiki/Qt-5-Alpha http://qt-project.org/wiki/Building_Qt_5_from_Git）的说明，但在 Wayland 中面临编译文件
Ubuntu Linux 11.10

在 qwaylandshmwindow.h:45:0 包含的文件中，来自 qwaylandintegration.cpp:46: qwaylandwindow.h:112:18: 错误：'wl_callback_listener' 没有命名类型
make[4]: *** [.obj/debug-shared/qwaylandintegration.o] Error 1_
有什么办法可以克服这个问题吗？
